I.. What am I looking at here?
j/k: These are Dark Claw and Hyena from Amalgam Comics, where Marvel and DC combined their favourite superheroes and supervillians. In this case Wolverine + Batman and Sabretooth + Joker. Other famous names include Iron Lantern and Thorion of the new Asgods. This is an actual thing. Take Logan Wayne's backstory:
“At the age of 5, after witnessing his parents’ murder at the hands of an armed robber, Logan Wayne was sent to live with his uncle in Alberta, Canada. His uncle was a member of the Royal Canadian Mounted Police, and was ambushed and murdered by poachers a short time after his arrival in Canada.”
