Putting this in anon so people who don't know the characters as well feel more comfortable answering. Recently started getting into X-Men and found I really like Nightcrawler. Some characteristics of his remind me of Spiderman who is one of my top marvel characters of all time so it got me thinking about them fighting.
Threads I found on their abilities/how powerful they are/etc. if anyone wants to read up:
My take is morals on: Spiderman wins. Morals off: Nightcrawler wins. According to what I read, he doesn't use brutal tactics such teleporting heads/limbs off, or even generally kills, outside of alternate universe versions so in a morals on fight he would definitely lose, mainly due to being a lot weaker. Morals off: seems like he could just do a little bit of head teleporting and have it done in seconds...
Also pretty cool thing I found while looking around is that they seem to crossover a lot (with Deadpool too!) so now I need to find all those comics lmao
Now I must read this.... back on topic though. Who would win? First round: morals on (Earth-616), second: morals off (weird question for a kpop forum but I don't use any other forums so whatever, I'll ask here)
