The Nightcrawlers of the Marvel universe

저기요 to all the nightcrawler 팬 out there.
So if 당신 follow marvel closely, 당신 get to find out that there are many universes/earths in which there are different versions of our marvel heroes. This has been a part of the marvel universe since pretty much the beginning of time.

So I've always wondered, how many versions of Nightcrawler are out there? I could never pin point them all and know quite a few.
Which ones do 당신 guys know of?
Which one 또는 ones are your favorite(s)?
And why?
I would 사랑 to know and see where the conversation would go on the subject
