Someone who can make portals such as in the game portals. Or someone who is essentially a cartoon character like roadrunner

Basically.

Portal guy would be someone who can make portals in the air and can portal people around. 

The Cartoon thing is basically it in a nutshell, basically a character with all the attributes of a Tex Avery cartoon.

So whichever one you think would be better, I can play as.
