Authors Note:
I'm having a bit of trouble, I can't think of a prank for Starfire. Also I'm not going to be updating for a while because my mom is due to have a baby any time. Also, the answer to my question was Billy Numerous first appeared in the episode 'Deception' If you don't believe me, watch it. Look for when their in combat class. When it shows the rest of the class, ( you know, not Cyborg Gixmo Jinx or Mamoth) When brother blood is talking to the people who were sitting on the stands, look on the far right-hand side, you should see him there. Guess it wasn't so easy huh?
