Bonk's Revenge (PC-原人 2, or PC-Genjin 2 in Japan) is a 2D platformer set in prehistory, originally for the TurboGrafx 16 console, created in 1991 by the Red Company for Hudson and Turbo Technologies, and licensed by NEC. This is the second title in the Bonk series and it was re-released for the TurboGrafx-16 in 1992 on the Gate of Thunder 4-in-1 game CD-ROM. A completely different game with the same name appeared on the Game Boy, whereas the original version was re-released for Wii Virtual Console and on the Japanese PlayStation Store. It was also released in Japan on Windows Store on December 13, 2013 and on Wii U Virtual Console on March 12, 2014.

This time, the titular large-headed caveman is on a quest to recover half of the moon, which was stolen by the evil King Drool III. Its multiple stages each contain several specific areas, which range from outdoors to trains to space to underwater. As in most platformers, Bonk has several crucial abilities: the I button causes him to jump; the II button causes him to "bonk," an action in which Bonk slams his head forward, inflicting a killing blow on most enemies; I jump-II combo causes Bonk to head-butt the Earth, killing enemies he lands on and creating a damaging shock wave; Holding down the II button in midair causes Bonk to spin and hover, allowing for long, controlled jumps. Bonk can also use his large mouth to grip onto allowed surfaces for climbing.

Bonk's health is reflected in heart containers, similar to games in the Zelda series. Taking damage will cause Bonk to lose a certain amount of hearts, and hearts can be refilled through items, such as fruit, collected throughout the game. Bonk can also attain blue hearts that increase his amount of hearts, allowing him to effectively gain more health as the game progresses. The game also features Smileys, similar to coins in the Mario series, which are helpful when you get to the bonus round after each boss because you can get extra lives. Bonk can also turn invincible when he collects a large meat or two small meats, and can gain an extra life when he collects a small model of himself.
