Adam MacIntyre (also known as Adam the Clown) is a psychopath appearing in Dead Rising and Dead Rising: Chop Till You Drop. He was a clown performer found at the Space Rider roller coaster in Wonderland Plaza during the scoop Out of Control.
In Dead Rising 2: Off the Record, it is revealed that he has a brother named Evan MacIntyre, who is also a clown, though since the events of that game are non-canon, it is unknown if Evan actually exists.
In Dead Rising 4, Frank can dress up as Adam as part of the Capcom Heroes game mode. 
He makes his playable debut in DeadZone Crisis 2 as a DLC character
