Fat Absorption: Taishiro's Quirk allows him to make anything adhere to his obese body on contact and sink into his body fat. His fat can also store kinetic energy, which he can convert into offensive muscle at the cost of his fat, thus weakening his defense.
Fataxi: Taishiro can use his Quirk to hold anyone smaller than him within his body as passengers. He uses this move to escort his allies in or out of battles.
Enhanced Strength: Taishiro is shown to have incredible strength, as he can grab hold of multiple villain mechs and keep them in his grip while using his Quirk. He can also crush two pieces of hard candy with his bare hand.
Enhanced Durability: Taishiro has excellent durability thanks to the amount of fat he has compiled. He can take several assaults from Kendo Rappa's powerful bullet punches and keep standing, whereas Eijiro's "Unbreakable" Ultimate Move was barely able to defend against one of Kendo's punches.
Enhanced Speed: Despite his stature, Taishiro's speed is rather impressive, as he can react quickly against troubling situations.
Enhanced Stamina: Despite being highly injured, Taishiro continued to battle Kendo Rappa, showing incredible stamina when even the powerful Ejiro Kirishima could not stand after just one barrage of punches.
Keen Intellect: Taishiro possesses a very keen intellect and analytical mind. After witnessing the Quirks of Kendo and Hekiji, Taishiro realized the duo was not on the Quirk roster for the Shie Hassaikai Raid Team and that battling the pair would be difficult. Following his second endurance of Kendo's bullet punches, Taishiro surmised that getting in close doesn't give the BMI Hero a chance to dodge the assault, and due to the amount of strength behind the brawler's attacks, Taishiro's Fat Absorption couldn't absorb all of the damage. With his deductions, Taishiro concluded that Kendo would wear him down until the hero was out of sight. And, despite the bickering he noticed between Kendo and Hekiji, Taishiro knew that Hekiji would still produce a barrier if Kendo needed it, rendering the defeat of the Yakuza dyad near impossible with Hekiji still standing. Withstanding Kendo's onslaught a third time, Taishiro noticed that the Eight Bullets member's punches were getting faster, and each blow was stronger than the last, making the obese hero question whether he could hold out against Kendo as long as he intended. In the aftermath of the battle, Kendo could rise to his feet, making Taishiro deduce that Hekiji's barrier had cushioned his energy-stockpiled attack. When Kendo told the battle-worn BMI Hero there was a medical supplies room that he and the present heroes could use to treat their injuries, Taishiro, taking note of the candidness of the brawler's words, understood that Kendo wasn't leading him and Eijiro into a trap, as he skeptically believed was the case at first.
Police Intuition: Taishiro is a successful hero with extensive experience working alongside Japan's Police Force, granting him a greater understanding of both police body functions and protocol compared to the average Pro Hero. This intuition is shown by how Taishiro was able to understand complex drug trafficking networks and forensics by how he collected a prototype Quirk-Destroying Drug for testing, making him a significant asset to the Nighteye Agency's investigation and raid of the Shie Hassaikai.
