The X-Men has always boasted a deep bench of characters, including some of Marvel's most memorable heroes and villains. Even beyond iconic figures like Wolverine and Storm, the franchise has proven over the years to be an ideal showcase for a wide variety of perspectives and characters. One of the best has always been Nightcrawler, a heroic man of charm and faith despite his demonic appearance. While there was a lull period for the character in the second decade of the 21st century, the modern era of X-Men stories has reinforced this in the best ways possible.
