Science Ninja Team Gatchaman, episode 31
This was a fun one; not only do we get some Joe backstory, but also an insight into the inner workings of Galactor. Though I do have to wonder why, after knocking him out, Female Berg Katze engaged an elaborate plan to dump Ken out of the train instead of just shooting him with the very gun that she'd pistol whipped him with in the first place. Oh well, our heroes have to win somehow I suppose.
