Digimon Adventure
When Myotismon was seemingly destroyed by Angewomon, he began to reform what remained of his body by reasborbing his Alpha Bats (who had been consuming every energy source they could find). By the evening at 6:06:06, Myotismon was resurrected as a monster with a hard-armored body and a urge to devour everything in his path. He proved to be a major challenge for the children to defeat, easily defeating MetalGreymon and WereGarurumon. But when Angemon and Angewomon were ordered to use their attacks on Tai and Matt, the energy of their attacks served to power the boys' Digivices and envoke the birth of WarGreymon and MetalGarurumon.

Yet the two newly Digivolved fighters, alone or with the other DigiDestined Digimon, were not able to defeat VenomMyotismon by themselves. It took the power of the Crests to hold VenomMyotismon down while WarGreymon and MetalGarurumon attacked the villain at his most vulnerable spot.

V-Tamer
A VenomMyotismon was with Neo Saiba during the invasion upon Lord Holy Angemon's castle. Leo tried some attacks on it before he was grabbed by MaloMyotismon's tentacles which broke when Leo Digivolved to IceLeomon and was taken out by Arcadimon. VenomMyotismon was killed by the arrival of Taichi and Zeromaru.
