As an antihero, Shadow has good intentions but will do whatever it takes to accomplish his goals, putting him at odds with series protagonist Sonic the Hedgehog. Shadow shares many attributes with Sonic, but is distinguished by his use of vehicles and firearms. Shadow without really trying in 06 has an IQ of 200, Sonic is consistently either as smart or smarter than him so likely 200. Cocky, superior, "edgy". Mostly emotionless, cold, sarcastic, dark humor. Deathly afraid of heights and ghosts.
