He is Kick's older brother and one of his most common antagonists. He bullies Kick, and is left in charge of him and Brianna when their parents are out. Brad has very poor hygiene, and thinks he is popular (but this is not the case). He is presumably 14 years old as he is still taking his driver's test. He mainly tries to ruin Kick's plans and stunts, but on occasion either helps him (willingly or not) or just ignores him.
Most episodes featuring Brad have him in an antagonistic role versus Kick. They fight, usually pretty violently, though they're more destructive to their surroundings rather than each other. In "Tattler's Tale" it's revealed that both Brad and Kick enjoy their fights with each other and will go to great lengths to cover it up from their parents, suggesting they are friendly fights.
In "A Very Buttowski Mother's Day", Brad is convinced that he has "second place" in his mother's heart, and so tries to ruin Kick's present's to get 'first place'.
Brad is usually seen hanging out with his friends Horace and Pansy. They tend to act as his lackies, performing whatever task he asks of them. Why they tolerate this is as of yet unknown.
- He is very similar to Terrence from Foster's Home For Imaginary Friends, Donnie Turnbull from Robotboy, and Francis from The Fairly Oddparents; He's also similar to Vicky from the aforementioned show, in some ways.
