[@Saarebas] Well, I had two idea's for characters, one only works in a future setting, the other is a witch that takes on the appearance of a 13 year old girl, because she hates the fact that all heroines have to be tall, busty bombshells. The Women of the Justice League having a "Supermodels only" rule and they refused to let her in unless she took on the form of an adult. She promptly flipped Red Tornado the bird before telling him that she liked him better when he was a big fat lady.

Ok, it wasn't actually like that, but she likes to say it like that.

But, yeah, she is essentially a fun-loving witch that loves children and always loves to take on their form. But, is about 500+ years old.
