Brau 1589

The first robot in history to kill a human. One of the key figures in the story. He is isolated and imprisoned underground in a state of immobility at the Artificial Intelligence Correction Camp in Brussels, Euro Federation, Belgium. A thorough investigation of his artificial brain was conducted, but the conclusion was "normal." Humans, fearful of the possibility that a robot with a normal artificial brain could commit "murder," are wary of him, and there are few who understand him. The few who do understand him are Dr. Tenma and Atom.

He has been destroyed to the point where his wiring is barely connected, leaning against a wall, and immobilized with multiple weapons. Although he is in a state of decay with his frame exposed, he is conscious. He emits such powerful electromagnetic waves that he causes malfunctions unless a protector is worn, and he has destroyed four robots that have come to visit him so far.

Upon their first meeting, Gesicht saw through him as a fellow "murderer" and offered to exchange memory chips. He provided Gesicht with clues to solve the serial robot destruction incidents, suggesting that the targets were the seven most advanced robots in the world, hinting at the presence of Dr. Roosevelt behind the President of the United States of Thracia, and implying that he was the true mastermind. He speculated that the horns on the corpses were a symbol of "Pluto," the god of death. He expressed his act of murder as "execution." After the deaths of the seven robots, including Atom, Dr. Tenma visited him, considering him the only remaining being with an evolved artificial brain, along with Brau (and Goji, who impersonates Abullah, Dr. Roosevelt).

He had a past connection with Atom and was an old acquaintance. Understanding that Atom, being a robot, should not be able to grow, he noticed the "evolution" of his inner self, remarking that he seemed "a bit more mature." He also sensed the "warmth" that suggested a genuine heart had developed within Atom. Realizing that Atom was risking his life to stop Bora, he promised to meet again.

A spear is pierced into Brau 1589's body. It was said that if it were removed, Brau would die, but that was a "lie."

In the epilogue, he receives a request from Atom. After the Earth is saved by Pluto, he escapes and goes to Alexander and Roosevelt, intending to execute them with the spear he pulled out himself, but he finds a heart within Alexander and releases only him.
