As much as I like the idea of having a lightning goddess, the long-haired electric knife throwing guy was too interesting.
But, with the goddess I wanted to play around with her. The idea I had was that she gathers and stores up energy inside her body. She gets energy from the storms that she can call. The energy she gathers though doesn't stay in her body for long, the energy wants to keep moving so it can 'leak' out by little spurts of lightning shooting off her skin. To keep as much energy as possible she uses a type of veil that can keep it from shooting off, and it looks very much like a plasma ball. Too much energy behind the veil can make her agitated and quick to anger, so she can release the excess at the bottom.
So, for her to attack, she has conductors around her arms that act as jewelry to direct her energy to her hands.
That's the best I could describe what I imagined, at least. She's a pretty cool lady. Maybe I'll change my mind and go back to her.
Now, for this hair-flinging man. I wanted him to be an ex-army combatant, a high-ranking official that 'short-circuited' and went nuts. From the apocalyptic future. Or something.
The idea is that people figured out how to harness the natural power of the world, world turned apocalyptic by some outside force, small official armies of people with those natural powers are created.
People with the most 'basic' (not meaning weak) natural powers are more stable than those with complex ones. Less likely to explode themselves (lack of knowing a better word, lol).
So, with this man having lightning as his power, and because before him there was no knowing of the side effects of having complex abilities, he got re-wired (I guess) and became chaotic. Went against humanity, went nuts; all that jazz.
He's got throwing knives at the end of his ridiculously long hair.. so he can throw it. And with the blade going in on itself, he can hook onto people and pull them in closer (after being shocked with electricity from his hair, of course) and do close combat.
It would probably be more effective for him to NOT use his hair, but come on. He looks great.
But, yes. I don't know how to design more futuristic army clothing. Search results end up being very similar to each other and not very pizzazz-y. We'll see.
