Nanimon is an obtainable partner digimon and you can also recruit one to the city in this game. You need to find Nanimon in 5 locations to recruit him. You only have to talk to him though, not battling is necessary, and Nanimon increases the amount of items you can hold at once as well.
Nanimon can be obtained as a partner from any rookie Digimon. For a Digimon to become Nanimon, they must be scolded until their happiness and discipline bars drop to 0; after that, the player must keep constantly scolding the Digimon until it evolves.
Nanimon appears as a post-game tamer the player can face on various locations; the player has to beat him in Junk City before being able to see him at other locations.
