Thief

I drew my OC Thrifty. Okay description time.

Thrify is the son of Flippy and Shifty. He is an only child and he wears glasses. he likes his glasses but he takes them off when he goes looting so the glare can't be seen.

He doesn't like people much, since he shy. He has never been the first to introduce himself. He met Sweetie in the park when he was little.

Thrifty doesn't like to put much effort into things so instead he uses his brains to trick others into doing his dirty work. When he was young he tricked Sweetie into using her super powers to help him steal from Lumpy's house and not get caught.

He doesn't show any signs of having a flip side, except for one instance, and he pushed Sweetie off of a bridge.

Sweetie and Thrifty are a couple, best friends, and arch enemies. He doesn't fall for her until she's forbidden to ever see him again by Splendid and he breaks her out.

So yeah. Thrifty.
The background made me think of the open ended relationships he has with most people, never any strong ties.

Thrifty (c) me!

(edit) correction he has a big brother named Bloody he was never told about
