Digimon Tamers

Gargomon manages to de-digivolve to Terriermon and Henry is left thinking about destroying real living digimon after talking to Rika. He remembers when he first got his digivice. The next day they engage in a battle with Gorillamon, a digimon from Henry's nightmare. Henry refuses to let Terriermon digivolve and he and Guilmon must face the more powerful Digimon without it. Finally, using a Card that ties Gorillamon up, Guilmon and Terriermon defeat him, but he rises again and Terriermon destroys him by firing into his cannon as he charges it, though Henry doesn't let him absorb Gorillamon's data.
