凱文·杜蘭
The Lydecker character is written out of the series early in the second season, and Herbal Thought and Kendra Maibaum do not appear at all. Season two introduced Kevin Durand as Joshua, an experimental creature from Manticore who has distinct canine facial features. It also introduces Jensen Ackles as Alec McDowell (X5-494), who is an identical twin of Ben (X5-493), one of the original 12 escapees from Manticore, and Ashley Scott as Asha Barlow, a resistance fighter who has a romantic interest in Cale. Martin Cummins portrayed the season's main antagonist Ames White, a National Security Agency agent tasked with destroying the Manticore escapees.
