Mummymon is Arukenimon's partner. He too was created from the DNA of Oikawa. Like Arukenimon he can disguise himself in a humon form. He pretty much just follows Arukenimon around once he shows up. He is deeply in love with Arukenimon, but she is not interested in him. He appears to rescue her when her defeat was close at hand by the Digidestined. He seems to be the only Digimon who ever actually falls in love. Later in the season he mostly serves as a comic relief. MaloMyotismon finally destroys him.
