I like this guy's design. But he's a spiteful little turd with no redeeming qualities. :D

Jonny can be best described as arrogant and snarky. He tends to look down on anyone (both figuratively AND literally because of his height) he perceives as not on his level. While he is academically gifted and values his excellent grades, he holds his social status in the highest regard. If Jonny isn't top of the pack, other kids suffer. He's quite well-to-do but not insanely rich--- upper middle class at best, but he can't resist bragging about his wealth to boost his social standing. (Little does he know his favorite target, Liam, is many times richer than he could ever hope to be!)
Jonny often tries, but fails to hold his ground, when someone with a better rep (and a better personality) than his decides to challenge him on his bullying ways. Humiliating Jonny may be a great way to stir up this spiteful coyote's ire, but it's also totally worth it.
