I don't really know how powerful Rayman is but what people (from CFC Community) are saying, so he could be Multi-Large Planet Level (That means he could destroy more Large Planets in one), Large Star Level (That means he could destroy Large Star) or Solar SystemLevel (That means he could destroy Solar System). How he can be so powerful like this? Because he was shown to send the Dark Teensies all way to the pig flying constellation. + Rayman in your stories are different universes, It means that Original Rayman isn't same like Rayman what you're drawing with your OC. Remember!
