Personality[]
Monster Cat doesn't seem to be any different from an ordinary cat, appearing simple and docile under normal circumstances. While injected with Trigger, however, it became violent and erratic due to the effects of the drug. Even then, however, it still appeared to retain some of its nature as a cat, as Knuckleduster was able to distract and redirect it with a makeshift cat toy,[1] and it also chased after Koichi Haimawari after mistaking his All Might hoodie antennae for a toy.[2]
Synopsis[]
Vs. Queen Bee Arc[]
Monster Cat merges with a bus.
Monster Cat first appeared during a sightseeing trip in Tokyo, when Koichi was accompanying his mother Shoko and friend Makoto Tsukauchi. As they prepared to return home by bus, the stray cat boarded the vehicle and was unexpectedly injected with Trigger by one of Kuin Hachisuka's bees. The drug activated and amplified the cat's Quirk, allowing it to fuse with the bus and transform into a sentient, animalized vehicle. This fusion turned the cat into a dangerous living bus, soon dubbed Monster Cat, which began to swerve uncontrollably through Tokyo's streets.
Knuckleduster, observing from a rooftop, initially dismissed the incident, believing it unrelated to his hunt for Trigger dealers. However, upon spotting Koichi aboard the rogue vehicle, he intervened by constructing a makeshift cat toy consisting of a feather duster and duct tape obtained from Pop☆Step to lure the creature onto the expressway, averting a potential crash into a crowded shopping district.
Monster Cat attacks Team Idaten's truck.
As the situation escalated, Pro Hero Ingenium arrived and boarded the bus to assess the danger. Though he identified Koichi among the passengers, he kept their connection secret. With the bus uncontrollable and heading toward a ruined overpass, damaged earlier by Ryuichi Gojiyama, the urgency grew.
Team Idaten arrived with a truck to transfer the passengers to safety. Enigma, using her Gigantification Quirk, began evacuating people safely, including Koichi and Shoko. However, Kuin, monitoring the situation remotely, injected Monster Cat with an additional dose of Trigger, driving it berserk. The cat lashed out at Team Idaten's vehicle, disabling it and knocking the bus driver and tour guide out of the bus. Ingenium rescued them, but Makoto was left aboard alone.[1]
Monster Cat chases after The Crawler.
Running low on fuel, Ingenium required assistance. Koichi, now in his vigilante persona, The Crawler, defied his mother's pleas and raced to deliver grapefruit juice to refuel Ingenium's Engine Quirk. Together, they attempted a final rescue. The Crawler distracted the creature while Ingenium prepared to extract Makoto, but Monster Cat mistook Koichi's All Might hoodie antennae for a toy and pounced.
Forced to act, Ingenium used his Ultimate Move, Recipro Burst, to intercept the creature and protect The Crawler, though the maneuver overheated his Quirk. As the bus neared the broken overpass, The Crawler accelerated after it, unmasking himself in the process and leaping aboard to save Makoto. The bus then plunged off the edge.
Kuin takes Monster Cat with her.
During the free fall, Koichi, driven by sheer willpower, unlocked a new ability within his Slide and Glide Quirk, allowing him to momentarily repel himself through the air and achieve a form of temporary flight. This miraculous move allowed him to reach Ingenium, who helped carry Makoto the final distance to safety. Koichi landed roughly but unharmed, giving a triumphant thumbs-up.
In the aftermath, all passengers were confirmed safe. Kuin left the scene with Monster Cat in tow, the living vehicle having survived the fall. Later, Koichi attempted to replicate his midair jump but was only able to achieve a 30 cm hover. He described the feat as a "double jump" and speculated it may have been a one-time, adrenaline-induced event.[2]
