You can tell I've thought about this a lot.

My superhero name would be Aurora. I would have the powers of light and heat/fire, so I could shoot bursts of light from my hair and eyes and would be able to glow. The heat part would mostly be heat, not fire or lasers. My powers would have to be either heat or light constantly, so I would have to be constantly balancing between them, even if I was not fighting evil. No cape, but I would have a baby blue/marigold costume.
