Tamaki Amajiki, known as the hero Suneater, appears briefly in *My Hero Academia: World Heroes' Mission* as part of the wider hero response to the global crisis. A student at U.A. High School, he belongs to "The Big Three," recognized for their exceptional combat abilities. His Quirk, "Manifest," allows him to physically manifest characteristics of any food he consumes. Eating takoyaki grants octopus tentacles, while clams generate protective shells. The strength and versatility of these manifestations depend on the quantity and type of food ingested, requiring daily replenishment. Tamaki struggles with severe social anxiety and self-doubt, often interpreting praise as mockery and retreating physically when overwhelmed. Yet he demonstrates remarkable bravery in critical moments. His resolve stems largely from his childhood friendship with Mirio Togata. After transferring schools in third grade, Tamaki failed to integrate until Mirio approached him over their shared admiration for heroes. This bond became foundational; Mirio's unwavering optimism counterbalances Tamaki's pessimism. Tamaki later chose the hero name "Suneater" to honor Mirio's declaration that he would "outshine the sun." His combat prowess is highlighted during the Shie Hassaikai Arc, where he single-handedly defeats three members of the Eight Bullets. This battle showcases his tactical intellect: he disarms opponents swiftly, exploits their Quirk limitations, and utilizes absorbed traits, like crystal defense from Yu Hojo's Quirk, to control the fight. Pro Hero Fat Gum states Tamaki surpasses most professional heroes in skill. Training enables Tamaki to manipulate multiple manifestations simultaneously, control their size, and select optimal traits. Key techniques include **Chimera Kraken** (giant tentacles for area attacks), **Chimera Centaur** (horse lower body with vine arms for multi-target strikes), and the **Plasma Cannon** (a combined energy blast with Nejire Hado, fusing traits from over a dozen organisms). His strategic approach involves pre-planning his diet—prioritizing clams for defense and takoyaki for offense—and carrying emergency rations in costume pouches. Tamaki's growth centers on confronting his anxieties through duty. During the Shie Hassaikai raid, he initially freezes under pressure but later volunteers to fight alone to protect allies, declaring that others' faith "makes me stronger." This shift underscores his journey from self-doubt to relying on camaraderie as a source of strength. His core belief—that hard work must never be undermined—drives his willingness to vocalize convictions, as seen when defending Mirio's efforts to Class 1-A. Following the Final War, Tamaki graduates from U.A. and becomes a Pro Hero ranked No. 18. He serves as Fat Gum's sidekick, adopting a redesigned scarlet costume with a straw-like apparatus for quick food consumption during missions.
