Tear Jerker / Space Battleship Yamato 2199

  • Erich Domel's death, motivated by his will to not make his men's deaths senseless. The Yamato surviving, thus making everything a Senseless Sacrifice, only makes it worse.
  • "A Clockwork Prisoner": Analyzer re-activates a Garmillan android soldier in order to study it. He ends up befriending the curios automata, which he names "Alter". Later, Alter curiously peeks into the mainframe of the Yamato and finds a "goddess" (who is actually Yurisha) and goes to any length to pursue it. To protect the Yamato from a hack attack, Analyzer is forced to put Alter down. The episode, as a whole, goes to great lengths to explore the question of What Measure Is a Non-Human?.
  • Celestela's death.
  • Yuki's death. Especially for how Kodai reacted: having it kept a secret to not sadden the crew and feign not suffering. Thankfully, she got better, courtesy of Mamoru Kodai activating the Cosmo Reverser just for that.
  • How the war started in the series: the Gamilan ships appeared at the edge of the system for a peaceful contact when Serizawa ordered to attack without even talking, Okita refused and was removed from command, and when Shima's father followed the order the Gamilans destroyed his ship and killed him. What's worse is that due to political necessities it was said that the Gamilans opened fire first, meaning that Serizawa got away with causing a Hopeless War, the loathing Shima and many others have for the Gamilans is completely unjustified, and the Gamilans, who are trying to force Earth into surrender, have absolutely no idea why the Terrans don't do just that and refuse the demands of surrender they send before any engagement.
