MaloMyotismon

MaloMyotismon (known as BelialVamdemon in Japan) was the final villain of the Digimon 02 series. It was believed that Myotismon was killed on August 3rd but in reality, after his body was destroyed by the DigiDestined, Myotismon's disembodied data/spirit endured & went into the head of Yukio Oikawa, with the promise of bringing him to the Digital World. While inside Oikawa's body, Myotismon used 'his puppet' to create Arukenimon, Mummymon & the Control Spires. But by using Oikawa to duplicate the Dark Spore, he was able to leave his host & absorb the Dark Spores, becoming more powerful & Digivolving to MaloMyotismon.

He posed a challenging battle for the DigiDestined, who were not able to defeat him even with all the Digivolved forms of their Digimon. Again, the help of the Digivices was required to defeat him; this time it took the light from the Digivices of all the children in the world to hold him down while the Digimon attacked him with all they had to “finally” defeat Myotismon.
