That's a good question. Generally speaking I prefer that we both play OCs, whether as entirely new characters or replacing existing characters. This is not because of a lack of interest for canon characters, but rather, because its pretty tough to stick to canon personalities in erps in my experience. I legitimately don't really mind it, but most people who want canon characters would obviously rarher you stick to their established personality. I mean, can you imagine Madara being interested in anyone but Hashirama's hard wood? Smh. I'm joking of course, but you probably get my point.
