Saiyan Power[1], known to the fandom as Zenkai (全開; lit. "Full Release" or "Full Throttle"), is a Saiyan genetic trait that allows their combat prowess to continually increase as they fight. This is done by the Saiyan instinctively imprinting on new experiences to lessen the chances of same injury happening again and likewise dramatically increasing their raw might after recovering from injuries.


After drinking the Ultra Divine Water and almost dying, Goku presumably got a power boost from not just the water's powers, but also from a Zenkai. He also possibly got one after his near death encounter with King Piccolo. During the Namek and Frieza Sagas, Zenkai is an extremely important element of the series, which allows Goku, Gohan, and Vegeta's powers to increase in order to "catch up" to Frieza and his men. After the Frieza Saga, most of the Saiyans had already become Super Saiyans. In the Cell Saga, when Cell returned from his botched self-destruction on King Kai's planet, his power amplified to the point that high amounts of energy surrounded his body to mimic the aura of a Super Saiyan 2.


Vegeta exploits Zenkai

Zenkai's power seems to increase exponentially after each use. When Vegeta recovers from his first fight with Goku, his power level went from 18,000 to 24,000, and another was received after being nearly killed by Zarbon's transformed state and healed in a Medical Machine. After Vegeta was near-fatally injured after fighting Recoome, his strength strangely skyrockets enough to have an even power struggle with Frieza's first form (stated to be 530,000), and another, final Zenkai increased his power enough to see Frieza's movements and Death Beams at first, before he begins to put in even more effort. Goku was able to tap into the power of Zenkai's during his gravity training (which in total boosted his power from "over 8,000" to 90,000), and again receives an enormous boost after recovering in a Medical Machine from his battle with Captain Ginyu (increased to 3,000,000).[2] To force a boost in power during the battle with Frieza, Vegeta tells Krillin to brutally injure him and have Dende heal him, which after greatly increased his power, though still not nearly enough to defeat the space tyrant (who by that point had just transformed into his most powerful state).

Goku Moving To Fight Frieza

Goku's Zenkai

Goku experiences a Zenkai upon eating a Senzu Bean in the movie Dragon Ball Z: Cooler's Revenge. In Dragon Ball Z: Broly - The Legendary Super Saiyan, it is stated that Broly survived his execution and grew stronger due to his Saiyan genes. In Dragon Ball Z: Broly - Second Coming, it is implied that Broly grew significantly stronger while in a coma for seven years after being beaten by Goku and recovering.

In Dragon Ball SuperGoku Black is able to upgrade his power through this ability following each battle against Goku and the other Saiyans, thereby obtaining his Super Saiyan Rosé and likewise enhance his techniques. It is also revealed that due to Goku and Vegeta having power in the realm of Gods and training past their limits, they are no longer able to gain Zenkais.

Video game appearances

In the RPG Dragon Ball Z: Super Saiya Densetsu, when a Saiyan reaches less than 5 HP, using a full heal item on him (like a card of Kami) will result in him receiving a Zenkai and raise his level by 1. This can be used early on against Raditz, to boost Goku's level extremely high. Also in the game, there is a glitch with Zenkai: if a player chooses to level Dende to level 3 (9999 exp earned twice), Dende can heal a character as well. Should he heal a Saiyan that is at 5 HP or below, the Saiyan receives the Zenkai, but not the level up. This allows certain characters like Gohan or Vegeta to be boosted to higher-than-usual power levels. Using the Moon Card on Gohan, however, restores his power level to the level it should be.

Broly is mentioned to have undergone another Zenkai after being blasted into the Sun in various video games, which resulted in him becoming a Legendary Super Saiyan 3.

In Dragon Ball Z: Battle of Z, a customize card named "Saiyan Power" can be equipped onto a character and raises their attack power every time they are knocked out. This card is based on Zenkai.

In Dragon Ball: Xenoverse, Zenkai is one of the Saiyan race's unique traits. When a Saiyan falls in battle, and is revived, either through teammate assistance or a Battle Item, they gain a large power boost that lasts for the duration of that battle. A Zenkai effect can be applied to non-Saiyans through Z-Souls such as Vegeta's "Saiyans are a Warrior race!" or through Super Perfect Cell's "That was a handy miscalculation".

"How many life-or-death battles have you been through? After all, Saiyans get stronger when they're on the verge of death. You keep getting stronger, too, so you must've nearly kicked the bucket any number of times, right? I've also nearly died... or should I say, actually died a number of times, heh heh heh."
— Goku talking about Zenkai with the Saiyan Future Warrior in Dragon Ball Xenoverse 2

In Dragon Ball Xenoverse 2, Saiyan characters can receive a Zenkai in the same manner as they did in Xenoverse.

During the Unknown History Saga, as Super Saiyan Xeno Bardock fights with Mira inside the time rift he had trapped himself and Mira within, Mira notices that Bardock is growing stronger as he fights and combined with the alterations Towa had done to his body while he was brainwashed as the Masked Saiyan, it is implied that it allows him to ascend first into Super Saiyan 2 and before finally transforming into his Super Saiyan 3 form, allowing him to defeat Mira before his mysteriously disappears from the time rift, leaving the defeated Mira behind but alive.[3]

As part of the Super Pack 1 DLC, Cabba grows stronger like other Saiyan characters do in Xenoverse 2. Interestingly, he will reference this after being revived by saying "I feel great!". This indicates the Saiyans of Universe 6 also possess the ability to receive a Zenkai like their Universe 7 counterparts.[4]


  • The term Zenkai is used in the first Dragon Ball Z ending theme, "Detekoi Tobikiri Zenkai Power!"
  • The Meta-Coolers' Auto-Repair Ability also corrects any flaw that allowed the unit to take damage, similar to Zenkai.
  • Hit's Pure Progress ability allowing him to grow stronger as fights is also similar to Zenkai.
  • In chapter 303, Vegeta states that a Saiyan cannot experience Zenkai if the wound is self-inflicted.
  • While the dub incorrectly implies that Zenkais only occur with Elite Saiyans, Goku, whom Vegeta and Nappa repeatedly refer to as a low-level Saiyan, receives them many times. This is confirmed by how Krillin states that it was weird how Goku always seemed to grow ever stronger after recovering from fighting devastating battles against powerful foes
    • In the anime, it is implied that Goku receives a Zenkai after eating a Senzu Bean after he injures himself with a Bending Kamehameha. However Goku may have received a Zenkai due to his injuries being the result of his extreme gravity training. It should be noted that this occurs before Vegeta reveals that it cannot be obtained by self-inflicted wounds.
    • However despite Vegeta's statement, Cell receives a Zenkai following the use of his Unforgivable! self-destruction technique (which technically qualifies as a self-inflicted wound). Presumably Cell's ability to do so is either the result of the process of gene-splicing used to create him or due to the mixing of Saiyan, Namekian, and possibly Frieza's race cells.
