Mick Rory first appeared in The Flash and then became a member of The Legends Of Tomorrow. Here are some things about his comic version.

Dominic Purcell has portrayed Mick Rory, also known as Heat Wave, in the character's first live-action adaptation since his introduction on season one of The Flash, alongside his classic villainous partner, Wentworth Miller's Leonard Snart, aka Captain Cold. Known on The Flash as the two founding members of "The Rogues," both of these characters went on to appear in the Arrowverse's Legends of Tomorrow spin-off.

While Leonard Snart sacrificed himself at the end of the show's first season and has only made sporadic appearances since then, Mick Rory has been a consistent member of the Legends for the show's six seasons. Dominic Purcell recently announced that he will be leaving Legends of Tomorrow at the end of its seventh season, but before then viewers have the chance to get to know his character's comic book counterpart a little bit better.

10 Heat Wave Was Originally Captain Cold's Rival

Captain Cold's first appearance in the comics predates Heat Wave's by six years, so Leonard Snart was already a formidable foe of the Flash by the time Mick Rory was introduced. Though the Arrowverse versions of these characters have been friends for as long as anyone can remember, what most people do not know is that Captain Cold and Heat Wave were originally rivals in the comics.

Heat Wave meets Captain Cold when they both attempt to kidnap the same woman due to their affections for her. Initially, Heat Wave helps Captain Cold out of a scrape with the Flash, but the two quickly start fighting when they realize they are after the same woman. This gives the Flash the opportunity he needs to capture them both.

9 Mick Rory Is Terrified Of The Cold

Another reason Heat Wave was not initially a fan or ally of Captain Cold: Mick Rory is terrified of the cold. As a child, he was locked in a freezer by some of his classmates as a prank during a field trip to a meatpacking plant. No one heard his cries for help, so he had to figure a way out of an industrial freezer by himself. Ever since, he has had a terrible fear of the cold, known as cryophobia, and a desperate need to keep warm, hence part of his desire to light things on fire.

8 He Once Worked As A Firefighter

Mick Rory wasn't always a criminal. There were multiple times he tried to abide by the law and use his tendencies for good. During one of the times Heat Wave attempted to live on the straight and narrow, he worked as a firefighter and a firefighting consultant. It was also during this time that he was friends with Barry Allen, the Flash, until he was eventually tempted by one of the other Rogues to return to his criminal pursuits.

7 Rory Built His Own Heat Gun

The comic book version of Mick Rory originally invented his own heat gun when he decided to take on the mantle of "Heat Wave" and become a supervillain. He gave his handheld flamethrower the nickname "Hot Rod." His gun can get so hot that it has actually been able to melt the Flash's boots, which regularly allow the Flash to run faster than the speed of sound without friction.

In the 1960s version of his villainous origin, Rory also made his own flame-retardant suite out of asbestos. Of course, now that the dangers of asbestos are known, Rory's rewritten origin features him designing a "costume insulated with thermal-dampening and heat-resistant material."

6 Mick Rory Joined The Circus

After his parents died in a fire he caused, Mick lives with his uncle for a while. Deciding that this was not a good fit and he could not stay at his uncle's, Mick runs away and joins the circus. He travels with the circus for a while as a fire eater. His job is temporary, however, as he eventually proves unable to control his fire obsession and one day sets fire to the circus. In the Arrowverse, the Legends visit P.T. Barnum's circus in season three, but sadly they were too busy trying to catch a loose tiger for Mick to display any of his fire-eating abilities.

5 Heat Wave Had Metahuman Abilities

DC Comics' New 52 reboot in 2011 saw many classic characters get makeovers following the events of Flashpoint. Mick Rory was one of these. In the New 52 continuity, Heat Wave has metahuman abilities that allow him to generate and control fire that emanates from his chest. Rory got his abilities from an experiment Captain Cold performed on the Rogues with a genome recorder. The genome recorder combined Rory's DNA with his heat gun, but a resulting accident also caused most of Rory's body to be covered in severe burns.

4 He Was A Member Of The Secret Society of Super Villains

As Leonard Snart joined the Legion of Doom in season two of Legends of Tomorrow to further his criminal enterprises, the comic book Mick Rory also had higher criminal aspirations than just being a part of the Rogues that he was able to eventually fulfill. In the events of the early 2000s DC storyline Infinite Crisis, Heat Wave joined a version of the Secret Society of Super Villains. Over the course of the years, notable members of this society have included criminals such as Lex Luthor, Talia al Ghul, Deathstroke, Black Adam, Gorilla Grodd, and Vandal Savage.

3 Captain Cold Worries Heat Wave Will Be Beyond Help

Captain Cold and Heat Wave are friends and partners, usually, but Captain Cold is also aware of the fact that Heat Wave is an arsonist and a pyromaniac. Pyromaniacs often intentionally set fires as a compulsive behavior.

Rory and Snart help to balance each other out with their respective obsessions of heat and cold, but Snart believes that eventually his influence will not be enough to keep Rory's pyromania at bay and Mick will become out of control.

2 Flashpoint Mick Rory Founded The Legion Of Doom

The Flash adapted the Flashpoint storyline in the first part of season three, but it was not nearly as widespread or damaging as the original Flashpoint. In the comics, every hero and villain in the DC universe was affected in one way or another by the broken timeline.

The Flashpoint version of Mick Rory was the founder and leader of the Legion of Doom. His Legion of Doom was composed of people he had met while in prison, such as the Thinker, Sportsmaster, and Plastic Man, and his main objective was to get revenge on Cyborg for nerve injuries he sustained during one of their previous encounters.

1 He Regretted Not Burning Down His Neighborhood

Legends of Tomorrow has done a good job showing the redemption arc of Heat Wave since his days as a bank robber on The Flash. In both the show and the comics, Heat Wave's origin story involves him burning down his childhood home with his family still inside. The Arrowverse's Heat Wave allows this to haunt him for much of his life; he carries his family's deaths with him until he finally has the chance to go back in time and talk to a younger version of himself. In the comics, Heat Wave tells the Flash plainly that his regret is not that he killed his family, but that he did not burn the whole neighborhood down along with them.
