Hourman (spelled Hour-Man in his earliest appearances) is the name of three different fictional DC Comics superheroes the first of whom was created by Ken Fitch and Bernard Baily in Adventure Comics #48 (April 1940), during the Golden Age of Comic Books.
The third Hourman, the Hourman of the 853rd century, is an android (though he describes himself as an \"intelligent machine colony\") constructed by Tyler Chemorobotics (formerly TylerCo). Although he is an android, he possesses the full range of emotions and human flaws that an ordinary human does. Nonetheless, the technology with which he was constructed is far advanced beyond anything conceivable in the 20th century.
Why the android was built is unknown, although it seems likely that he was in fact commissioned by the New God Metron, who sought to make it his replacement and apprentice. Rex Tyler (the original Hourman), who served as the biological template for the android, spent some time in the future and was involved in its construction.
Hourman often perceives himself as Rex and also as Rex\'s descendant. Originally possessing the time-manipulating cosmic artifact known as the Worlogog, he divested himself of most of its power at the suggestion of Snapper Carr and went about learning to be human. After failing to stop a villain from escaping a fight, Hourman quit the JSA and began travelling through the timestream, returning when he received a distress call from the JSA.
