I am still working on a story for my moc, but I do know this so far. During the process of him becoming a toa he was infused with shadow, making him a corupted toa. One of his arms was transformed into a weapon. When he transfers his power through the arm he corupts whatever he touches.
Anyway, I think that this is an amazing version. I made his body even more custom. I could not get many pictures because of the bad quality.
