Digimon Tamers: Battle of Adventurers
An Archelomon is among the Digimon in VP Labs when Takato and his cousin Kai Urazoe venture there to rescue the kidnapped Minami Uehara. It lunged at them as they emerged from the lab's tide pool, but Growlmon easily destroyed it in mid-air. Shortly thereafter, another Archelomon is in the void between Earth and the Digital World. However, it is quickly destroyed by Omnimon.
