Game Boy Bomb
From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
Directory: Techniques → Offensive techniques
When Mister Satan confronted Majin Boo, he gave him a Game Boy Bomb (ゲーム ボーイ ボム, Gēmu Bōi Bomu) as a present. Majin Boo got frustrated, however, just as Satan began to trigger the bomb inside. Majin Boo threw it at Satan as it exploded. The World Champ's final plan backfired as Majin Boo instead stated, "That was a fun game!"
The attack also appears in Dragon Ball Z: Budokai onwards and Dragon Ball Z: Budokai Tenkaichi onwards. In the Budokai Tenkaichi video game series, it functions as a Blast 2 attack. It functions as his ultimate attack in the Budokai video game series. In Budokai 3, if the defending opponent's gauge is higher than the attacker's while this move is being executed then the defending opponent will throw the Game Boy Bomb at Satan just before the bomb explodes.
