Digimon Adventure 02
Shortly after the Christmas of 2002, wild Digimon appeared all over the world. Tortomon and his partner Lou helped escort the escaped Digimon around America to a rendezvous point in New York City so that they could be return them to the Digital World. When they arrived alongside Maria, Centarumon, Steve, and Frigimon, they see a Cherrymon being escorted by Phil had gone crazy and began attacking the Christmas tree at Rockefeller Center, and was being fought off by Flarerizamon, ExVeemon, Lillymon, and Seadramon. The newly-arrived Digimon are able to weaken Cherrymon long enough for Flarerizamon and the Japanese Digimon to knock the tree Digimon unconscious.
Tortomon later makes an appearance during the final battle against MaloMyotismon, and lends his energy to the DigiDestined to defeat the demon lord Digimon.
