Akira

AKIRA, the child psychic, is the husk of a child that the manga and film takes its name from. Akira is aprt of the program tha awakened the psychic powers inchildren, and he was the most powerful of all the children. His powers were so great that they erased his personality and Akira simply became a channel for the powers inside him. The reason is unknown how Akira first destroyed Neo-tokyo in a nuclear blast, but it happened the second time due to Takashi (Akiras friend from the program) getting shot in the head by Mr Nezu, the resistance's leader. Takashi, Akira and the other children from the program had a psychic connection with each other and the pain of Takashi dying caused Akira to release is energies again. Kaneda and Kei survived the blast, as did many others, but most of the citizens of Neo-Tokyo perished and the city itself was destroyed. When Tetsuos powers grew to the same level as Akiras, he was wounded and began to create a nuclear explosion equal to Akiras. Akira was also psychically linked to Tetsuo and for a brief amount of time, his true personaliy surfaced. Akira was able to cancel out Tetsuo's explosion, in doing so he killed Tetsuo and he himself died.
