Wolverine #128 (1998) First Print, Cover A

Wolverine, Sabertooth, and Shadowcat are captured by the Hand and Hydra, who are working together to gain control of Madripoor. In an effort to enslave the three of them, the Hand causes key elements of their personalities to shift - Wolverine getting Shadowcat's innocence, Sabertooth getting Wolverine's sense of honor and duty, and Shadowcat getting Sabertooth's rage and violence. They have to free themselves, and Viper, Tyger Tiger, and Jessica Drew, from the Hand/Hydra while struggling to deal with this switch.
