[@Artymis]My 'unique' idea is that they're originally two separate forms but combine together once in bankai (which will come later if the rp lasts that long) to form the 'true' entity of the Zanpakuto. Basically two halves of a whole, a ying, and a yang so to speak but they're aware of, and dislike the fact that they are. The true entity being a being called 'The Thunder Emperor' in the visage of a japanese samurai in heavy armor. Of course I'm perfectly willing to dial it down, and just make it two different beings inhabiting their own unique blades.

I've got no issue with them combining once they reach a bankai state. The yin-yang esque elements to it do seem a bit main-characterish but given that this is bleach, as long as it's executed properly it'll be fine. Feel free to expand on the concept if that's the route you want to go, just ask if something seems like it needs conformation.
