First seen in J2 #8, it is learned that he is half-brother to Wild Thing (Rina Logan) and thereby the son of Wolverine in the MC2 alternate universe. It is not known who Sabreclaw's mother is. Sabreclaw looks like a short version of Sabretooth, but with Wolverine's hair color. Sabreclaw has claws, or talons, similar to Sabretooth's claws, as well. He has a healing factor and enhanced physical capabilities basically similar to Wolverine's, and a violent temper to match.
Sabreclaw was eventually recruited by The Revengers, and was a member of that group during the events of Last Planet Standing. When the entire Earth was threatened by Galactus, the Revengers stopped attacking the Avengers and began helping them, realizing that they, too, were in danger. In the new MC2 series Avengers Next, Sabreclaw, encouraged by Freebooter, petitioned for membership in the Avengers. While the Avengers have not accepted him, he has assisted them, and the introductory artwork lists him as a member of the team.
