In Sonic Adventure 2, Shadow the Hedgehog was introduced into the Sonic the Hedgehog universe. He was said to be created as the Ultimate Life Form. However, at the end of the game, you fight the Biolizard, a giant red lizard which is said to be the prototype of the ultimate life form...

That's always baffled me for some reason. How in the world do you go from giant-ass lizard to small black hedgehog?

Who cares? Obviously SEGA didn't.

Science had strange ways of working, wouldn't you say?

BIOLIZARD.
