Dopefish

Dopefish
The Dopefish is a buck-toothed green fish. Most of its attacks consist of some form of biting the opponent. Different speeds of bites do different damage, with the slowest bite, if successful, automatically killing the opponent. All of its attacks can be cancelled by the opponent in mid-bite, resulting in the Dopefish being stunned. The Dopefish's supers consist of cameos from the Demented Cartoon Movie, including the Zeeky H. Bomb and Kamakazee Watermelon. The Dopefish will often belch as an introduction, as a taunt, as a victory pose, as a death cry, as well as after eating the opponent. Slippery water-like controls and slow attacks make controlling the Dopefish difficult, but his one-hit-kill move can turn the match around.

The dopefish originates from Commander Keen: The Secret of the Oracle, a famous platformer game by Apogee Software.
