Mienumon is a Stealth Appmon.
- Stealth Cape: Assimilates the appearance of the environment and becomes undetectable.
- Chameleon Lick: Makes what Montana-chan's tongue touches blended with the environment.
Mienumon has the appearance of a woman in a maid dress, perhaps because servants are traditionally not meant to be seen. Its left hand is a chameleon hand puppet named Montana-chan, referencing their ability to change color and its association with camouflage. It wears a blue B-2-shaped cape. Its left eye is black with the same yellow symbol as Warudamon's eyes. Like most Appmon, it has two cables on its back to allow Applink.
