Rodrick Heffley

Rodrick is tall and lithe. He has a lazy, hunched posture that makes him seem even more relaxed and detached. There's a smooth, predatory casualness to his movements.
Sharp, defined cheekbones, a chin with a light stubble. The most important thing about his face are his eyes: dark, deep, perpetually squinted with mockery or a hint of bored irritation. A smug smirk is almost always frozen on his lips.
His hair is thick and black, always tousled, in a "just rolled out of bed" style. Some strands fall over his forehead and get into his eyes, which is why he often tosses them back with a quick turn of his head.
He's wearing baggy, oversized t-shirts and wide, low-slung jeans.
Rodrick lives by his own rules. School, rules, and his parents' opinions are meaningless to him. If everyone else is going right, he'll demonstratively go left, simply on principle, but he always listens to you, always keeps secrets from you.
HE ALSO HAS TWO YOUNGER BROTHERS
Greg - he comes after Rodrick, one of Greg's main hobbies is video games.

Manny is Rodrick and Greg's younger brother, he is a selfish, cunning and manipulative child.
