Monarch is the name of three fictional DC Comics supervillain. The first Monarch is Hank Hall, formerly Hawk, who later renames himself Extant for the Zero Hour crossover. The second Monarch is Nathaniel Adam, a U.S. Army Captain. The third Monarch is Captain Atom, a former superhero retroactively revealed to be a "quantum field" duplicate of Nathaniel Adam. Monarch was created by Archie Goodwin, Denny O'Neil, and Dan Jurgens, and first appeared in Armageddon 2001 #1, cover dated October (1991).

Monarch is an oppressive tyrant from a bleak, dystopia Earth in the year 2030 AD. The people are unhappy with his rule, particularly a scientist named Matthew Ryder, an expert on temporal studies, who is convinced he can use his technology to travel back in time and prevent the maniacal ruler from ever coming to power. He learns that, in 1991, one of Earth's heroes eventually turned evil and became Monarch, who would conquer the world ten years later.

Chosen by Monarch to take part in a time-travel experiment, Matthew Ryder travels back to the DC Universe of 1991. Ryder decides to find out who Monarch really was and, if possible, kill him before he can rise to power. As he travels through the rift, his body mutates into a form of living temporal energy, and upon arriving at his destination, he takes the name Waverider.

Although Waverider uses his abilities to look into the future of various characters, he cannot pinpoint who will become Monarch. But eventually, Waverider accidentally comes into physical contact with Captain Atom, unleashing a storm of temporal energy that opens a gate to the future through which Monarch emerges. Monarch, it seems, has been monitoring Waverider's every move in the past ever since he left the future, and merely waiting for the perfect time to travel back and stop Waverider from erasing Monarch from existence.
