Marcus Jones One of Jason`s best friends. He is African-American and loves torturing his older sisters with Quincy as much as Jason does with Paige. He has a lot of sisters, and his family is wealthy.
In Camp Foxtrot he is shown to like Phoebe Wu, often comparing her to her brother, Eugene. Marcus is shown to be very smart although maybe not as smart as Jason. He loves to help Jason with his overly complicated projects like making a 19 ft tall paper machè T-rex.
In the original comics from the 1980's his appearance was a bit different. His face was longer, his hair was a bit different, his ears were drawn different, and his nose also was different.
Later as Bill Amend's drawing style changed Marcus' design got updated to mostly the design we know today but with a slightly longer face.
Finally, his face became more straightened and he became less thin.

Quincy: Marcus loves Quincy. In one strip he babysits Quincy and used him to annoy his four sisters.
Jason: Jason and Marcus are best buds. They both like geeky things, but as evident from previous comics their similarities have limits and they have stopped being friends (for a short amount of time).
Eileen: Eileen and Marcus do not interact that much but when they do it isn't in a bad way (sometimes). Eileen and Phoebe both pranked him and Jason at science camp. Now they are in a friendship club.
Phoebe: Marcus is shown to like Phoebe. He says it isn't in a like like way but they are friends.
Eugene: Marcus and Eugene don't interact as much as Jason and Eugene, Though we know that he finds him annoying. He did once try to throw a stone at him, though.
Like Jason, Marcus loves many geeky things. In the late 80's and 90's, he shared Jason's love for dinosaurs, but he too gradually became interested in Lord of the Rings, Star Wars, Star Trek, and Dungeons and Dragons.
