Marbles

Marbles (formerly Bert Coleman) is a main character in the series and the partner of the late Leopold Archer.

Appearance
He resembles his prime self.

Personality
Bert had a bad habit of antogonizing the contestants of his game show. He even went as far as punching them and calling them names in order to humiliate them on national television. He tried his hardest to prevent Rigby from winning Expert or Liar and laughed in his face when he thought he got the last question wrong which didn’t bode well for Sanjay’s deteriorating sanity as he becomes the true Dark Mayhem. His personality was best described as coldhearted, cruel, uncaring, and sadistic. When he suffers a misfortune by getting killed, he immediately blames the nearest person he can find (Zachary), and will go great lengths to get revenge, even if it means joining the Church of Corruption. He luckily changes and gradually becomes more energetic and loyal after falling victim to Akumageddon.
