Stanley "Mutt" Perlmutter grew up in the hazardous waste dump known as New Jersey, breeding fighting dogs. By luck he bred a mutated 3 headed pitbullmastiff which he named Junk, Trash, and Garbage. Nature and training made the beast protective towards its master and down right deadly towards anyone else. Mutt tried to join GI Joe but his style didn't conform to anything the group did. Instead they made him part of the Renegades, a group that functions outside of the normal Joe activity and acts more like enforcers.

"Loud, unruly, terrifying to look at, and on top of that, he has the 3 headed dog drooling to chomp its teeth into you."

I decided to go with the Dreadnok look for Mutt because in the comic he hated them so much. The catcher's vest for the torso came about after looking at some old drawings I did of a thug baseball player with bullet holes all over his gear. Lastly, the leg camo is based off of the convention Dreadnoks.
