The Dark Claw Lives
Now I hear you, stop yelling! Yes there was an actual character amalgamating Batman and Wolverine.
See, I told you.
Released as part of the Amalgam Universe series of comics, created in 1996 in connection with the Marvel vs. DC production. Dark Claw was one of the many smashed together hero and villain combinations. Others included; Super-Soldier (Superman and Captain America), Spider-Boy (Spider-Man and Connor Kent/Superboy), Speed Demon (Ghost Rider and The Flash) and Iron Lantern (Green Lantern and Ironman).
I mean, some of those sound like fantastic cosplay ideas. I’d love to see a Speed Demon cosplay, that’d be so freaking cool.
