Chet Marcus is a main character in Best Friends Whenever. He is the twin brother/best friend of Bret Marcus, and brother of Shelby Marcus. He currently has a crush on Cyd Ripley. Chet is extremely annoying and a big troublemaker.

Chet is portrayed by Matthew Royer.


Chet (and his twin brother, Bret) cause plenty of trouble for their older sister Shelby by constantly annoying her- especially with their infatuation of her best friend, Cyd.


Chet is always dimwitted, mischievous and always a troublemaker. He is an extremely annoying brother, but Shelby and Cyd will have to deal with it. He is also a ladies man. Like his brother, he is very dimwitted when it comes to doing stuff, like playing around with random objects or electronics, as they barely know what they are doing.
