Sephiroth

A man ripped from his universe by the Organization. After his attempt to force his will upon the Lifestream, his battle with Cloud Strife was intercepted before it could reach it's climax. Still having more strenght left than the weakened Cloud, he was able to fight off the first few waves of the Organization's troops before succumbing to their out-of-universe weapons, created specifically to capture strong creatures like himself.

Sephiroth's hate for the Organization knows no bounds- even as his memories were lost thanks to their concoctions, it was the one thing he was able to cling to. He eventually forgot the reason, but he knew that they had interrupted something important between him and Cloud.

Due their strenght and multiple escape attempts, Sephiroth and Cloud were eventually placed in a sort of stasis, their bodies surrounded by a weakening substance that kept them docile, with tubes and cables attached to them to continue leeching mako and Jenova cells, experimenting with them, pumping different things inside.

Frustratingly, he feels sort of indebted to Miro, the one who led their successful escape. The loss of memories has tampered his rather... destructive desires, to an extend, but he has not fully reverted to the man he was before he lost his mind. He is angry, so angry, so hateful- but it's what keeps him going. The fury at having his memories stripped away and being used as a labrat leaves him unstable, at times, but he is wise enough not to start anything- not to damage the trust of the only one capable of helping him on his revenge against the Organization.

Even more frustratingly, perhaps, is that Miro and Cloud have decided that recovering their lost memories is their first priority- though he cannot deny that he is curious. He feels a certain... attraction to Cloud that he cannot place- a feeling that they are connected in a way he doesn't understand- yet.
