[quote=@Havoccultist] I think I'll play a pure antagonist in this RP, as I'm not sure I have it in me to play both sides of the conflict at the moment. At least not to the degree of making two completely fleshed out versions of the same character. Maybe my character's alternate self could serve as a MacGuffin for a subplot or two before they get axed or something if we really want to include them. Another question I had though concerned the setting. Does it have to be Earth or a version of it? Or, given that it's a multiverse now, could our characters technically come from anywhere provided it's not a fandom/pre-existing fictional setting? [/quote] Yeah, or if we ever get to a point in the plot where your antagonist character is defeated or killed, you could then bring in a good version of that character from a different timeline who then inherits their Quantum Shard or something. As to your other question, it's totally fine to come from places other than Earth or Earths that are radically different. For instance, there could be timelines where humans or humanoid life developed on other planets, and timelines where non-human humanoids developed on Earth. There could be Earths similar to the movie Bright, where elves, orcs, fairies, etc exist in modern society. What did you have in mind?
