The main digivolutions of Monmon are Apemon and Gorillamon. In the card game you are also able to make it digivolve into various other things, but you need special conditions for those.
People tend to say that digivolutions are totally random and make no sense, but they actually follow a certain pattern and are, in most cases, based on the Rookie Digimon.
