Wilt is overly friendly and helpful; almost to a fault. He is an optimistic imaginary friend who was created by a kid named Jordan Michaels (a play on the famous basketball player Michael Jordan) who is now a famous basketball player. Wilt got his name from the legendary center Wilt Chamberlain. Wilt was created to teach Jordan how to play basketball, who was extremely short for his age and constantly lost to his older brother (as a youngster, Michael Jordan constantly lost to his brother, Larry Jordan). He wears old school styled basketball sneakers - which make his footsteps squeak like he's on a basketball court when he walks around - a red, white and blue sweatband on his wrist, and the number one on his chest like on a basketball jersey. Wilt is also known for his habit of almost constantly appologizing for no reason (usually before he speaks, he says "I'm sorry but," and sometimes asks "Is that okay?" at the end).
Wilt is a cadet in training in Sentinel Academy, but managed to show support and teamwork when their school were attacked.
