* 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]].
* AwesomeMusic: The opening themes, "Falco" and "No Regret", definitely count.
* {{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}}.]]
* FridgeBrilliance: The talent Ueki wrote for the blank talent he won in the end of the manga is "The talent of reunion". This doesn't truly mean anything until Law of Ueki Plus and it was said that [[spoiler: the only reason Ueki still remembers and keeps his memories being erased by the sequel's BigBad is that he has the strongest hopes of reunion than anyone else]]. Anyone who even remembers this little fact would consider this a well-played ChekovsGun.
* {{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.]]
* {{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.]]
* 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.
