I hate it when that happens, I feel ya.

Sunlight is a very valid weakness, regardless of what you may think. I understand you don't want extra weaknesses, no one does, but we're trying to help you out here. Perhaps the sun itself can cause it to shrivel up, while unnatural light (such as light from light bulbs, camera flashes, etc) has no effect? I dont know. I'm fine with zombie like tendencies (slow movement, sickly behavior, lack of energy, etc) if you want that. Can you supply us with situations in which this power would be used?

Also, be careful with the word refuse with Allen. Knowing him he'll do just that just to mess with you, and it's also a bit disrespectful.
