So the whole Weapon X thing is a rabbit hole I didn't want to crawl down, ever. Retcons upon retcons to the point I yearn for the simplicity of time travel and alternate universes.
However, having just read Wolverine: Origins II, I am curious about just how much it flies in the face of continuity? There must have been some established reason for Wolverine and Sabretooth hating each other before 2014. Well, I know why Wolverine hates him but what made Sabretooth hate Wolverine?
Some guy on Reddit said
First time I've heard of this.The earliest instance of Sabretooth hating Wolverine as far as I can tell, was when Wolverine convinced him to join him in a kind of proto-X-Men mutant team. Sabretooth falls in love with one of the other recruits, and while fighting a foe with the ability to control minds, he possesses Sabretooth and kills the girl. Sabretooth blames Wolverine for her death, and vows that the next time Wolverine finds someone or something that makes life worth living, he will be there to take it away from him.
Is the Romulus crap still a thing?
Is there any other alternative answer besides "you killed my Jewish brother we've neve rheard of until now" and "this guy set us up fighting in Japan but we both forgot"?
I don't know why they couldn't just go with Claremont's idea. Cliche? Sure. Actually make sense? Yes.
