The characters of
RahXephon.
Warning: MASSIVE Spoilers abound.
Ayato Kamina
Japanese seiyū: Hiro Shimono English voice actor: Chris PattonThe protagonist of the series. An artistic youth, he finds himself drawn into a chain of events beyond his capacity to understand and through the people around him he has to find his place in the world.
- A God Am I: Happens once he's merged with the RahXephon. He does a good job of fixing things once he does, though.
- Age Appropriate Angst: Of the existential variety. He never descends beyond what's understandable, either.
- Dangerous Seventeenth Birthday
- The Determinator: "There's something I want to protect."
- Falling into the Cockpit: Subverted: Ayato has been prepared for piloting the RahXephon his entire life, he just doesn't know it until midway through the series.
- I Know Mortal Kombat: Inverted: Because he pilots the RahXephon, he's none too shabby at aerial dogfight arcade games. He's no match for Ace Pilot Elvy, though.
- Intertwined Fingers: with Haruka
- Laser-Guided Amnesia
- Likes Older Women: Averted. One of the first things he says to Haruka is that he doesn't like older women. Luckily for her, he falls in love with her just as much as he did with the teenage one.
- Lotus-Eater Machine: Vivance the Dolem traps him in one of these. He breaks out because of Reika and beats the hell out of Vivance with RahXephon's help.

- Male Gaze: As he's introduced to the cast, the camera has a tendency to fixate on the particular features of the ladies.
- Naïve Newcomer
- Nice Guy: Amazingly, considering he's the protagonist.
- Oblivious to Love
- Pro Human Transhuman
- Refusal of The Call
- Screaming Warrior
- Stranger in a Familiar Land
- Technician Versus Performer: Ayato's (artistic) ability to pilot the RahXephon is contrasted by Itsuki's failed (scientific) attempts
- Time Travel Not literal, but he feels like this after being brought out of Tokyo Jupiter, comparing himself to Urashima Taro (Japanese Rip Van Winkle and main character of the first documented story about time travel).
- Tomato in the Mirror
- What Measure Is a Non-Human?: When the Mu Phase in his blood activates, the people around him begin to have doubts about how trustworthy he really is. He proceeds to prove them all wrong by being such a decent guy
- You Are Not Alone: For the finale
Haruka Shitow
Japanese seiyū: Aya Hisakawa English voice actor: Monica RialA spunky and mysterious woman who first meets Ayato in the subways of Tokyo and promises to reveal to him the secrets of the world. Her professional competence and tough exterior hide a complex and sensitive woman.
Reika Mishima/Ixtli
Japanese seiyū: Maaya Sakamoto English voice actor: Mandy ClarkAn ethereal girl in a yellow dress who Ayato seems to recognize from somewhere. She definitely knows more than she lets on and is connected to the secrets of the
RahXephon.
Quon Kisaragi
Japanese seiyū: Houko Kuwashima English voice actor: Kira Vincent-DavisSister of Itsuki and test subject of TERRA. She knows much about the plot but will never give a straight answer about it.
Itsuki Kisaragi
Japanese seiyū: Mitsuru Miyamoto English voice actor: Jay HickmanA scientist of TERRA and brother of Quon.
- Big Brother Complex: Ironic considering he's actually Quon's son and Ayato is his older brother
- Brother-Sister Incest: Nothing explicitly overt, but his affection for Quon is a tad bit obsessive.
- Bishōnen
- Cain and Abel: He's not a total bastard despite an upbringing under Bähbem. His dynamic with Ayato is quite interesting, though not as vicious as other examples of this trope.
- Hot Scientist
- Kuudere: He's quite aloof in the first part of the series. Once his motivations are fleshed out, however...
- Ayato, I Am Your Twin Brother
- Oedipus Rex: Even though our understanding of his relationship with Quon, it still maintains the same overtone.
- Replacement Goldfish: To Haruka, in a sense. It's heavily implied that she once had a relationship with Itsuki because he looked like Ayato.
- Stoic Spectacles: By gum, he's the poster boy!
Makoto Isshiki
Japanese seiyū: Toshihiko Seki English voice actor: Illich GuardiolaAn Earth federation inspector sent to observe and inspect TERRA.
- The Casanova: He used his sexual conquests to gather information about goings on in TERRA and to gratify his own ego, with no concern for his partner's well-being.
- Cloning Blues: Eventually leading to his emotional meltdown.
- Deadpan Snarker: he'd be very funny, were he not such a condescending bastard
- Evil Albino
- Illich Guardiola
- Manipulative Bastard: Poor Nanamori
- Meaningful Name: "Isshiki" means "one color." Take a wild guess at which one. Whereas Makoto means either "truth" or "faithful" depending on how it is written. Considering his casanova personality and origin as a clone neither really apply to him. Although knowing his family, this naming was probably intentional.
- Smug Snake: Goddamn, is he ever. Characters in the series even call him "The White Snake". It runs in the family.
- Start of Darkness: He may be a callous prick as an adult, but just try and watch the episode about his childhood and not feel like he badly needs a hug. "And I wonder if that clay doll ever found its parents, in the mud?"
- Tragic Keepsake: He's kept a piece of the clay from the Dolem from his childhood that got stuck with a clump of his hair
- Tyrant Takes The Helm: When he usurps control of TERRA.
- The Unfavourite: Especially harsh when your earliest memories are fellow clones suggesting that a short life expectancy for you might be "a small mercy".
- Unwitting Pawn: To both Bähbem and Ixtli
- Villainous Breakdown: After he brings down Tokyo Jupiter and ends up inadvertently assisting the Mulian invasion plans.
- Well Done Son Guy: Ends up contributing to the aforementioned breakdown.
- With Friends Like These: With Itsuki. The scientist is Isshki's oldest and closest friend, and Isshki still treats him like shit.
- Yaoi Guys: There are hints in the early part of the series that he and Istuki had been more than just friends when were young boys.
Sayoko Nanamori
Japanese seiyū: Atsuko Tanaka English voice actor: Kelly ManisonA scientist at TERRA. Works under Itsuki, and harbors some feelings for him.
Mamoru Torigai
Japanese seiyū: Hirofumi Nojima English voice actor: Vic MignognaA friend of Ayato's from Tokyo and Asahina's boyfriend.
- Face Heel Turn
- Irony: His name means "to protect." After he's revealed to be a Jerkass, he does nothing that supports his name. In contrast, one of the most uttered lines from Ayato is that "he wants to protect" something.
- Jerk with a Heart of Gold: He acts this way a lot, especially in the first episode, but he's really just a...
- Jerkass: He's quite a condescending bastard, especially to Ayato.
- Manipulative Bastard: He REALLY likes to plays off of Ayato's guilt.
- The Rival
- Those Two Guys: Subverted, as noted above.
Hiroko Asahina
Japanese seiyū: Yumi Kakazu English voice actor: Cynthia MartinezMamoru's girlfriend and a friend of Ayato.
- Dying Declaration of Love: Which she desperately writes in a notepad as Ayato is unknowngly killing her via destroying a Dolem she's linked to. Once she dies, the lights of the nearby buildings spell it out to him.
- Fish out of Water: She becomes like this once Ayato brings her out of Tokyo Jupiter.
- Kill The Cutie
- Those Two Guys
- Tsundere: To Mamoru. We never see her 'dere' side shown to him, but she's got all the Tsun-Tsun mannerisms. And you see how she acts around Ayato...
Kim Hotal
Japanese seiyū: Fumiko Orikasa\\English voice actor: Tiffany GrantAn extremely professional member of TERRA and friend of Megumi Shitow.
Megumi Shitow
Japanese seiyū: Ayako KawasumiEnglish voice actor: Hilary HaagHaruka's younger sister.
Ernst Von Bähbem
Japanese seiyū: Iemasa Kayumi English voice actor: Ted PfisterThe enigmatic director of the Bähbem Foundation. He harbors a special interest in ancient Mayan civilizations.
- Affably Evil: He is exceedingly well-spoke and polite
- Big Bad: He certainly gives off this air
- Dirty Old Man: He seems to enjoy touching the tattoo on Quon's belly far too much. It's even worse in the movie.
- For Science!: His ultimate motivation behind making the RahXephon.
- Grand Theft Me: His means of living so long.
- Immortality Immorality: When your method of choice involves seizing control of people you've raised since birth, it definitely counts.
- Really 700 Years Old: More like millennia.
- Smug Snake: Now you see where Isshki and Helena get it from!
- Wicked Cultured: He knows much about fine art and culture, particularly Nahatual cultures. Given that he lived through most of it, this shouldn't be surprising.

She is Ayato's mother
(or better said, his aunt) , a confident and strong woman who wants only the best for her son.
