Well, I have no idea what you're talking about if it relates directly to digimon. If you're not, then I still don't have a 'favorite' iteration, and generally think of vampires as kinda 'meh', given their basically human appearance, and recent overhyping.
For you- just as an example, look up Myotismon. Or, Vamdemon, as the Japanese name is, cause that's more detailed. Well, we don't have the four characters yet, yeah?
Well, we may never have four character sets. Anyways, I kinda get it, but why aren't we against a level 6 digimon? Meh, maybe there are others that are at that level, this is just, like, the first boss, or something.
Well, how about if it takes until Friday, we just play with three character sets instead of four, maybe? I dunno, it's your RP. I just don't want to see it sink.
If I'm going to write a character that will be in the majority of the story, I'm going to write them well. And use the system for them. Because I'm running everything else though, I only feel comfortable using one character.
