"Stupid boy, you will pay! Yes, you're going to pay for everything you did to me!"
To perform the technique, Super Buu charges pink energy around him while saying "I'll make you pay!" and unleashes it in the form of a gigantic explosion with him as the nexus, yelling out "I'll Kill You!", inflicting a massive amount of damage.
Super Buu uses this technique against Gohan in the Fusion Saga. After being pummeled by Gohan's new strength, Super Buu comes up with a plan to defeat him, and uses the Revenge Death Bomber to blow himself up, knowing that he can regenerate after. Fortunately, Gohan saves Goten, Trunks, and Piccolo seconds before they are caught in the explosion. They assume that Buu blew himself up, though Gohan and Piccolo can still feel his energy. It is revealed later that the Revenge Death Bomber was a diversion so Buu can escape and come up with a plan, which is to trick Goten and Trunks to fuse into Gotenks, so he can absorb him, along with Piccolo, showing that Buu is smarter than what they had thought.
Appearances in games
"A move where you cause an explosion which also acts as cover! You can move freely while you are invisible."
— Dragon Ball Xenoverse in-game description
In Dragon Ball Xenoverse, it appears under the name Ill Bomber (イルボンバー) and is one of Super Buu's Super Skills. After blowing themself up, the user can move around and eventually they reform. While the Future Warrior can obtain this Super Skill as a reward in Parallel Quest 37: "Potara Warrior", it is racial exclusive to members of the Majin race because of its nature. While far weaker than the usual iterations and original depiction, it does not inflict damage on the user.
In Dragon Ball Xenoverse 2, Ill Bomber returns as one of Super Buu's Super Skills. It can be obtained by the Future Warrior (Xenoverse 2) as a reward in Parallel Quest 90: "Gathering of the Great Evil Alliance". Though it can be unlocked by a Future Warrior of any race it remains racial exclusive to Majins and functions just as it did in Xenoverse.
