Lifting up his hands towards the sky, Goku concentrates on drawing a massive amount of energy above his head. However, it takes time to draw it in, leading Goku to be wide open and stuck in place for several seconds. It is used in combination with the Spirit Bomb, drastically increasing its already great power.
In the Dragon Ball Super anime, Future Trunks uses this when he realizes during his fight with Fused Zamasu that he needs to acknowledge his weakness: his reliance on others. Once he acknowledges this weakness, he unintentionally used this move in which he gathered the remaining humans' energy through light and hope, creating a Spirit Bomb in which he absorbed and formed a sword with.
Video Game Appearances
Give Me Energy! was named in the Budokai Tenkaichi series and the Raging Blast series. In Dragon Ball Z: Budokai Tenkaichi 2, it is required to use the Spirit Bomb. However, it is not required in Dragon Ball Z: Budokai Tenkaichi 3, where all it does is power the Spirit Bomb for far more damage. The technique appears in Dragon Ball Z: Ultimate Tenkaichi as one of Goku's taunts that can be used when the character has low health.
In Dragon Ball: Xenoverse, it appears as GT Goku's Z-Soul, "Citizens of the universe, lend me your energy!". Equipping the Z-Soul greatly increases Super Spirit Bomb power and no damage is received while the Super Spirit Bomb is active. It also increases Stamina and Basic ATK by 5 and decreases Strike Supers by 2.
In Dragon Ball Xenoverse 2, Future Trunks uses this technique and collects energy from characters of several different timelines, due to the rift in time torn by Goku Black. With this he creates the Sword of Hope used to vanquish Fused Zamasu's body.
In Dragon Ball FighterZ, it appears as a Special Move for Goku (Base) under the name Everyone, lend me your energy!. Goku must use it to gather energy first in order to fire a Spirit Bomb though once gathered the the Spirit Bomb can be fired immediately or the energy can be held onto to fire the Spirit Bomb later.
