Kekkei Genkai :: Solaris
This is a bloodline trait or something.. I'm actually not really sure where it comes from, but it's been with me ever since I can remember. But it allows me to assume full dominance over the visible spectrum, and then some.
I can create optical illusions simply with a bend in light rays, no prism or anything needed. With this I can effect what my opponents see, yet not completely. It's probably better explained with actual battle experience. I've also mastered Light energy to perfection.. in healing abilities, defensive, and especially offensive.
The effects of Solaris also include a chameleon-like ability. Not to the point of invisibility, but depending on my surroundings and color affiliations, my body reacts in an odd way. I can change my dominant Element at will this way. For example, if I'm in a very snowey battlefield with cold, etc, I become an expert at Ice techniques and energy. The same would apply for fighting beside a volcano, only I'd be a master of Fire.
Now, here's the fun part.. When I combine these two techniques, light manipulation and the chameleon effect, I can become a user of anything I choose at the time. I can simply bend the light rays around the sun itself, and bathe the entire battlefield in a certain detailed, colored light concentration. Yep, through this, the battlefield takes on a certain elemental dominance, and directly effects my chameleonism.
Nifty, eh?
