Cosmo Warrior Zero (4-Disc Series) (2001)

" In this compilation of episodes from the sci-fi anime series, the
world has been taken over by robotic immortals. Most humans have given
in and transformed themselves into robots, but Warrior Zero refuses to
relinquish his humanity. Now, he must track down legendary space
pirate and fugitive Captain Harlock. But as the war-weary Zero pursues
the rogue, the mission makes him question both himself and his
leaders. " - Netflix

Part of the Harlock Saga (or at least connected), it also references
Galaxy Express. The animation style is way dated but this is still a
blast
