Like their father, the twins are white supremacists, have great sympathy for the Nazi agenda, and strive for the Fourth Reich. The Strucker twins have gone up against Storm, in which Storm interrupts Andreas' attempted assault on a native woman in Africa. Andrea retaliates for Storm's humiliation of her brother by shooting her in the head and leaving her to die.
The Strucker twins despise Magneto for his role in their father's seeming death some years after World War II. They conduct acts of terrorism and finally attack Magneto during his trial in Paris by the International Court of Justice for his crimes against humanity. The X-Men foil their assassination attempt, but Fenris manages to escape by allowing themselves to be swept into the old city sewers.
The twins later resurface as part of the Upstarts, a group of mutant millionaires who engage in a campaign of murder as part of a game organized by the mutant telepath Gamesmaster and the Hellfire Club's former Black Queen Selene. The twins tried to acquire Omega Red for the Upstarts but failed. The twins ultimately met their match, though, when they tried to kill Wolfsbane, the former New Mutant. Along with her new X-Factor teammates, Wolfsbane easily beat the twins.
The twins joined a conference of powerful criminal leaders who intended to divide up the empire left by the fallen Kingpin. 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. 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 is soon after killed by their father, who had attended the conference disguised as the assistant to Werner.
The twins resurfaced, where they were seen working with their father Baron Wolfgang Von Strucker. They fight Citizen V, though Andrea discovers that he is actually Baron Helmut Zemo. Having been decapitated by Nomad under orders of Henry Peter Gyrich, Zemo had survived when Techno, to Zemo's own surprise, transferred Zemo's mind into the comatose body of the second Citizen V, John Watkins III. Zemo quickly kills Andrea to keep her from telling anyone his secret.
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 is able to maintain the powers he shared with her as a part of Fenris.
Andrea mysterious returned, not long after Andreas had contracted to have her cloned by Arnim Zola. However, the speed at which she had been cloned concerns Thunderbolts' director Norman Osborn. Andrea accompanies Andreas and the Thunderbolts into battle against the Skrulls during the Skrull Invasion.
