[@MagusDream] Yeah, while there's no rule against this kind of thing, we also strongly encourage you to make more original concepts. You can use their appearances, but give them a new set of skills.

Also one last thing, for the time being and to avoid clutter, you should make just one character to start with. Others have multiple due to being veteran players, and are more ensured to keep them relevant or in play.

So for now, please focus on making just one character.
