Personality: Despite his frightening appearance, Mezo is friendly and gentle and will work nicely with anyone. He is not the type to hold grudges, showing no ill will towards those that harm him unwillingly. Mezo is entirely selfless and willing to risk his life for anyone. He can be empathetic and understanding but still shows a sense of maturity and responsibility that prevents him from acting under emotional impulses, even if he feels regretful. He is very protective of his classmates, especially if they are hurt or injured. Mezo claims to hold no desire for material needs, being okay with having few possessions of his own, and this is a trait he has been carrying since childhood. Mezo is also quite thick-skinned, as he said he was used to being feared and seemed unfazed when Pony Tsunotori called him an octopus and said she didn't like to look at him. In Mezo's hometown, there is still prejudice against those whose bodies are altered outwardly by their Quirks, and people are often frightened of him. He started wearing his signature mask because his face made a young girl cry, and he didn't want to cause any sadness.[5] He also states that his facial scars and the fact that he is a heteromorph can make people assume that he became a hero to enact vengeance on the people who scarred him, which is not true. Part of his motivation to be a hero is to tear down the societal walls that have stood in the way of heteromorphs like himself for over a century. However, he also knows that he can't do so in a single generation, and as such, he has a marked distaste for shortsightedness regarding the use of force and violence to head such a change in society. Abilities: Enhanced Strength: Mezo possesses a high degree of physical strength, as he could exert as much as 540 kilograms (1,188 pounds) of force during the Quirk Apprehension Test. Enhanced Speed: Despite his size and muscular physique, Mezo possesses impressive speed. Enhanced Stamina: Mezo also has an incredible supply of endurance. Enhanced Durability: Mezo has been shown to withstand significant damage. Enhanced Reflexes: Mezo has extremely good reflexes. Keen Intellect: Mezo is known to be quite intelligent, scoring 10th place in the midterms, displaying his skill in academics. He is also very analytical. Appearance: Mezo is a tall, muscular young man with pale gray hair swept forwards, covering most of his face, and bent downwards at almost a right angle over his eye. He has six arms attached by a web of skin; the arms are very physically strong, and while his Quirk is not in use, only the front two arms have hands, the rest ending in thin stumps. He has a slightly elongated face; his eyes set more towards the sides, the majority of which, due to his scars, he has always kept hidden by a light blue mask, which covers him from just below his eyes to the base of his neck. He is rarely seen without it, as he doesn't appear when the other students are bathing in the hot springs, and he wears it with every outfit. Although he has no discernible ears, he doesn't have to use his Quirk to hear. At U.A., he wears the standard male uniform: a light gray blazer with dark turquoise trimmings over a white dress shirt, dark blue-green dress pants, a red tie, and plain brown shoes, with the only notable difference is that the blazer is sleeveless to make room for his six tentacles. His Hero Costume consists of a tight light blue tank top, with six white markings resembling eyes, connected at the top to a darker, more indigo-colored mask, similar to the one he usually wears, only with three light blue indents on the back (yellow in the manga). He has a belt with another, larger yellow eye shape embedded into its center, below which he wears slightly baggy trousers to match his shirt, two darker lines running down the sides of his legs, and indigo boots. After his mask was torn during his fight with Spinner, alongside many rioting civilians during the Final War, he is revealed to have an elongated face without a nose, as well as an extended mouth with large teeth and prominent scars around his lips, one running from the back, downwards towards his neck. Eight years after the end of the Final War, Mezo has grown huge, taller, more bulker arms, and he wears a ponytail at the back of his head with a few strands sticking out, along with not wearing his mask outside of his costume. His costume remains mostly the same, with the light blue colors being lighter and the dark blue being paler, the large yellow eye being omitted on his belt with a pouch on the back of it, the lines on the side are now of a circular pattern in light and dark blue, and a dark purple line over the top of his mask.
