- Ches is a child character who is somewhat hyperactive, though well behaved despite sounding rude often. He is initially very mean to PB; asking him if he's the bus driver with "the weird face." He then calls PB a loser and follows this up by calling PB a klutz. Despite this, he seems to be unaware of his apparent rudeness.
- Ches is a small, tufty haired brunet child with large hazel eyes and a striped polo shirt with a white collar. He wears some form of khaki shorts, tube socks and gym shoes.
- His mother is an unreleased character.
- Chess was the first character thus far to make a debut in an official Saga without any concept art or pre-existing information on his existence as a character. This was followed by Rodney who debuted similarly in Snowcone.
