Tamaki is a tall young man with rather pale skin. His ears are longer than most, their tips pointy and somewhat elf-like. He has messy, indigo hair, which sticks out behind his head, and thin, tired-looking eyes, partially covered by his bangs. Tamaki's shoulders are usually hunched, and he avoids eye contact with people. Tamaki is extremely shy, aloof, depressed, "intimidating", and introverted, especially around big audiences. He gets nervous very easily when talking to other people. If his anxiety gets the best of him, Tamaki will often face away and lean into a wall to hide his face from others. This also happens whenever Tamaki has a bad feeling or feels insulted. While his physical abilities and Quirk are outstanding, Tamaki is socially awkward and lacks confidence in his powers. He feels overwhelmed by the pressure to be perfect, which has damaged his self-esteem. Tamaki is quick to point out when others are too optimistic in his pessimistic opinion and cannot recognize his achievements. His pessimism directly contrasts with Fat Gum's optimism. Even after being complimented by Fat Gum, Tamaki often takes his mentor's praise for taunting. Despite his timid heart, Tamaki can show flashes of bravery. Even though he's always been a shy and reserved boy, Tamaki was able to hone his skills and climb the ranks into one of U.A.'s Big 3. Mirio Togata is a big inspiration for Tamaki, and their cooperation throughout their lives has led him to establish his own set of stern beliefs that he will uphold and vocalize. Tamaki has mastered his Quirk, Manifest, through vigorous training. He can manipulate feature selection, size manipulation, and simultaneous manifestations. This multifaceted aspect gives Tamaki's fighting style incredible variation and unpredictability. Tamaki eats plenty of Takoyaki and Clams daily because he believes they're great for offense and defense. For example, Tamaki often uses tentacle fingers to bind his opponents while using a clamshell husk for protection. Tamaki has a variety of other powerful combinations as well, including using chicken talon strengthened with octopus muscles or tentacle fingers reinforced by crab shells.
