Together, Larry Hama and Mark Texeira really bring out Sabretooth in this four part series.
This story takes place after Wolverine #64. Sabretooth was trapped inside a plant pod by the Psi Borg, a member of the original Weapon X program who created all the memory implants. (Explanined in the Wolverine comics.)
Sabretooth now has a telepathic sidekick that cools Sabretooth's mental pain. Birdy befriends him and the Tribune has Sabretooth captured and is forced to kill Mystique.
This a really good title to pick up if you like Wolverine or X-Men or even Sabretooth. The story has lots of action and humor.
