* InnocentInnuendo: Harry overhears Reika accuse The Doctor of licking her. [[spoiler:Turns out he just licked the RahXephon]]
* IWantMyBelovedToBeHappy: This is Reika's motivation. In fact, the purpose of the RahXephon was to create a perfect life for one person.

* DeconstructedTrope: On superheroes. While there are superheroes like Superman and Spider-Man, the large majority never gained widespread attention outside of movies and comic books is because they mostly last for half a decade of activity at best before either being crippled, dying, going insane or retiring. Some of the ones that are most active have deep psychological problems, in which some were to the point of being forcefully shut down by UNIT and the FBI. Furthermore, these superheroes are [[FictionAsCoverUp heavily fictionalized and embellished]] at the behest of UNIT to protect their superpower agents. Because of this, some heroes do not have superpowers like their fictional counterparts and mostly rely on [[ScienceHero technology]], [[BadassNormal skills or raw nerve to get the job done]]. At present, many heroes are either dead (such as Superman and Captain America) or [[TakingUpTheMantle left a legacy behind]].

* RotatingProtagonist / SwitchingPOV: Jack O'Neill, Harry Dresden, and Karrin Murphy.
