Alternative Versions of Wolverine - Earth X

Earth X

According to the information in the Earth X miniseries Paradise X: Heralds, the second child of the Howletts died in childbirth and the Howletts found and adopted an infant member of the Moon Clan, a bestial race which has co-existed with humanity for hundreds of thousands of years. This Clan, which is also dubbed wolf clan, were mortal enemies of the Bear Clan, to which Sabretooth belongs. Supposedly, it is this Moon Tribe child who was named James Howlett and would grow up to become Wolverine explaining the enmity between Wolverine and Sabretooth in this alternate reality.

It is also revealed that this seemingly divergent sub-species is in fact what the "true" human species would have become if not for the Celestials' intervention and genetic tampering.

In the Earth X series, Wolverine has married Jean Grey; however, they are now overweight and fit the image of a bickering couple. When the Skull attacks New York, Wolverine refuses to aid Captain America and the other heroes in fighting him. Jean, disgusted, leaves Logan, but not before claiming that she is in fact Madelyne Pryor. The two later reconcile, but have not gotten back together.
