well it didn't have anything to do with him being a rat man if thats what your thinking :I

I just did that because I just thought it was a cool thing to have but if your actually wondering how it works it basically like this:

he's out in the sun charging up on solar energy then he can convert the solar energy into a more pure like form thats all wispy and stuff then he could fire it out kinda like a fire ball or in a wave around him that wouldn't do as much damage but affect more people.

if its not ok I can just get rid of it :D
