In The Show
In his show, Grim was the Grim Reaper. He was trying to reap the soul of a hamster, but two children--Billy and Mandy--got in the way. They challenged him to a Limbo contest, so if he won, he could reap the hamster's soul but if they won, he'd have to be their "best friend" forever, although they treat him like a slave.

Physical Differences
In his show, Grim is a skeleton wearing a black and red cloak, sometimes with a scythe. In Project: Exonaut, Grim is a man with red stripes and pitch-black skin. He has a red spiral on his chest and a skull on his belt, with a Red Visor on his helmet.
