[[folder:Party Members]]

!!Claude C. Kenny
-->'''Voiced by:''' Creator/YujiUeda (original) / Creator/DaisukeNamikawa (remake)
[[caption-width-right:150:His appearance in ''Second Evolution'']]

The hero of the game. Son of Ronyx Kenny and Illia Silvestri, his desire to prove himself on his own merits leads him to get too close to an alien device that teleports him to an uncharted planet. There, he saves one of the local girls with his phaser, and is mistaken for a legendary hero.

* AllMenArePerverts: During a PA with Welch in Fun City, Claude can wind up buying what is obviously an adult magazine, admiring the cover girl and her assets, ''out loud''. Welch was not surprised about it.
* BadassNormal: He's pretty ordinary, but proves to be deadly with a sword on skill alone.
* {{Bishonen}}
* ButtMonkey: Not as bad as Ashton, but several [=PAs=] in Rena's storyline serves nothing more than to make jokes at Claude's expense.
* ChickMagnet: Every female party member can end up displaying some sort of attraction to him. Even at the same time (for example, a PA with Rena and Precis has the two arguing about him).
* CrazyJealousGuy: Gets rather irrational whenever he finds out Rena's hanging out with Dias.
* {{Deuteragonist}}: If Rena is chosen as the lead.
* GoneHorriblyRight: Claude's repeated attempts to reach the Calnus with his communicator. [[spoiler:By the time they finally got to him, it was the point that Claude didn't want to leave his new friends behind.]]
* GoodOldFisticuffs: Primarily a swordsman, but he also has a couple fist techniques (some of which were also used by Illia).
* HairOfGoldHeartOfGold: Like his mother, Claude is generally friendly and well-meaning, save some early moments of dickishness when Dias is involved.
* IChooseToStay: [[spoiler:Halfway through [[DiscOneFinalDungeon Ell]], the Calnus has finally picked up Claude's communicator signal and they forcibly teleport him out of Expel. When Claude finds out from his father about the planet's approaching destruction, he asks to be sent back, but Ronyx uses his authority as admiral to put Claude in his place, believing it to be for Claude's own safety. Claude insists, using an excuse that he wants to say goodbye to his friends. Ronyx relents, but when Claude is sent back to Ell, he intentionally leaves behind his communicator so that they won't be able to track him again.]]
** One of his paired endings with [[spoiler: Rena had him living in Expel with her after the events of the game. Rena asked Claude if he regretted not going back to Earth to which he answered that he was still on Expel because he wanted to. Subsequent games make it clear that this ending is non-canon.]]
* ImagineSpot: the ladies once tried wondering where Claude got his fashion sense from, and then imagine him first in a knight's bulky armor, and after that, for some reason, in ''drag''.
* ImStandingRightHere: Flashbacks show multiple incidents where officers and other higher ranking people would discuss, while Claude was very obviously in earshot, how surely the only reason he's at the top of his class is because his professors are padding his grades to keep Ronyx happy, or how the only reason Claude is getting the opportunities he does because Ronyx is trying to prop up his service record.
* TheMatchmaker: A PA sees Claude becoming one for Leon, who has expressed an interest in all the female party members.
* NiceGuy: One of his defining characteristics is being willing to help out people he barely knows.
* ObliviousToLove: Seems generally unaware of Precis' attempts to flirt with him. If Claude said that he had no girlfriend in one PA involving him, Rena, and Precis, he would be genuinely confused when a LoveTriangle was forming between the three, much to Rena's chagrin.
* SharedFamilyQuirks: Shares traits with both his father, Ronyx, and his implied mother, Illia.
* SpellMyNameWithAnS: The original game ''Second Story'' spelled his last name as "Kenni". It wasn't until the remake ''Second Evolution'' that his last name was spelled as "Kenny".
* StepfordSmiler: A flashback shows how Claude made himself sound more enthusiastic to be cruising on a starship for the first time than he actually was, even while the other officers tried to use him to put a good word toward his father. Since no one on Expel or Nede knows his father, he can be himself.
* SwordAndSorcerer: The Sword.
* WellDoneSonGuy: Claude struggles to prove himself to get out of his father's shadow.

!!Rena Lanford
-->'''Voiced by:''' Creator/AyaHisakawa (original) / Creator/NanaMizuki (remake)
[[caption-width-right:134:Her appearance in ''Second Evolution'']]

The heroine of the game. A cheerful young girl from the village of Arlia on the underdeveloped planet, Expel. She possesses healing powers previously unknown to her world. One day, while visiting the nearby forest, she is attacked by a monster and rescued by a man wearing strange clothes and wielding a weapon that shoots a ray of light.

* AdaptationalWimp: Rena in the games has a lot of spunk for a WhiteMagicianGirl and she knows a good deal of hand to hand combat which explains why she chose knuckles as her melee weapon of choice, and eventually knows some offensive spells. In the manga adaptation, her offensive spells are gone, but at the very least, some of her hand to hand combat traits is retained. In the ''EX'' anime, Rena not only doesn't have offensive spells, she's even more inefficient in close combat.
* ClingyJealousGirl: Celine will allude to this in one Private Action by telling Claude that Rena "can be a very jealous woman." This was shown if Welch was recruited when playing as Claude. Rena was not at all happy with the idea that Claude may be flirting with other women.
** Her anime counterpart in ''EX'' was more obvious about this as she was always pissed off whenever another girl (first Celine, later Precis) was flirting with Claude.
* CombatMedic: The main healer, but she's still good with her fists and light magic. [[spoiler:By the time of ''Blue Sphere'', Rena has completed medical school and regularly undertakes missions for the Federation alongside Claude.]]
* {{Deuteragonist}}: If Claude is chosen as the lead.
* FirstGirlWins: If she has a paired ending with Claude. [[spoiler: ''Blue Sphere'' confirms that this is canon.]]
* FriendToAllLivingThings
* GeneHunting: She decided to investigate the Sorcery Globe because she thought she would discover her origins in the process.
* HappilyAdopted: Even as she wants to learn her origins, she still loves her adoptive parents.
* HeIsNotMyBoyfriend: Gets annoyed when people mistake Claude for her boyfriend. [[EveryoneCanSeeIt Her reactions don't help at all]].
* HospitalHottie: [[spoiler:Between ''The Second Story'' and ''Blue Sphere'' she attended medical school on Earth]].
* KnifeNut: In ''Blue Sphere'', Rena trades in her knuckles for knives.
* TheMedic: Healing spells were previously unknown to the people of Expel.
* MysteriousWaif
* ObliviousAdoption: Her adopted mother thought this was the case.
* OrphansPlotTrinket: Her pendant.
* PointyEars: [[spoiler: They mark her as not being a native Expellian.]]
* SpaceElves
* StrongFamilyResemblance: [[spoiler:Rena looks almost exactly like her biological mother, Dr. Rhima.]]
* SwordAndSorcerer: The Sorcerer. Type B.
* TeenGenius: [[DownplayedTrope It's not given as much attention as Leon and Precis]], but Rena is clearly very intelligent given how quickly she adapts to advanced science and technology for someone who grew up on a medieval planet, and some of her Private Actions with Bowman also centre around her going to study at the university in Linga. [[spoiler:It's discovered near the end of the game that Rena takes after her biological mother, one of the most brilliant scientists the Nedian race ever produced.]]
** [[spoiler:In ''Blue Sphere'', she apparently finished her medical education in ''less than two years'' and became a doctor.]]
* WhiteMagicianGirl
* WitchSpecies: [[spoiler:As a Nedian, she doesn't need to tattoo herself to use symbology, particularly the healing spells that are completely alien to Expel.]]
* YouGottaHaveBlueHair
* ZettaiRyouiki: Rena started the trend of doing this with ''Star Ocean'''s female leads.

!!Celine Jules
-->'''Voiced by:''' Creator/YukiKaida (original) / Creator/SakiNakajima (remake)
[[caption-width-right:350:Her appearance in ''Second Evolution'']]

A treasure hunting symbologist from the town of Marze. Claude and Rena run into her in the city of Krosse, arguing with another symbologist over a treasure map. She talks them into joining her on an expedition to a nearby cavern.

* AntiGravityClothing
* BlueBlood: Her family is aristocracy in her hometown.
* BoundAndGagged: During a {{Filler}} episode in the anime (not even in the manga, which the anime is based on) where the party got shipwrecked into an island infested with ghosts from a ghost ship, Celine ends up being captured, tied up, gagged and eventually put on an UnwillingSuspension. JustifiedTrope since she'd use her mouth for spell incantations, and [[LadyOfBlackMagic her getup]] would've been the cue for the ghosts to silence her.
* HumanAliens
* ImpossiblyCoolClothes: Her costume is standard fare as far as RPG {{black magician girl}}s go, but what the heck is up with the floating shower curtains? Said outfit is a bit less impractical in the manga, but still.
* LadyOfBlackMagic: Celine is the textbook example; a blueblood with refined tastes who specializes in powerful offensive magic.
* MsFanservice
* OptionalPartyMember: Her offer to join Claude and Rena can be turned down.
* PowerTattoo: They allow her to use symbology.
* RoyalsWhoActuallyDoSomething: [[spoiler:She becomes one of these in her special ending with the prince of Krosse. ''Blue Sphere'' confirms that this is canon.]]
* TalkingIsAFreeAction: In the anime, the surrounding tends to ignore her spell incantation, except during the Marze arc, where the enemy inflicts her with Silence in the middle of incantation.
* VerbalTic: In games, she tends to put 'darling' in her sentences.
* WhyDidItHaveToBeSnakes: Bugs. But this is only in the ''EX'' anime for Celine-exclusive comedic gags, in other versions, she has no say about bugs.
* YouGottaHaveBlueHair
* ZettaiRyouiki: She uses it to show off her [[PowerTattoo Power Tattoos]].

!!Ashton Anchors
-->'''Voiced by:''' Creator/DaisukeSakaguchi (original) / Creator/AkiraIshida (remake)
[[caption-width-right:350:His appearance in the mobile version of ''Blue Sphere'']]

A mercenary swordsman. He takes a job to hunt the two-headed dragon in the Salva mine, but is interrupted by Claude and Rena.

* {{Adorkable}}: He's a bit of a loser, though we love him for it.
* AmazonChaser: In the anime at least, Ashton's dragons like a woman who can fight (ie. Opera with a rocket launcher, who ironically [[MutuallyExclusivePartyMembers cannot join a party with Ashton around in the proper game]]). Averted with him, though, since he has more of a thing for [[TheCutie Precis]] in both the game and anime.
* {{Bishonen}}
* ButtMonkey: If anything's going wrong in a PA that isn't by the player's choice, it's gonna happen to Ashton. In the ''EX'' anime, this is taken ''way'' UpToEleven in addition of being a NoRespectGuy.
* TheChewToy: Ashton is so unlucky that he is forced to share bodies with a twin-headed dragon, and in a rare instance of averting StoryAndGameplaySegregation, he has the worst LUK stat in the game.
** One of the animations for his sprite makes it look like he was ''literally'' being nibbled on by Creepy and Weepy.
* CursedWithAwesome: Ashton has a pair of dragons grafted to his back. You can undertake a sidequest to remove them but in the end, he [[StatusQuoIsGod doesn't go through with it]] because the exorcism would kill the dragons.
* CrouchingMoronHiddenBadass: He's dorky-looking, a bit cowardly and has a weird fascination with barrels. He's also one of the most skilled physical fighters in the game.
* DreamCrushingHandicap: If he's in the party during the Lacour Tournament of Arms, he'll lament that he can't participate due to being fused with Creepy and Weepy.
* DualWielding: With both swords and [[CrazyAwesome dragons]].
* TheEeyore: He's a pretty morose guy, considering his crappy luck.
* EmpoweredBadassNormal: Ashton is a badass even before he gets two dragons grafted to his back.
* FusionDance: With the two-headed dragon. HilarityEnsues.
* GameplayAndStoryIntegration: As noted above, Ashton's Luck stat is the worst in the game.
* HeterosexualLifePartners: His PA's with Claude push this more than the other male party members, though it's entirely up to the player whether to enforce this or not.
* HighlyVisibleNinja: His moveset includes a FlashStep and DoppelgangerAttack, so he's the closest thing the party has to a ninja. However, he also has a dragon grafted to his back and ''bells'' on his cape.
* HumanAliens
* IntergenerationalFriendship: his special ending, with IllGirl Eleanor.
* MagicKnight: He's directly referred to as a Heraldic swordsman.
* MistakenForGay: In Armlock, this will happen if the player chooses the "Hearthrob" in the menu; he and Claude have to share the drink (one glass, two straws). A nearby patron seems amused.
* MutuallyExclusivePartyMembers: Him or Opera (and Ernest).
* NoRespectGuy: Nobody takes the poor guy seriously in the anime. And nobody ever notices when he does something competent.
* OptionalPartyMember
* {{Otaku}}: Ashton is an avid follower of ''barrels''.
* PeoplePuppets: Creepy and Weepy will occasionally possess Ashton and speak through him directly.
* RealMenWearPink: Rena and Chisato find a piece of jewelry among the latter's belongings, and voice their adoration for it, thinking that it might belong to a refined woman. Then they find the name inscribed on it...
* ResignedToTheCall: He comes to accept being bonded with Creepy and Weepy. While he still wants to be separated from them, he'll only do it in a way that doesn't hurt them.
* ShipTease: While he can end up with anyone, he has the distinction of getting a private action with Precis. By ''Blue Sphere'' they've become the BetaCouple.
* ThrowTheDogABone: Despite his dismal Luck stat, Ashton can equip several items that can give him a huge Luck boost. He can potentially end up with the ''highest'' Luck in the game, depending on what you give him.
* TheUnintelligible: Creepy and Weepy can only growl and snarl, although Ashton understands what they're saying and can translate for others. Subverted on those rare occasions when they speak through Ashton directly.

!!Precis F. Newman
-->'''Voiced by:''' Yuko Sumimoto (original) / Creator/RieKugimiya (remake)
[[caption-width-right:300:Her appearance in the mobile version of ''Blue Sphere'']]

A mechanically minded girl from the town of Linga. She literally runs into Claude and Rena when they arrive seeking to translate the writings found in the Krosse Cave.

* AllOfTheOtherReindeer: She and her father are outcasts in Linga due to their affinity for machines. She wants to join because Claude was one of the first people not to reject her because of it.
* BadassNormal: It's not really touched on, but all of Precis's special attacks come from her engineering genius, rather than symbology or swordsmanship.
* BecauseYouWereNiceToMe: Why she wants to join Claude.
* BunnyEarsLawyer: So hyperactive that Celine describes her as more of a tornado than a teenager. She's also a mechanical genius.
* CuteLittleFangs: In ''Second Evolution'', Precis's new "excited" artwork has these.
* GadgeteerGenius: She has developed robotic technology alongside her father on a planet with technology roughly that of 17th century Earth, [[spoiler: and needed less than two years of education on Earth to learn how to build her own space ship]]. In the encyclopedia in the [[VideoGame/StarOceanTillTheEndOfTime third game]], it's heavily implied that technology she developed modernized Expel and along with an abundance of Energy Stone, made Expel a dominant player in galactic politics.
* GenkiGirl
* HumanAliens
* JokeCharacter: Precis has several issues. Specifically:
** Her normal attack, a punch with a robotic arm, takes a fair amount of time to execute and leaves her vulnerable.
** Many of her killer moves are ineffective or have hitboxes that are difficult to line up properly.
** Her powerful killer moves require unlocking them via the Machinery skill, with obscenely low chances of success.
* LeapDay: Her birthday is February 29.
* LittleMissBadass: Precis combines this with GadgeteerGenius.
* MutuallyExclusivePartyMembers: Her or Bowman.
* OlderThanTheyLook: She doesn't really look like a 15 year old. Fixed in the remakes.
* OptionalPartyMember: Can be recruited during Private Actions before meeting Bowman.
* PowerFist
* RocketPunch: One of her Killer Moves.
* ShipTease: While she can end up with anyone, she has the distinction of having a PA with Ashton.
* TeensAreShort: She's ''tiny'' according to her official artwork, standing only to the shoulder of resident ChildProdigy Leon. The remake seems to have made her taller, though she's still petite.
** This is actually a case of the official artwork shot of the gang being way off scale; Precis has an official height of 5'1", which puts her over half a foot taller than Leon (who's 4'5"). She's still the second-shortest member of the party, but not by much (Rena and Opera both check in at 5'3", and Chisato at 5'4").
* TeenGenius
* TokenMiniMoe: Despite being only 2 years younger than Rena. Lessened considerably in the remake.
* WrenchWench: Precis can even create new weapons and killer moves for herself using the machinery talent.

!!Bowman Jeane
-->'''Voiced by:''' Creator/RyoHorikawa (original) / Creator/KeijiFujiwara (remake)
[[caption-width-right:194:His appearance in ''Second Evolution'']]

A pharmacist and close friend of the linguist, Keith. He helps Claude and Rena get the Krosse writings translated and asks to join so that he can investigate the Sorcery globe himself.

* ActionDad: In the ''Blue Sphere'' game, Nineh is pregnant and Bowman is set to become a father. This makes Precis reluctant to take Bowman on the quest to help Ernest and Opera, but Bowman insists on coming. Nineh also encourages him to go too.
* AscendedExtra: Of sorts. When you first meet him, he's working the counter of his pharmacy. If you don't recruit him, he continues running the store as an NPC and you can shop from him there. If you do recruit him, Nineh takes over running the store for the rest of the game.
* BadassLabcoat: Bowman wears and ''is'' one of these.
* ChivalrousPervert: Bowman continually ogles other women, but he will not cheat on Nineh.
* CombatMedic: Heavy on the combat.
* DeadpanSnarker: he has a good sense of humor.
* DotingParent: Became one in the time skip between ''The Second Story'' and ''Blue Sphere''.
* HappilyMarried: One of his Private Actions with Rena involves him getting her advice on what kind of ring to buy for Nineh. If he joins the party, Nineh will also take over running the pharmacy.
* HenpeckedHusband: Somewhat-one of his Private Actions involves him getting chewed out by Nineh, and then getting mad at Claude or Rena for getting him into this mess.
* HumanAliens
* JustFriends: If he ends up with a female character, their relationship is like this.
* MutuallyExclusivePartyMembers: Precis or him.
* OptionalPartyMember: Joins the party at a certain point if Precis is not already a member, but can still be turned down.

!!Opera Vectra
-->'''Voiced by:''' Yuko Nagashima (original) / Creator/AtsukoTanaka (remake)
[[caption-width-right:251:Her appearance in ''Second Evolution'']]

A noblewoman from one of the artificial moons orbiting the dead planet Tetragenesis. She is searching for her lover, Ernest Raviede, who had travelled to Expel on one of his expeditions, and ends up crashing.

* {{BFG}}: Opera's weapon. Aside from Killer Moves and flying enemies, all she does is [[PistolWhipping hit people with it]].
* ClingyJealousGirl: Some of her new Private Actions in the PSP version show her as this. She warns Rena and Welch of the dangers of pursuing Ernest, and she even ''beats Ernest up'' when she mistakenly thinks he's flirting with Precis.
* HardDrinkingPartyGirl: She sure loves her wines.
* LadyOfWar: She's pretty refined, but she can kick some ass.
%%* MsFanservice
%%* MutuallyExclusivePartyMembers: Ashton or her (and Ernest).
%%* OptionalPartyMember
* RebelliousPrincess: Opera's parents do not approve of her adventurous nature.
* RoyalsWhoActuallyDoSomething: The Vectras are the suzerain house of Tetragenesis, effectively making Opera the princess of her species. Despite this, she is an active adventurer and a powerful asset in combat.
%%* RubberForeheadAlien
* ShesGotLegs: It's why she gets offended when an arena announcer mistakes her for a man.
* StrongFamilyResemblance: One of Ernest's endings reveals that Opera has a younger sister named Opal, whose only physical difference is her hair color. Said sister also has a massive crush on Ernest.
* ThirdEye: Like all Tetrageniots. Her improved depth perception compared to other [[HumanAliens humans]] makes her a very good markswoman.
* WrenchWench: Not as obvious as Precis, but Opera is a skilled mechanic who can create new weapons and killer moves with the machinery talent.

!!Ernest Raviede
-->'''Voiced by:''' Creator/HirokiTochi (original & remake)
[[caption-width-right:186:His appearance in ''Second Evolution'']]

An archeologist from a moon of Tetragenesis. He travelled to Expel on one of his expeditions.

* AdventurerArchaeologist: One of his Private Actions in the remake is an obvious shout out to ''Franchise/IndianaJones''.
* BadassBookworm: In his ending with Noel, Ernest reveals he can't stand {{Know Nothing Know It All}}s who never do any fieldwork and just write papers. He's less than thrilled about being honored by them. Half the fun, for Ernest, is the thrill of exploring old ruins and encountering dangers.
* BadassTeacher: Teaches at a university when not on an expedition.
* CelibateHero: To a certain extent. Despite having women fall over him left and right (including more than one of the female party members), Ernest is far less interested in romance than he is in adventure and research. When Rena asks him why he doesn't return Opera's affections, Ernest replies that he isn't even certain about his own feelings. The fact that Opera is a ClingyJealousGirl doesn't help either, although his romantic rating for her is highest when he joins the party.
* ChickMagnet: In addition to gaining the affections of both Vectra sisters, Celine's starting romance rating for him is almost as high as Opera's. In a new Private Action added to the PSP version, he and Dias get ogled by a bunch of female passerby in North City. You can also have Rena gush over them, too.
* {{Expy}}: He seems to be the ''Star Ocean'' universe's response to ''Franchise/IndianaJones''. One of his Private Actions in ''Second Evolution'' has him discuss getting into chases in mine carts, among other Indy references. Claude has to explain that those are fiction and that ruins on Earth are largely the same as everywhere else, to Ernest's disappointment.
* JokeCharacter: Ernest has a long animation time on his normal attacks, and he lacks both the raw offence of Claude or Ashton and the powerful multi-hit killer moves of Opera or Chisato. However, some will get him anyway because you can steal a DiscOneNuke from his at two points.[[note]]Specifically, the Battle Armor, an armor with 500 defense, which is tied with the best armor in the Bonus Dungeon and nearly 200 points better than every armor before then.[[/note]] He does have a few good Killer Moves, notably Broken Heart, that can help him avoid the bottom tiers.
* LegendaryInTheSequel: Ernest's archeological theories are still held in high authority [[VideoGame/StarOceanTillTheEndOfTime four-hundred years later]].
* MutuallyExclusivePartyMembers: Impossible to recruit if Ashton joined the party.
* MayDecemberRomance: At least by Japanese video game standards. Assuming he eventually hooks up with one of the female party members, he'll be at ''least'' 12 years older than her.
* OptionalPartyMember: Can only join if Opera is recruited and an optional scene is viewed.
* PermaStubble
* RubberForeheadAlien
* ThirdEye: A Tetrageniot.
* WhipItGood

!!Dias Flac
-->'''Voiced by:''' Creator/RyoHorikawa (original) / Creator/TomokazuSugita (remake)
[[caption-width-right:300:His appearance in the mobile version of ''Blue Sphere'']]

Rena's childhood friend. He left Arlia after the death of his family to wander as a mercenary.

* AlwaysSomeoneBetter: Towards Claude.
* AscendedExtra: Of sorts. In the original PSX version, he only ever sleeps during Private Actions. However, in ''Second Evolution'' he actually interacts with Rena and other characters in several Private Actions.
* BadassBaritone: His voice in every versions is considerably lower than the rest of the team, and he's acknowledged as one of the biggest badasses in the party.
* BadassNormal: He's pretty ordinary, but proves to be deadly with a sword on skill alone.
* {{Bishonen}}: Though he's more mature looking than Claude and Ashton.
* ChickMagnet: Ernest noticed this and decided to have some fun in North City.
* CrutchCharacter: In Rena's scenario. Mega powerful when he's just with Rena, but Claude will surpass him once he joins for good due to Claude's Killer Moves likely to hit more. May be subverted, due to having some techniques that have high accuracy (Air Slash) and speed to interrupt things and him having some options to break the damage limit, making Dias still very viable even at the end of the game or against [[BonusBoss Gabriel Celeste or Iselia Queen]].
* CynicismCatalyst: Seeing his parents and younger sister murdered by bandits.
* DefrostingIceKing: He doesn't care for any of the other characters except for Rena (who he grew up with) and Claude (who earns his respect after the Tournament of Arms). However, he can warm up to them, especially in ''Second Evolution'' when he can interact with them in Private Actions.
* HeavySleeper: Most of the time in Private Actions, you see Dias sleeping. And that's his ''hobby'', too.
* HumanAliens
* HookedUpAfterwards: [[spoiler: with Chisato Madison in ''Blue Sphere''. They are the only ones with a special romantic ending together in the game. In the current mobile game ''Star Ocean Anamnesis'', Dias expresses that he is happy to see Chisato during her introduction event (in a rather roundabout way, but that is usual for him). While in ''Second Evolution'' they have no private actions together and their ending was changed to a non-romantic one, this ending has since been regarded as happening pre-''Blue Sphere''.]]
* IneffectualLoner
* LikeBrotherAndSister: With Rena.
* MasterSwordsman: He's a sword expert and wields his sword like an IaijutsuPractitioner.
* MutuallyExclusivePartyMembers: Him or Leon.
* OptionalPartyMember: Can only join if Rena was chosen as the main protagonist.
* TheRival: To Claude.
* ShipperOnDeck: You wouldn't believe it from someone like him, but yes he is one. Outside of Private Actions, he assures Claude that he doesn't see Rena as anything more than a little sister, and in an actual PA, he tells Rena that she is the support that someone like Claude needs.
* TheStoic
* TroubledButCute
* WorthyOpponent: His viewing Claude as this is shown by his having Gamgee give Claude a specially sharpened blade.
* YouGottaHaveBlueHair

!!Leon D. Geeste
-->'''Voiced by:''' Creator/YukiKaida (original) / Creator/YumikoKobayashi (remake)
[[caption-width-right:220:His appearance in ''Second Evolution'']]

A prodigy working with his parents in the Kingdom of Lacuer's weapon research division. Claude and Rena are enlisted to help him find the final component of the weapon that will beat back the monsters spawned by the Sorcery Globe.

* BadassBookworm: Leon is a pretty powerful mage, plus his weapon ''is'' a book.
* BadassLabcoat: Leon, being a scientist, is also this.
* BreakTheCutie: Only exclusively on Claude's scenario, when Leon found out that he's possibly the SoleSurvivor after the destruction of Lacuer's Hope, and his parents nowhere to be seen, he completely drops his InsufferableGenius manner and starts bawling like he's a kid left all alone in the world and started wishing that he should have died instead. Took Claude to [[GetAHoldOfYourselfMan slap him and telling him to place his hope somewhere else to calm him down]].
* [[CatGirl Cat Boy]]: A fellpool for no readily apparent reason. [[VideoGame/StarOceanTillTheEndOfTime The third game's]] dictionary explains this as being a result of both of Leon's parents carrying a certain recessive gene on the twelfth chromosome. A new private action in ''Second Evolution'' also addresses the issue.
* ChildMage
* DarkIsNotEvil: Leon favors dark magic, but he's pretty nice once you get past the InsufferableGenius facade.
* ImprobableWeaponUser: Books.
* InsufferableGenius: At first.
* LegendaryInTheSequel: [[VideoGame/StarOceanTillTheEndOfTime Four-hundred years later]], Leon is still famous for his work on developing Symbological Science.
* MutuallyExclusivePartyMembers: Dias or him.
* NotSoAboveItAll: Actually enjoys a Fun City skit that parodies the Sentai genre that was meant for kids his age.
* OptionalPartyMember: Only joins permanently if Claude was chosen as the main protagonist.
* PowerTattoo: Unless he keeps the symbols in his books, he has unseen tattoos that allow him to use symbology.
* PrecociousCrush: He develops one on every one of the female party members. One Private Action centres around him confessing to Claude. Claude then has to decide which girl to reveal this to, and whether he or Leon gives her the news.
* TeenGenius: Though Leon is actually a ''pre''teen example, being just 12 years old. He becomes one proper in ''Blue Sphere''. [[spoiler: In ''Blue Sphere'' and ''Till the End of Time'', it's revealed that Leon was instrumental in expanding the Federation's knowledge of symbology.]]
* TokenMiniMoe: At 12, he's the youngest of the cast. His sprite stands at half the size of everyone else.
* YouGottaHaveBlueHair

!!Noel Chandler
-->'''Voiced by:''' Creator/DaisukeSakaguchi (original) / Creator/TakahiroMizushima (remake)
[[caption-width-right:169:His appearance in ''Second Evolution'']]

A zoologist overseeing a nature reserve on Energy Nede. He helps Claude and Rena seek out the last wild psynard.

* BadassBookworm[=/=]BadassTeacher: Is a university professor.
* CrutchCharacter: In ''Blue Sphere''. He's the only healer available until Opera and Rena join much later.
* EyesAlwaysShut
* FriendToAllLivingThings: He and Rena potentially bond over this.
* JokeCharacter: Noel could be a joke character, considering he comes with spells that do less damage than those of Celine and Leon by that point, and heal less HP than Rena. The game actually lampshades his uselessness if you can get a character to randomly paint his portrait, whose flavor text describes him as having "puny muscles... hope that's okay". Add to that the fact he considers "I don't like fighting, you know!" to be a taunt. With that said, use of Bloody Armor can allow him to heal with no chance of getting damaged.
* MasterOfNone: Noel can heal, but can't even come close to matching Rena. He can use attack magic, but Celine and Leon have him beat there. He equips knuckles as his WeaponOfChoice, but all of the fighters beat him in physical combat, as does Rena.
* TheMedic: Noel serves as a combination of this and a BlackMage.
* ObliviousToLove: He has no idea that his assistant has a massive crush on him.
* OptionalPartyMember
* PointyEars
* TheRedMage
* SpaceElves
* WitchSpecies

!!Chisato Madison
-->'''Voiced by:''' Rumi Kasahara (original) / Fuyuka Ano (remake)
[[caption-width-right:130:Her appearance in ''Second Evolution'']]

A reporter for the ''Nede Chronicle'', the biggest newspaper in Energy Nede. She follows Claude and Rena around because she thinks they're the biggest story to happen in her lifetime.

* BadassNormal: She's just a skilled martial artist, in spite of the fact that all Nedians are supposed to be able to use Symbology. [[spoiler: According to ''Star Ocean Anamnesis'', there is a reason for that...]]
* DangerouslyShortSkirt: gets a MinidressOfPower makeover in ''Blue Sphere'' (with bonus ZettaiRyouiki in the mobile game adaptation) [[spoiler: which might help explain how she HookedUpAfterwards with Dias...]]
* IntrepidReporter
* OptionalPartyMember
