The Evil Shadow Soldiers
The Arcadia nears the Horse Head Nebula. Shadows start to appear on board the Arcadia. They look like Mazone warriors. Chief Engineer Maji is convinced that one of them is Midori, his daughter. Everyone on board thinks the shadows are real until Miime shows them that they are not.
The shadows start to appear again but this time they are tangible. Captain Harlock kills one of the Mazone. He tries to kill a second one but Maji blocks the captain from getting a clear shot at the Mazone that the chief engineer believes is his daughter.
The Mazone that looks like Midori flees the ship. Maji pursues her. He catches up to her on a Mazone planet. There he learns the to accept the truth. Maji returns to the Arcadia. The Mazone attack. Maji has changed. He singlehandedly destroys the Mazone ship that attacks the Arcadia.
Thoughts
The baby Mazone in this episode were really creepy looking.
I don't understand how Maji got back to the Arcadia. I figured the Mazone were going to kill him. It was really kind of surprising how one second he was on the planet and the next he was back on the Arcadia.
