Ethan WaberThe Main Character of Universe. Lumia's older brother and member of the GUARDIANS Mobile Defense Unit.
- Bare Your Midriff: A Rare Male Example. His default outfit exposes his toned midriff.
- Idiot Hero: He really doesn't seem particularly bright in his dialogue and often charges into combat headfirst. Hyuga teases him for this, and Karen berates him.
- Right Man in the Wrong Place: Takes up arms during the first SEED attack because the only Guardian there (Leo) is paralyzed and his sister could be in danger before help arrives.
Karen ErraA female Newman and GUARDIANS instructor. She is assigned to oversee the training of Ethan and Hyuga when they enter the GUARDIANS. Strangely for a Newman, she is unable to use TECHNICs. She is actually the estranged twin sister of the Divine Maiden, and had her aptitude for TECHNICs forcefully drained by her father to increase the power of Mirei's. When Mirei is later killed, Karen is forced to assume the role of the Divine Maiden to avert a panic.
- Badass Normal: Since she is incapable of using TECHNICs, she relies on her expertise with guns and melee weapons to get through the mission.
- Dual Wielding: Her Weapon of Choice is a pair of photon daggers.
- Mini Dress Of Power: Her jacket creates this look, but she's actually wearing shorts underneath.
- She's Got Legs: Her outfit certainly emphasises her long and shapely legs.
- The Stoic: Rarely shows emotion, both in and outside of combat.
- You Gotta Have Blue Hair: Has dark blue, almost purple hair.
- Zettai Ryouiki: Grade B, though her "skirt" is actually her jacket.

A young and cocky human who joins the GUARDIANS at the same time as Ethan and forms a friendly rivalry with him. Hyuga may act like The Casanova, but he is also a devout follower of the Gurhal Faith and a genuine prodigy. He is actually the son of the president of GRM, and inherits the company during the events of Ambition.
He becomes infected by the SEED Virus during his work as a member of the GUARDIANS, and despite taking suppressants he eventually mutates into a SEED-Form. He is saved and reverts back to his human form, but sometime between the events of Episode 3 and Portable 2 he- along with many other humans who were exposed to the SEED Virus- transforms into a Dewman.
- The Casanova: Brags to Ethan that *his* partner is a girl and immediately tries to flirt with Karen when she's introduced.
- Painful Transformation: When he mutates into a SEED-Form.
- Peek-a-Bangs: In Portable 2 Infinity.
- The Rival: To Ethan.
- Took a Level in Badass: His transformation into a Dewman in Portable 2 Infinity. If not for the Artificial Stupidity, he'd be classified as a Game-Breaker because of the nature of his Infinite Blast.
Maya ShidowA female Newman, and Karen's adoptive sister as well as a researcher with the GUARDIANS Research and Development Department.
- D-Cup Distress: A brief cutscene in Portable reveals that she doesn't really like having large breasts.
Lucaim NavAn male CAST and headmaster of the GUARDIANS Academy.
- Dirty Old Man: Loves pinching the butts of his female students ... for training purposes, no less!
- Double Entendre: Just about everything Nav says in combat can be taken the wrong way.
- Old Master: Despite being a CAST, he resembles an old man.
Leogini Santosa BerafortA male Beast. Member of the GUARDIAN Mobile Defense Unit.
Tonnio RhimaA Hot-Blooded male Beastling. Like all beastlings, Tonnio looks like he's not older than twelve, but he's old enough to be your father. During the events of Universe, Ambitions, and Portable Tonnio is part of the GUARDIANS. In Portable 2 and Portable 2 Infinity Tonnio has since left the GUARDIANS in three years since the events of ''Ambitions'' and married Liina. He now works with Liina as a pair of mercenaries.
- Battle Couple: with Liina in Portable 2.
- The Big Guy: Despite being small, he has plenty of brute force at his disposal (especially during his Nanoblast.)
A more calm and collected female Beastling. Like all Beastlings, Liina looks like she's not older than twelve, but she's old enough to be your mother. During the events of Universe, Ambitions, and Portable Liina is part of the Tyler Family - as the second in command to Alfort Tylor. In Portable 2 and Portable 2 Infinity Liina has since left the Tylor Family in three years since the events of ''Ambitions'' and married Tonnio. She now works with Tonnio as a pair of mercenaries.
- Battle Couple: with Tonnio in Portable 2.
- Pregnant Badass: In one of the sidequests we learn that Linna is several weeks pregnant with Tonnio's baby. Yet she was able to kick the native creatures' butts for the first half of the quest - then her morning sickness caught up with her.
LouA CAST in the GUARDIANS Intelligence Unit. Lou's specialties include data gathering and analysis, hacking, and blowing stuff to smithereens with her SUV weapons. Lou is a special CAST in that she is the only CAST to have multiple bodies that all share the same mind - an ability previously only belonging to Copy-CASTs.
- Machine Monotone: Lou always speaks in same monotone voice no matter what situations she is in. This, coupled with her Stoic status.
- Me's a Crowd: As noted above. There's even a mission where you help one Lou rescue another. It's a good chance that you never work with the same Lou twice.
- More Dakka: Her SUV weapon.
- The Stoic: Purposely limits the emotions she shows and feels as they impair her work. Though she learns to open up a bit more - when doing so won't impair her duties.
- Robot Girl: Well she is a CAST.
Lumia WaberEthan Waber's little sister. She joins the GUARDIANS in Episode 3 as a new recruit, and by the events of Portable 2 has become one of their most elite agents. Although the older Lumia is highly-skilled and focused, she tends to dismiss the help of others and work alone.
- Action Girl: By Portable 2.
- Apocalypse Maiden: In Episode 3, she is used by the bad guys as a vessel of negative emotion, which would catalyse the resurrection of Dark Falz.
- Big Damn Heroes: How she is re-introduced in Portable 2.
- Defrosting Ice Queen: She is quite cold towards Little Wing in Portable 2, sometimes to the detriment of the mission. Her Character Development has her mellow out and learn to rely on others more.
- Distressed Damsel: For a lot of Episode 3.
- SergeantRock/SternTeacher: Emilia says she has become this in record time as a Guardians instructor.
- Sibling Rivalry: One of the contributing factors to why she tries so damn hard in Portable 2. She has a lot to live up to, being the little sister of the famous hero that basically saved the entire Gurhal System.
- Special Guest: She makes a special appearance in Phantasy Star Online 2 in her Portable incarnation as a guest star, where she shares a few non-canon bonus cutscenes with Vivienne.
- Took a Level in Badass: By Portable 2.
Laia MartinezA senior Beast instructor within the GUARDIANS. Laia is renowned for her ruthless training regimen, to the point where merely graduating from her tutelage is considered an achievement in itself. She is the adopted daughter of GUARDIANS President Obel Dallgun, and feels that she has to prove herself worthy of both her professional position and of being his daughter. When Dallgun is killed during the events of Ambition, Laia inherits his position as leader of the GUARDIANS, although she is reluctant to do so at first.
- Black-and-White Morality: Has trouble trusting Ethan due to her zero-tolerance attitude toward criminals. Justified because the crime he is accused of is an attempt to assassinate President Dallgun, who has the added bonus of being her father.
VivienneA new Super Prototype CAST with unprecedented emotional processing capabilities. She is assigned to be the partner of the Player Character in Phantasy Star Portable, who is tasked with shaping her emotional development. Vivienne is generally quite friendly and dedicated, though she comes off as naive at times. She is actually a Copy-CAST of Helga Neumann, who uses the unwitting Vivienne as a mole within the GUARDIANS, with everything she sees and hears fed back to Helga.
- Little Bit Beastly: Her antennae resemble a pair of rabbit ears.
- Robot Girl: Well she is a CAST. Even though that technically she's a Copy-CAST the trope still applies
- Shadow Archetype: To Helga, as the personality of a Copy-CAST is a copy of the original creator. This means that Vivienne shows how Helga used to be, before her mind was corrupted by the SEED.
- Special Guest: She makes a special appearance alongside Lumia Waber in Phantasy Star Online 2, starring in a few non-canon bonus cutscenes.
Player CharacterThe main character of Portable 2 (Episode 1 in Infinity) and Episode 2 in Portable 2 Infinity. A former mercenary, who after a turn of events, joins Little Wing and forms a team with Emilia. Unknowingly, their arrival would change and motivate the lives of people they meet later on, for the better.
- The Ace: They get recognized as being one of the top members in Little Wing, during the events of Episode 1.
- Badass Crew: S/he along with his or her Five-Man Band.
- Brains and Brawn: They are the Brawn and Emilia is the Brains.
- Eternal Hero: S/he becomes this for the Portable games, if data is imported from Portable to Portable 2 or Portable to Portable 2 Infinity.
- Five-Man Band: Originally the team is consisted of the Player and Emilia. Even though some members only join temporarily, if they were to be categorized they fit the following roles:
- A Friend in Need: In Episode 2, they decide to help Nagisa in her quest to find the Dark Falz Fragments. This eventually leads on them becoming good friends.
- A Hero to His Hometown: After the events of Episode 1, s/he is considered as Hero by the members of Little Wing and Nagisa and Wynarl. During dialogue most people call s/he a hero.
- Heroic Mime: Their dialogue in cut-scenes is player-input through dialogue options. Aside from that they don't seem to speak much.
- Heroic Sacrifice: Near the beginning, when s/he and Emilia were celebrating a victory over the Svaltia, it turns out that the Svaltia was not dead. Before it can strike Emilia, the player pushes her out of the way and takes the blow for her. Later on it is revealed that they died, but thanks to Mika, she was able to repair their damaged flesh and resurrected them.
- Living Emotional Crutch:
- The player becomes this to Emilia. This allows the Player to get her to open up to him/her while also encouraging her to try new things. Because of their time together with Emilia, whenever she needs any type of support they are the ones to help and encourage her.
- He also becomes this to Nagisa over the course of Episode 2 in Infinity.
- Nice Guy: Most dialogue options, show that he or she is a good person and very friendly towards others.
- Old Hero, New Pals: If you import the same character from Portable to Portable 2. Your previous partner was Vivienne, in Portable 2, you have Emilia, Yut and others.
- Platonic Life-Partners: With Emilia. Even though at the beginning the player doesn't know her as long as, Kraz or Chealsea, it's for certain that Emilia and the Player have the closest relationship by the end of Episode 1. There is also a bit of ship tease between the two, in both Episode 1 and 2, although most of the time it's just platonic. There are a lot of moments that show how close they are. Some examples include:
- On their first day at Little Wing, after showing you your room, she goes to SLEEP IN YOUR BED.
- Emilia has entered the main character's room, several times without their permission and in their absence.
- At the beginning of Chapter 9, when Emilia is to go to the Guardians HQ, to use Tenma, she asks the player to accompany her. One of the choices is "Can't you find someone else", to which she replies that she can't and she does not want to find someone else, because doesn't want anyone else besides, the main character to accompany her.
- Before the final dungeon, she admits the player is the only person she can be honest about her feelings and how talking to them makes her worries go away;
- Protagonist Without a Past: We never find out the origins of the Player Character. By Portable 2 they are known, to be a mercenary. Averted if save data from Portable is imported, where they were members of the Guardian's Investigation force and Vivienne's partner, but get discharged.
- Purely Aesthetic Gender: Stat-wise there are some differences, where males seem to have around 5% more HP, ATK, DEF and EVA, whereas females have around 5% more ACC, TEC and MND. They also have a larger PP pool and thus regenerate more PP per second than males. There are other differences that will be different depending on the race you choose. Episode 1 does not have any differences in dialogue no matter the gender, however in Episode 2 some of the dialogue will be different depending on the gender you choose.
- Supporting Protagonist: Played with a bit in Episode 1. While the player character is definitely The Hero regardless, in the game's story, most of the focus is on Emilia, with the player taking on something of a Deuteragonist role. In Episode 2, the player takes the role of The Protagonist with Nagisa taking over as Deuteragonist.

A lazy and unmotivated girl who works as a mercenary for Little Wing, mainly because her boss is also her reluctant legal guardian. She suffers from a critical lack of ambition, and the story of Portable 2 focuses on how she regains her drive after becoming the partner of the Player Character and being possessed by the Ancient known as Mika.
- Brilliant, but Lazy: She really hates working to the point of irritating Kraz before Player Character joins Little Wing. If she cares to use her brain for once, she can figures out things even faster than party members in average.
- Happily Adopted: By the change of her name into Emilia Muehler by the end of Portable 2, it's implied that this happens.
- Iconic Item: Combat-wise, it's her Magic Staff Clarita Visas.
- Out-of-Context Eavesdropping: She overhears Kraz and others discussing about forbidding Emilia to accept any mission, which results in him running away to do an investigation on her own. What she doesn't hear is that they do this to keep Emilia from harm.
- Powers via Possession: When Mika "takes over", her combat power increases.
- Sharing a Body: She and Mika shares the same body.
- Wetware CPU: She was used by the GUARDIANS as the core of an experimental Wetware CPU. This ended up cultivating her antisocial behaviour, as the scientists treated her as a part instead of a person.
Kraz MuehlerSecond in Command Of Little Wing and Emilia's legal guardian.
- Guns Akimbo: He uses this among his other Weapon of Choice. He's also seen wearing this during the game's opening and cutscenes.
- Inter Species Romance: His relationship as a Beastling with Ursula, a Newman.
Yut Jun YunkersA young warrior in-training of the Kasch tribe the party fought during a mission with Emilia, Liina and Tonnio to find Kasch Tribe village.
- Big Brother Worship: He looks up to his dead older brother who was a warrior in his tribe.
- Non-Human Humanoid Hybrid: He's a Half-Beast and Half-Newman.
- Not Afraid to Die: Majority of his personality is his reckless nature and a mixture of this and Death Seeker. This comes from his brother who said that a warrior could be strong when they "touched death" which he misinterpret as actively seeking for death in battle. In actuality, what his brother meant was a sort of adrenaline rush when someone wanted to live.
- Trademark Favorite Food: Pudding. It's one of the first foods he eats outside his village.
Ursula LaurentA Female Newman and owner of Little Wing.
- Interspecies Romance: Her reltionship with Kraz, a Beatman.
- Whip It Good: Her Weapon of Choice among others. This is also a weapon she's seen with during game's opening.
Chelsea EnchanteA female CAST and receptionist of Little Wing.
- Drill Sergeant Nasty: She used to be an instructor in AMF. It's also not-so-subtly hinted during a sidequest that she's infamous for being very strict.
- Flower in Her Hair: She has a prsumably artifical red and black flowers on the right side of her head.
- Gratuitous French: She occasionally throws a French word or two.
- Improbable Weapon User: Her SUV is Champagne.
- Long-Range Fighter: While other CAST team members usually have short range weapons among others in her arsenal, hers are excusively long-range.
- Ridiculously Human Robots: She looks really, really human-like, possibly even more than majority of CASTs in the game. Even her "boobs" slightly jiggle during cutsenes.
- She's Got Legs: Our first sight on her at the game's beginning is her exposed leg. Granted we as the player are supposed to be awake recently from an injury, but still...
MikaAn Ancient who co-inhabits Emilia's body.
- Hair of Gold, Heart of Gold: She's definitely on the good guy's side.
- Royal Harem: She used to be part of Kumhan's harem in the past.

A character introduced in Expansion Pack game Portable 2 Infinity. Nagisa is a "Deuman", a new race of mutated humans who have gained supernatural powers from exposure to the SEED virus. She is a cold and determined young woman who is searching for a series of mysterious fragments.
- Cry Cute: In the True Ending, after leaving Little Wing, thinking there was nothing there for someone who assaulted its members, she wanders Gurhal, attempting to prove that Wainal was a liar. She comes across the player character, Emilia and their friends, however, and realizing that he did give her the one thing she wanted most on her birthday, she starts crying tears of joy.
- Defrosting Ice Queen: Overtime, Nagisa eventually learns to relax, especially around her newfound friends... Which makes it all the more heartbreaking when you have to face her after she thrashes everyone. See Suicide by Cop.
- Disappears into Light: Does this in the Normal Ending.
- Eyepatch of Power: Like with most Dumans, this acts as a power limiter.
- Flower in Her Hair: Has an all blue floral decoration which seems to be made up of a rose and holly leaves.
- Genius Ditz: She's a combat expert, having years of experience alone to work with, but to say Nagisa lacks common sense would be such a horrible understatement. It makes for some hilarious moments, though.
- Example 1: Yut has to find himself a bride before coming back to his village. He comes to Nagisa, wondering if she knows where he can find that bride. She recalls the word, but misremembers its meaning, telling the Kasch boy that a bride is a rival. The player character even comes across this, and it isn't until after she misdefines it to Yut that she sees them.Nagisa: ...? What's wrong, <Player>? Why do you look as if you are about to laugh?
- Example 2: The obligatory beach scene includes her being utterly oblivious to why everyone's gawking at her and her swimsuit until the player character explains what's going on.
- Example 1: Yut has to find himself a bride before coming back to his village. He comes to Nagisa, wondering if she knows where he can find that bride. She recalls the word, but misremembers its meaning, telling the Kasch boy that a bride is a rival. The player character even comes across this, and it isn't until after she misdefines it to Yut that she sees them.
- I Just Want to Have Friends: One of the things she's revealed to want in the True Ending in a flashback. She gets her wish.
- Impossibly Cool Weapon: Her greatsword, which (taking a cue from the Lyrical Nanoha series) can expend bullets to increase its power.
- Ineffectual Loner: Her character arc boils down to working past this, as she's fought alone for most of her life. It takes a lot of help from the player character and their friends, and maybe a little bit of Wainal's handiwork, for her to get there.
- Laser-Guided Amnesia: Absorbing the Dark Falz fragments does this to her, on top of being generally unpleasant to her body and mind. She's forgotten a lot of things, but if you reach the True Ending, a post-game dialogue shows that everything's coming back to her, bit by bit.
- Red Eyes, Take Warning: If it's covered by a patch, you're safe. If she removes it and her other eye turns red, though...
- Sealed Evil in a Can: She's the can for Dark Falz.
- Sharing a Body: She and an Ancient named Wainal shares the same body.
- Suicide by Cop: Attempts to have the player character kill her to avoid unleashing Dark Falz on the Gurhal system. Twice. The first time has the potential to go through, but if you refuse to fight back, she tries this again on the Holy Ark Crowley. This one fails outright, as by that point the player character is determined to bring her back alive.

Renvolt MagashiA CAST who leads the mysterious Endrum Collective, a group that wishes to use the SEED Crisis to monopolise the A-Photon technology discovered in the Relic Sites. He is actually a Copy-CAST of Karl F. Howzer, created to stir dissent and advance the goals of the Illuminus. In The Magashi Plan, the player cooperates with a "defective" clone of him. This same clone goes on to be the vessel for Dark Falz in Subplot 4 of Episode 3, Chapter 8.
- Back from the Dead: He is killed during the game, but is revived by the SEED to act as an incarnation of Dulk Fakis. After that, a second copy is defeated and repaired by the GUARDIANS, mellowing him out a bit.
- Flaming Laser Blades: His weapon of choice is the Two-Headed Ragnus, a pair of jagged burning Sabers. He can even cast Foie using them!
- Large Ham: Boy is he ever. He inherited this trait from Howzer, the human he is a Copy-CAST of.
- Playing with Fire: Again, he uses burning Sabers and uses them to cast Foie.
- The Rival: To Ethan.
- Worthy Opponent: The "defective" Magashi clone views the player character as this, especially when he has to fight them (as Dark Falz) in Subplot 4 of the Episode 3 finale.
Karl F. HowzerThe shadowy leader of the human supremacy group, the Illuminus. He seeks to use the SEED Crisis as an opportunity to advance his own agenda and commit genocide on the non-human races. It is later revealed that the Illuminus was a front for Howzer's true goal: to find a vessel for Dark Falz and unleash them upon the Gurhal system.
- Large Ham: You can only hear his voice when you fight him, but he crams as much scenery as possible into his mouth in those few brief moments.
- Light Is Not Good: He wears a bright white outfit and leads an extremist group
- Klingon Promotion: Got his position as head of the Illuminus by assassinating the previous one.
- Power Floats: When he faces the player directly, he is floating in the air.
- Rubber Man: Downplayed. He occasionally attacks you by punching you with a stretchable fist.
Helga NeumannA mysterious terrorist linked to a number of SEED attacks. She bears the name and appearance of a scientist who disappeared over twenty years ago, but she does not seem to have aged a day. She is actually a clone of the original Helga Newmann made from SEED cells. The SEED cells have corrupted her original personality, bending her will towards that of the Hive Mind SEED. There are also hundreds of these clones, essentially making her immortal.
- Enigmatic Minion
- One-Winged Angel: Has two such transformations, although the second is into Dulk Fakis.
- Undying Loyalty: To Howzer. It helps that an alternate ending for A Brighter Day reveals that she loves him.

The main antagonist of Portable 2. Shizuru is a charismatic young man who is at the forefront of subspace research. He is seeking the "Codexes", which would open the way to Maghara and allow the Ancients to carry out their master plan.

- Final Boss: For multiple games in the Universe series.

- One-Winged Angel
- Wave-Motion Gun: Can fire one out of its chest.
