The Master Prank Caller is a character seen in the Cartoon Network animated series Regular Show. His debut and (so far) only appearance was during Prank Callers.
The Master Prank Caller is, as his name suggests, the master of prank calls. He can prank anyone at anytime by talking to them on a phone. He is a large 80's style cell phone with human arms and legs. He is later revealed to be a man in cell phone armour, although he most likely is of inhuman origin because he is capable of performing strange feats of magic - just by dialing numbers on himself, he can get anything he wants (limo, 80's clothes, etc.). He can even send prank-callers he pranks to various years in the past. He also (underneath his phone armour) vaguely resembles an alien like E.T. He first appears in Prank Callers, pranking an old lady on the internet. Mordecai and Rigby decide to be prank-callers like him and try to prank him. However, it goes wrong and they are transported to 1982 by him. They try to return to the present by sending Benson, Pops, and Skips there to help them prank the Master Prank Caller. After a long chase, they stop him and return to the present through a place filled with doors and a specific year is labeled above each. They find the door and go back home. Then he tells Mordecai and Rigby that all he wanted to do was to do prank calls like them and so they become friends and prank call Benson.
He is revived by GBF Jr., but he is sent back to Hell, killing him again.
