Mr. Invincible, Vince for short, was Merton's crude and destructive imaginary friend (described as a scalliwag by Merton) when he was a kid, but when he turned eight, Merton decided it was time to grow up, and, along with the rest of his friend's childhood playthings, Vince was locked in a toy chest in the attic.

Ten years later, Vince escaped, and tried forcing his friendship back on Merton by eliminating Tommy. Vince was stopped when Merton declared that he no longer believed in him, and he was kicked back into the toy chest. But Vince escaped again, and is currently someone else's imaginary friends.


Invulernability, object creation, eye blasts and plasma bolts.


A love for Clue and Merton not believing in him.
