Class 1-A is anchored by i(Deku), a once-Quirkless underdog whose innate bravery earns him the legendary stockpiling power One For All. He evolves into a tactical leader by utilizing "Full Cowling" to protect his body from breaking and unlocking six past vestiges' Quirks, including Blackwhip and Gearshift, all while supported by his mentor All Might and his romantic anchor, Ochaco Uraraka. His childhood friend and fierce rival is Katsuki Bakugo

a volatile combat prodigy with an intense superiority complex. He secretes nitroglycerin sweat to trigger powerful Explosions, mastering high-speed aerial maneuvers like "Howitzer Impact" and "Cluster" while undergoing a profound humbling arc that shifts his focus from pure domination to saving others, cementing a deep, loyal best-friendship with Eijiro Kirishima.

(Shoto) enters as an elite but emotionally damaged student bred through an abusive Quirk marriage to surpass All Might. He initially rejects his father Endeavor’s fire side, but after Izuku helps him heal, he embraces his dual Half-Cold Half-Hot Quirk—later mastering "Phosphor" to blend fire and ice into a stable energy—while navigating family reconciliation and a bitter battle against his villainous brother, Dabi.

(Ingenium) is the hyper-formal class representative whose rigid worldview shatters when his brother is paralyzed by the Hero Killer Stain. Overcoming blind vengeance, he inherits the Ingenium mantle, utilizing his calf-based Engine Quirk—which runs on orange juice and can be upgraded by ripping out his exhaust pipes—to unlock the blistering speed of "Recipro Turbo" and act as a fiercely unifying protector for his friends.

(Froppy) acts as the class’s reliable emotional rock and blunt moral compass, having matured quickly from single-handedly raising her younger siblings. Her Frog Quirk grants her wall-climbing abilities, high jumping, camouflage, and a 20-meter prehensile tongue strike, though she is highly vulnerable to involuntary hibernation in extreme cold

(Red Riot) masks deep personal insecurities about his defensive abilities behind a loud passion for chivalry and "manliness." Inspired by the retro hero Crimson Riot, he shatters his psychological limits during the Shie Hassaikai raid, pushing his Hardening Quirk into "Red Riot Unbreakable" to turn his skin into a temporarily invulnerable, jagged shield that can block bullets and protect civilians

(Creati) is a recommended elite who suffers a severe crisis of self-confidence and imposter syndrome after early combat defeats. She overcomes this to become the class’s top tactical commander, using her Creation Quirk to break down body lipids and materialize any non-living object from her skin, a process that demands an exhaustive, encyclopedic understanding of an item's molecular and chemical structures.

(Uravity) is a deeply empathetic hero who shifts her initial practical goal of financially supporting her parents into a grander philosophy focused on protecting other heroes. Her Zero Gravity Quirk allows her to float objects via her fingertips, a power she combines with Gunhead Martial Arts for close-quarters combat while suppressing her romantic feelings for Izuku and forming a tragic psychological connection with the villain Himiko Toga

(Chargebolt) is the energetic social butterfly of the group who initially fears being a liability due to his Electrification Quirk, which releases massive high-voltage electricity but short-circuits his brain into a dazed state if he exceeds his limit. He matures into a heroic frontline defender, using support gear to aim precise linear shots and absorbing massive electrical hazards to shield his vanguard teammates

(Tsukuyomi) is a disciplined, gothic fighter who speaks in archaic phrases and harbors immense raw potential. Under the fast-paced mentorship of the No. 2 Pro Hero Hawks, he learns to command Dark Shadow, a sentient shadow monster that is weak but docile in bright light, but gains god-like, feral destructive power in total darkness, eventually unlocking high-speed flight via the "Black Fallen Angel" technique.
