Revenge Death Bomber
From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
Super Boo says, "I'll make you pay!" as he charges pink energy around his body. He then shouts, "I'll... KILL YOU!" and expels an enormous pink explosion, inflicting a massive amount of damage.
Dragon Ball Z
Super Boo used this attack in his battle against Ultimate Gohan. Fortunately, Ultimate Gohan saved Piccolo, Son Goten, and Trunks, seconds before they were caught in the explosion. It was later revealed that the Revenge Death Bomber had been a diversion so that Super Boo could escape and wait for Goten and Trunks to be able to fuse again into Gotenks.
It later appeared in the Raging Blast video game series.
