In one of the rare crossovers between Marvel and DC, Batman and Wolverine were merged into a character know as Logan Wayne, a.k.a. Dark Claw. No, really, it happened! Their origin stories were mashed together, so now it was Logan who witnessed his parents' murder as a child. However, he then moved to Canada, and it was there that a lot of Wolverine's origin took place. Dark Claw's costume obviously incorporates elements of both of these fan-favourite superheroes, including the Adamantium claws he received from Weapon X. This was one of those really weird '90s stories - don't expect to see it in a movie! Are there any more little known Batman facts? Share them down in the comments.
