This entry is something of a backwards extrapolation, not unlike my Grandfather Twoyoungmen or Black Crow entries.

Sabretooth's background is unexplored, for the most part. We know that he's been fighting against Wolverine for years; we also know that during the 1960s or 1970s he worked with Wolverine and Maverick as a team for either the CIA, SHIELD, or SHIELD's Executive Board of Directors, performing various espionage missions. And we know that at one point Sabretooth worked in Interpol, alongside Darkhold Redeemer Sam Buchanan. We know that, despite early hints, Wolverine is not Sabretooth's son. Beyond that, not much is known about Sabretooth. But while Sabretooth is anything but a good guy, I think it at least plausible that he would have been active for the Allies during the war, and fighting the Communists after the war grants him at least nominal Hero status.

Sabretooth has an accelerated healing factor, speed, strength, claws, fangs, and superhuman viciousness.
