Colin. He was timid and TBH a coward at the beginning. He got teased and picked on and he did what he thought was right by tattling on Malo and Talo and Beth. He respected and looked up to Link, enough to even take the time to make a fishing rod, he wanted to be Link.
His character evolved and he grew more brave, and began to understand his father's advice. Both his mind and personality grew. He put sacrificed himself to save Beth, and apologised for pushing her.
If Colin were alive in real life, then he'd be one of the nicest and coolest little guys I'd know. Even though he wasn't too major and his character advancement felt a tiny bit rushed, I'd like to see more of him, maybe even a spin-off.
