Haylee, Ordan and the Tau Family along with any entities that live inside Haylee's head.
Tau Family
Erra Tau
- Even Evil Has Loved Ones: Genuinely loves Natah and clearly uncomfortable with being the Manipulative Bastard in order to keep her under control.
- Evil Cannot Comprehend Good: He was unwilling to consider that his sister may have chosen to become the Lotus willingly, which allowed him to be strung along by Ballas.
- Redemption Equals Affliction: Badly burnt by the Sun and forced into a coma after he chooses to help Haylee save his sister.
- Well-Intentioned Extremist: To the Sentients, believing Ballas's lies promising prosperity for his people, and working under the assumption that Natah was brainwashed into staying with the Tenno. Zigzagged as he manipulates Natah into sacrificing her lifeforce to fuel Praghasa as well as leaving his father to rot under the seas of Uranus, but under the reasoning that it is all for his people. Too bad he was a Horrible Judge of Character.
Haylee
Haylee
Quirk: Unnamed Warframe transformation and Tenno Power based quirk.
Haylee in U.A, Hero, and Casual Outfit
The last surviving Tenno and inheritor of The Man in the Wall's power.- Came Back Wrong:
- Whatever happened to her during the Zariman 10-0 incident changed her into something not human.
- Her new quirk that allows her to transform into a Warframe, complete with Painful Transformation.
- Desperately Craves Affection: Ordan notes that Haylee is a bit touch-starved and will hug Natah and himself whenever they return, and sometimes sneaking into their rooms at night to sleep at the foot of their beds.
- Drama-Preserving Handicap: Loses access to her mods, arcanes, gear, and weapons. That doesn't make her Warframe powers any less dangerous, just decreases the number of skills she can use before recharging. The real handicap is holding back on lethal attacks to be a hero.
- Fatal Flaw: Wrath. Not to the extent of Katsuki, but she her first response to confrontation is hostility in most situations, as shown with the Vestige of the Wall and Izuku.
- Hypocrite: Despite her insistence that she doesn't want to care about people, she genuinely cares about Natah and Ordan, and did care about Teshin. Toshinori calls her out on this.
- Lady Swearsalot: Frequently swears, especially when she's angered.
- Painful Transformation: Transforming into her Warframe form is described as extremely painful, especially if she is only transforming part of her body.
- Safety in Indifference: Haylee's reason for being The Loner. Also the reason why she tries to keep her emotions suppressed because its easier than controlling them. Despite her initial insistence on this she is a Hypocrite and wants to have friends and a normal life. She starts to get over this after Toshinori helps her realize that the new universe is far safer and she deserves to be happy.
- Trademark Favorite Food: She develops a fondness for chocolate after being given some by Izuku for the first time.
Hunhow Tau
Father of Natah and Erra and the Sentient Destroyer of Worlds.
- Appearance Angst: He does not pleased with his new human form, although it is more out of disgust that he shares the species with humanity.
- Adaptation Species Change: Becomes human upon arrival to the new universe, much to his dismay and disgust.
- Adaptational Wimp: Justified in the case of his initial defeat. When he first arrived he was weakened by centuries of being buried under the depths of Uranus, along with the strain of interdimensional travel. All Might is able to take him down in a single punch in that state. He is then starved, electrocuted, and subjected to Midnight's quirk repeatedly. It is noted by Nezu that were Hunhow to reach full strength, he would be far more powerful than All Might.
- Via Drama-Preserving Handicap, as Natah makes him promise to stand down and live amongst humanity.
- Even Evil Has Loved Ones: Natah and Erra, despite their less-than-ideal relationship.
- Fantastic Racism: Hates the Orokin, and by extension humanity with a burning passion. This includes the humans of the MHA universe despite being entirely detached from the Old War.
- Person of Mass Destruction: Still possesses all of his destructive power compacted into his new human form.
Natah Tau
- Actually Pretty Funny: Agrees when Ordan points out how weird their lives have gotten when she gets embarrassed over wanting to experience something as mundane as changing her hairstyle without shapeshifting.
- O.O.C. Is Serious Business: When Natah drops her stoicism in a serious situation you know something is wrong.
- Technically Naked Shapeshifter: Uses her mimic powers to create self-healing clothing for training use. Lampshaded by Ordan.
Ordan Karris
Ordan in casual and hero outfits.
Ordan Karris
Quirk: Calcification
- The Atoner: Feels immense guilt for the actions he committed under the Orokin as the Beast of Bones.
- Back from the Dead: Twice, once upon being reborn as a Cephalon, and again once he regains his human form.
- Came Back Strong: While he was an incredibly deadly warrior, and coming from a universe where trained warriors can easily deflect bullets Ordan was already powerful, but a Badass Normal by Warframe standards. Upon his resurrection as he receives a quirk and the Required Secondary Powers that increase his strength to the point he can somewhat keep up with Natah during training.
- Heel Realization: Cites an encounter with a child spying on his forces for the enemy as the start of this, leading for him to realize that they were all just fighting for the Orokin's entertainment.
- I Hate Past Me: Disgusted and horrified with his past self, to the point of attempting suicide once he regains his memories, but instead chooses to Mind Rape himself back into obliviousness. He does this multiple times despite his own recorded warnings not to dig too deep into his past.
- Interrupted Suicide: Whenever he rediscovered his past as Ordan he would attempt self-termination, stopped either by his thoughts of Haylee or directly by her the final time.
- Mind Rape: First by the Orokin, turning him into a servant for the Tenno and unwitting spy. Self-Inflicted multiple times after he researches his fragmented memories.
- Mood-Swinger: Downplayed, he still has violent outbursts but to a lesser degree to canon after becoming human again.
- Morality Chain: Haylee is this to him, being the reason he didn't go through with self-destruction as a Cephalon. Natah is this to a lesser extent.
- Parental Substitute: Attempted to be this when Natah underwent her Face–Heel Turn after being brainwashed by Ballas. Averted as he knows that Haylee will likely never view him as a parent, but resolves to be there for her as a friend.
- Trademark Favorite Food: Soy Sauce, the first thing he had with his food upon regaining human form. He puts it on most of his food, much to the disgust of other characters.
The Void and Inside Haylee's Mind
The Man in The Wall
- Ambiguous Gender: Always referred to as "it" whenever it speaks.
- Anthropomorphic Personification: Of the Void, or at least heavily implied to be.
- Blue-and-Orange Morality: Views reality as a sandbox for it to play with, and people as toys. Has no concern over conventional human morality.
- Brutal Honesty: Straight up tells Haylee that it planned to take over her body, and the exact terms of the deal to save the survivors of the Origin system. Ambiguous as to whether it was telling the truth.
- Doppelgänger: Whoever it is speaking to sees it as a copy of themselves with golden eyes.
- Eldritch Abomination: An eldritch god and avatar of the Void. Appeared as both corrupted copies of the ones it talked to, and in his Vitruvian man form before sending the Origin System survivors to a new universe.
- Mutual Kill: Against the goddess of the MHA Universe.
- Slasher Smile: Has a penchant for this when mocking someone.
Vestige of The Wall
- Anthropomorphic Personification: Of the Man in the Wall's intentions.
- Doppelgänger: Of Haylee, at least inside her mind.
Umbra
