During the fight against Calmaramon, their partners' refusal to give up causes Togemon, Birdramon, Kabuterimon and Ikkakumon to digivolve into Lillymon, Garudamon, MegaKabuterimon and Zudomon. Lillymon, Garudamon and MegaKabuterimon destroy Calmaramon, allowing Zudomon to destroy the obelisk that she's protecting.
After the other DigiDestined return to the Digital World, Zudomon suddenly appears to save Tai Kamiya and Agumon from two attacking Seadramon, hitting them with his hammer and forcing them to retreat.

After Ikkakumon has no luck against Olegmon, he digivolves into Zudomon who has slightly more luck before he is eventually defeated. Joe and Zudomon's determination to protect their friends causes Zudomon to digivole into Vikemon.

While facing the Mega Argomon, Zudomon digivolves into Vikemon, passing through Argomon as a streak of light in mid-digivolution along with the other partner Digimon, destroying Argomon. As WarGreymon, MetalGarurumon, Seraphimon and Ophanimon battle the Giant Negamon inside of its orb, Vikemon and the other Megas attack the tentacles coming out of Negamon's orb, destroying several. However, the Giant Negamon fuses with its orb to become Abbadomon who reverts all of the Digimon but WarGreymon, MetalGarurumon, Seraphimon and Ophanimon back into their Rookie forms and destroys the physical forms of those Digimon and their partners.
After the hope from people all over the world restores their physical forms, Gomamon and the others digivolve back into their Mega forms and channel the power generated by everyone's hope to Seraphimon and Ophanimon for them to use to cause WarGreymon and MetalGarurumon to DNA Digivolve into Omnimon. After noticing that the fight within the orb is causing Abbadomon to lag, Vikemon and the other Megas resume their attacks on Abbadomon, hoping that it will also slow down Abbadomon Core within the orb. Vikemon destroys more of Abbadomon's tentacles before everyone's determination causes Omnimon to Mode Change into Omegamon Alter-S and destroy Abbadomon.
In the Digivice: Virtual Pet, Zudomon can digivolve to Vikemon.
