Some ideas I'd like to include: guns (revolver? smg?), swords, ninja, cyborg, anatomy, magic, souls.

Ideas for superpowers:
1. can use sword to ricochet incoming projectiles back at enemies
2. when an enemy in slain with his sword, their soul is captured and turned into bullets for the revolver. these bullets are metaphysical and they can penetrate most any physical material but kill souls.
3. soul sword. only does damage to souls. Is not stopped by physical material.
4. enhanced fighting ability - using integrated cyborg parts and computing

or perhaps a more ethereal character.
touch of life / redemption - when hero places hand on the head of an enemy, the enemy is enlightened and turns away from violence. however, to avoid getting killed the hero also has defensive superpowers such as shields and force fields. could be a monk type character.

Ninja Cyborg Cowboy's super power is being able to duel wield his revolver and sword, using his sword to slice / deflect incoming bullets. His sword is also used for close combat.

here we go now...

this guy has the superpower of creating and controlling metalic-crystal rock-like shards that he can use to create weapons, projectiles and armor.
