You can only have magical powers if the person you're roleplaying with wants to believe it as well.
Otherwise you're just a nutcase.
Reminds me of the time a Wilde used it's mind powers to stop Jakes ship. Jake stopped his ship thinking "Oh this Wilde actually wants to RP." But the Wilde opened fire the second it got into range.
IMO it's better to stick with just normal human characters. It is possible to achieve unique while remaining ordinary.
You don't need magical powers or fur, you don't need to be an ace pilot or the 12 year old admiral of an order battleship with a cambridge university degree, or the princess of some gallic royal family.
