Riddle Me This? TURBO

[CosmykTheDolfyn]

It's a very famous video game character... based on an appearance in specific game where he turned... evil.

My personality may seem paper thin,
but I am truly the gentlemen thief.
I must destroy all who I love and hate,
including my brother. Maybe this is
because I'm green with envy or maybe
I'm just brainwashed.
