The King of Steam (蒸気王, Jōki-Ō?), a mathematician turned scientist from the 19th centuryWP who dreamed about the revolution of the world. He was known as a prodigious great scholar, employing a steam engine to invent the first computers in the world, the Difference EngineWP and the Analytical EngineWP.
Although known as the father of the computer in modern times, he died halfway through his projects, leaving both machines uncompleted and having his envisioned future "vanish into the threshold of the eras."
Caster possesses a strict personality, but displays a weakness towards innocent females and astute females.
During life, he possessed a dream of a "possible future" that vanished with his death, but that future manifests with him in his current form.
He wishes to use the Holy Grail for the "the advent of a world of steam civilization", but also feels that the modern world itself is not too bad after acquiring knowledge of it upon being summoned. He can be described as a "reliable ally" depending on the nature of his Master.

Fourth Singularity: London
Commanded by Solomon, Babbage, Makiri Zolgen, and Paracelsus von Hohenheim join together to destroy the era regardless of their lamentations towards the incineration of humanity. They invaded the Clock Tower through its entrance in the British Museum, which was destroyed in the process, and kill all the mages there to remove any opposition. After his group created a chamber deeper underground, Babbage constructed a massive steam engine dubbed Angrboda, which uses the Holy Grail as its power source. Angrboda then released the Demonic Fog on to the city to eventually destroy the era. Babbage’s Dimension of Steam is responsible for the Helter Skelter robots that roam London. Because of the Singularity’s distortions he is considered alive despite being a Servant that materialized from the fog.
He is present alongside Makiri when Paracelsus returns to Angrboda's chamber to report Jack the Ripper's loss. As the three agree to continue the project, Babbage laments they cannot follow the scholar's destiny to pave the path for the world and civilization due to the Incineration of Humanity.
Babbage is later found by Ritsuka, Mash, and Mordred thanks to Frankenstein leading them. He introduces himself as a leader of Project Demonic Fog and reveals he materialized from the fog. He laments the Incineration of Humanity while revealing the Helter Skelters manifest from him. Mordred tells him to hear what Frankenstein has to say. Babbage prepares to surrender when he goes berserk against the group due to Makiri using the Grail. After he is defeated, Babbage tells the group to head deep underground, where they’ll find Angrboda, the fog’s source powered by the Grail. He apologizes to Frankenstein, saying he is merely an improbable Servant of irrelevant thoughts. He then disappears confessing he doesn’t wish to end the world even though his dream will not be realized.
Event: Saber Wars
Babbage, Sakata Kintoki, and Nikola Tesla locate Mysterious Heroine X's ship, having been told it's a source of evil by a voice from a lens that fell from the sky. Babbage finds the ship flawed or incomplete, noting the lack of cogwheels, a lubricator, and a steam engine. He, therefore, decides he must reconstruct the ship himself. He, Kintoki, and Tesla then fight Ritsuka's party after EMIYA asks Artoria Lily to demonstrate how she has improved. After the fight, Babbage finds it nostalgic for a Servant to dream, though he understands from his experiences in London that dreams are a human privilege. He then warns Ritsuka and Artoria Lily that X's ship isn't a transporter of dreams and disappears.
Final Singularity: Solomon
Summer Event: Dead Heat Summer Race!
Due to complaints from Chaldea's staff about his steam making it even hotter, Babbage is asked to spend his summer in London. Frankenstein soon finds him and tells him about Ishtar's race. Babbage agrees to be her partner but notes his steam would defeat the purpose of why she joined the race. James Moriarty hears their predicament and agrees to help for a fee. Frankenstein and Babbage both agree that he has an ulterior motive but understand they have no choice but to accept his help. Then, taking a page from Chaldea's guide on how to deal with evil Servants, Frankenstein asks Moriarty for help while calling him papa. Moriarty immediately agrees to help, elated to have a daughter. He then confesses he successfully modified Babbage with the ability to transform into a vehicle beforehand, having used hypnotism to erase his memories. He activates the transformation and starts boasting of their victory when Frankenstein hits him for modifying Babbage without permission. She forgives him, though.
Afterward, Moriarty gives Frankenstein a swimsuit and modifies her weaponry, causing her to class change into a Saber and become able to use regular speech. Then, changing into her swimsuit, Frankstein and her team meet Ritsuka, Mash, and Ishtar to officially register for the race. Babbage even goes into vehicle mode to show they have a vehicle ready.
At the racetrack, Babbage and Frankenstein tell Ritsuka and Mash that they accept their team is a bit shady with Moriarty in it. Babbage also assures them that Moriarty has agreed to assume nearly all responsibility if something happens during the race. Ishtar then shows everyone the ritual tools, which are key to erasing the Singularity, and indicates a team is a legit participant. They’re designed to integrate into the vehicles, and any vehicle trying to race without them is automatically disqualified. After commentary on each team from Ishtar, the race begins.
A group of thugs soon appear before the racers. After the thugs are defeated, their leader, Atalanta, arrives. She considers the thugs to be her children to the racers’ confusion. Calling the wasteland the Atalanta Plains, she tells the racers that its roads lead to where she and her children planted Seed Apples. They are essential to her children‘s future, so she cannot permit them to be destroyed in the race. Everyone ignores her but soon learns she planted land mines to protect the seed apples. Atalanta is eventually defeated, and the racers move on to the next area.
The race brings everyone to an active volcano, where they meet Boudica at its crater. She offers to cook them something, only to turn hostile. Her hostility is due to what happened to Britannia and the fact she doesn’t have a playable swimsuit version this year despite modeling in one last year. She has become an Avenger, believing she must utterly break the racers’ spirits to protect her homeland. She will do so through a game of chicken to the mouth of the volcano, setting it up so the racers can’t cross the volcano until they beat her. The racers accept her challenge. Frankenstein's team soon gets cut off from the others by a stream of lava. Babbage says he can vent steam to fly them over it, but he worries that Ishtar may shoot them down for breaking the rule on flying. He turns off Locomotive mode and declares he'll vent steam to leap instead. With Frankenstein sitting on his head and Moriarty following from behind, Babbage continues the race, albeit at a slower speed.
Eventually, the racers arrive at a river. Penthesilea appears and explains the more beautiful they are, the faster they will go. She introduces them to the judges: Mister B, who judges their personal beauty, and Leonardo da Vinci, who judges their vehicles’ beauty. As the race continues, Moriarty modifies Frankenstein's Spirit Origin to change her regular swimsuit into bandages, something Babbage. This outfit change gets a very positive reaction from Mister B, which in turn gives Frankenstein's team a massive speed boost. Babbage tells Moriarty he would've thrown him into Mister B if their speed didn't improve for what he did to Frankenstein. Helena Blavatsky's team also gets a speed boost. While the other teams beat up Mister B (who turns out to be Blackbeard in disguise) for his double standards, Frankenstein and Helena's teams become neck in neck in the race. But near the end of the course, they see Penthesilea, who swam all the way there. Given the course's rules, Penthesilea believes her beauty gave her a boost in speed. Refusing to be considered thus, she tries to force the teams back to the start. Frankenstein and Helena's teams defeat her and continue the race
The racers soon enter the fourth area, which has breast-shaped hills. Artemis and her copies fire upon them, warning they cannot go through Artemis Valley as they please. She will allow them to pass if they can find the real Orion among his copies and return him to her.
The racers reach the final area, a bridge over a large ravine, with the Ishtar Temple at the finish line. With victory on the line, Babbage activates his Explosive Steam Turbo Boost. However, everyone is sent plummeting when someone cuts down the bridge.
Summer Event: Death Jail Summer Escape
The racers find themselves at the bottom of the ravine. They’re attacked by the Hessian Lobo security system, which overwhelms them. Medb then arrives and arrests the racers for placing weird textures on her land without permission. The racers fall unconscious and wake up in Medb’s prison. They find out that their powers are negated within prison. Medb tells the racers that she locked their vehicles up somewhere outside the prison after sensing a strange power from them. The racers are then brought to their cells, where they soon meet Ishtar’s avatars. They then encounter Carmilla working as a prison guard. Carmilla determines they're too weak to escape and opens their cells.
In the courtyard, the racers meet Gorgon, who's only brought out of solitary confinement, exercise. She agrees to tell them about the prison if they help with exercises. However, the fight is soon interrupted by Florence Nightingale, who leaves after Gorgons says none of them are injured. Minamoto-no-Raikou deduces Gorgon is a projection of her real self inside her cell. Gorgon confirms thus then reveals it's impossible to destroy the prison’s barrier from either the outside or the inside. However, the racers can take advantage of Medb’s overconfidence in her Prison Field to find blind spots to escape. Carmilla then brings the racers back to their cells.
The next day, the racers still haven’t found an escape route. They see Quetzalcoatl training other prisoners to be luchadors After some sparring, the racers are sent back to their cells. They then follow Ritsuka’s advice to dig their way out of the prison.
However, the racers' tunnels all converge onto Gorgon's cell, chained there by divine steel. Gorgon agrees to help them escape if they defeat Nightingale, who's about to spray her with reptile sanitizer. After Nightingale is defeated, Nero Claudius determines they can use Gorgon’s acid to clear any obstacles that bar them while digging. Since they had a deal, Gorgon spews acid into special containers for each team.
Unfortunately, while digging, they discover the Prison Field extends underground. They return to Gorgon's cell, who seems to be enjoying their predicament. After venting their frustrations, the racers realize they have no choice but to kill Medb to disable the Prison Field. Gorgon reveals there was another prisoner who tried escaping by killing Medb. She defeated them and revealed she has a conceptual weakness to projectile cheese. But Medb is always protected by her warriors. Gorgon reveals Medb always takes a shower in her warden’s office at the same time every day. Moriarty, Thomas Edison, and Nikola Tesla point out they need someone intelligent as them and Babbage, who also knows the prison’s layout if they want to successfully snipe Medb from outside her bathroom window. Frankenstein notices Mysterious Heroine X staring at her really hard. Babbage tells her to hide in his body if things turn for the worse. Gorgon reveals there is a prisoner who knows everything about the prison, despite being in solitary confinement. She then gives the racers general directions to that person's cell.
They dig into the prisoner’s cell, who turns to be Enkidu in tight restraints. After Raikou cuts their restraints, Enkidu has the racers spar with them to see if they’re fully functional. Enkidu afterward then agrees to provide the racers with the necessary calculations. Carmilla arrives to feed them, and attacks everyone after seeing Enkidu unrestrained. After defeating Carmilla, Enkidu, Babbage, Edison, and Tesla make blueprints for their cheese-apult.
After building it with the materials Ritsuka provided, the racers use the cheese-apult to assassinate Medb while she’s in the shower. However, Medb kicks the cheese away thanks to training her body to automatically react to incoming cheese. Enkidu reveals there is another way to remove the Prison Field, one only they know of. They reveal the control device for the Prison Field is a stone above the ground. The racers soon realize it’s in the statue of Medb in the courtyard. Enkidu then reveals there is a prisoner who is master of disguise that the racers can use to trick Quetzalcoatl into disabling the Prison Field. The racers then dig their way to the prisoner’s cell.
They arrive in the prisoner's cell, only to find Carmilla there to their shock. They fight her, but in the midst of it, she turns into Nightingale. After being defeated, she reveals herself to be Yan Qing in disguise. He agrees to disguise himself as Medb to trick Quetzalcoatl into disabling the Prison Field in exchange for fighting him. But Raikou has him sit in the corner and lectures him until he gets sore. Afterward, Yan Qing (disguised as Med) gets Quetzalcoatl to disable the barrier underground, allowing the racers to reach their vehicles in the warehouse.
The racers escape to the outside, where Medb and Quetzalcoatl confront them. Medb deflects shots from X's cheese blaster and decides to execute the racers, accusing them of covering Connacht with textures of another place. The racers defeat Medb and Quetzalcoatl, then return to the race once they disappear.
If Frankenstein's team is in the lead, Babbage activates his Explosive Steam Turbo Boost at maximum output. He calls Moriarty a dastardly villain for throwing mayonnaise at the other racers. But he decides to let it go after Moriarty responds with might makers right.
After the race, however, an enormous storm moves toward the track as if it has a will of its own. Ishtar reveals this was her plan. Unbeknownst to the racers, their vehicles’ tires were carving magical energy into the Venus textures she placed on the land. She then reveals her temple to be a giant ATM called the Ishtar Quantum Power System. The racers confront her when the relics she had them install in their vehicle are suddenly removed. The relics converge at the Ishtar QPS, which gathers the magical energy expended in the race. At the same time, the relics were storing the heat created by the friction of the racers’ tires running across the Venus textures for each relic to reach an excited state. The purpose of all this was for Ishtar to create a new Gugalanna. After using the relics and the Ishtar QPS to do so, she declares she can use him to destroy the Singularity. Da Vinci points that would work, but it’d also destroy Connacht. The racers then fight Ishtar and Gugalanna before he’s completely formed, but they struggle against him. Quetzalcoatl then arrives to attack Gugalanna, revealing the her that disappeared before was Yan Qing in disguise. After she destroys Gugalanna, the racers and the race’s administrative staff get their picture taken by Georgios.
If Frankenstein's team won, they return to Chaldea to celebrate. Babbage is surprised Moriarty used their leftover winnings to create a device to absorb his steam exhaust. He used that steam as fuel for cosmetic steam products. But he and Frankenstein wonder what happened to Moriarty's evil schemes. Moriarty admits it was completed long ago but assures Frankenstein and Babbage that it won't harm either of them. Frankenstein and Babbage are confused by this.
Hell Realm Mandala, Heiankyo - Flash of Roaring Thunder
Babbage is summoned by Murasaki Shikibu as her Servant.
In his interlude, Iron Mobile Report C. Babbage, Babbage and Ritsuka go to rescue Mash, who's playing the role of a princess. After the pair defeat the one threatening Mash and her kingdom, it's reveal what transpired was a dream Ritsuka saw.
Following several modifications made by James Moriarty, he can also shapeshift into a fully functional locomotive.
- Item Construction (Fake) (A Rank): Babbage who was originally not a mage can not possess this skill, but by integrating with his Noble Phantasm, an ability equal to it is acquired. Specifically, it's his armor of steel manufacturing armaments and miracle drugs.
- Single-Mindedness (C Rank): It displays the superhuman power of concentration by devoting oneself to a single thing. In Babbage's case, his behavior towards calculations, plans, production and the like is demonstrated. It functions as a bonus correction for his Item Construction skill.
- Mechanized Armor (EX Rank): Always clad in a full-body mechanical armor that's equipped with a steam engine. Due to this, Babbage looks like a giant gentleman of steel. Removal is impossible. While physical Strength and Endurance parameters are ranked up, at the same time, a temporary [++] correction is given by the built-in, strange-looking steam engine's boost function. Although the Agility stat is ranked down, the boost is added. By the way, Babbage's been smitten with automatons since he was 8. It's said, that the first one he saw was a female model he met in the workshop of an inventor called Merlin.
- Overload (D Rank): Accepting the risk of self-harm, a "boost up" effect is intentionally applied. In Babbage's case, the armor's steam engine is made to rampage on a purpose to raise its output and increase the offensive ability of his Noble Phantasm. The damage the steam engine suffers from rampaging is received by Babbage too due to being integrated with the armor.
