Space Battleship Yamato (1974)

Season 2: Episode 24

Wildstar, badly injured, reaches Desslok's command bridge. At the moment of the inevitable pistol duel, Derek faints and Nova rushes in to catch him. Seeing Derek and Nova's devotion to Earth and themselves, Desslok sees his own nobility. He laments the futility of his battle and vows never to fight (Earth) again. Echoing the advice of Captain Gideon, Desslok tells Nova the secret of how to defeat the Comet Empire from it's bottom side... and simply leaves. We learn that Treleina still lives, and rescues Venture floating dead in space. The Star Force pulls free of the wreck of Desslok's flagship and prepares what meager assortment of weaponry it has left for the final, undersea assault on the Comet Empire.
