Black Knight

FIRST APPEARANCE: Uncanny X-Men Vol. 1 #194 (June 1985)

Andreas von Strucker and his twin sister Andrea were the children of Nazi supremacist Baron Wolfgang von Strucker, who saw great potential in their future. While still in-utero, the children were bio-engineered by Dr. Arnim Zola to have superpowers, using the X-Gene with each gaining the ability to fly and fire beams of concentrated plasma as long as they were in physical contact, usually accomplished by holding hands.

Now known as the Fenris Twins. Like their father, the twins are white supremacists, have great sympathy for the Nazi agenda, and strive for the Fourth Reich. The two came into conflict with the X-Men. While on safari, Storm interrupted Andreas' attempted assault on a native woman in Africa. Andrea retaliated 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 conducted acts of terrorism and finally attacked Magneto during his trial in Paris by the International Court of Justice for his crimes against humanity. The X-Men foiled their assassination attempt, but Fenris managed to escape by allowing themselves to be swept into the old city sewers.

They would later join of group of mutant millionaire supervillains known as the Upstarts, led by the telepathic Gamesmaster, until they were defeated by X-Factor. The twins tried to acquire Omega Red for the Upstarts but failed. At the end of the Upstarts competition, The twins ultimately met their match when they tried to kill Wolfsbane, the former New Mutant. Along with her new X-Factor teammates, Wolfsbane easily beat the twins. But resurfaced against X-Force.

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."

Fenris living in Madripoor met with Matsu'o Tsurayaba, the new leader of the Hand. Black Widow was sent to investigate the meeting taking place on a yacht docked at the harbor. Working with Wolverine they infiltrated the yacht and take out the gangsters, but find out they are impostors: the real meeting took place somewhere else in the meantime.

The twins traveled to the UK where they blackmailed Mesmero into using his powers for them. He took control of Excalibur to attack Fenris. Kitty Pryde was training as a cheerleader close by and left in the middle of the routine to help her team. After some debating the other girls decide to help in effect it is they and their hockey sticks that take out Fenris.

He was later invited to Krakoa to be a part of Sebastian Shaw's Hellfire Corporation.
