During the "Civil War" storyline, Battlestar allies himself with many opposed to the Superhuman Registration Act. His group includes, but are not limited to, Typeface, Gladiatrix and Solo. During a visit by reporter Sally Floyd, S.H.I.E.L.D. agents operating alongside Iron Man attack and capture many of the group. Floyd and a few others escape. Battlestar suffers a back injury during the battle and due to an oversight, does not receive proper medical care while in custody in Prison 42. He is freed by Captain America's forces and takes part in the final battle, despite his injuries.
