Watched every episode. While he DID gain the trust of legendaries, he is no real hero, and a lot of the movies aren't canon. Ash just battles for fun, traveling around eight different regions with bandits hunting him when they could just stay in Kanto and steal from there. In Digimon, children are specifically brought in from the human world to fight whatever evil plagues the Digital World. They save lives, an entire planet, and never run from a fight. Heck, we had Mega Evolution before it was cool! Digimon can evolve and revert back to their Rookie Stages when they Digivolve, so if you don't like a form, you don't have to stay in it just because it's strong. With Pokemon (Not including Megas,) you stay in one form and evolve with levels, items, certain weather, day and night cycles, trading, and friendship levels. In Digimon, you Digivolve your partner with the power of your bond alone. And you don't just save one world, but two.
