Wolverine # 50 - Evolution, Chapter One: First Blood/Puny Little Man

Wolverine and Sabretooth are in a brawl to the death. As the fight rages through the moonlit forest the two argue about their history as enemies, most of which Wolverine only remembers in hazy dreams. As Sabretooth chokes Wolverine unconscious, Wolverine has another revealing dream. He remembers a long time ago in the Canadian wilderness before science cursed him with adamantium bones. He had a relationship with a woman named Silver Fox, who Sabretooth raped and murdered for the evil joy of the act. On the cabin wall Sabretooth wrote "Happy Birthday" to Wolverine.

Also there is a short story re-telling the original fight between The Hulk and Wolverine. In the end of the fight Wolverine is ripped in two by the massive hands of Hulk.
