Origin stories are a pivotal component in superhero comics. They're the crucial backstories that shape the characters and send them on their paths. They also have a tendency to become incredibly complicated when rewrites of what happened in previous stories start stacking on top of each other. Retcons pop up in superhero comics constantly. Revelations, plot twists, new ideas, and the ability to fulfill original concepts pull stories in vast directions. Nightcrawler -- the blue-tailed teleporting X-Man -- has one of the more complicated origins in the Marvel Universe. X-Men Blue: Origins #1, written by Si Spurrier, with art by Wilton Santos and Marcus To, inks by Oren Junior, colors by Ceci De La Cruz, letters by VC's Joe Caramagna, and design by Tom Muller and Jay Bowen, sets out to bring readers the definitive Nightcrawler origin story, weaving together all the rewrites, confusion, and speculation into a single issue.
