Tetsuo Shima
The primary adversary in the AKIRA series is Tetsuo Shima. He is a metaphor for the devastating potential of power in the hands of bad people. His personality drastically changes after gaining the abilities of the Espers and surviving their attempt to murder him. He rushes through Neo Tokyo in search of Akira while carelessly using his psychic abilities to hurt both the military and innocent bystanders.
He is sent to a military facility following a collision with the Esper Takashi. Here, he starts to manifest latent, potent psychic skills comparable to those of Akira, the person who caused ancient Tokyo to experience a psychic explosion years earlier. In addition to conferring devastatingly destructive abilities, these capabilities also produce excruciatingly severe headaches as they grow.
Tetsuo Shima teases and attacks Kaneda after this rampage to stroke his own ego. Despite the way he treats Kaneda and his expressions of contempt, he shows true fear when his body starts to grow out of control despite the fact that he and Kaneda were unable to stop the mutation. The main focus of the film is unquestionably Tetsuo's mental breakdown as he becomes an esper with supernatural abilities. He develops into one of the most powerful anime characters of all time due to the fact that he eventually creates his own universe.
