Rex

Rex is Gary's beloved robotic dog and faithful companion. Created around six years ago, Rex is incredibly loyal and always willing to help Gary out in a jam. Gary apparently has the ability to communicate with Rex, despite the fact that he only speaks in barks and growls. Shades is also apparently quite fond of Rex, and likes to play with him while Gary is away.
