• Complete Monster: Dodo is a Monster Clown whose only purpose and drive in life is to devour all he can. Dodo, initially a member of the Big Bang Zero group and one of their four elites, is also the only one to lack any redeeming quality or Freudian Excuse for his actions. What sets Dodo apart is how he devours the populations of planets, including women and children. He relishes in what he does and has no loyalty to his allies. When one of them, Heigar, was injured, Dodo took the chance to devour him. When he encountered two children on one world, he tried to eat them as well, not caring they'd be future allies. In his final battle with the heroes, he even killed the team mascot before trying to kill and devour all the other good guys as well.

    • The other maidens other than six do not appear in the story.
  • They Wasted a Perfectly Good Plot: The story initially focuses on the fact that there are 12 constellation maidens, four for each protagonist, creating a interesting Ship-to-Ship Combat setup. The plot hand waves this in favor of straight fighting.
