S1·E52 Pitched Battle of the Air Force II

With new orders from TwinMasters, HighRoller attacks First Squad. But, as the battle ensues, First Squad finds two formidable new enemies in their midst - a half-human, half-snake bounty huntress and another who appears to be half-lion, half-man. The two manage to capture First Squad and put them on a snake train headed for TwinMasters' lair.
