Notes: Originally referred to (and even named on the cover of The Incredible Hulk Vol. 2 #126) as Night-Crawler. Yes, the character was the original Night-Crawler of the Marvel Universe. However, after a certain mutant made his debut in Giant Size X-Men #1, the character has almost exclusively referred to himself as Dark-Crawler, most likely a conscious move on all the writer's parts that have handled him to avoid confusion. Night-Crawler is still listed as an aliases in The Official Handbook of the Marvel Universe A to Z (2008) - HC vol. 03.
