"Set off an explosion at your enemy's destination. A long-range attack!"
In most instances this attack has done very little damage, however it appears that, unlike Goku, Shin has a relatively powerful version, as he actually expected the blast to hold Majin Buu at bay. Despite not actually causing damage to an opponent, it is shown to be capable of destroying objects or causing damage to terrain it hits. Later in Dragon Ball Super, Jiren is shown to be capable of using this technique with extreme ferocity, being capable of deflecting an opponent's attacks and even counterattacking with it.
Usage and Power
The invisible eye blast has been used several times in the series. The first time it is used is during the Frieza Saga, after Vegeta just died from Frieza's Death Beam, Goku uses the invisible eye blast to dig a hole to bury Vegeta's corpse in. A little later, Frieza uses this technique against Goku, but Goku counters with the same technique, which ends up being thrown into the sea.
The technique is used is by Shin against Majin Buu, expecting it to hold him. However, it proves useless, as Majin Buu is only temporarily disoriented. Thanks to Majin Buu's ability to instantly learn any technique he observes, he returns the attack and sends Shin flying. Soon, when Gohan is hit by Majin Buu's Vaporize! and is headed for outer space, Shin uses his invisible eye blast to destroy the energy ball, saving Gohan's life by a thread.
In Dragon Ball Super, Goku Black, in the manga, used this technique to repel Future Mai during her attempted assistance for Future Trunks. During the Tournament of Power, Jiren's usage of this technique is so potent that it is able to repel an assault from Hit, and deflect attacks as powerful as the Universe 7's Spirit Bomb and later Super Saiyan God SS Evolved Vegeta's Final Flash. Jiren was also able to stop True Golden Frieza's attack in mid air before knocking Frieza away and out of his golden form. At Full Power, Jiren's glare can stop three energy blasts at the same time and blow everyone away.
On M-2, Pan uses the technique to destroy an alarm. Perfect Cell uses an invisible eye blast in Hell to knock the Ogres away before he and Frieza fight Goku. The final time the invisible eye blast is used is in the Shadow Dragon Saga in Dragon Ball GT, when Goku and Vegeta fuse into Super Saiyan 4 Gogeta to battle Omega Shenron. Gogeta uses the invisible eye blast to flaunt his superior power, giving Omega Shenron a nose bleed afterwards.
Video Game Appearances
This technique makes its first video game appearance in Dragon Ball Z: Hyper Dimension as Majin Buu's long distance punch attack, standing and crouching.
In Dragon Ball Xenoverse, it is called Evil Eyes and is one of Piccolo's Super Skills. The skill can also be obtained by the Future Warrior as a reward in Parallel Quest 13: "Tri-Race Co-op". In the game, it functions similarly to Vegeta's Flash Strike skill as they both set off an explosion at their opponent's location; the only difference visually is Evil Eyes has no hand gesture, as it is fired from the user's eyes. Unlike other depictions in the series, in Xenoverse it is capable of causing damage to an opponent. It is also appears as one of the techniques used by Nuova Shenron and Eis Shenron.
"Creates Ki that explodes in the path of an opponent."
