Tamaki Amajiki, alias the hero Suneater, attends U.A. High School as one of Class 3-A's elite "Big Three." He graduates after the Final War, becoming professional hero Fat Gum's sidekick. Eight years later, he achieves the rank of No. 18 Pro Hero. Standing 177 cm (5'9"), Tamaki possesses pale skin, pointed elf-like ears, and messy dark indigo hair protruding behind his head. His thin eyes often appear tired and partially hidden by his bangs. He typically hunches his shoulders and avoids direct eye contact. Post-Final War, he shortens his hair significantly. His school uniform is worn loosely with an untucked shirt and loosened tie. His initial hero costume comprises a black bodysuit with beige arm/shoulder plating, a white tunic, a matching hooded cape, a beige face mask featuring a purple lens, and a purple utility vest holding food pouches. He fights barefoot for mobility. His updated costume retains the core design but features white wrist armor, dark green pouches, and a scarlet tunic, hood, and face mask. The hood incorporates jaw-like spikes and a straw-like cheek protrusion for rapid food consumption. Extremely shy, introverted, and socially anxious, Tamaki battles persistent self-doubt despite his formidable abilities. Overwhelmed, he often presses his face against walls and interprets praise as mockery, his perfectionism eroding his self-esteem. His inherent pessimism contrasts sharply with mentor Fat Gum's optimism. Yet, critical moments trigger unexpected bravery fueled by fierce loyalty and a powerful sense of justice. He voices firm convictions, especially against dismissing others' hard work, inspired by his close bond with Mirio Togata. Tamaki deeply values camaraderie and rejects treating allies as expendable. His anxiety roots in creator Kohei Horikoshi's experiences, including attending a crowded Jump Festa and childhood school transfers. Tamaki's Quirk, Manifest, enables him to manifest physical traits of anything he consumes—octopus tentacles from takoyaki or crystalline armor from ingesting crystals. Manifested traits depend on quantity consumed and remain accessible only during digestion, making daily meal planning crucial. Through rigorous training, he manifests multiple traits simultaneously, controls their size, and strategically combines features for tactical advantage. His combat style emphasizes versatility: clams for defense, octopus for offense. Emergency rations are stored in his costume pouches. He possesses exceptional tactical intellect. During the Shie Hassaikai raid, he single-handedly disabled three Yakuza members—Toya Setsuno, Yu Hojo, and Soramitsu Tabe—recognizing their strategy to stall heroes for Overhaul's escape. He adapted mid-battle by exploiting weaknesses: obscuring Toya's vision to neutralize his object-stealing Quirk and turning Yu's crystals against him. He later confiscated their masks after spotting hidden weapons. In the Final War, he joined the assault on Tomura Shigaraki, holding his ground alongside the Big Three. His Ultimate Moves, named after mythical creatures, include: - Kraken: Giant tentacles for area attacks. - Centaur: Equine lower body launching vine-wrapped fruit projectiles. - Octopus Mirage: Camouflage enabling stealth strikes. - Scorpius Toxin: Venom-injecting scorpion tails. - Plasma Cannon: A combined energy blast with Nejire Hado, fusing traits from multiple organisms. His stats are Power: A, Technique: S, Wits: A, Communication: E. Frequent childhood school transfers marked Tamaki's youth. In third grade, he struggled socially until Mirio Togata befriended him over a shared hero interest. Their bond solidified during middle school Quirk training sessions where both initially faltered—Tamaki manifested only a small plant due to nerves. Mirio's relentless optimism helped Tamaki persist despite insecurities. They entered U.A. High together, later forming the Big Three with Nejire Hado after Tamaki awkwardly initiated a hero conversation. His hero name, Suneater, reflects Mirio's encouragement to "outshine the sun." Key developments include his Fat Gum internship where he mentored Eijiro Kirishima. On patrol, he neutralized a thug using octopus and clam manifestations but took a Quirk-destroying bullet. Kirishima shielded him from a second shot, though Tamaki's Quirk factor temporarily deteriorated. Full recovery followed, and the incident yielded vital evidence on Overhaul's bullets. During the Shie Hassaikai raid, he conquered anxiety to protect allies, solidifying his resolve to honor their faith. His growth culminates in a successful pro hero career, retaining his reserved nature while attaining high rank. Additional details: Birthday March 4, AB blood type (associated in Japanese culture with rationality and aloofness), fondness for butterflies. His Quirk embodies "you are what you eat." The kanji in Amajiki (天喰) mean "sky" and "eat"; Tamaki (環) means "ring." He shares a birthday with Endeavor's driver, Untenmaru Kurumada.
