The Nightcrawlers of the Marvel universe

xin chào to all the nightcrawler những người hâm mộ out there.
So if bạn follow marvel closely, bạn 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 bạn guys know of?
Which one hoặc ones are your favorite(s)?
And why?
I would tình yêu to know and see where the conversation would go on the subject
