Equality 7-2521
A man who has always been too curious and too intelligent for his peers and his society, he finds a secret tunnel where he conducts scientific experiments and rediscovers electricity. He tries to show the World Council of Scholars his electrical invention, but he is forced to run away from the City and is joined by Liberty 5-3000, whom he loves and who calls him "the Unconquered." In the process, he realizes the dangers of collectivism and, upon learning the word "I," renames himself "Prometheus."
Council of Vocations
Three males and two females with white hair and cracked faces who assign Equality 7-2521 the job of Street Sweeper after he leaves the Home of the Scholars.
Union 5-3992
A pale, stupid, and sickly boy who suffers from seizures. When Equality 7-2521 is younger, he tries unsuccessfully to imitate Union 5-3992's dullness, and when the two are older they work in a brigade of Street Sweepers with International 4-8818. Union 5-3992 is too slow to understand Equality 7-2521's contact with Liberty 5-3000.
International 4-8818
A friend of Equality 7-2521, he is a fellow Street Sweeper and has laughter in his eyes. He is too afraid to break the law and join his friend in exploring the secret tunnel, but he is loyal and does not betray Equality 7-2521 and tell the authorities about his friend's use of the tunnel or contact with Liberty 5-3000.
Liberty 5-3000
Referred to by Equality 7-2521 as the Golden One, she is one of the Peasants who till the land outside of the city, but unlike the other women she is tall, beautiful, and proud.

The Transgressor
Also called the Saint of the pyre by Equality 7-2521, he speaks the Unspeakable Word "I" and is burned at the stake. He goes to his death proudly and calmly, and as he dies, he looks at Equality 7-2521 as if to ask Equality 7-2521 to find the Unspeakable Word and be his heir.
