Bonk's Revenge (JP: PC Genjin 2) is a prehistoric platformer and the second title in the TurboGrafx-16 Bonk trilogy. The player, as the caveman Bonk, must fight his way through several stages to defeat his old nemesis King Drool and recover the missing half of the moon, which Bonk visited at the end of the original Bonk's Adventure.
The game was eventually adapted to the Game Boy with several significant game changes. The TG16 version was ultimately rereleased on Nintendo's Virtual Console. It is also on Japanese PSN and appeared in a TurboGrafx-CD compilation with Bonk's Adventure, Bomberman and Gate of Thunder.
