Not talking bout' his appearances in media, I'm talking about physical looks. In his first appearance, designed by Craig McCracken. He had redhead bangs, like Blossom. A red cap, red striped shirt-- 3 stripes, black in the middle. Black pants with black shoes with 3 squares in the design of the shoe. Once ressurected by Him; designed by Lauren Faust, his appearance takes a change. His bangs are now removed, instead having long spiked hair in the back. His shoes now only have 2 squares, other than that-- the rest is the exact same.
Brick is shown to have the most personality compared to all of his brothers. He is shown to continually have an ego, and even a superiority complex against his brothers (mainly Boomer). While Blossom also has an ego, Brick takes it to the extreme. His brothers get very annoyed with him. He's confident and shown to be mostly competent in his evilness (see Cartoon Network Action Pack #2), despite that - he is just as stupid as his brothers. He's the leader of the team, and shown to boss his brothers around without any regard for them. He is also especially violent towards Boomer, hitting and punching him when he says something he doesn't like. Just like his brothers, he hates anything girly and is very much a stereotypical boy in every sense of the word.
