He appears as a main character in Digimon Hurricane Touchdown/Supreme Evolution! The Golden Digimentals. He is called by his In-Training form's name Gummymon by Willis in the original version.
On the way to Colorado, where Wendigomon was waiting for them, Willis and Terriermon encountered the main Adventure 02 DigiDestined; Terriermon becoming friendly with their Digimon. On their way to Colorado it was Terriermon who convinced Willis to tell the DigiDestineds about how the whole event that was Wendigomon happened. At the movies end, Kokomon's Digi-Egg reappeared near Willis and Terriermon, a sign that he would be reborn in a purified state.
In August 2010, Willis is one of the many DigiDestined to have their mind seized by Eosmon and interred within the Never World so that he can live within his memories with Terriermon and Lopmon. After Agumon (Bond of Bravery) and Gabumon (Bond of Friendship) destroy Eosmon, Willis is freed, regaining consciousness in the Real World, and playing with Terriermon and Lopmon on the beach.
