I'm interested in this. I do feel like having to write both halves of a partnership in RPs like this often leads to people having less time to interact with the other players; it becomes kind of insular, since you need to develop not just two characters but also a relationship between them which takes up a lot of writing effort. So a Digimon RP where you get to focus on one character is appealing.

I'd be down to play the human side of a partnership, but I could also play a wild Digimon if need be. I never watched Frontier, so I wouldn't know what to do with a Spirit Wielder.

I wouldn't mind playing a villainous wild Digimon either, I haven't played a villain for a while, but only if there are enough other players that it won't leave the heroic side feeling thin.
