Nanimon

Nanimon is an Invader Digimon that is good at boxing. He is from another dimension. The reason why he invaded the Digital World is unknown. In the dimension, he was given the nickname "Oyaji", and was kept as a digital pet. He used to have a tyrannical nature but he evolved into a more softer nature due to his love of drink after his invasion (still unidentified as to how he invaded and why he was invading) was a success. He soon adjusted to the survival of the fittest within the Digital World, and soon turned out to be a tough fighter, even if his abilities are unknown. He is loosely based off a Tamagotchi character named Oyajitchi. His name is a play in the Japanese question "nani?" meaning "what?", in allusion to his random, unexplainable behavior, as well as odd physique. In his video game roles, he's been a hard to find character that's always changing location.

Digimon Adventure
DemiDevimon hired a Nanimon to train a Sukamon, Chuumon, some Numemon and some Vegiemon for Myotismon's army. Agumon and Palmon went undercover as PunkAgumon and ReggaePalmon to find a way for the DigiDestined to get into Myotismon's castle. The trainees were aware that Nanimon's head becomes full of bubbles when he drinks pop (in the Japanese version, it was alcohol) so a Numemon sneaked into a tower without him noticing and sent the bottles of pop out the window by parachute. When 5 of the DigiDestined's Digimon Digivolved to their Champion Forms, he and his students were scared off before Gatomon summoned the Devidramon to battle them.
