This is more of a description than a biography. Chuckinstuf isn’t introduced until The L Squad: Phase Two where he plays an important role. It may be necessary, in the near to distant future, to have some background on him.
Chuckinstuf is a Xellwamian from the planet Xellwam. Xellwam is a planet of fur. All Xellwamians are ridiculously hairy. Even the plant life on Xellwam is hairy instead of leafy. The Xellwamian who invented the Xellwamian vacuum is the richest and most famous Xellwamian in Xellwamian history. His name is Largsnof Suckitup.
Chuckinstuf is slightly larger than the average Refugee Alien Defender. Under his thick coat of redish brown fur, he has eight tentacles that extend from and retract into his belly area. They are excellent for hand-to-tentacle combat or hugging Dave, the insurance salesman. Also hiding under that plethora of fur is a pair of wings. Chuckinstuf can soar like an ostrich or a chicken. What? They don’t fly? How about a penguin? No. What kind of bizarre birds do you have on Earth? He flies like the Guianan cock-of-the-rock or the critically endangered California condor. If you think bird poop is bad, you don’t want to be under Chuckinstuf when he’s flying.
As a member of the R.A.D., Captain Grek assigned Chuckinstuf to the J Squad as its captain. He has an aversion to blasters and prefers throwing things. His weapons of choice include flash grenades, stun grenades, or dropping monster doodies as he’s flying.
