S2·E9 Charge! Destroy the Yamato!

A Comet Empire pilot, Mazor, is captured and interrogated (mild torture). After getting his guard, Dr Sane, drunk on soy bean milk (not a difficult task, considering that it's really sake wine), he escapes. But, turned away by his own fleet, he rams the Star Force in a foolish attempt to regain his honor. Earth learns that, except for the green skin and uncontrollable eye-brows, the Comet Empire race is quite human.
