The characters of Hubspace are divided into four factions (and fifth one for those outside them).
Common Tropes to all five characters and their Deified Deathly, Hairyu
- Color-Coded for Your Convenience
- The team itself is usually grey. Each member (save Tatsumi) adds their own accent, however.
- Kakeru - Grey with red
- Delaney - Grey with yellow
- Kurumi - Grey with blue
- Tatsumi - Pure grey
- Dylan - Grey with purple
- Everyone Went to School Together: Of course at Kouzan International Academy.
- Nakama: Of course.
- Ordinary High-School Student: Rather, pre-graduate—Dylan's really the only one who deserves to stay there. He doesn't.
- Five-Man Band
- Brocast/Miiverse Screenname: Traplayer
Kakeru Wanao is an eighteen year old pre-graduate from Kouzan International Academy, with an unwaveringly relaxed disposition. He wants to become a Deathly Technology designer when he grows up, but his field can take him anywhere. He's witness to the Instigative Battle of the Conflict that happened during his graduation rehearsal, and as with any prospecting engineer, he wants to look at how it works and how all the pieces fit together. However, just as he gets deeper into the Conflict, he realizes that it's pulling Japanese society apart (and the world with it). Such events in the Conflict lead him to bear witness to Delaney's suicide in one of the Multiple Endings. He's also the holder of the Hakuryu AUSbuckle, which can enable him to transform into the Hubspace Warper Dragflare.
- Color-Coded for Your Convenience: Grey with some red accents.
- Curious as a Monkey: Ever since he was a kid, he was questioning things—in-game, he questions why such a Conflict exists.
- Driven to Suicide: His fight with Delaney after Dylan's disappearance in one of the Multiple Endings led to this, just so he could let Delaney be happy.
- The Enneagram: Type 9, unless he gets heavily invested in a problem much like the Conflict where he just wants to quell it.
- The Hero: Kakeru's the POV character for most of the game, but later on, you can switch midway.
- Ironic Name: In Japanese, Wana wo kakeru means to lay a trap. His gullibility tends to put him in the shoes of the trap's prey, however.
- Playing with Fire: Draws on the Flare-type powers and abilities of Hakuryu as Hubspace Warper Dragflare—think a white Kamen Rider Ryuki. Ironically enough, he starts off with a Bloom-type Deathly.
- Please Don't Leave Me: Happened when his parents died in a Greek demonstration that related to the inhumane of Deathlies.
- Childhood Friend Romance: In the canon ending, Kakeru proposes to Kurumi—predictably enough, she says yes.
- Vitriolic Best Buds: Kakeru being laidback is often a bane to Delaney's so-called coordination fetish.
- Wide-Eyed Idealist: Ironic for someone who'd end up controlling the Deified Deathly of the White Reality.
Delaney Terrence is yet another 18-year old pre-graduate from Kouzan, yet he wants to become a musician when he grows up. Specifically, his course takes him into Sound Engineering, but a major like that can be applied to almost anything that's remotely related to music. Delaney even formed a band with the male, same-aged members of the Engrayed and brought in two of his friends from Even Longer Island, his hometown. The band disbanded before it could release anything however, as the Conflict happened. Despite being there only to support Kakeru, he inadvertently causes Dylan to summon Deichnid to the Conflict Hubspace after the Second Battle of the Conflict. He also becomes the holder of the Kokuryu AUSbuckle, enabling him to become the Hubspace Warper Dragshock.
- Aloof Ally: Delaney was really only meant to support Kakeru despite not wanting to get involved. He thought of Kakeru's goals as well, lofty. Deconstructed in one of the Multiple Endings, though, as Kakeru ended up killing himself as soon as he realized that the Conflict's proliferation was his own fault.
- Subverted and reconstructed when it turned out that Kakeru's goals could be plausible, convincing Delaney to emotionally invest himself in the Engrayed.
- Big Applesauce: Moved to Japan after the events of the Peony Incident (otherwise known as Hubcrave) turned sour.
- Big Brother Instinct: Towards Dylan, especially after their mother died.
- Blind Obedience: What he's trying to avoid, which is why he's looking for justifiable loyalties.
- Crazy Survivalist: Can sometimes be too prepared as he's seen too many bad things happen to him during the Peony Incident.
- Color-Coded for Your Convenience: Grey with some yellow accents.
- The Enneagram: Type 6, even though his constant need to rationalize his loyalties that have nothing to do with Dylan leads to his own downfall.
- Fan Nickname: Dylan's called Delaney: the Conqueror, the Lord of the Universe, and of course, Delaney-ki.
- Heterosexual Life-Partners: With Kakeru, moreso than any other member of the Engrayed that isn't family.
- Hoist by His Own Petard: His attachment to Dylan just sends him down the drain.
- Missing Mom: Dylan and Delaney's mother left them when Dylan was about one.
- Phenotype Stereotype: Apart from the green eyes, Delaney fulfills the American version of the trope.
- Shock and Awe:Draws on the Shock-type powers and abilities of Kokuryu as Hubspace Warper Dragshock—think Kamen Rider Ryuga with electricity instead of fire. Ironically enough, he starts off with a Bloom-type Deathly.
- Brocast/Miiverse Screenname: SeyphieOfficial
Kurumi is a 18-year old girl who is of course, a Kouzan pre-graduate, and aspiring to study theater psychology to help her become an actress. Kurumi has actually starred in various Kouzan productions, be it live or recorded. She also uses her acting prowess to good use—her alter ego Seyphie Sphennsdotter, is a socialite who is the last surviving member of the Royal House of Lockeblaze. Luckily, she only takes on that identity so she could help the Engrayed out with what she calls their awesome recon bullshit. She was known for being Kakeru's first female friend (let alone his only major one). As a consequence, she's nerdy enough to call him the Fiora to his Shulk. Kurumi is also the holder of the Hairyu AUSbuckle, enabling her to become the Hubspace Warper Dragfreeze.
- Aloof Dark-Haired Girl: Apart from the one streak of blue highlights she has, she fulfills this trope.
- Break the Haughty: Realizes that she has caused Delaney to leave Dylan at home, causing him to slide to the dimension of Hubflay. This is known as a Hubspace Divergence Epiphany, in which one realizes that he or she is responsible for creating more than one universe with undesirable outcomes.
- Heroic BSoD: A natural result.
- But Not Too Foreign: Kurumi's actually half-Japanese, despite looking completely Caucasian.
- A Darker Me: Creates Seyphie Sphennsdotter to fulfill her need to enter parties and clubs, using this as a way to enter the Second Battle of the Conflict. Such publicity then cultivates her Seyphie persona into an Internet sensation.
- Deadpan Snarker: More so than anyone in the Engrayed.
- Desperately Looking for a Purpose in Life: She goes to parties just so she can help out Kakeru and the rest of the Engrayed. [[spoiler:Deconstructed when she realizes that the only way she can want something for herself that ''isn't'' Kakeru is through her Seyphie persona.
- Reconstructed when she learns how to be more assertive beyond her snark.
- An Ice Person:Draws on the Flare-type powers and abilities of Hakuryu as Hubspace Warper Dragflare—think a draconic Kamen Rider Tiger. Ironically enough, she starts off with a Flare-type Deathly.
- The Enneagram: Type 2, yet she can't learn to take care of herself unless she becomes Seyphie.
- The Smurfette Principle: One of the many traits she prides herself on as a member of the Engrayed.
- Team Mom: Known for being the most helpful, yet snarky member of the Engrayed.
- Childhood Friend Romance: In the Golden Ending, Kakeru proposes to her.
- Satellite Character: Deconstructed—she usually does almost everything in the interests of other people.
- Justified, as she feels that the only way she knows how to love her loved ones is to help them out with whatever they can, even if the means are questionable.
- Yamato Nadeshiko: Loves to cook, and make clothes—all while uploading pictures of them on her blog as Seyphie.
- This is only apppropriate for her personality, however.
- Yandere: She uses the Hairyu AUSbuckle to kill those who even try to lay a finger on Kakeru, killing him in one of the Multiple Endings as an accidental result.
- Brocast/Miiverse Screenname: Kakigoori67
- Expy: Has a striking resemblance to Alvis from Xenoblade, and by extension, chaos from Xenosaga.
- Guest-Star Party Member: You can only control him when he uses his mass produced AUSbuckle to become Yukyanne's Hubspace Warper Forme at the time of the Battle of the Second Conflict.
- Eventually becomes controllable during the route of the Golden Ending.
- Brocast/Miiverse Screenname: BigDAndLittleD
An eight year-old boy who is Delaney's younger brother and eventually, Hubspace Warper Feytall. He is known for having Asperger syndrome, even when the rest of the team is psychologically screwed. Over the course of the game, Dylan's whereabouts are unknown and the search for his body, be it alive or dead is a subplot that triggers any one of the seven Multiple Endings. Dylan is also meant to bear witness to each of the dimensional outcomes, functioning as an observer. It is only then after the events of Hubflay that Dylan comes back to his home dimension in order to save it from becoming any one of the seven other Hubspaces.
- Asperger Syndrome: Textbook example: has a hard time explaining things, sometimes speaks too fast and finds engaging in social stuff difficult.
- Voice For The Expressively Impaired: He then relies on Delaney to help him express himself better, and by extension the Engrayed—they're probably the only ones who understand him.
- Cuddle Bug: Much like his older brother. They're usually seen together with at least one arm wrapped around the other's shoulder (Delaney for Dylan)/waist (Dylan for Delaney).
- Dimensional Traveler: Took a roundtrip ticket to seven different dimensions that are portrayed in-game as seven playthroughs.
- Has Four Daddies and a New Mommy: To be exact, Dylan has, of course, his father Deven, his brother Delaney, and his friends—Kurumi, Kakeru and Tatsumi.
- Morality Pet: As lampshaded by Delaney himself:Delaney: If anything, Dylan, especially now that he's a part of the Engrayed, is pretty much the one thing keeping me on this Earth and believing in change for the better.
- This reliance leads to Delaney's suicide in one of the alternate Hubspaces when Dylan 'disappears'.
- No Celebrities Were Harmed: Deliberately designed after Ty Simpkins in his Iron Man 3 appearance.
- New Game+: Instigates each new playthrough by being subjected to watch it unravel.
- Phenotype Stereotype: Blue eyes and blonde? Sounds like a walking American stereotype, doesn't it?
- Set Right What Once Went Wrong: Dylan's main goal.
- Walking Spoiler: You Have Been Warned.
