The Biolizard is a fictional character and final boss of the Sonic the Hedgehog video game Sonic Adventure 2.

Character history
The Biolizard is the prototype of Project Shadow, an experiment conducted by Gerald Robotnik in an attempt to uncover the secret to immortality. The Biolizard was a partial success; though it could quickly regenerate and was highly durable, it was confined to a life support system. It soon went out of control and killed some researchers before Gerald encapsulated it.

Fifty years later, the Biolizard resurfaced, and was defeated by Shadow while Sonic and Knuckles attempted to stop the ARK's descent. However, the Biolizard merged with the space colony and kept it on its collision course, but it was defeated by Super Sonic and Super Shadow and presumably killed.
