Ultimate X-Men No. 85, Page 22

In the main Marvel continuity, the Fenris twins, Andrea and Andreas, were the terrorist children of Baron von Strucker. Their powers, created thru in-utero alterations, activated when they were in physical contact with each other. After Andrea's death, Andreas (as Swordsman of the Thunderbolts) was still able to access his abilities by touching his sister's tanned skin on the hilt of his sword. The Ultimate universe version of the Struckers sought power thru economic means and were the co-presidents of Fenris International, a global conglomerate. Their most recent plan was to incite mutant unrest, forcing governments to buy their Sentinel technology. This page shows the pair taking down Bishop. (NYCC - 2009/02)
