Chapter Summaries

Ratchet explained that he wanted to leave support work and fight alongside his comrades, prompting Rimuru to arrange upgrades for the Decepticons. Megatron approved the plans but questioned the battlefield value of Nitro Zeus’s speakers.

• Ratchet told Optimus Prime that he wanted the power to fight on the front lines and protect his comrades.
• Rimuru remembered Ratchet’s tragic fate in the original movie and vowed to punish the humans who betrayed him.
• Megatron protested that the Autobots kept getting upgrades while the Decepticons waited.
• Rimuru assigned upgrades to Bonecrusher, Brawl, Starscream, Soundwave, Barricade, and Nitro Zeus.
• Megatron approved the Decepticons’ upgrade plans but asked why Nitro Zeus needed two top-tier speakers.

Rimuru explained the purpose of Nitro Zeus’s speakers, then asked Ratchet what upgrade he wanted. Ratchet rejected his role as a rear-line medic and demanded the strength to fight on the front lines, leaving Optimus Prime and Megatron stunned by his reasoning.

• Rimuru explained to Megatron that Nitro Zeus’s speakers could boost his fighting spirit, disrupt enemy audio detection, and provide his own entrance music.
• Rimuru invited Ratchet to name the upgrade he wanted.
• Ratchet said his medical skills could not save comrades in truly critical condition and that he no longer wanted to remain behind the team.
• Ratchet demanded real combat power so he could fight beside his comrades and prevent their injuries by defeating enemies first.
• Optimus Prime tried to reassure Ratchet that the Autobots depended on him, but Ratchet argued that preventing danger was better than treating its aftermath.
• Megatron questioned whether Ratchet was really an Autobot and decided to ask Soundwave to investigate him.

Ratchet explained that he wanted to leave medical logistics behind and gain the ability to protect his teammates by ending threats himself, and Optimus Prime accepted his choice. Rimuru designed a hybrid medical and frontline combat form for Ratchet, which Ratchet approved.

• Ratchet told Optimus Prime he wanted to become a combat mech, and Optimus Prime respected his decision.
• Ratchet described his limitations and requested a heavy-armored melee style or a hybrid form that preserved his medical skills.
• Rimuru scanned Ratchet and concluded that a medical-combat hybrid suited his body better than an agile or fully heavy build.
• Rimuru proposed replacing Ratchet's armor with self-healing T-1000 liquid metal and giving it adaptable combat and repair forms.
• Rimuru planned to convert Ratchet's warning lights into an electromagnetic interference system while avoiding excessive lethal weapons.
• Ratchet approved Rimuru's modification plan as the form he wanted most.

Rimuru modified Ratchet by reinforcing his internal frame with Uru divine steel and coating him in self-healing T-1000 liquid metal. Ratchet believed he had become a frontline combatant, unaware that the upgrade had made him an even more powerful healer.

• Rimuru carefully reinforced Ratchet’s existing mechanical foundation without changing his frame or transformation system.
• Rimuru replaced Ratchet’s outer armor with T-1000 liquid metal and explained that Uru divine steel inside would bear heavy attacks while the outer layer could disperse force and form weapons.
• Rimuru revealed that the liquid metal could rapidly repair precision components, including transformation gears, as long as Ratchet’s Spark remained lit.
• Bumblebee, Jazz, Optimus Prime, and Megatron reacted with shock and envy to Ratchet’s battlefield self-repair capabilities.
• Ratchet imagined abandoning medicine to charge into combat, while Rimuru’s modification had actually turned him into an extraordinary battlefield healer.

Ratchet tested his newly upgraded liquid-metal body by sparring with Megatron, who had underestimated him. The fight left Megatron astonished by the armor’s ability to repair itself almost instantly.

• Ratchet tested his new body and eagerly sought an opponent to gauge his combat strength.
• The Autobots and their companions silently chose Megatron, who reluctantly agreed to spar with Ratchet.
• Megatron opened with a powerful probing punch that sent Ratchet stumbling backward but did not knock him down.
• Ratchet’s dented liquid-metal armor repaired itself completely within seconds, leaving Megatron impressed and envious.

Rimuru explained why T-1000 liquid metal was unsuitable for Megatron, despite its powerful self-healing ability. After Megatron called in the Decepticons for upgrades, Rimuru chose Starscream and Barricade to go first.

• Megatron coveted Ratchet's self-healing liquid-metal body and showed Rimuru that he wanted the same upgrade.
• Rimuru warned Megatron that extreme cold, heat, and strong acids could disable or destroy liquid metal, making it a poor match for Megatron's fighting style.
• Ratchet felt briefly disappointed that his new body still suited support work, then accepted his strengths and regained his composure.
• Megatron gave up on the liquid-metal upgrade and complained that Rimuru had brought up his embarrassing time frozen beneath Hoover Dam.
• Megatron called the Decepticons to line up, but they crowded the laboratory until Rimuru sent them back outside.
• Rimuru kept Starscream and Barricade behind to be upgraded first.

Rimuru continued upgrading the Transformers before Nick Fury arrived with the Flerken in exchange for the agent serum. Rimuru brought the orange cat into the laboratory, where the Transformers grew fond of it, though Ironhide kept his distance.

• Rimuru began tailored combat upgrades for Starscream and Barricade while the Autobots waited their turn.
• Black Dragon alerted Rimuru that Nick Fury had arrived alone at the surface base with a Flerken.
• Nick Fury handed Rimuru the orange cat and asked him to keep it safe, while Rimuru promised to deliver S.H.I.E.L.D.'s agent serum.
• Rimuru returned to the laboratory with the Flerken and asked Black Dragon to buy cat supplies.
• The Transformers gathered around the cat, which climbed over them, while Ironhide avoided it because it reminded him of a Chihuahua that had peed on his leg.

Steve Rogers visited Rimuru after finishing a mission against Hydra remnants and asked him to deliver custom-made silicone models to Wanda. Steve thanked Rimuru for helping him reunite with Peggy, but Rimuru realized his interventions might have cost Steve the chance to spend a full lifetime with her, leaving Steve confused by Rimuru’s sudden guilt.

• Ironhide grew wary of the Flerken and Rimuru after seeing them swallow objects many times their size.
• Steve arrived after leading teams to clear Hydra bases and capture undercover agents.
• Rimuru teased Steve about visiting Peggy, and Steve said their occasional meetings were enough to make up for the past.
• Steve gave Rimuru two custom-made silicone models for Wanda and asked him not to cause conflict with Pietro.
• Steve thanked Rimuru for the recovery potion that let him share a long-awaited dance with Peggy, and Rimuru wondered if he had changed Steve’s future ending for the worse.
• Rimuru grew guilty as he considered Peggy’s limited lifespan, while Steve became unsettled by the sudden change in his expression.

Rimuru offered Steve two ways to preserve Peggy Carter beyond her natural lifespan, but Steve insisted that Peggy must choose for herself. Steve hurried to find her, while Rimuru reflected that his actions had already changed Steve’s fate.

• Rimuru explained that he could create a virtual replica of Peggy or preserve her soul and give it a new body.
• Steve reacted with shock and hope, but said Peggy had to decide whether she wanted either form of continued existence.
• Rimuru agreed to respect whatever Peggy and Steve chose.
• Steve hurried toward town to speak with Peggy about their future.
• Rimuru watched Steve leave and wondered how his intervention had altered the predetermined course of fate.

Rimuru delivered Steve’s gift to Wanda, warned her to be wary of Kaecilius, and asked the Ancient One why his cultivation had stalled. The Ancient One explained that his absorbed powers were holding him back, leaving Rimuru to reckon with the need for proper cultivation.

• Rimuru decided to give Steve a chance to choose eternity, then returned to his routine at the underground base.
• Rimuru brought Steve’s two silicone models to Kamar-Taj, where Pietro angrily tried to throw them away until Wanda stopped him and asked to keep them.
• Wanda told Rimuru that her Chaos Magic was becoming more controlled under the Ancient One’s guidance, and he praised her progress.
• Rimuru warned Wanda to keep her distance from Kaecilius, explaining that he would become dangerous, and Wanda trusted his advice.
• Rimuru asked the Ancient One why he could not advance, and she said the external powers he had absorbed were mixed and impure, preventing his foundation from transforming.

Rimuru helped restore Cybertron and was asked by Optimus Prime to repair Metroplex’s damaged transformation gears. At Metroplex’s fortress, Rimuru also found Sentinel Prime living peacefully in retirement, while his search for Trypticon came up empty.

• Rimuru spent his days upgrading Transformers and watching Cybertron rebuild in his virtual dimensional planet.
• Optimus Prime told Rimuru that Metroplex’s Spark and body had been restored, but his damaged transformation gears left him stuck in base form.
• Rimuru eagerly followed Optimus Prime to Metroplex and marveled at the enormous fortress.
• Rimuru searched Cybertron for Trypticon but found no trace of him.
• Rimuru met Sentinel Prime, who explained that he had chosen to retire on the rebuilt Cybertron after the war ended.

Rimuru examined Metroplex’s badly damaged transformation gear and promised to repair it in his laboratory. When he asked for plans to build a headquarters, Optimus Prime offered him Metroplex as a mobile base, and Rimuru agreed to take him while leaving him on Cybertron for now.

• Rimuru inspected Metroplex’s cracked, jammed transformation gear and reassured Optimus Prime and Sentinel Prime that he could repair it.
• Rimuru joked about Metroplex’s carbon emissions, and Sentinel Prime and Optimus Prime explained that Cybertronians produced no exhaust during normal operation.
• Rimuru proposed taking the transformation gear to his laboratory for careful repair, and Optimus Prime entrusted the work to him.
• Rimuru asked Optimus Prime and Sentinel Prime for Titan construction plans so he could build a headquarters for his forces.
• Optimus Prime offered Rimuru Metroplex, explaining that the Titan was no longer needed on peaceful Cybertron and would otherwise remain dormant.
• Rimuru accepted Metroplex as his mobile base but decided to leave him on Cybertron until he found a suitable place for him.

Rimuru set aside the difficult repairs to Metroplex’s transformation gear and watched news reports smear Spider-Man before an alert revealed that a Life Foundation spacecraft had crashed in Malaysia after an unknown life-form breached its hull. He turned his attention to the crash, where the story left him examining the ship’s recordings and surveillance logs.

• Rimuru returned to his laboratory with Metroplex’s transformation gear and discovered that repairing its damaged runes, circuits, and Spark-linkages would take careful work.
• Rimuru put off the repairs and watched a New York news broadcast praise Spider-Man before the Daily Bugle’s coverage attacked Peter Parker as a public danger.
• Rimuru reflected on Jameson’s contradictory habit of smearing Spider-Man while protecting him from people who wanted to hurt him.
• Black Dragon alerted Rimuru that the Life Foundation’s Life One had crashed in the Borneo rainforest after an unknown life-form broke through the spacecraft’s hull.
• Rimuru stopped eating sunflower seeds and studied the spacecraft’s flight recordings, crash footage, and internal surveillance logs.

Rimuru investigated Eddie Brock’s background and went to San Francisco to meet him after the Venom Symbiote bonded with him. He found Eddie barely conscious and learned that the new host’s only immediate superhuman effect was overwhelming hunger, then offered him chocolate.

• Rimuru asked Black Dragon to gather intelligence on Eddie Brock and learned about his journalism career, failed relationship with Anne Weying, and losses after exposing the Life Foundation.
• Rimuru decided to visit San Francisco, passed through a portal, and found Eddie convulsing on the floor while Venom struggled to bond with him.
• Venom sensed Rimuru’s overwhelming power and hid inside Eddie, suppressing his presence rather than risking a confrontation.
• Eddie weakly asked Rimuru to call an ambulance, and Rimuru teased him before asking how the Symbiote had changed him.
• Eddie said he had gained no superhuman strength and felt only an intense hunger, so Rimuru offered him a chunk of special dark chocolate instead of beef.

Rimuru used chocolate to calm Venom and discovered that the Symbiote could be controlled through its appetite. He offered Venom unlimited chocolate and help overcoming its weaknesses in exchange for behaving, leaving Eddie and Venom ready to follow him.

• Eddie devoured Rimuru's special chocolate, recovering as it soothed Venom's hunger and agitation.
• Venom spoke up demanding more chocolate, then became fearful when it sensed Rimuru's overwhelming power.
• Rimuru promised Venom more chocolate and help with its weaknesses if it stopped eating people and causing trouble.
• Venom accepted Rimuru as its new master and vowed to behave, leaving Eddie stunned by its sudden change of allegiance.

Rimuru visited Eddie to explain that he was hunting Riot, a powerful Symbiote, and planned to stop Carlton Drake’s human experiments before Riot could reach him. He admitted he wanted a live Symbiote to study and improve his technology, leaving Eddie questioning the double standard.

• Eddie recognized Rimuru as a powerful Stark Industries shareholder and asked why he had come to his apartment.
• Rimuru said he was targeting Riot rather than Venom, and Venom admitted that Riot was a formidable warrior he could not defeat.
• Rimuru explained that Symbiote strength depended on compatibility with a host and wondered why Eddie and Venom performed so poorly in fights.
• Rimuru said he could not track Riot’s route from Malaysia and decided to target Carlton Drake, whose human experiments made him Riot’s intended host.
• Rimuru revealed that he wanted a live Symbiote to study for his technology, prompting Eddie to question how that differed from Drake’s experiments.

Eddie challenged Rimuru over the ethics of using Symbiotes for research, but Rimuru explained why targeting the murderous Riot differed from Drake’s experiments on innocent people. Rimuru then sent Eddie’s evidence to Nick Fury, who ordered the Life Foundation’s San Francisco headquarters sealed and authorized lethal force against Carlton Drake if he resisted or fled.

• Eddie accused Rimuru of applying a double standard by condemning Drake’s experiments on people while planning to experiment on Symbiotes.
• Rimuru argued that Drake had tortured innocent humans, while he intended to use the murderous Riot as research material; Eddie accepted the distinction, and Venom agreed that Riot was the bad one.
• Eddie asked whether they should raid the Life Foundation or expose its crimes, and Rimuru instead requested the evidence Eddie had gathered undercover.
• Rimuru had Black Dragon Gillvalis archive and transmit Eddie’s photos and recordings to Nick Fury, then warned him that dangerous Symbiotes had reached Earth.
• After reviewing the evidence and footage of Venom, Nick Fury ordered a task force to seal off the Life Foundation’s San Francisco headquarters and authorized them to shoot Carlton Drake if he resisted, fought back, or fled.

Rimuru cut short Fury’s excuses about returning the 2,000 T-1000s after learning that his automated electric car factory had finally been approved. He offered Eddie a million-dollar job promoting the cars, then tasked Venom with luring Riot into a trap.

• Fury dodged Rimuru’s demand to return the 2,000 T-1000s by citing S.H.I.E.L.D.’s staffing pressures and announcing approval for Rimuru’s car factory.
• Eddie secretly took notes on Rimuru and Fury’s conversation, then learned he had been blacklisted as a journalist and would be monitored by S.H.I.E.L.D.
• Rimuru offered Eddie a million-dollar annual salary and benefits to promote the electric cars, and Eddie eagerly accepted.
• Rimuru explained the danger of Venom forming a Codex and attracting Knull, and decided to keep Eddie and Venom close.
• Rimuru ordered Venom to use the Symbiotes’ telepathic link to lure Riot into a trap, promising Venom unlimited magic chocolate.

Rimuru forced Riot toward a trap by announcing an accelerated spacecraft launch, then celebrated the approval and unveiling of his futuristic electric car. Tony Stark watched the launch and tried to revive his father’s hover-car project, but found it could not work on ordinary roads.

• Rimuru told Nick Fury to conceal Drake’s arrest and announce an early spacecraft launch to lure Riot into revealing itself.
• Rimuru celebrated the approval of his electric-car technology and unveiled a futuristic mass-produced vehicle at a global press conference.
• The press compared Rimuru to Howard Stark, prompting Tony Stark to resent being overlooked and decide to finish his father’s hover-car project.
• Tony examined the hover-car blueprints and concluded that electromagnetic levitation required magnetic roads while jet propulsion would destroy ordinary roads.

Tony's attempts to solve the hovercar problem failed, so he asked Rimuru for antigravity principles. Rimuru produced a Cybertronian levitation craft and data, leaving Tony shocked by the Transformers' technological level.

• Tony's simulations showed that electromagnetic and jet-propelled levitation were impractical for civilian use, reminding him of Howard Stark's unfinished hovercar dream.
• Tony decided to ask Rimuru for antigravity formulas so he could adapt and implement the technology himself.
• Rimuru realized he lacked Earth's antigravity formulas but could access Cybertronian levitation technology through Black Dragon.
• Rimuru retrieved Cybertronian levitation data and brought out a hovering reconnaissance craft for Tony to inspect.
• Tony recognized the craft as Transformers technology and realized how far their engineering surpassed Earth's.
