Fenris Twins[]

Like their father, the twins are white supremacists, have great sympathy for the Nazi agenda, and strive for the Fourth Reich. Known as the Fenris Twins, the two came into conflict with the X-Men. While on safari, Storm interrupted Andreas' attempted assault on a native woman in Africa.^[7] Andrea retaliated for Storm's humiliation of her brother by shooting her in the head and leaving her to die.^[1]

The Strucker twins despise Magneto for his role in their father's seeming death some years after World War II.

Assembly of Evil[]

The twins joined the Assembly of Evil. The Assembly confronted a small contingent of Avengers who were holding a press conference regarding the "Acts of Vengeance."^[12] The Avengers defeated the Assembly with the help of Cloak and Dagger, who had only agreed to join the villains so they could foil their plans.

Crime Lords[]

The twins joined a conference of powerful criminal leaders who intended to divide up the empire left by the fallen Kingpin.^[16] Among the members of the conference were Slug, Hammerhead, Tombstone, and their sibling Werner von Strucker. The twins did not believe Werner was actually their sibling.^[17] This, and other arguments, caused the conference to degenerate into a shouting, shooting, and blasting match. Fenris attempted to kill Hammerhead but he was rescued. Their sibling was soon after killed by their father, who had attended the conference disguised as the assistant to Werner.^[18]

Fenris joined a group of villains as they battled the Canadian superhero team Alpha Flight.^[19] Still on the hunt for Magneto the team search led them into confrontation with Generation X.^[20] They found Magneto's son Quicksilver and planned to kill him in a revenge attempt against Magneto.^[21]

Zemo quickly killed Andrea to keep her from telling anyone his secret.^[4]

Clone[]

After Andrea's death, her brother became the fourth Swordsman and joined the New Thunderbolts. By tanning his sister's skin and using it as the grip on his sword, he was able to maintain the powers he shared with her as a part of Fenris.^[25] A clone of Andrea was created by Arnim Zola, commissioned by her brother. This allowed him to regain his full powers.^[26] The clone was later killed by Bullseye when it was believed that she was a Skrull.^[27]
