Collin David Cooper

Collin David Cooper is the younger brother of Chad Dylan Cooper. He is 13 years old whereas Chad is 18. Like his brother, people think he's hot and some think he's a total jerk. However, after some time, Collin is revealed to be a very kind person, if hanging out with the right people.

History
When his older brother Chad replaced Sonny in "So Random", he played Mackenzie on Mackenzie Falls. Meaning Collin has never met Sonny before. Unfortunately, he wasn't received well by the audience, and the show was canceled after it's 7th season. He quickly befriended the cast of Mackenzie Falls. His only appearance was going to be the 1-hour special explaining what happened after Sonny's departure. However, they decided not to air it. He makes a tiny appearance in the series finale saying, "So this is where I'm going to work."

Trivia

 * Collin is friends with Luke Steventon, a character from the Mighty Med universe.
