Digimon Adventure Tri.
Meicoomon and Meiko join the Digidestined to solve the mystery of the infection, but Meicoomon turns herself into a much more savage form and kills Leomon.
It was revealed that Meicoomon was responsible for the cause of the infection of Digimon, and she attacks the Digidestined’s Digimon Partners, and later Dark Digivolved to Meicrackmon Vicious Mode and fights the Digidestined and their partner Digimon.
During the battle, she infected their partner Digimon and turned against Kabuterimon and attacked him, trying to infect him too, but Izzy manages to Digivolve him to MegaKabuterimon and then Digivolve into his Mega form, HerculesKabuterimon.
He was able to capture Meicoomon and cure the other Digidestined Digimon, stopping her rampage before going back to the Digital World with them so it can reboot.

She easily defeats Seraphimon, Phoenixmon, Vikemon, Rosemon, and HerculesKabuterimon, reverting to the In-Training forms, and manages to fight Omnimon and Jesmon. Raguelmon later fuses with Ophanimon Falldown Mode to become Ordinemon and flew off.
After Meiko's Digivice is unlocked, Ordinemon suffers a dissociation that enables Jesmon to extract Gatomon from Ordinemon's body. Though this would have caused Meicoomon to revert to her usual form, she remains Ordinemon permanently when Dark Gennai and King Drasil infuse her with viruses to substitute for Gatomon's data. Ordinemon is finally destroyed by Omnimon Merciful Mode, but this also unfortunately and sadly destroys Meicoomon. After bidding farewell to Meiko, Meicoomon turned into data while the fragment of Apocalymon's data ends up with Dark Gennai.
