Colby is a shy guy who's true personality shows to his good friends. He's an artist and a writer. He has a love for music and his family. He's pretty docile unless you hurt someone he cares for, then you're gonna get a beat down. Colby always has this wispy, faraway look in his eyes, like he wishes he was somewhere else. His imagination is always running wild with new stories and adventures.
"Look at Colby, he's so dreamy"
"Isn't Colby great at art?"
"My friend Colby is always daydreaming"
