And it's not just Xros Heart, either, there are a huge number of Digimon from other seasons. There doesn't seem to be an Agumon, though...unless that's what those vaguely orange things to the left of Lilymon are.
GOOD GOD!!! My eyes are now freaking sore from trying to analyze who's who. I can pretty much verify a majority of those that are colored, meaning I can't verify those that are shown in silhouettes. I'll try and tag them down *goes to digimon wiki*
EDIT: Okay, tagged everyone I could identify, however, for some reason it wouldn't update tags like deckerdramon and cyberdramon when I add "char:".
