* AngstWhatAngst: if Ueki's team loses the third round, they'll die. Nobody cares about this little fact. [[BigLippedAlligatorMoment Everybody just seems to forget about that lottery in the second round]].
* {{Badass Decay}}: Initially a member of the {{Quirky Miniboss Squad}}, Rinko gradually begins to suffer from this more and more as the series continues and she is outmatched more and more often. [[spoiler:At least until they hit her {{Berserk Button}}.]]
* CompleteMonster: The corrupt doctor Kuroiwa in the first episode, who had no qualms [[CarFu about running two cars over three restrained people]] (including a small boy).
** Karlpaccho, not only is he lecherous, but [[spoiler: but injected Sano's God candidate with a boy sucking parasite in order to force him to join the Robert's Ten, and later mocks him when he sacrifices himself]].
* CrowningMusicOfAwesome: The anime soundtrack seems to be loaded with several completely awesome songs. Case in point: ''"Battle of Abilities"''. Someone just pulled a thoroughly epic turnaround on their opponent? There's a song to go with it.
* {{Foe Yay}}: With Robert. Hey, if you say you'll do anything to gain his trust which includes licking his shoe...
** Also between him and Marline, Sano and Anon.
** Robert has this with Kosuke and Sano (behind the scenes apparently). Concerning Kosuke, he wasn't pleased that Kosuke [[spoiler: saved his life during battle]] and when the match was put on a halt, he started [[spoiler: considering to join forces with him. Too bad Margaret wouldn't let him.]]
* GameBreaker: Mori's power. [[AwesomeButImpractical The only thing that prevents it from being one is the]] "[[AssKickingPose Goodie Two-Shoes Pose]]" [[AwesomeButImpractical requirement]].
** [[spoiler: Also, Ueki's [[AntiMagic Level 2 power]].]]
* {{Ho Yay}}: Ueki with Sano. He'll go to extreme lengths to protect him, it's always Kosuke that has to go save him and Kosuke literally snaps at the person who hurt him.
** An example of this is shown in the semi final match is the best example. Sano was knocked out of the battle in 2 minutes time and Kosuke snapped at his opponent. [[FridgeLogic Funny how you don't see Kosuke yelling at the opponent Mori was fighting in the previous match despite the fact she was at a disadvantage.]]
* NightmareFuel:
** Anon can take the form and powers of any being... after he ''swallows them whole.''
** Also, his introduction is him trying to do really horrifying things while being completely unaware of why it's wrong.
** Also, Robert Haydn. [[spoiler:He was swallowed by Anon.]]
* TheScrappy: Several fans seem to find Mori Ai terribly annoying.
** It has to do with constantly complaining, her annoying voice and the fact she doesn't do much even when she has her powers. Also the fact that she's the only one on her team to not lose an individual fight even without powers.
* TheWoobie: Rinko, Robert later flat out states that she's the most easily manipulated of the Robert's Ten, and she breaks down.
** Robert Haydn himself could be considered this once you learn his back story.
