Brad is similar to Mac's brother Terrence from "Foster's Home for Imaginary Friends"; from their behavior towards their little brother, to very minor things like same hair and eye coloring and so fourth. Brad is also 2 years older then Terrence.
It's possible that Brad likes the color pink. In one episode the helmet he uses on his bike is pink, and in another he wears pink themed clothing when he forms a band in "Garage Banned".
Brad is stronger than Kick but in some episodes, Kick has shown the strength to beat Brad in a fight. Despite a lack in muscles, Brad can throw, pick up, carry, and hold him with ease.
As seen in "Pinch Sitter", Brad's favorite drink is apple juice.
