[@bluetommy2]Starfire decided not to reveal her secret just yet, and instead answered with a half truth.  "I'm a meta-human.  There are a good number of us around, and some of us can fly on our own."  The fact that he was a king, though, meant that she needed to show him proper respect to keep from angering a foreign dignitary.  "I wasn't expecting royalty to show up here, though."  She bowed slightly.  "Is there something I can help you with, your majesty?"

"Oh, I'm sorry if this offends you, sir.  I was just orbiting the sun, absorbing it's radiation, and it's plasma emissions burned off my hair and clothing.  I can go put on some clothes if you wish."
