Pitched Battle of the Air Force II - S1.E52

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.
