All Might

In his muscular form, All Might is a very tall, blond man whose design resembles classic American comic book heroes. His hair is combed back except for two spiky front strands. His hero costume consists of a red, white, and blue bodysuit with yellow boots. He has been shown both with and without a cape.

However, in his original form, he is an excessively thin man who coughs up large amounts of blood when he speaks. His blond hair appears disheveled and unruly, with two strands framing his bony face. In this form, his clothes appear baggy, as he wears larger sizes for practical purposes (in case he needs to transform into his muscular form). In both forms, his eyes appear shadowed (as if they were dark circles), but the difference is that his blue pupils are visible in his original form, and on a couple of occasions in his muscular form, as a symbolic display of pride after a particularly difficult battle.

His personality as All Might largely derives from American hero stereotypes, having dramatic entrances and dialogues during fights. Due to his popularity and the importance of his role as a symbol of peace, he is always shown to be kind, joking, and friendly, enjoying the attention that his position gives him.

However, when he reverts to his original form, he tends to be less energetic due to the permanent wound in his abdomen and the large amount of energy his muscular form requires. In this state, he tries to keep a low profile and avoids drawing attention to himself, as he firmly believes that to preserve the legacy of "All Might" as a symbol of peace and maintain social order, his original condition and health status must remain a secret. He is shown to be very friendly and empathetic, helping Shiro on several occasions.

Quirk and Abilities

One For All: Inherited from Shimura Nana. All Might's quirk grants him great endurance, much greater agility, strength, and the ability to jump great distances, so much so that it seems he can fly.

Skills
Immense strength: Toshinori's Detroit Smash is capable not only of defeating a villain, but also of changing the weather shortly afterward. He is capable of causing collateral damage to an entire city block with a single punch.
Immense Speed: In conjunction with his immense physical strength, Toshinori possesses an equally impressive amount of speed. He attacked Gond without him noticing and even managed to save Shiro just as Gond was about to kill him.
Immense Durability: Toshinori possesses extreme durability. He demonstrated his ability to withstand all of Gond's attacks, only weakening due to the time remaining in his transformation.
Ability to "fly": Toshinori demonstrated this ability. He can jump to an extremely high height and speed, to the point of appearing as if he is actually flying.
