Heatwave and the other members of the Rogues (Trickster, Mirror Master and Weather Wizard) were being tracked down by villains after being trapped in Gotham City. When confronted by a massive horde of Gotham thugs and criminals Heatwave made a selfless sacrifice to hold off their attackers to give the other Rogues enough time to escape.
It is unknown is Heatwave was killed during this battle or if he's currently in hiding.
Mick Rory was obsessed with fire from his childhood. He would stare at flames, and try to hold them He even set his house on fire and couldn’t take his eyes of the flames long enough to run to a neighbor for help. Before that, he had wanted to be a fireman.
At school, Heat Wave always wore winter clothes inside. The kids made fun on this. This led to a friend locking him in a walk-in freezer as a joke during a school field trip. Mick escaped, and was compelled to lock his friend in his house, and set it on fire. Mick often cited this freezer incident (leaving his friend’s part out of it) as a trauma that left him with an intense fear of cold.
He ran away from home, eventually joining a circus as a fire-eater. He was happy and thought he had his obsession under control, but it broke loose again, and he burned down the circus.
Rory was inspired by the Rogues to channel his obsession into a new identity. He invented a handgun-sized flamethrower and wore an asbestos suit and committed crimes under the identity of Heat Wave. When they met at a bank robbery, Captain Cold invited Heat Wave to join the Rogues.
Heat Wave was first introduced in The Flash #140 which was written by John Broome. He was first made to be a rival for Captain Cold, however in recent comics by Geoff Johns, Rory looks to Captain Cold to help him keep his obsession at bay, though Cold thinks he'll eventually become beyond help.
Mick Rory first made his comic book appearance as a friendly rival to Captain Cold in The Flash #140. The two worked together to try and defeat The Flash, but at the same time, Cold and HeatWave bickered and fought a lot. One significant moment for Mick in the Silver Age was that he was recruited by Captain Cold at a bank robbery to join the team, The Rogues.
Not a lot happened for Mick Rory during this time period. One thing he did do was make Barry Allen into a "flaming menace", he essentially made it that every time Flash would run, fire would spew behind him.
Heat Wave eventually decided to be good after the events of Underworld Unleashed. He began working as a firefighting consultant, using his knowledge of heat and flames from his former criminal career.Still struggling with his pyromania, he began working for the F.B.I. alongside other reformed rogues
The F.B.I. project failed. On the group’s first mission, the Top returned to undo the programming that had caused most of them to reform. Heat Wave rejoined the Rogues. He then joins the Secret Society, led by Alexander Luthor.

Flashpoint: Legion of Doom
In the Flashpoint universe, Heat Wave desperately wants to be part of Firestorm. He kills Jason Rusch, trying to force Ronnie Raymond to give him half the matrix; however, he is interrupted by Cyborg and eventually defeated. The result of this encounter is a series of massive burns across Heat Wave's body and Heatwave being sent to death row for his murder.
Heat Wave has his equipment taken from him as is protocol for all inmates. Heatwave uses a series of connections to get Cluemaster to smuggle in an evil and sadistic Plastic Man. Together the two of them begin their escape, during the process Heatwave is attacked by Animal Man (another inmate) whom he defeats and then curb-stomps.
Due to the fact that Plastic Man was never registered as an inmate none of the security systems have a defense mechanism against him. He is instructed by Heatwave to attack Amazo (the head of security) in the eyes, in doing so he finds that Ray Palmer (the Atom) had been running the Amazo robot from the inside.
Heat Wave kills Palmer by squishing his head between his fingers. He then obtains his stolen gear and begins flying the prison towards Detroit much to the dismay of the other inmates. Plastic Man attempts to intervene; however, Heatwave turns on his partner and melts him with his intense flames.
Heat Wave's plan to escape fails; however, and he's sent back to death row where he is met once again (to his horror) by Plastic Man who had somehow survived the intense blast of Heat Wave's flames.
Origins - Slow Burn
In the New 52 Heat Wave used the Genome Recoder to merge his DNA with his weaponry; in his case, a flamethrower. Unfortunately there was a massive power surge within the machine which destroyed the building he and the rest of the Rogue's were in. Heat Wave woke to find 90% of his body covered in third degree burns.
Thankfully the Genome Recoder served it's purpose and Heat Wave was able to manipulate fire and project it from his own body; thus granting him pyrokinesis.
It was shown that due to the scarring that the power surge caused, Heat Wave became a rival to Captain Cold, even going to far to completely ignore the Flash when he tried to intervene on their fight. Eventually the two were able to put aside their past differences and team up as Rogues once more.
Heat Wave was a member of the Rogues when Gorilla Grodd and his army attacked Central City. Along with the other Rogues he used his powers to protect himself and the citizens of Central City; however, it was discovered that the Rogues were just pretended to be "good" and were actually forcing the citizens they saved to pay them by giving them all of their valuables.
Forever Evil - Rogues Rebellion
The Rogues had a bounty put on their head by the Crime Syndicate. In order to escape capture the Rogues (Trickster, Mirror Master, Weather Wizard, Captain Cold and Heat Wave) worked together to fight off waves off villains whom came to claim the bounty; however, during their encounter with Power Ring and Deathstorm they lost contact with Captain Cold.
When in Gotham Heat Wave bonded with Mirror Master as the two of them fought against a horde of Man-Bats.
While trying to escape Gotham the Rogues were stopped by a massive amount of thugs and criminals. In order to give the others time to escape Heat Wave jumped off of their escape vehicle into their attacks and use his powers to create a massive explosion in the shape of a phoenix.
It is unknown if Heat Wave survived this encounter or not as he has yet to appear in future issues.
