Dennis Lawrence Chan
Dennis Chan(born on July 27 ) is Coop's 10 year old Asian/Canadian best friend and the main deuteragonist of the series. They used to hang out and defeat Kat together and his one of Coop's neighbors. His father's name is Henry. He lives with his high-tech family and lots of future technology. Dennis and Coop's Birthdays are one day away from each other and they always wish for the same presents. They have been friends since preschool, Dennis is the only one who belives Coop about Kat, but he also believed Coop in preschool when Coop said that pigeons flew in threw the window and drank all of Dennis's chocolate milk while he was going to the bathroom. Dennis has black hair and black eyes but unlike his father, he does not have an Asian accent. In the "missions" against Kat, Dennis is always that only one who has a plan. Others just use the "Smash and Destroy" tactic. In the last episode of Kid vs Kat, his memory is not lost
