Why does Tetsuo say "I am Tetsuo" at the end of Akira? At the end of Akira, there is a massive power release; then:


   Tetsuo manages to gain full control over his powers, and these abilities end up creating a new Big Bang in another dimension.


After this event, Tetsuo says the following: "I am Tetsuo."



Why did he say this? What meaning does it have?
Testuo (probably like Akira before him) finally gains full control of his powers, and uses it to initiate the creation of a new universe. In effect he is now the creator god of this new universe, and he proclaims this at the end:

"I am Tetsuo"

This is the real Tetsuo, he is saying. His essence without the limiting shell of his mortal body. The pure energy of his being distilled into a pocket universe.
