Fortress-2
Fortress Two - The second airship developed by Cyberbiotics, as a replacement for Fortress One, following the latter’s destruction by Demona.
Renard used his personal fortune to help build it, and, believing that the destruction of Fortress One was partly due to human incompetence, decided to have it manned purely by Cyberbiotics robots. He and Vogel went on board the maiden flight, however.
Fox decided to sabotage the maiden flight, hoping to wipe out her father and thereby secure Cyberbiotics for herself; she corrupted Vogel with a substantial bribe and had him insert a virus into the robots on board the airship, causing them to run amuck and sending Fortress Two into a direct collision course with the Cyberbiotics Tower. Fortunately, Renard and Goliath managed to prevent the disaster, with some help from a repentant Vogel.
Renard later used Fortress Two to battle Oberon during the latter’s attempt to abduct the infant Alexander. Oberon finally forced the airship down in an icestorm, although Renard and Vogel managed to land it safely in Central Park.
