Haha, no way do I want Xorn in the UU. I think he's just a bad omen.
Whenever he'd mentioned in a book my skin crawls, I still don't get it, and have no real will to guess what the truth may be, Xorn was a mistake from the offing.
Well, I found Xorn to be a really odd character to pit into the X-Men and, after he turned into Mangeto, an even weirder one. He came back as that Xorn's twin or whatever (What a great explanation, Chuck) and he seems to be a lot more powerful than he originally put on. I wouldn't mind having him around if, like E, said he was changed from all of this mess into something UU suitable.
ARGH! This is why people leave comics. Why the **** is the one company that is espousing an ultimate line and a overt agenda to streamlining continuity still producing books that **** around with continuity?! Continuity is only a problem if you start ****ing with it. Let people tell their stories and then leave. Don't start writing stories about other writer's stories! ****ing hell, why do they keep making the same goddam mistakes?!
As Ice said, if they had stuck with Xorn being something that Magneto made up, everything works PERFECTLY. Nothing needs to be fixed. But with all the crap afterward, it has seriously ruined the character.
The ironic thing is that by fixing (read: Ultimizing) him, they won't really be improving anything, unless they once again made him something Magneto made up. If you HAVE to make him a real person, make it so that Magneto imprisoned him and impersonated him, let him free, and LEAVE IT. But even then that totally screws up what was cool about him.
