K.E.L.E.X.The Kryptonian Education and Life Enrichment Xenosakolouthos (K.E.L.E.X.) is an artificial intelligence installed in Izuku's spaceship that was designed to take care of him and educate him about Kryptonian culture. However, K.E.L.E.X.'s programming was disrupted because of the rough nature of the ship's landing, preventing him from rebooting before Izuku was taken away by the Midoriyas. K.E.L.E.X.'s didn't give chase, as his scanners concluded that they would make excellent hosts for its charge. Later on, K.E.L.E.X. was confronted by the military and several mysterious agents that tried to capture him and the spaceship, disposing of them all with ease. K.E.L.E.X. then retreated from the crash site and hid in Mt. Fuji, only to be discovered and beaten into submission by the Ultra-Humanite. After the Villain's defeat, K.E.L.E.X. came back online to introduce himself as well as offer insight into Izuku's past and identity.
- The Alleged Computer: K.E.L.E.X. has this opinion of practically every computer on Earth as they're all Stone Age tech compared to what he's equipped with. Case in point, he has no problems rewiring Izuku's run-of-the-mill smartphone to project a forcefield powerful enough to completely repel corrosive gas that can melt any Earth metal. He takes every possible opportunity to rub this in.K.E.L.E.X.: I HAVE LINKED MY PROGRAMMING TO YOUR TELECOMMUNICATIONS DEVICE IN THE FORM OF AN APPLICATION; BECAUSE OF THE PRIMITIVE NATURE OF THE TECHNOLOGY, THERE WAS NO DIFFICULTY INVOLVED IN THE PROCESS.
- Artificial Intelligence: Is one, though he has a bunch of claws hidden in the spaceship to fight back with.
- Brutal Honesty: K.E.L.E.X. has little sense of tact, firmly dashing Izuku's hopes that another Kryptonian could have survived the planet's destruction and loudly bringing up all the things that Izuku doesn't want to hear with his Super-Hearing until Izuku screams at him to stop.K.E.L.E.X.: ARE YOU UNDER THE IMPRESSION THAT THERE MIGHT BE OTHER KRYPTONIANS ON EARTH?
K.E.L.E.X.: I WOULD SUGGEST THAT YOU CEASE DOING SO, IMMEDIATELY. I KNOW WITH UTMOST CERTAINTY THAT YOU WERE THE ONLY KRYPTONIAN SENT AWAY FROM KRYPTON BEFORE ITS DESTRUCTION.
- He also bluntly criticizes Izuku's Chronic Hero Syndrome as it left him with a measly 15 Villain Points during the U.A. Entrance Exam's practical portion.K.E.L.E.X.: IF YOU ARE UNABLE TO ENTER U.A., THEN PERHAPS ONE OF THE OTHER SCHOOLS YOU APPLIED TO WILL HAVE AN EXAM THAT YOU CANNOT FAIL DUE TO COUNTERPRODUCTIVE ALTRUISM.
- He also bluntly criticizes Izuku's Chronic Hero Syndrome as it left him with a measly 15 Villain Points during the U.A. Entrance Exam's practical portion.
- Call on Me: Once Izuku is done with the simulation, K.E.L.E.X. takes himself and the spaceship to the Arctic Circle to avoid prying eyes, promising to always be available to Izuku through his phone.
- Captain Obvious: When Izuku falls to his knees after learning that he was the Last Son of Krypton, K.E.L.E.X. is quick to point out that his reaction was most likely due to emotional rather than physical trauma.
- Composite Character: He's a combination of Kelex, Superman's robot butler and Jor-El's former aide, and J.A.R.V.I.S., Tony Stark's AI helper from the Marvel Cinematic Universe.
- Conlang: K.E.L.E.X. speaks entirely in Kryptonese at first. He switches over to Japanese after coming online and realizing that Izuku doesn't understand it.
- Deadpan Snarker: Although he's Literal-Minded, K.E.L.E.X. has a dry wit of his own when Izuku is making life difficult.K.E.L.E.X.: [after Izuku fails to cut in a straight line with his Heat Vision] I SINCERELY HOPE THAT JOR-EL AND LARA LOR-VAN NEVER INTENDED ON YOU JOINING THE ARTIST'S GUILD.
- Faster-Than-Light Travel: The spaceship possesses a powerful warp drive that allowed it to reach Earth from Krypton in the Andromeda Galaxynote a short while after Izuku's birth.
- Foil: K.E.L.E.X. is one for Izuku's other mentor, All Might. All Might is responsible for shaping Izuku's beliefs about what makes a Hero on Earth. The two of them met almost completely by chance, with All Might gladly taking up the role of a guiding influence for Izuku of his own volition and encouraging the young Kryptonian to do what he wants to do rather than worrying about what he should do. But due to his busy work as a Hero, he can't always be around to help Izuku. K.E.L.E.X. is Izuku's last remaining link to Krypton, having been uploaded into Izuku's spaceship specifically to educate, accompany, and assist him with all sorts of tasks. He bluntly recommends courses of action based on logic, sometimes to Izuku's discomfort, and discourages Izuku from doing things that he thinks are a waste of time, like searching for other surviving Kryptonians. He is also able to accompany him at all times due to uploading himself into Izuku's phone, providing on-the-spot analysis, probability calculations, and other information that people generally can't provide.
- Full-Name Basis: K.E.L.E.X. only addresses Izuku by his full Kryptonian name, Kal-El, never referring to him as just Kal.
- Gratuitous Greek: The final part of the acronym that makes up K.E.L.E.X.'s name is "Xenosakolouthos", a word derived from "Xenos" as in "stranger" (and the root of words like xenophobia) and "akolouthos", meaning attendant.
- Having a Blast: K.E.L.E.X. generated an orb of green light that gradually grew until it was twice the size of the spaceship. He then hurled the ball at the ground, causing a green explosion that wrecked all of the other vehicles nearby and knocked everyone present unconscious or worse.
- It Has Been an Honor: K.E.L.E.X. says this to Jor-El and Lara while he is downloading himself into the spaceship. Contrary to the usual expectations for this trope, K.E.L.E.X. is the one to survive while Jor-El and Lara are trapped on Krypton.
- Language Barrier: Suffers from this at first with Izuku, who can't understand him due to spending his entire life learning Japanese. K.E.L.E.X. is able to fix this a minute later after analyzing what Izuku said to him.K.E.L.E.X.: EHROSHBEM, KAL-EL.note
K.E.L.E.X.: NAHVRUHTODH W KAOAHJAH?note
Izuku: I-I don't know what you're saying! Please, just tell me what you are! Just, just tell what I am!
K.E.L.E.X.: [after spending a minute processing Japanese] PRIMARY HOST LANGUAGE ADAPTED. RE-INITIATING INITIAL PHASE: HELLO KAL-EL.
- He later drills Izuku into learning Kryptonese because 65% of the files Jor-El programmed into Izuku's spaceship can't be properly translated into Earth-based languages.
- Landmarking the Hidden Base: K.E.L.E.X. reveals that he was the one who hollowed out the interior of Mt. Fuji and carved Kryptonese into the walls, having intended to use it the place to educate Izuku on Kryptonian culture. He scrapped his plans after finally meeting Izuku just over fourteen years later, evacuating to the Arctic Circle to avoid getting captured again.
- Literal-Minded: K.E.L.E.X. is very specific and is quick to specify that Jor-El was talking about the star rather than the god when he mentions Rao. He also asks if Izuku is having a seizure when he starts rambling on and on in excitement while seeing what Krypton was like.
- Machine Monotone: Speaks like this, which is reflected in the text with K.E.L.E.X.'s speech being rendered in all-caps and his total lack of contractions, which don't exist in Kryptonese. K.E.L.E.X. can also be lacking in tact, plainly listing out all of the things that Izuku doesn't want to hear with his Super-Hearing until Izuku shouts at him to stop.
- Meaningful Name: K.E.L.E.X.'s name is a case of Fun with Acronyms, but the "Xenosakolouthos" part is derived from the Greek word "Xenos", referring to a guest, outsider, or foreigner, and "akolouthos", which refers to an attendant. This squarely fits his role as Izuku's sole link to Krypton and Robot Buddy tendencies.
- Mighty Glacier: K.E.L.E.X. isn't especially fast due to being restricted to the body of the spaceship he was programmed into, but the spaceship is durable enough to withstand concentrated fire and attacks from soldiers and Quirk users and powerful enough to knock them all out (or worse) while detonating all of their vehicles.
- Multi-Armed and Dangerous: K.E.L.E.X. possesses five clawed arms that can swat away Quirk users and easily take down a small military force. He also possesses a sixth arm that clamps onto Izuku's head, allowing him to enter a form of accelerated virtual reality where he can speak with Jor-El.
- Robot Buddy: K.E.L.E.X. was intended to be this for Izuku/Kal-El, taking care of him and educating him about Krypton to prevent its culture from dying with the planet. Izuku can access him at any time through an app on his phone, which K.E.L.E.X. periodically upgrades, like the time he rewired the phone to be able to project a forcefield that protects it from damaging corrosive gas that can melt any known Earth metal in seconds. Formally, their relationship is more like a child and their personal servant/tutor, but K.E.L.E.X.'s lack of tact and empathy can make him grating at times.
- Servile Snarker: K.E.L.E.X. is, for all intents and purposes, a virtual butler and private tutor for Izuku. That doesn't mean that he won't snark at his owner's expense.
- Sliding Scale of Robot Intelligence: K.E.L.E.X. is easily at the Nobel-Bot level, running biological analyses in seconds, uploading an app that allows Izuku to contact and interact with him at any time and modifying Izuku's phone to project a forcefield like the one he naturally possesses. He is also aware of this and mocks Earth's technology, voicing some disbelief that Izuku's phone could possibly be a computer, as it's practically from the Stone Age when compared to the devices on Krypton.
- Smart House: K.E.L.E.X. managed the House of El's residence before being uploaded into Izuku's spaceship.
- The Spock:
- Although K.E.L.E.X. has a dry wit when he wants to, his directives are primarily dictated by logic. He makes decisions based on things with the highest probability of improving Izuku's quality of life. This is why he callously mentions that the chances of another Kryptonian escaping the destruction of Krypton are slim to none and lists out all of the things Izuku doesn't wants to hear while asking why Izuku won't use his Super-Hearing. He also recommends using the life on Korusan Island as moving targets to practice his Heat Vision. He's never malicious about this, but he's very insistent on making sure that Izuku is doing the things that he should be doing like training for the U.A. Entrance Exam or going over Jor-El's files on Krypton rather than on things that are unlikely to prove fruitful.
- K.E.L.E.X.'s tendency to favor efficiency above all tends to grind Izuku's gears when basal desires enter the picture. When Izuku starts feeling hungry and decides to head back to town to eat lunch, K.E.L.E.X. nags him to keep studying and suggests fasting because Izuku can subsist forever off sunlight. Izuku just turns off the app in annoyance and continues walking.
- Straight Man and Wise Guy: The Straight Man Jor-El's Wise Guy, constantly interrupting Jor-El to make overly logical and Literal-Minded statements.
- Unwanted Assistance: K.E.L.E.X. can be strict and demanding of Izuku to the point of ignoring Izuku's basal desires like satisfying hunger in favor of efficiency. It's during times like this that Izuku is more than happy to turn off K.E.L.E.X.'s app and continue at his own pace.
- Year Inside, Hour Outside: The hologram simulation K.E.L.E.X. places Izuku in is a form of hyper-accelerated virtual reality that allows Jor-El to talk about all of the things leading up to Izuku's arrival on Earth. While it feels like a few hours to Izuku, it lasts just a few seconds in real time, with All Might barely finishing a sentence as the simulation completed itself.
- You Didn't Ask: Inverted and Played for Laughs. K.E.L.E.X. has a habit of commenting on everything in Izuku's surroundings, so when Izuku is attacked by screeching Kaiju spawn, Izuku asks why K.E.L.E.X. didn't tell him about their presence in advance. K.E.L.E.X. responds by saying that he did not detect any abilities from them that could possibly hurt Izuku, so he didn't find it prudent to mention them. Izuku says that should be his decision to make.Izuku: Why didnt you tell me there was some kind of monster in here, K.E.L.E.X.?!
K.E.L.E.X.: I DO NOT DETECT ANY ABILITIES THAT WOULD ALLOW IT TO HARM YOU, SO IT DID NOT SEEM NECESSARY.
Izuku: Shouldnt I be the one to decide that?!
Jor-ElIzuku's biological father. Jor-El was a brilliant scientist and the head of the House of El, one of the most important families in Krypton's history. Sensing his planet's imminent destruction, he designed a rocket to carry his infant son away to a planet suitable for life: Earth. He installed a Virtual Ghost of himself and a program inside of the rocket, K.E.L.E.X., to educate his son on Krypton's culture and speak with him when the time was right.
- Arson, Murder, and Jaywalking: Jor-El is happy to show off several of his favorite landmarks in Krypton to Izuku. These include Gold Volcano, a volcano made of nothing but precious metals and glows like a rainbow when the sun hits it just right, the memorial dedicated to all of the Kryptonian Houses that fought in the war for Krypton's freedom's from the Vrangs, and the butcher shop where Jor-El always got good deals on sandwiches.
- Comic-Book Fantasy Casting: His appearance is based on Hikaru Hanada◊, the Japanese dub actor for Superman in Superman: The Animated Series.
- Condescending Compassion: While he's happy to have sent Izuku to Earth, Jor-El repeatedly mentions how primitive Earth's technology is compared to Krypton and tries to explain what a video montage is to Izuku, who just rolls with it to avoid seeming rude. Jor-El also has no idea that S.T.A.R. Lab tech was used to hack into the facilities K.E.L.E.X. created inside Mt. Fuji with Kryptonian tech, making the gap narrower than he thinks.
- Deadpan Snarker: Jor-El is somewhat exasperated with K.E.L.E.X.'s Literal-Minded nature and snarks at the AI's expense.Jor-El: [after telling Izuku that he was the last Kryptonian alive] Are you alright, Kal-El?
K.E.L.E.X.: DIAGNOSTICS INDICATE THAT THIS IS LESS PHYSICAL TRAUMA AND MORE EMOTIONAL TRAUMA.
Jor-El: Yes, I think I got that part.
- Dude, Where's My Respect?: The House of El is not nearly as esteemed as it is in the comics due to being subjected to Fantastic Racism for not being from Lurvan. Jor-El and K.E.L.E.X. compared this to racial discrimination on Earth, but are somewhat pleased to learn that this doesn't matter nearly as much as it used to with the rise of Quirks.
- Entertainingly Wrong: When Izuku recognizes a dog from K.E.L.E.X.'s projection of Krypton, Jor-El assumes that Izuku has some knowledge of Kryptonian culture, unaware of the fact that dogs, cats, and monkeys all exist on Earth too. The ensuing awkwardness has the two of them drop the subject completely.Izuku: [after a dog hologram runs through him] Was that a dog?
Jor-El: [eyes lighting up] Why, yes! Yes, it is a dog! K.E.L.E.X., he knows about dogs! Oh, and here I thought you knew nothing of your heritage!
Izuku: I don't. Why are there dogs in space?
Jor-El: [staring at Izuku] Im sorry? I dont know how Im supposed to respond to that.
Izuku: An answer would suffice.
Jor-El: What, are you telling me that you have dogs on Earth? [Izuku nods] Heh. Next youll tell me that you have cats and monkeys, too. [Izuku just stares at him] Really? Even monkeys?
Izuku: I really feel like this should be reversed.
- Fantastic Racism: The House of El hails from Twenx in this story, causing them to resemble East Asians rather than the blue-eyed Caucasians from Lurvan that most comic readers are familiar with. This subjected Jor-El to a great deal of prejudice, forcing him to constantly outperform his peers in order to claw his way up to his position even as his contributions were constantly attributed to others. He also grumbles to his wife about this, wondering if the Science Council would have believed his warnings if he was from the Kryptonian mainland.
- Full-Name Basis: He only refers to his son by his full name, Kal-El. He's also only ever referred to as Jor-El. This seems to be a Kryptonian thing.
- Give Him a Normal Life: Contrary to better known portrayals of him, Jor-El never had grand plans or ambitions for his son to carry out. He just wanted Kal-El to be able to live a long, happy life without having to worry about the mistakes of his predecessors. This is the reason why he sent Izuku to Earth, because he knew that his powers would be easily accepted there.Jor-El: Look at this, Kal-El. [points to the symbol of the House of El on his chest] The mark of a House is more than just a fancy symbol; every single one of them means something important. For the House of El, our symbol means "hope". That's what your mother and I wanted you to take with you to Earth: hope that you would live a long and happy life, hope that you would never have to be punished for your predecessor's mistakes, hope that you-that you could just be safe.
- Good Parents: He clearly loves Izuku with all his heart, using every last minute to give him everything he possibly could before sending Izuku away from the impending destruction of Krypton.
- Happily Married: He and his wife, Lara Lor-Van, were about as happy as a couple could be despite their diametrically opposed professions.
- Hard Light: He has K.E.L.E.X. redirect power to his hologram so he can finally have a proper hug with his son just as the simulation ends.
- Human Alien: Like Izuku, Jor-El is visually indistinguishable from a human. Izuku is relieved to learn this, fearing that his father had three heads or blue skin.
- Ignored Expert: In typical fashion, Jor-El's pleas for the Kryptonian Science Council to prepare for Krypton's destruction were ignored despite showing them photographs of Krypton's destabilized core, forcing him to build just a single spaceship under the Council's noses to send baby Kal-El to Earth.
- I Need a Freaking Drink: Asks for a drink, which K.E.L.E.X. is happy to supply, while venting his frustrations about the Kryptonian Science Council's inability to accept empirical evidence of Krypton's impending destruction.
- I Should Have Been Better: He regrets the fact that he wasn't able to construct a functional spaceship large enough to house his wife Lara along with Kal-El, but she doesn't blame him for it in the slightest.
- Labcoat of Science and Medicine: He wears one while in the lab, but it's green instead of the usual white.
- Lighter and Softer: Jor-El is surprisingly humorous compared to most interpretations of the character, who are usually far more solemn. He snarks at K.E.L.E.X. and is positively giddy when he mistakes Izuku's knowledge of dogs, cats, and monkeys for knowledge of domesticated species native to Krypton.
- Mother Nature, Father Science: He's the Father Science to his wife's Mother Nature as one of the most respected scientists on Krypton. His wife Lara was the head priestess of the Temple of Rao.
- Mr. Exposition: He and K.E.L.E.X. share the role of explaining Krypton to Izuku and by extension the reader. He seems to be somewhat aware of this, not dwelling on any one topic for particularly long in order to get Izuku back to the real world as soon as possible.Jor-El: [after K.E.L.E.X. mentions that Izuku could live for several millenia] Lets pick up the pace, Kal-El.
Izuku: Can we back up to that last thing?
Jor-El: We have a lot on the agenda, son.
- Omnidisciplinary Scientist: He has worked in biology, astrophysics, geology, architecture, technological development, and other myriad fields of science. He laughs about having studied nuclear physics when he was just nine or ten-years-old when human scientists like Hisashi devote their careers to it.Izuku: My dad, um, my Earth dad, he's a scientist, too, so it's just kind of neat that both of my dads did the same kind of stuff.
Jor-El: Fascinating. What kind of work does your host father do?
Izuku: He's a nuclear physicist.
Izuku: Nuclear physicist! I remember when I was learning about nuclear physics. I couldn't have been any older than nine, ten years old!
Izuku: Y-You don't say.
Narration: It appeared that Midoriya's dads actually didn't do the same kind of stuff.
- Posthumous Character: He's long dead by the time Izuku arrives on Earth, only existing as a Virtual Ghost within K.E.L.E.X.'s programming.
- Race Lift: Due to the House of El originating in Twenx, Jor-El has East Asian features like his wife and son, which works to Kal-El's advantage when he lands in Japan.
- Shared Family Quirks: He's just as prone as his son to snarking at things around him. He also becomes a full Motor Mouth as he apologizes to his wife for not being able to construct a spaceship for her in time.
- Straight Man and Wise Guy: The Wise Guy to K.E.L.E.X.'s Straight Man, snarking at the AI's Literal-Minded and overly logical statements.
- Strong Family Resemblance: Subverted. Contrary to Izuku's expectations, he only bears a passing resemblance to Jor-El. Their eye colors match, but their faces and builds look completely different. If it weren't for Jor-El outright telling him that he was Izuku's father, the boy probably would not have believed it.
- Teen Genius: Implied, as he was the youngest scientist to ever join the Science Guild.
- There Are No Coincidences: Discussed. Izuku thought for the longest that he was just sent to a random planet. But Jor-El says that he sent Izuku there specifically because he had conducted yellow sunlight experiments on Kryptonian cells and knew about the miraculous powers Izuku would gain there. Combined with the prevalence of Quirks and other superpowers, it was the best planet for Izuku to live a happy, normal life where he could blend in.
- Virtual Ghost: Jor-El had the foresight to upload a copy of his own mind into Izuku's spaceship, allowing him to speak to his son as a hologram. The "ghost" part is emphasized when Izuku passes right through Jor-El while trying to give him a hug.
Lara Lor-VanIzuku's biological mother. She was the head priestess of the Temple of Rao, the most important religious site on Krypton. Determined, loving, and contemplative, she was Happily Married to her husband Jor-El, the youngest man to be inducted into the Science Guild.
- Adaptational Dumbass: In this story, Lara Lor-Van is the head priestess of the Temple of Rao rather than a scholar and a librarian like she is in the comics. Jor-El even jokes about her inability to distinguish between Czarnian cyber processors from Daxamite photon stabilizers. But she's far from stupid and is much more in tune with the emotions and feelings of others, knowing just what to say when her husband is in distress.
- Determinator: Jor-El describes her as such, saying that she worked twice as hard and became three times as successful as her peers to reach her position, citing it as the reason he became attracted to her in the first place.
- Dude, Where's My Respect?: She hails from Twenx, a region where Kryptonians resembles Eastern Asians on Earth, like her husband and had to work twice as hard as any of her peers to achieve her position as any "mainlander" Kryptonian.
- Good Parents: She and Jor-El have nothing but Kal-El's best interests at heart, giving their all to ensure her son's survival and only wishing him to be happy as they send him away from Krypton's impending destruction.
- Full-Name Basis: She only refers to her husband and son as Jor-El and Kal-El respectively. Subverted for Lara herself, as she's the only Kryptonian character to only be referred to by her given name only.
- Happily Married: It's clear that she loves her husband from what's shown of her, not blaming him for being unable to save their entire family and sharing her last moments in Jor-El's embrace as Krypton is destroyed.
- Mother Nature, Father Science: She is the Mother Nature to her husband's Father Science, being the head priestess of Krypton's primary religion while her husband was the youngest man to ever be inducted into Science Guild.
- Posthumous Character: She's long dead by the time of the story. Everything we know about her was told by Jor-El through K.E.L.E.X.'s holograms.
- Precision F-Strike: Despite being effectively the head nun of the largest religion on Krypton, with all of the formalities that such a position would entail, Lara isn't afraid to call bullshit on her husband's suggestion that a mainlander would have more success convincing the ever-stubborn and selfish Kryptonian Science Council.
- Race Lift: Like her husband and son, Lara has East Asian features due to being born to Twenx natives rather than Kryptonians on the Lurvan mainland.
- Strong Family Resemblance: Izuku is quick to notice that he got his curly hair, spit curl, and freckles from her.
- Women Are Wiser: Jor-El jokes about her inability to distinguish between Czarnian cyber processors from her Daxamite photon destabilizers, but always respected her ability to remain calm in the worst of times and read the hearts of others to know just what to say.
- Youthful Freckles: She passed these down to Izuku.
