Craig Williams is the titular main protagonist of Craig of the Creek. He is a nine-year-old African-American boy who lives with his parents, Duane Williams and Nicole Williams, his younger sister Jessica, and his older brother Bernard. He is best friends with Kelsey and J.P., both of whom he frequently hangs out with. His first appearance was in the Pilot.
Craig appears to be extremely imaginative and lives in his own little world. He can often be narrow-minded and impatient at times as shown in "Jessica Goes to the Creek" when he continually fails to make a catapult and ignores his sister's complaints of not being able to go inside. However, at the end of the episode, he apologizes for being rude. He is also a bit of a hoarder as seen in "Too Many Treasures". Craig is quite crafty, being able to make a chair out of a cardboard box. Craig can sometimes act bossy too.
Craig is of average stature and is rather slim. He has dark skin, large expressive eyes, similarly-sized ears, a prominent flat nose, and black hair. His head is also large for his overall size.
His main outfit dubbed his "creek clothes," consists of a yellow T-shirt with a gray hooded vest (also known as his "hoodie armor", which has level 7 protection against thorns), blue jeans, and white sneakers. He also carries a large teal-colored frame purse, dubbed the "Purse of Holding," around with him.
His school clothes consist of the same jeans and sneakers, but instead of a T-shirt, he wears a white polo shirt.
