Well, Guilmon has fought a lot of mean Digimon before, like the Devas! Those were Ultimate level Digimon, too, so they were really strong. Guilmon could also talk about biomerging. That's how me and Takato reach the Mega level, and that's the strongest level ever!

[He emphasizes this strength by stretching really tall and slashing his claws... before losing his balance and falling on his rump. Oops.]

Um... I'd talk about cards, but I don't know if your Digivices work with them. Takato would sometimes slash cards through his Digivice to make me stronger in fights!
