[Samurai Jack] Why doesn't Jack use his real name?
gpt
Jack's true name is his most prized-possession, surpassing even his sword. For most of his life his name was the only thing he had connecting him to a father and a nation he had left behind. His name is his honor.

After years of training, victory is snatched from him and he is sent to a future where he failed. The future is a constant reminder of his failure and inability to save his home, and prevent Aku from doing the same thing to everyone else in the world.

He does not deserve his name, in his own eyes. He will only reclaim it once more when he becomes the hero his father always knew him to be.
