HI GUYS, qq with regards to the applicability of characters - I do see Canon, original, canon AU and CRAU characters are all accepted but I wasn't clear on if that means duplicate versions from alternate universes are permissible. Specifically, if a marvel comics 616 version exists, is their MCU counterpart appable being that they have different personalities/histories/worlds?

If that's too close to the duplicate line that's totally understable, just wanted to check first. I skimmed through the questions and didn't see it already asked.
