Tobias

Tobias is the actor who mainly plays Waluigi. Tobias was really positive in the start but slowly lost more and more focus and became more and more unwilling to join. After a little arguing he agreed to complete season 1 as Liquid and Waluigi. He might come back later as less important characters. Even fought he lost some interest he is really good at finding his own ways and make the character he plays to "his own", and the Waluigi impression is great I think.

Tobias has played these roles in the series:

Waluigi (Mario)

Liquid Snake (Metal Gear)

Bowser (Voice episode 1)

S.S Random Crew (himself) (Real World)
