passage: Juston Seyfert
As part of the "Marvel NOW!" event within the issues of "Avengers Arena", Juston Seyfert is among the young heroes who are abducted by Arcade and forced to fight for their lives in Murderworld. Others in the group include Cammi, Darkhawk, Hazmat, Mettle, Nico Minoru, Reptil, Chase Stein, X-23, Apex (Tim/Katy), Nara, Kid Briton, Red Raven, Deathlocket, Cullen Bloodstone, and Anachronism. He is attacked and the Sentinel he is working on folds around him, apparently crushing him. Juston Seyfert is later revealed to have survived, but is now paralyzed below the waist due to the injuries sustained when the Sentinel crashed. Distraught at the loss of his best friend, Juston salvages the remains of the Sentinel and creates a suit of battle armor, which he uses to attack Deathlocket. After the Runaways members Nico Minoru and Chase Stein become involved in the battle, Chase Stein transforms into the new Darkhawk and attacks Juston. The battle was aborted by Tim's technopathic powers and the group's vote for Tim/Katy's life or death. Juston was among those who voted for death. When Tim reverts to Katy, Juston is murdered by Apex who breaks his neck and then steals his Sentinel. When Deathlocket stumbles into an underground facility, Juston Seyfert's body is among the dead bodies that are seen in one of the rooms.
