"You know you can't win! You can't destroy what I really am! Even if you manage to kill this body, someone even stronger would surface and take my place! Not one death will go unaccounted for, not one!"
— Dragon Ball Z: The History of Trunks

Future Gohan (未来の孫悟飯, Mirai no Gohan) is the alternate timeline counterpart of Gohan that appears in the timeline in which Future Trunks lives.^[4]

Far more serious and aggressive than his present timeline counterpart, Future Gohan is showcased as a twenty-three-year-old man and is depicted as the mentor of Future Trunks. After his father dies from a heart virus and cannot be wished back with the Dragon Balls, due to his death being a natural cause and the murder of the Z Fighters at the hands of Android 17 and Android 18 six months later, Gohan becomes Earth's last line of defense. Now a Super Saiyan, he spends the following thirteen years attempting to take down the androids, all the while training Future Trunks in the hope that he may one day be able to defeat them.

Appearance

Screenshotsdbztvspecial2 175 — Future Gohan before acquiring his facial scar

Future Gohan appears as a tall, stern, and muscular man. He also dons a uniform greatly resembling that of Goku's early uniform, and states that he is inspired to wear it in the hopes that he will one day be as strong as he was. In the Japanese version, Gohan states that he made it so that he can be as strong as his father while in the English version, Gohan never explained where he got the Gi. The only differences between his uniform and Goku's is that the sleeves are longer on his, his boots are a dark blue with yellowish stripes on the bottom edges and without the line running in the middle of the boots from top to bottom, and he also wears his own kanji symbol on the back, Han, 飯.^[5] Bulma even states that Gohan looked strikingly similar to Goku when wearing this uniform. He never changed his hairstyle since his childhood, but the longer part of his hair is cut much shorter, somewhat resembling the haircut his alternate past counterpart had when he first trained in the Hyperbolic Time Chamber, and when fighting with Cell, only it was more grown into (because Future Gohan was a full-grown adult). He also obtains a scar that runs down the left side of his face, the after effect of an injury sustained during a battle with the androids that also cost him his left arm.

Personality

Due to the apocalyptic world that he spent the latter half of his life in, Future Gohan is shown being very serious and more aggressive than his present timeline counterpart, who was quite naive, awkward, and more laid-back and comical (especially when donning his Great Saiyaman outfit), but does retain his calm and joking nature, much like his father and present counterpart. Future Gohan is shown to be in quite a bit of pain and stress after all the years of challenging the androids alone, and has a sort of "do or die" attitude, Future Gohan fiercely hates the Androids, for killing his friends and, specifically, Future Piccolo, much like his present timeline counterpart hated Cell and his Cell Juniors, who are also Androids, for killing Android 16, another android, and injuring his friends, but, unlike the former, the latter's hatred is so fierce to the point that he wants to see Cell suffer, and mercilessly destroying the Cell Juniors without hesitation, also, unlike Future Gohan, Present Gohan was in good terms with Android 18 in the Buu Saga, because his friends and Piccolo were alive and well, and unlike Future Gohan, who was in sorrow seeing his father dead, Present Gohan was happy because of his father's death (due to his self-sacrifice, not the Heart Virus).

However numerous times he appears to hide it, let go, and just enjoy life for what it is worth, most notably when telling Future Trunks to forget about becoming a Super Saiyan until he knows he is ready (in the anime special). Future Gohan also is incredibly close to Future Trunks, and appears to even consider him as his little brother. He also appears to be deeply angered by the deaths of his close friends, which is told out loud to Future Trunks by stating that he remembers back to how the androids killed Future Piccolo and Future Krillin when transforming into a Super Saiyan.^[4]

Although he once shared the same dream as his mainstream counterpart of becoming a scholar, due to the apocalyptic event that took place, Future Gohan presumably never went to school to fulfill that dream. It is assumed he spent all of his time training and pondering ways in which to stop the androids, making him a complete warrior instead of the scholar his present timeline counterpart becomes in late Dragon Ball Z, Dragon Ball Super, and Dragon Ball GT. But Future Gohan said to Future Bulma that he always dreamed of being strong like his father meaning he never wanted to be a scholar anyway. However, he is unable to receive the ample training with Goku like his present timeline counterpart does, and he was unaware of and never reached any levels higher than the basic unmastered Super Saiyan, meaning, throughout his entire life, he is always an unmastered Super Saiyan, he never trained himself to, at least, master the form and nullify its negative setbacks to negligible amounts, like Present Gohan who achieved Super Saiyan Fourth Grade and later Super Saiyan 2 during his fight with Cell and had his potential released by Old Kai to face the more terrible Super Buu and, therefore, Future Gohan is never able to reach anywhere near his full potential,^[6] , as his present counterpart did, which leads to his miserable defeats, and ultimately his death, against the weaker Androids of the future ^[4]^[7], while Super Saiyan 2 Gohan easily dominated and eventually kills the even more evil Perfect Cell, who also came from the future and was exceedingly more powerful and more sinister than the Androids Future Gohan fought (as Cell even attempted to destroy the solar system and wreak havoc in the universe, and if he had succeeded, then the apocalyptic world Trunks' future suffered from will not only repeat itself, but would grow even worse, something that the future Androids could not possibly do, and he even managed to kill Future Trunks with a Death Beam, although he was just firing randomly, as the Androids of his timeline failed to kill Trunks) .

In Dragon Ball Xenoverse 2 we learn a bit more about Future Gohan's personality. He is still highly intelligent like his maintimeline counterpart, able to quickly figure out that the Trunks that assisted him is from the future and also was able to learn that his fateful encounter with the androids has a purpose. Later when Xeno Trunks alters the course of history for this timeline causing Future Gohan to actually destroy the androids, Gohan mentions that he is looking forward to taking a break and enjoying the peace but mentions he will still defend and protect the world with Xeno Trunks, officially taking over his father's role in the greatly altered Future timeline.

Biography

Earth's final hope

Main article: Dragon Ball Z: The History of Trunks

"Now Gohan... what would your father do!?"
— Future Gohan questioning himself after he and Trunks are nearly killed (FUNimation dub)

GohanFutureKidGokuDies — Young Future Gohan discovers his father has passed away, an event that would impact his entire life

The point of timeline divergence with Future Gohan and his main timeline counterpart occurred when Future Frieza arrived on Earth in August of Age 764. Originally, Future Goku uses his Instant Transmission technique to arrive and kill Frieza and his father (Goku even states to Future Trunks in the main series that was what he was going to do), but the events in the series differ, as Future Trunks arrives and kills the tyrants instead of Goku, thus the timeline divergence.^[8] Future Gohan hails from the true original timeline (one without a Future Trunks coming back in time, obviously) and because of this, the events that unfold are far different from those in the main series.

GohanFutureFutureTrunksTraining — Future Gohan training with Future Trunks

After the death of his father due to a lethal heart virus in Age 766, and then the murders of the Z Fighters by the androids on May 12th, Age 767 and the Dragon Balls becoming useless forever, due to Future Piccolo's death and Future Kami's death as the Z Fighters are unable to be wished back to life, Gohan's life is altered drastically.^[9] It is stated that the death of Gohan's friends, like Future Piccolo and Future Krillin, sparked his transformation into a Super Saiyan, in these events, he never met Videl (as Present Gohan did), nor went to school to fulfill his dream to become a scholar, making him completely a warrior, thanks to Future Trunks' Time Machine, Gohan's character and life is split into two different timeline incarnations (with the aforementioned Gohan who lived in a peaceful world and the Gohan featured here in an apocalyptic timeline)

Over the course of the following thirteen years, Gohan trains himself to be able to take down the androids, and over time, develops a close relationship to Trunks, the son of Vegeta and Bulma. As the last remaining Z Fighter, and by extension, family member generation (because he never met Videl, or started a relationship with her) he continuously takes it upon himself to challenge the androids, even though he is outnumbered and outclassed. Gohan becomes a Super Saiyan sometime during the years-long struggle against the androids. In the special, Trunks also states that being a half-Saiyan hybrid like himself, Gohan must understand how he feels about not being able to stop the androids, and while he does, Gohan still states that Trunks is currently an emotional wreck like he was when he was not allowed to train and fight with his friends.

Future Gohan's first true appearance in the special is his arrival at a city the androids had just recently attacked, thirteen years after the Z Fighters had been killed. He encounters Future Trunks in the ruins of the city, and after hearing his plea to learn to fight, agrees to take him under his wing.

GohanFutureVsFutureAndroid17 — Future Gohan engages Android 17 in battle

During a day of relaxation, the androids attack the theme park Super World while Gohan and Trunks happen to be flying overhead. The two quickly head toward the park to battle the androids. Upon arrival, Gohan instructs Trunks to stay out of the fight. Gohan then battles with Android 17, transforms into his Super Saiyan form and despite a few lucky hits from Android 17, quickly gains the upper-hand. However, Android 18 soon intervenes and Gohan finds himself quickly overwhelmed. In an attempt to assist Gohan, Trunks rushes in only to be quickly defeated by Android 18. However, before Android 18 can deliver a powerful energy blast to the young warrior, Gohan rushes in and takes the attack for him, saving Trunks' life. Gohan then carries the unconscious Trunks while trying to find a place to hide. He is successful in hiding until the androids decide to bomb the entire area in hopes of driving them out. Gohan manages to protect Trunks and stay hidden, but at the cost of his left arm, which is completely blown off in the bombing.

Merely one Senzu Bean remains in Gohan's bag and rather than use it to restore his arm, he chooses to give it to Trunks, which saves him from death. Trunks awakes a moment later and brings the unconscious Gohan back to Capsule Corporation where Bulma treats his wounds. After Gohan's injuries heal, the two resume training. Trunks, pushing ever closer to becoming a Super Saiyan, quickly begins to improve day by day.

The end of a hero

"Sorry about that Trunks, but I wouldn't be able to forgive myself if anything happened to you. This is my battle for now little brother, you're not quite ready yet. I can feel them all crying down there Trunks, that's why I have to go! I know you'll understand someday. See ya later kid..."
— Future Gohan saying goodbye to the unconscious Trunks (FUNimation dub)

GohanFutureSSINV — Future Gohan prepares for his final battle against the Androids

Several time later, during a day of training, the nearby Pepper Town is attacked by the androids. Gohan prepares himself for battle, only to see young Trunks begging to fight alongside him. Gohan seemingly accepts, only to knock Trunks out to avoid the young warrior from being nearly killed again, or worse. The one-armed Gohan seals his final fate when he flies into the city alone and ambushes the androids. Despite his handicap, Gohan puts up a long, suspenseful fight against the combined power of the androids.

GohanFutureDiesN — Future Gohan is killed by the androids

As Gohan tries his hardest to keep his defenses up, the androids then blast a building when Gohan is trying to keep his defense up, interrupting his vision. The two androids then knock Gohan down and continuously blast Gohan with continuous energy waves, killing Gohan. Trunks awakens when Gohan's ki depletes. He then searches the city, only to find Gohan's dead body laying in a pool of blood and water. His rage bursts out and he transforms into a Super Saiyan for the first time.

It is to be noted that in the manga chapter upon which the special is based, not only was the first battle against the Androids (where Gohan obtains his facial scar and severed arm) never shown, but Trunks was already able to transform into a Super Saiyan, and Android 18 presumably never joins the battle, as Android 17 mockingly brags that he only used under half of his maximum when he defeated Gohan over a year ago, and kills him with ease before Trunks is able to awaken and find Gohan's corpse in the debris (also notable is that no rain is ever seen during this scene, although Trunks ramming his fists into the ground in frustration is shown, if much less accentuated).

Appearance in Trunks' flashback

Main article: Ghosts from Tomorrow

"If my father were still alive, he'd know what to do. Ah Dad, I always thought you were invincible, at least to a virus. But I'll be brave for you Dad... I'll make you proud."
— Future Gohan's flashback (FUNimation dub)

GohanFutureFutureTrunksVsAndroidsGhostsFromTomorrow — Super Saiyan Gohan and Trunks charge the Androids in a desperate attempt

In the Dragon Ball Z episode "Ghosts from Tomorrow", a flashback via Trunks showcases Future Gohan waging a battle against Androids 17 and 18. In the flashback, Gohan battles with Android 18 first, but despite a few good blows, he is eventually smashed into a rock pile when Android 17 intervenes. Before the downed warrior can rise again, the androids prepare to assault him, but Trunks steps in and cuts off a few locks of Android 18's hair. Trunks is attacked but Gohan is able to save him.

GohanFutureGhostsFromTomorrowFlashback — Future Gohan as he is seen in the flashback, just prior to engaging the Androids

However, he is quickly overwhelmed so he and Trunks hide among the ruins of the city in order to devise a plan. A flashback of Gohan picturing his dying father is shown, and he states he will strive to make him proud. The next scene shows Gohan and Trunks charging at the androids, but nothing beyond this is seen other than a large explosion and Trunks' narrative describing his mentor's death. The scene has many similarities to the TV special, and may display the basis of it in a nutshell, but the scene does differ. It is often debatable if the differences in the flashback was because it was a fight not seen in the special, that the animators made a mistake, or Trunks' flashback was just interpreted different (if in-universe description counts). Nevertheless, this episode of Dragon Ball Z premiered in Japan on November 11, 1992, before "The History Of Trunks" special aired in Japan on February 23, 1993.

Super Saiyan Future Gohan going to face the androids

Like what was seen in the TV Special, Future Gohan appears in Dragon Ball Super during Future Trunks' flashback. In it, Gohan is with Trunks sit down when the androids attack a city nearby, Gohan transforms into a Super Saiyan and asks Trunks to stay, but he refuses and wants to go with his master, Gohan agrees and when both prepares to go, Gohan knocks Trunks out and goes by himself to face the androids. Later, Trunks finds Gohan's dead body, much to his sadness and begins to cry, achieving for the first time his Super Saiyan transformation.

An image of Future Gohan appeared when Gohan arrived to wave Trunks goodbye, causing the latter to reminisce the times he and Future Gohan shared. A tearful Trunks dwells on his failure to protect his world, but was cheered up by Gohan's optimistic words.

Dragon Ball Super

Although only appearing in flashbacks, Future Gohan's spirit was likely destroyed when Future Zen-Oh wiped out Future Trunks' universe to eliminate Zamasu once and for all. In the second future timeline, his spirit continues to exist, but cannot be revived because the Dragon Balls are still disabled, as Future Piccolo still remains dead by the time that second timeline was created, although it is possible for Future Trunks to revive his mentor with the Super Dragon Balls, but did not do so, due to him and his mother being unaware that those sets of Dragon Balls exist and thus, Future Bulma never invented the Super Dragon Radar like her present timeline incarnation did.

Power

Manga

Before his eventual death, Future Gohan is arguably the most powerful warrior left on Earth, but is weaker compared to his present timeline counterpart (who was more younger yet more powerful than him, due to his training in the Time Chamber with his father, thus giving him more access to his latent power) when he fought the immensely powerful android Cell (who absorbed the present timeline incarnations of Future Gohan's killers of his future timeline). In the manga when Future Trunks attained his Super Saiyan form, he struggled against Future Gohan's base form. Future Gohan states that he wished he was as strong as his father, like his present counterpart was, but later surpassed his father during and after the Cell Games, but it was not an easy task (Future Gohan never surpassed his father in power, due to his inexperience, and not training with him in the Time Chamber to master the Super Saiyan form, due to his death), and also that Future Trunks would surpass him in a few months. Future Android 17 claims to Future Gohan that when he had previously defeated him he had not even used half of his power.

Anime

In the History of Trunks, Gohan seemed to have gotten stronger via Zenkai as he was able to hold his own against both androids for some time despite having one arm, unlike their last encounter in which he could not hold his own at all with both his arms, but once the Androids team up and use their Accel Dance, he was soundly overwhelmed, while in the present timeline, Super Saiyan 2 Present Gohan easily overpowered and slaughtered every last one of the seven Cell Juniors singlehandedly, each in one blow (as they have nearly the strength of Cell himself), despite using their most powerful attacks and teaming up on him, Gohan just shrugged it off as if nothing happened, unlike Future Gohan, who suffered grievous injuries and pain when being hit by the future Androids' ki attacks, Gohan even managed to defeat Cell with only a right arm-powered Kamehameha, after a long and painstaking Beam Struggle (because he lost the use of his left arm at the time), something a one-armed Future Gohan cannot do against the weaker Androids, although he managed to overpower them with his own right arm-powered Kamehameha in a Beam Struggle against their Non-Stop Violence. Before Future Trunks departs to the past, Future Bulma tells him that he is only about as strong as Future Gohan was at the time of his death. Hypothetically, if he was still alive and, instead of facing the androids everyday, he should have went to the Sacred World of the Kais to train with the Z Sword, breaks it, and had his power awakened by the released Old Kai, then a hypothetical Potential Unleashed Future Gohan would have dominated and taken down the Androids very easily on his own without even transforming into a Super Saiyan (Like his present counterpart did with Super Buu), so he must have the same vast dormant power as Present Gohan had, but never released all of it, due to not training with his father, Shin never visiting the Earth, combined with his death at the androids' grasp before he can even release at least half of his dormant power (his Potential Unleashed state only appeared in the video game Shin Budokai - Another Road).

Video games

In one of the two secret alternate endings of Dragon Ball Xenoverse 2, Xeno Trunks interferes with Future Gohan's fateful battle and an emotional Xeno Trunks is almost killed. This causes Future Gohan's power to explode giving him more than enough power to defeat and destroy the androids, bringing peace to that timeline's Future World.

Techniques and special abilities

File:Gohan One Arm Kamehameha.jpg

Future Gohan prepares his Down Burst counterattack

Flight – The ability to fly with the use of ki.
Ki Blast – The most basic form of energy wave.
Down Burst – A counterattack used by Future Gohan where he fires an energy sphere to the ground in order to get away from his opponents. it is Future Gohan's signature attack in Raging Blast 2.
Intercept – A counterattack used by Future Gohan where he moves quickly and gets behind the opponent to deliver a kick to his chin.
Sonic Rush - A physical rush attack used by Future Gohan and named in Xenoverse 2.
Masenko – A yellow wave of ki shot from one hand on top of the other. Future Gohan uses this technique in an anime flashback and as one of his Blast 2 attacks in his base form in the video game Dragon Ball Z: Budokai Tenkaichi 3 (he only uses his right hand in the video game for this attack though). In the 8th Dragon Ball Z Movie, Future Trunks is shown using the Masenko with the present Gohan as Super Saiyans, suggesting that it may have been Future Gohan who taught him the move.

GohanFutureKamehamehaWaveAndroids — Super Saiyan Future Gohan fires his Kamehameha at the Androids

Kamehameha – A blue and white energy blast. This attack is seemingly taught to him by his father. Future Gohan uses the Kamehameha in the special when he battles the androids the second time. He also uses the Super Kamehameha variation as his Ultimate Blast in his base form in Budokai Tenkaichi 3 and in Dragon Ball Heroes. He uses it one-handed despite having both arms in video games, making it reminiscent to the loss of his left arm in the manga/anime.
Super Explosive Wave – A wave of energy more powerful than the simple Explosive Wave. Future Gohan's version of the Super Explosive Wave looks very similar to Piccolo's Hyper Explosive Demon Wave. It is used by Future Gohan in his base form in Budokai Tenkaichi 3 and Raging Blast 2.
Full Power Charge – One of Future Gohan's Blast 1.
Wild Sense – One of Future Gohan's Blast 1.
Special Beam Cannon – A purple and yellow ki wave shot from two fingers. He never used this technique in the anime (much less the manga, where we never even see him attempt a blast), but it is apparent that it may have been taught to him by Piccolo. Future Gohan uses this technique in the third Budokai Tenkaichi game and the second Raging Blast game while in his Super Saiyan form and in Shin Budokai 2 in his base form.

Special beam cannon — Future Gohan using the Special Beam Cannon in *Raging Blast 2*

Gekiretsu Madan – One of Future Gohan's Blast 2 attacks in his Super Saiyan form. Called Hyper Masenko in Raging Blast 2.
Fierce Combination – Future Gohan's Ultimate Technique in video games. The attacks performed in this rush are taken from his fight with the Androids and his younger counterpart's fight with the Cell Jrs. and Super Perfect Cell in the main timeline.
Burning Attack – Used in the PSP game Dragon Ball Z: Shin Budokai - Another Road. This move is originally used by Future Trunks in the manga/anime.
Evil Barrier – A green energy shield, Gohan used this ability against the androids and in the third Budokai Tenkaichi game in his Super Saiyan form.
Power up to the Very Limit – One of Future Gohan's Blast 1 in his Super Saiyan form.

Transformations

Super Saiyan

Main article: Super Saiyan

GohanFutureFinalBattle — Future Gohan as Super Saiyan

The ability to transform into a more powerful being, Future Gohan takes this form every time he fights the androids. It is not exactly clear at what age and how he became a Super Saiyan in the alternate timeline, but it he might have became a Super Saiyan after seeing his friends killed by the androids, as suggested by his fierce hatred towards them. He also attempted to teach the ability to Future Trunks and succeeded in the manga, but in the anime it is his death that prompts Future Trunks' transformation.

In Dragon Ball: Xenoverse 2, Future Gohan's version of the Super Saiyan form is named Future Super Saiyan, as Future Gohan and Future Trunks has this transformation, and the Saiyan Future Warrior (Xenoverse 2) upon completing the second alternate ending in the story after collecting all 5 Distorted Time Eggs and completing Bardock's fight with Mira. This version of the Super Saiyan form has greater ki recovery compared to the standard Super Saiyan and Super Vegeta forms.

Super Saiyan 2

Future Gohan can take this form in the video game Dragon Ball Z: Shin Budokai - Another Road. Much like his present counterpart as a young adult, with the exception of lightning electricity appearing with his aura, his appearance in this form looks very similar to his appearance as a Super Saiyan.

Super Saiyan 3

Main article: Super Saiyan 3

Future Gohan can take on this form in the arcade game Dragon Ball Heroes, introduced in ninth mission of the Galaxy Mission series (GM9). Unlike Bardock and Goku, Future Gohan has two bangs, instead of just one.

Potential Unleashed

Future Gohan after his potential was unlocked

Like his present counterpart in the main timeline, Future Gohan has his hidden potential awakened by the Future Old Kai during the battle against Future Majin Buu in the video game Dragon Ball Z: Shin Budokai - Another Road. Like every other playable character in Budokai Tenkaichi 3, Future Gohan can also get his potential unlocked by Old Kai in the Sim Dragon. This form does not change his appearance beyond gaining more prominent facial features.

Fusions

Main article: Future Gohanks

Future Gohan can fuse with his student Future Trunks, resulting in a powerful warrior that attends by the name of Future Gohanks. His regular design comes from Dragon Ball Heroes to appear exclusively in Dragon Ball Fusions through a special collaboration between both games.

Trivia

Future Gohan is the first adult version of the character seen in both the manga and anime.
On the front cover of the special Future Gohan is already shown having lost his left arm. At first sight, this is hard to tell because Future Trunks partially covers Future Gohan, particularly where his left arm is supposed to be. This layout is applied most probably in order to evade this major spoiler, besides, the scars from that battle are also present.
After an encounter with the androids, Future Gohan received scars that looked similar to Yamcha's. His haircut even vaguely resembled the one Yamcha was seen with in his appearance during the Majin Buu arc.
Future Gohan has a monstrous appetite similar to Goku's and devours his meals very quickly. Future Bulma even says when Future Gohan has finished eating, "Yep, like father like son." Humorously, his present counterpart is shown swallowing food the same way during the Majin Buu arc in the World Tournament saga.
The manga implies that Future Gohan would not have stood a chance against the Androids, even with both arms, as Future Android 17 stated he only used less than half his full power previously.
Future Gohan presumably was the one to train Future Trunks, in the art of swordsmanship.
- In Supersonic Warriors 2, Future Trunks admits to Gohan that his Future self was the one that taught Future Trunks.
Future Gohan is voiced by Dameon Clarke (the voice actor of Cell, an Android) in the anime, but is later voiced by Kyle Hebert (his present timeline counterpart's adult voice actor) in various video games.
Coincidentally, both Future and Present Gohan had lost the use of their left arm during a battle against an Android (Future 17 and Future 18 for Future Gohan and Cell for Present Gohan), while Future Gohan had lost his arm completely, Present Gohan's wasn't, it was badly injured after taking a powerful blast from the evil Bio-Android, but soon recovered after Cell's defeat, and would continue to fight with both of his arms.
- Again, coincidentally, both Gohans used a right arm Kamehameha and overpowered the respective aforementioned Androids they were fighting, although Present Gohan's lasted much longer and more painstakingly and it took a decent struggle and his father's spirit's assistance with some distraction from the Z Fighters, and Vegeta, to unleash his full power and decimate Super Perfect Cell once and for all.
- Also, while the right-handed Super Saiyan Future Gohan failed to defeat the weaker Androids, the right-handed Super Saiyan 2 Gohan managed to kill the overwhelmingly powerful and evil Super Perfect Bio-Android, which effectively, and technically, eliminating the Android threat of his timeline, indeed, the present timeline incarnation of Trunks' mentor was the one who saved his timeline's future and finally surpassed his father in power.
- It was Future Gohan's pupil Future Trunks that finally ended the Android threat in his timeline that brought peace to his future, thus finally fulfilling his wish of someone even stronger than him rising in his place to defeat the Androids, in which Trunks eventually succeeded while Gohan had failed.
