Space Battleship Yamato

The Star Force is nearly out of Telezart's system when the Comet Empire reaches it. Treleina finally makes contact with Prince Zordar, challenging his philosophy of subjugation. Ironically, Zordar's reasons for his campaign do reflect a common state in humanity -- complacancy and laziness. Nevertheless, Treleina rejects his rationale, and turns her entire planet into anti-matter, causing a magnificent explosion into which the Comet Empire plunges at full speed. The Empire eventually emerges from the explosion severely damaged and unable to continue its course to Earth for some time. No trace of Treleina or Telezart is left. Venture is emotionally crushed. Treleina is presumable dead.
