[@PKMNB0Y]Ok, I can add more detail to my sheets.

I didn't think of the Prime Directive issue.  He would realize pretty soon that there was something strange going on here, but without evidence that someone else was interfering with this Earth's cultural or technological development, he would have to lay low and try to find a way back. That would be boring, though, so I'll probably replace him.

Nightcrawler is specifically limited to teleporting only where he can see or is extremely familiar with, which in this universe means that he can only go where he can see until he settles somewhere.  If you don't like that, though, I can use a different character there too.
