I'd like my Fairy Godmother to grant me three superpowers
1. Shapeshifting. I can instantly transform my appearance to look like someone else! Famous, ordinary or even a creature such as a horse or a bird! I believe Maya from Space 1999 was able to do this and she was called a Metamorph!
2. Time travel. I can hop back in time and witness famous events. I would be invisible though so as not to come to any harm.
3. Invisibility. I could have such fun with this! I'd visit my vile cheating ex and sneak in ad move things around or slam doors so he thought there was a ghost or blame his tart so they argue! Mwha ha ha!
Or if that's a bit over the top, I'd choose
1. To have a beautiful singing voice. I'm tone deaf and sound dreadful.
2. To be beautiful. Shallow I know!
3. Greyhound racing to be abolished and no more animal cruelty or abuse worldwide ever again.
