The Proud Elite: Despite being a bit of a snob sometimes, he seems to genuinely care about his friends and hates what Tiffany does. He's also a sympathetic character, even (especially?) after his transformation.
Butt Monkey: His own mother thinks he made Jorge throw him through a wall.
Ditzy Genius: Despite being The Smart Guy, he still revealed Jorge's secret to school via newspaper even though he promised not to and didn't seem to be on bad terms with him. To be fair, Tiffany made him do it.
The Lancer: Shares this role with Tony... at first.
The Smart Guy: He's shown to be doing inventions, at least in Jorge's nightmares.
