My quirk is Solid Lunar Lightning... I found the idea of the solid lightning part on a fanfiction on Quotev.com.
It gives me the ability to take the shape of anything and make lightning and solidify it. The only one that can break any lightning that I solidify is All Might.
I added a few more things to my quirk (I have just one quirk FYI). I can turn into a silver-colored-fur Spirit Wolf.
Since I train my quirk a lot, I managed to grow black and white angel wings that let me fly!
