All Might's hero persona appears to be derived from western superhero stereotypes. His personality is very colorful and tends to have a lot of dramatic flair. Always sporting a giant smile, All Might usually show off a bright, borderline obnoxious, can-do attitude to inspire others. He tends to be extremely friendly and amicable, due to his popularity and years in the spotlight. However, when he reverts to his sick and scrawny form, he tends to be less energetic. He loses the need to hide his worries about the state of affairs around him behind his smile. Additionally, he avoids drawing attention to himself altogether, afraid that others might learn of his current state of health.
