The Key Sword (キーソード Kīsōdo) is a special type of weapon that appears in Dragon Ball Heroes.
Overview[]
The Key Sword is a golden blade consisting of a long handle and several gear-like parts, a red gem within a gear acting as a pommel, and a small golden spike protruding from the top of a semi-gear.
Usage[]
According to Mechikabura, the Key Sword was originally created by a god in order to seal the Dark Demon Realm. It is the manifestation of the "power of light", allowing it to restrain and purify darkness and grant its wielder increased resistance to darkness-based attacks.[1] The power of one Key Sword is such that even though Xeno Trunks could not damage Dark King Mechikabura with it, Mechikabura himself could not outright destroy it and opted to discard it in hopes of it becoming lost, fearing its future use against him.
The Key Sword appears to only be capable of manifesting from a preexisting sword, as Robelu was able to use her magic to transform Xeno Trunks's sword into it. A potential reason may be that Xeno Trunks, as a Time Patroller under Chronoa, may possess the "power of light" (which may also explain why Tokitoki could immediately change Xeno Trunks's normal sword into the Full Charge version of the Key Sword), though a true explanation is unknown.
Somehow, Robelu learned how to use her magic to summon the Key Sword. In the manga version of the Dark Demon Realm Saga, Robelu manifests the Key Sword from Xeno Trunks's sword. With the weapon's power, Xeno Trunks is able to suppress the power of the Hell Gates forming the barrier protecting Mechikabura's Tower, as well as the strength of the Demon Gods guarding them from within. During his fight against Brainwashed Berserk Chronoa, Super Saiyan 3 Xeno Trunks uses the Key Sword's power to sever the power of darkness from Chronoa, freeing her. However, he is unable to hurt Dark King Mechikabura in his base form while wielding the Key Sword, resulting in Mechikabura tossing the sword away in hopes of it being lost. Later, Xeno Goku finds it and brings it with him to the final battle against Time Power Unleashed Dark King Mechikabura. Super Saiyan God Xeno Trunks reclaims it and fully charges it with the help of Chronoa, Tokitoki and Demigra, ultimately using it to seal Mechikabura away. Afterwards, Xeno Trunks's sword reverts to normal.
In the game version, Xeno Trunks loses the Key Sword while scaling Mechikabura's Tower. Xeno Bardock eventually finds it during his battle with Dark Broly and uses it to defeat the berserk Saiyan and free the Time Patrol from Mechikabura's void. Chronoa later retrieves the sword to give to Xeno Trunks, resulting in Mechikabura's defeat.
During the Demon Invader Saga, Tokitoki transforms Xeno Trunks's sword into the Key Sword again, allowing him to ignore the Ozotto clone of Chronoa's Time Freeze and freeze the clone in turn, giving his allies the opening to blast Ozotto off of Chronoa.
Enhancements[]
Full Charge[]
Super Saiyan God Xeno Trunks unleashes the Key Sword
After being fully charged by the "power of time", the Key Sword transforms. Its color becomes crystal blue and the front blade is extended to form a true blade, in addition to the front design forming a complete gear and extending into a sort of crossguard. Crystal blue chains additionally wrap around Trunks' arm to secure his grip.
In this state, the Key Sword's user becomes immune to time-based techniques such as Time Freeze. Additionally,
Super Saiyan God Xeno Trunks first used the fully-charged Key Sword, channeling not only his divine ki and Time Power Unleashed Chronoa's power of time but also those of light and darkness from Demigra to seal away Time Power Unleashed Dark King Mechikabura. In the game, it also sealed away Mechikabura's youth.
Later, Tokitoki charges Xeno Trunks's sword into the fully-charged Key Sword to help him and the rest of the Time Patrol free Chronoa from Majin Ozotto.
Video Game Appearances[]
In Dragon Ball Heroes, the Key Swords appear as items during the missions of the Dark Demon Realm Saga where they are used by the Time Patrol to seal the Hell Gates opened by Towa in the Hell Gate Assault Saga. The player starts each battle in that saga in possession of a Key Sword, and at the end of their attack phase can attack the enemy using the Key Sword. If the player wins the Charge Impact, the enemy is pierced by the Key Sword, which causes damage, halves their Guard and increases their Charge Impact speed. The Key Sword can be stolen from the person holding it if they lose a Charge Impact while defending. Winning a battle while holding a Key Sword will award the player with a Dragon Ball.
The Key Swords later reappear as items during the missions of the Dark King Mechikabura Saga, where each member of the Time Patrol-Demigra Army alliance is given one by Demigra to close the Hell Gates protecting Mechikabura's Tower.
Universe Mission 9 introduced the Key Sword Lock (キーソードロック) CAA type, which can be used once per battle from Round 1 onwards if the enemy team has at least five members. When activated, the user will lock onto a specific enemy and fire several spectral Key Swords at the target. If the target fails the Charge Impact, the target's abilities are sealed for the next round, in addition to any effects specific to the user's CAA.
Xeno Trunks uses his fully charged Key Sword first to seal Mechikabura's Time Power Unleashed form, giving Xeno Vegito the opportunity to hit him hard enough to revert him to his base form. Xeno Trunks then seals Mechikabura's youth, further weakening him enough for Chronoa to seal him away in the Labyrinth of Light.
Trivia[]
- Its name and design are likely a reference to the Keyblade in the Kingdom Hearts franchise.
