Species: Enhanced Humannote
Known Aliases: Firestorm
The entity formed as the result of the F.I.R.E.S.T.O.R.M. matrix combining with two people, merging them into a single nuclear powered superhero.
- Achilles' Heel:
- Firestorm is dependent on the Quantum Splicer to fuse. If the device isn't functioning, then they can't combine into Firestorm, and in case they manage to, the chance of defusion is nearly impossible.
- Large masses of water can separate their fusion, as shown when Weather Wizard smashed them with a wave shaped like a fist.
- Adaptational Attractiveness: In the comics and other adaptations, Firestorm has straight out Flaming Hair. Here, it only happens when he activates his powers, and even then, the Tall, Dark, and Handsome appearance of his host body remains visible.
- Adaptation Expansion: Not him/them, but rather his/their Chest Insignia. In the comics, it's simply just part of the costume. Here, it functions as a stabilizer for him/them during the Fusion Dance.
- Double Consciousness: A literal example of this, as while they are combined as Firestorm, they are two minds sharing the same body. It was initially taken to extremes when Stein and Ronnie were initially fighting each other for control, unable to separate their memories and desires.
- Energy Absorption: All Firestorms have the ability to absorb energy from nuclear blasts. Firestorm II was able to absorb the blast from Vandal Savage's nuclear warhead, containing the fallout to a safe levels.
- Flaming Hair: All versions' heads set ablaze when activating their powers. Though unlike the comics version, the hair itself isn't fire where instead a flame emanates from their hair.
- Flying Firepower: All versions of them can fly by projecting nuclear blasts on the ground.
- Fusion Dance: All versions of Firestorm are the result of two individuals fusing together into one body, with the Firestorm-I happening unintentionally as the result of the Particle Accelerator explosion.
- Fun with Acronyms: Fusion Ignition Research Experiment and Science of Transmutation Originating RNA and Molecular structures. You really have to wonder how long it took Stein (and, by proxy, the show's writers) to come up with something that spelled out "Firestorm".
- Hand Blast: Firestorm's primary means of attack and how they are able to fly is to aim their hands downward with enough force to defy gravity, enabling stable propulsion and gliding.
- How Do I Shot Web?: Every Firestorm has had difficulty controlling the powers to begin with. Jax is the only one who was able to have a teacher as Martin already had experience as Firestorm for a year.
- Iconic Sequel Character: The original does not appear until the Arrowverse's third year, while the second doesn't show up until the fourth.
- Playing with Fire: All versions are able to project fiery Hand Blasts as offensive attacks or for flight.
- Power Perversion Potential: When separated from their initial fusion, they can feel what the other is feeling. Now imagine if one or both of them are having an intimate time with their respective lady loves...
- Prophet Eyes: While merged, all Firestorms will possess white irisless eyes.
- Psychic Link: Due to being fused together in the Firestorm matrix, both members of Firestorm feel when the other is in great distress or pain. There are also other side effects such as one member of Firestorm's fondness for a particular food seeping into the other member.
- Sharing a Body: By means of a Fusion Dance, as Firestorm he has the minds of two individuals inhabiting a single body.
- Wreathed in Flames: At first their entire body would combust, while a more controlled appearance only has their heads on fire.
Known Aliases: Firestorm, "Burning Man"
Played By: Robbie Amell (body) and Victor Garber (mind)
Appearances: Flash vs. Arrownote | The Flash
A "man on fire" who is rumored to be hiding under a bridge somewhere in the city. The military has some interest in him, he is startling similar to Ronnie Raymond, Caitlin's supposedly dead fiancé and he is in some way connected to Professor Martin Stein's research.
It is then revealed that he is in fact Ronnie, but also Professor Stein, as the two were fused thanks to the Particle Accelerator explosion. With Team Flash's help, Ronnie and Stein have both been separated and learned to re-fuse at will.
After the battle against the Reverse-Flash, a wormhole opens in the sky of Central City. While Barry is attempting to close it, a strong energy similar to the one they produce when Ronnie and Stein fuse and defuse is needed to complete the process. Because of this, they decided to perform a Heroic Sacrifice. Barry was ultimately able to save Stein but not Ronnie, who apparently dies.
- Adaptational Wimp: In a way, since he wasn't able to even learn the molecular transmutation skill that his comic counterpart has.
- Alphabetical Theme Naming: Ronnie and Prof. Stein's respective Love Interests are Caitlin Snow and Clarissa Stein.
- Big Damn Heroes:
- He shows up just in time to save the Flash from the Reverse-Flash in "The Man in the Yellow Suit".
- He performs another one by tag teaming with The Arrow to take down the Reverse-Flash in "Rogue Air".
- Performs their biggest one by stopping the Singularity, though a sacrifice had to be made with Ronnie having been presumed deceased as only Dr. Stein came back out.
- Civvie Spandex: This version of Firestorm is not wearing a proper costume, and instead wears whatever clothes his host body is wearing.
- Comic-Book Movies Don't Use Codenames: Zigzagged. Though he at first identifies himself as "Firestorm", he was eventually revealed to have been referring to the F.I.R.E.S.T.O.R.M. project by Professor Stein. Once General Eiling starts pursuing him he's consistently referred to as Firestorm by Eiling and his people. Though they are actually talking about the matrix that caused Firestorm's powers, the man and the matrix are one and the same so in practice he does have a codename.
- Deus Exit Machina: Flash finally gets a metahuman on his side (that lasts longer than an episode, at least), but unfortunately, Firestorm has to go into hiding in another city.
- Fire-Forged Friends: Both literally and figuratively. The Flash himself counts as a figurative example.
- Heroic Sacrifice: Performs one to close the wormhole atop Central City. Prof. Stein made it, but Ronnie apparently didn't.
- Heroic Suicide: Attempted when they hear Team Flash talking about him going nuclear and potentially destroying Central City. To be more specific, Stein thought of it while Ronnie protested given they're sharingbhis body, and the latter resented the former for a while because of this.
- Homeless Hero: Subverted. He was homeless for nearly two years before he official became a superhero. This is due to both of his components still having no idea at that time on how to control their newfound powers and abilities.
- Living MacGuffin: Team Flash want to help Ronnie, but Eiling's got his eyes on the Firestorm Matrix.
- Older Than They Look: While they're still Sharing a Body, Martin Stein tried introducing himself to an old colleague, who mistook "Ronnie" for a student in the college where he worked when Stein said "they went to school together".
- Together in Death: When they performed a Heroic Sacrifice to close the wormhole that is about to engulf Central City, though only Ronnie (apparently) dies. Invoked during Stein's death, as Caitlin told him during his funeral to say hi to Ronnie for her.
- Walking Spoiler: Thanks to his identity not being revealed until the ninth episode (and The Stinger of the eighth episode), when he's introduced.
Known Aliases: Firestorm II, Ares the God of War
Played By: Franz Drameh (body, briefly mind) and Victor Garber (mind, briefly body)
Appearances: The Flash | Legends of Tomorrow | Invasion!note | Vixen | Crisis on Earth-X note
After Ronnie sacrificed himself to save Central City, Professor Stein began to die without having another partner to fuse with. Luckily a young mechanic proved to be the ideal match.
- Attack Its Weak Point: The quantum splicer is what enables Stein's and Jax's Fusion Dance and when a brainwashed Rip Hunter disables it with an EMP, they de-fuse and unable to merge until it's fully functional again.
- The Big Guy: He's one of the Legend's go-to guys when it comes to fighting.
- Brought Down to Normal: A fatally wounded Stein gives Jax a serum to remove their Psychic Link and Fusion Dance capabilities in order to prevent the latter from also dying.
- Civvie Spandex: He is wearing Jax's casual clothes in his first outing as he is in a hurry due to Tokamak wrecking havoc at the time. Starting with his second appearance, however, he's been wearing the red and yellow comics costume every time his two components fuse together.
- Composite Character: Puns aside, the second version of Firestorm in the comics is Jason Rusch (who already appeared in the first season). Jefferson Jackson is merely Ronnie's Black Best Friend there. This version of Firestorm is clearly inspired by Rusch's tenure.
- Fire-Forged Friends: Literally and figuratively, though their initial relationship wasn't as nearly rough as it was with Ronnie.
- Glass Cannon: Easily the most powerful of the Legends in terms of raw power, but goes down in one hit from Barry's lightning attack in "Invasion!" and a single arrow from Merlyn in "Aruba," the latter even causing him to de-fuse.
- Iconic Outfit: By the time of his second appearance on Legends, Firestorm wears the yellow and red costume from the comics.
- Legacy Character: Jax succeeded Ronnie as the host body for Firestorm, hence Firestorm-II was born.
- Matter Replicator: In the Season One finale of Legends , he discovered a new power. Just as in the comics, Firestorm can now transmute elements and he turned a Thanagarian meteor into a large puddle of water.
- Salt and Pepper: He's a combination of a Caucasian man (Stein) and an African-American man (Jax).
- Story-Breaker Power: Being the most powerful Legend who could single-handedly handle most of the threats the team encounters, Jax and Stein often find themselves physically separated from each other when the plot demands it.
- Superior Successor: He is able to learn his molecular transmutation skill and demonstrate his Energy Absorption abilities, both of which being something the Ronnie/Stein version wasn't able to.
- Walking Spoiler: It's hard to talk about him without discussing what happened to the original Firestorm.
Professor Martin Stein / Firestorm
Nicknames: "Grey" (by Jefferson), "Marty" (in his youth)
Affiliations: Team Flash, The Legends
Played By: Victor Garber, Graeme McComb (1975)
Appearances: The Flash | Legends of Tomorrow | Invasion!note | Vixen | Crisis on Earth-Xnote
The creator of Project F.I.R.E.S.T.O.R.M., who mysteriously vanished the night the particle accelerator exploded. Prof. Stein had actually been affected by the accelerator's dark matter wave merging with the thought-to-be-deceased Ronnie Raymond and his creation, the Firestorm Matrix, becoming the meta-human known as "the Burning Man," with Prof. Stein's mind taking control of Ronnie Raymond's body.
Their powers greatly endangering both their lives due to the unstable Firestorm Matrix, Stein and Ronnie eventually came to accept each other as partners forming the conjoined hero known as Firestorm. After Ronnie's sacrifice to save Central City from the Singularity, Stein was in danger from the Matrix once more, but was saved by a potential replacement for Ronnie in Jefferson "Jax" Jackson.
Along with "Jax", he join Rip Hunter's team. In Crisis on Earth-X, after being fatally shot, he took a serum used to disband Firestorm in order to prevent Jax from dying alongside him.
- Absent-Minded Professor: Shows shades of this, being a bit forgetful at times such as failing to remember teaching Ray Palmer. He literally gets called this by Caitlin after his interactions with his past self lead to him having a daughter which he had no recollection of.
- Action Dad: After interacting with his past self and telling him to cherish Clarissa, the timeline is altered and he has a daughter, Lily.
- Adaptational Intelligence: Martin Stein from the comics is smart without question, but he's mostly only depicted as a nuclear scientist. This version also displays knowledge on Time Travel and Alternate Reality, and it is implied that he knows a lot more.
- Adorkable: Just watch him excitedly ramble on about time travel and alternate universe. He even nicknames a super villain, much to Cisco's approval. When Rip and some of his teammates were captured by Time Pirates, he gleefully takes on the role of "Space Ranger", a comic that he loved as a child.
- Ambiguously Jewish: Though the Season One finale of The Flash (2014) throws off the ambiguous part. He's not just Jewish, he's an ordained rabbi.
- And Starring: Is given a "Special Guest Star" on The Flash.
- Badass Teacher: He is a professor, and Ray was even a former student of his.
- Been There, Shaped History: In 1870 he saves the life of a boy dying of tuberculosis, learning afterwards that his name is Herbert George Wells.
- Birds of a Feather: He and Ray are the team's resident scientists, and get along particularly well. Sara and Jax even refer to the two of them as the "nerd twins".
- Brought Down to Normal:
- When Firestorm helped Barry close a singularity threatening to destroy Central City, Ronnie apparently died, leaving Stein without full access to his Firestorm powers. He regained them when he fused with Jax instead.
- Happened permanently when a severely injured Stein used a serum to sever his Psychic Link with Jax so the latter won't die with him.
- Catchphrase: "Astonishing."
- Celebrity Paradox: Titanic (1997) was mentioned by Jax in The Flash (2014), and Ray mentioned the real one in Episode 3 as an Actor Allusion since his actor, Victor Garber, was part of that film's main cast.
- Chekhov M.I.A.: He's first introduced having already gone missing, after heading off to confront the person who shut down his work. Whoever it was must have worked at S.T.A.R. Labs, as he was there the night of the explosion and was fused with Ronnie.
- Cool Old Guy: He gives Barry advice about his love life. Later, he gives Eddie a solid pep-talk when Eddie's feeling the effects of Thawne's Breaking Speech, denigrating him as the "disappointment" of the Thawne family. He also comes to be a Team Dad of sorts to the Legends and everyone looking up to him like a father figure.
- Deadpan Snarker: Quite a bit, mostly about the crew discussing things quite loudly.
- Death by Irony: Before he dies, he drinks a serum to sever his and Jax's ties to the Firestorm matrix in order to save the latter's life. His Earth-2 counterpart died because he was forcefully trapped inside Ronnie's body when the latter was killed off.
- Defrosting Ice King: He is at first very cold to Team Flash and the idea of camaraderie with them, but after being saved by them, he warms up to them, even taking the role of Team Dad for a few episodes.
- Face Death with Dignity: Twice.
- He spends his final moments comforting Jax and thanking him for the adventure of a lifetime.
- His past self learns the exact date of his death but decides not to try and change anything, since he'll be an old man who's lived a full life with a loving family and friends who care about him.
- Fan Boy: Of Space Rangers.
- Flat-Earth Atheist: Both he and Palmer express disbelief that magic was involved in the origin of Savage and the Hawks. He seems to find it more believable when Ray comes up with the idea that the meteorites carried some sort of mutagen that altered the three. He at least has a greater justification for thinking this, as he hasn't had the opportunity to be as exposed to magic as Ray has.
- Forgotten First Meeting: He couldn't remember that Ray was a former student of his. Justified in that Stein is a seventy-year-old man and can't be expected to remember one student from one semester after close to fifty years of teaching.
- Happily Married: Despite a bad habit of putting his work first, he enforces time and again that he loves his wife Clarissa. In the new timeline, a daughter was born from their relationship.
- Heroic Sacrifice:
- Attempted in The Flash Season Two. He shuts down the wormhole by going into the middle of it as Firestorm and separating. He makes it out alive, but Ronnie, to everyone's dismay, does not.
- In Crisis on Earth-X he goes to open the breach to Earth-1 despite the great risk of getting shot by the Nazis, and he does. It costs him his life
- Heroic Suicide: He tries to kill himself in Ronnie's body so it will not go nuclear and kill everyone. Thankfully averted.
- Heterosexual Life-Partners: While their relationship isn't without some strife, it's clear that Stein and Jax are each one of the most important people in each others' lives.
- Hidden Badass: Despite usually being the Non-Action Guy, Stein's tougher than he looks, even without the Firestorm matrix.
- After getting captured by General Eiling, he was tortured in order to get the secrets of Firestorm, but managed to resist (something even Eiling was surprised by) without saying a word.
- He endured a similar treatment when he was captured by Valentina Vostok and Vandal Savage in 1986, only giving in when they threatened Ray Palmer and Mick Rory rather than himself.
- Was able to beat a time-pirate hand-to-hand all by himself, even walking away with his weapon and hat afterwards.
- Takes it one step further in Season Three by managing to overpower Damien Darhk, the man that killed Sara's sister Laurel in the present.
- Hidden Depths: Stein's singing voice is beautiful enough to move a Nazi general to tears.
- Hippie Teacher: Though we've yet to see him teach a class, he is a professor and he did protest the Vietnam War in college.
- Hypocrite: Defied trope. He is one of the few people to not criticize Barry over Flashpoint, and admits that he would do the same thing for his family, and in fact does the same thing when he asks Jax to not bring up that his daughter was born from his accidental meddling with the timeline.
- Iconic Sequel Character: While he's introduced during The Flash (2014) Season One, this means he does not appear in the Arrowverse until its third year.
- I Hate Past Me: He is annoyed by his twenty-five-year-old self, partly for being a pot-smoking hippie, but also because of how similar he is, and he laments that after all this time he is still much the same.
- I'm Mr. [Future Pop Culture Reference]: He introduces himself to his younger self as "Professor Elon Musk".
- Intergenerational Friendship:
- Hits it off pretty fast with most of Team Flash, especially Barry.
- He and Ray Palmer get along quite well too, due to both being scientists. He's old enough to have taught Ray a long time ago.
- Insufferable Genius: He can verge into this, especially as a young man. After having to deal with his past self, he acknowledges this as his biggest weakness.
- Jumped at the Call: He was very excited at the prospect of time travel.
- Knight In Sour Armor: He's less than impressed with the team, giving a snarky description for each of them that makes for great trailer fodder.
- Killed Off for Real: Dies in the final part of Crisis on Earth-X.
- The Lancer: He and Jax share the role as Sara's deputies in Season Two.
- Last-Name Basis: He has a notable habit of addressing his teammates this way, e.g. "Miss Lance", "Mr. Rory", "Dr. Palmer", etc. When he calls Sara by her first name, she realizes something is up.
- Legally Dead: He was missing for over a year after the Particle Accelerator explosion.
- Like a Son to Me: Comes to see Jax as this, realizing that before he had unexpectedly found himself with a daughter, he had already unexpectedly found himself with a son. This actually extends to the whole Stein household who see Jax as a part of their family, with Clarissa seeing him as a son and Lily considering him a brother.
- Made of Iron: Despite his age and stuffy academic demeanor, he was able to resist being physically tortured for the secrets to the Firestorm matrix twice.
- Mad Scientist: He was messing around with molecular transmutation, on a project whose name Ronnie gives Caitlin as the only clue for what made him a meta-human. Subverts this in that he realizes the potential for his research to be misused.
- Married to the Job: Before the reactor explosion, he was more interested in his research than his wife, to his regret. He can't resist advising his past self to be a better husband... which leads to him retroactively fathering Lily.
- Minored in Ass-Kicking: In "Marooned", he is able to save the team on his own, taking out a time pirate. And on his own, no Firestorm powers at all.
- Mr. Vice Guy: He has clear problems with his pride. He is aware of this and hates himself for it.
- My God, What Have I Done?:
- He acknowledges that he was wrong to drug Jax and force him to join Rip's team when Jax pulls a What the Hell, Hero?.
- He has another one when his interactions with his past self cause the timeline to be changed such that he never married Clarissa. Rip fixes it for him, knowing the pain of losing a wife.
- My Greatest Failure: He considers Ronnie's death to be this, and is why he is so hard on Jax, because he doesn't want to lose him too.
- My Greatest Second Chance: During the final part of the crossover, dying from his wounds, Stein forces Jax to sever their connection in order to save the latter's life. While he wasn't able to save Ronnie, he was able to save Jax.
- Nerd Glasses: Because Smart People Wear Glasses.
- Never Trust a Trailer: In trailers, he is shown to be skeptical about the idea that Ray is a Size Shifter. In the show proper, not only is he not skeptical in the slightest but at one point in the second half of the pilot he actually smuggles Ray into a meeting in his pocket.
- Nice Guy: Despite his issues with pride, he's really polite to Team Flash and later Team Legends.
- Non-Action Guy: Without Jax. Well, with Jax, he's still this since he's only providing the strategy and has no control over their body, but he's there in spirit. Subverted in Legends 1x07; when Rip and the others are captured by the space pirates, it's up to him to rescue them. And boy, does he ever.That'll teach them to mess with a nuclear physicist.
- Not That Kind of Doctor: As he reminds Rory, his doctorate is in nuclear physics, not medicine.
- Not So Above It All: Usually carries himself with a more serious and cerebral demeanor compared to Team Flash or the Legends, but nicknames Atom Smasher for Earth-2 Al Rothstein with childlike glee.
- When Jax asks if he's ready for their push to take the Nazi compound housing the gateway back to Earth-1 in Crisis on Earth-X?
- Not Using the "Z" Word: He doesn't like to use the word "zombie" even when the team has to fight them, due to a (previously) irrational fear of them, but he quickly gets over the aversion when Mick gets infected.
- Only Sane Man: He's typically the least erratic of all the Legends and tries to be the voice of a reason.
- Parental Substitute: Jax sees him as a substitute father and the way Stein acts around Jax is suitably paternal in return. This makes his death extra difficult for Jax.
- Pride: Arrogance is his flaw, causing his mistakes; he knows it and is ashamed of it.
- The Professor: And literally addressed as such, too.
- Psychic Link: Once fused with someone as Firestorm, he shares this with them regardless.
- Quickly Demoted Leader: He assumes the mantle of the Legends' leader after Rip's disappearance. However, he soon feels that he's unsuited for the job, so he gracefully gives the mantle to Sara.
- Real Life Writes the Plot: Killed off in Crisis on Earth-X so his actor could return to Broadway.
- Required Secondary Powers: Even when he's not in Firestorm mode, he is almost immune to radiation. He can even take an unshielded thermonuclear core with only a slight dizziness spell.
- Retirony: Just when he and Jax found a way to break up Firestorm so Stein could retire as a legend and be with his family, he gets killed during the Crisis on Earth-X four-parter.
- Salt and Pepper: With Jax. He's the Salt of the pair.
- Sesquipedalian Loquaciousness: Stein's manner of speaking is very florid and sophisticated. It irritates the more straightforward Jax to no end.
- Shoot the Shaggy Dog: Just when he was about to retire and spend some well-deserved time with his family, he dies.
- The Smart Guy: He is a world-renowned scientist and serves as The Professor to the Legends, with him and Ray sharing the role of scientists.
- Static Character: Discussed Trope. After seeing his past self he's afraid for 60 years of life he hasn't matured at all. Jax assures him this isn't true, and he does in fact go through some Character Development.
- The Stoner: Back in college, he got up to it as much as anyone else in the '70s.
- Survivor Guilt: He tells Ray the reason he is so hard on Jax is because he still feels guilty for Ronnie supposedly Dying Alone when they made the Heroic Sacrifice to close the wormhole
- Team Dad: After Eobard Thawne is outed, Team Flash is left without a lead experienced scientist until he returns for the Season One finale. He continues serving in this role in the early episode of Season Two before he leaves to train Jax as the new Firestorm.
- They Call Me Mister Tibbs: Played for Laughs. Stein is briefly made Captain due to Rex Tyler presuming he was due to his senior age. When Jax calls him Grey, Stein says "That's Captain Grey to you."
- Together in Death: With his first partner, Ronnie Raymond. Caitlin even tells him at his grave to greet Ronnie for her.
- Took a Level in Badass: From mostly a Non-Action Guy while not merged, he gradually becomes an at least fairly competent Action Survivor in time.
- Trademark Favorite Food:
- He has learned to love pizza due to being fused with Ronnie for 14 months. He hated it before.
- Martin has a fondness for grapefruit and as a result Jax craved it too. When Ray helps to temporarily cut their Psychic Link, Jax was delighted for the first time in years he didn't crave it in the morning.
- Transplant: He was a major key character on the first season of The Flash (2014) and a Recurring Character in the second before becoming a member of Rip Hunter's team.
- Trapped in the Past: He and Jax get trapped in the Medieval Era after Rip time scatters the team during the Season Two premiere.
- Verbal Tic: Has a very formal way of addressing people, always by their title and surname (Ms. Lance, Captain Hunter, Dr. Palmer) rather than by their first name. He also eschews nicknames, addressing Ronnie and Jax as Ronald and Jefferson, much to their consternation at first.
- What the Hell, Hero?: Stein drugged Jax and forced him on the trip, which Jax is understandably not terribly pleased about. However, it's later implied that Jax's own future self was the one who gave him the idea in the first place.
- Wine Is Classy: In "The Nuclear Man", he mentions a fondness for Chateau Haut-Brion, Pessac-Leognan 1982. And in "Legion of Doom", when Jax asks if he's drinking coffee mixed with whiskey, Stein retorts:
- Your Approval Fills Me with Shame: Played with. His quick thinking and actions in both parts of the pilot earn most of the team's approval, but especially Mick Rory's — he doesn't quite know how to handle that yet.Mick: Whatever you roofied him with, I'd like some.
Stein: I did not roofie him!
Mick: Oh, I ain't judging.
Ronald "Ronnie" Raymond / Firestorm I-B
Species: Enhanced human
Known Aliases: Firestorm, Burning Man
Played By: Robbie Amell
Appearances: The Flash
Caitlin's deceased fiancé, and the head engineer for the particle accelerator. He died the night it malfunctioned, giving his life in order to prevent the entire building from being destroyed. It is revealed he is actually alive, but the dark matter wave had merged him with Prof. Martin Stein and had become the host body for the Firestorm Matrix.
Due to the two being's confusion and inability to operate cohesively, the meta-human "the Burning Man" became erratic and dangerous, until Team Flash provided them with a solution to stop fighting their merging and a way to control the Matrix, the two became the hero known as Firestorm, and Ronnie happily reunited with Caitlin, and the two eventually married. Shortly after this, however, Ronnie gives his life to save Central City by closing the Singularity, but Stein survives.
- Adaptational Intelligence: Ronnie's intelligence in the comics is nothing to write home about. He's even Book Dumb by his own admission. Here he's the head engineer of the particle accelerator and the one who adjusts it to minimize the damage it would have done.
- Age Lift: Ronnie is traditionally a teenager when he becomes the superhero Firestorm; here, he's roughly in his mid-to-late twenties.
- Alliterative Name: Ronnie Raymond.
- And I Must Scream: How he describes his initial situation with Stein. Cisco asks him what it's like to have those powers, except Ronnie complains that he'd be enjoying every minute of it, if he were actually in control. Thankfully, their situation is remedied by the end of the two-parter where they return, and while Ronnie is in primary control of the body, Stein communicates to him as a mental voice.
- And Starring: Was credited as a "Special Guest Star" only in the penultimate episode of Season 1. In the Season Finale, he reverts back to the regular guest star lineup. Season 2 permanently restores him to the "Special Guest Star" citation.
- Badass Normal: When cornered by the military, and the Flash got incapacitated by a Trick Bomb, Ronnie socks Eiling hard enough to topple him and help the Flash into the S.T.A.R van.
- Beware the Nice Ones: Ronnie is an overall decent fellow, but Cisco mentions that Ronnie is dreadful when furious and stressed-out.
- Came Back Wrong: Seems so at first, though it's eventually revealed it's actually Martin Stein in Ronnie's body.
- Cynicism Catalyst: For Caitlin.
- Dead Alternate Counterpart: For Deathstorm. Deathstorm doesn't know about him per se (due to also dying), but Ronnie's death was used by Cisco to get on the good graces of Killer Frost, Caitlin's Earth-2 Alternate Self who is also Deathstorm's wife.
- Do Not Call Me "Paul": Does not like being called Ronald.
- The Engineer: The head engineer of S.T.A.R. Labs prior to the Particle Accelerator explosion.
- Fire/Ice Duo: Downplayed with Caitlin, as they never had their respective elemental powers together. When Ronnie became one half of Firestorm, Caitlin had yet to develop ice powers. By the time Caitlin became Killer Frost, Ronnie was long since dead. However they did match the trope personality wise with Ronnie once describing them as being "like fire and ice."
- Heroic Sacrifice: He went inside the accelerator in order to manually redirect the explosion, and made Cisco close the blast doors in two minutes in case he didn't get back in time. He didn't make it back in time. Happens again in the beginning of Season 2, where he shuts down the wormhole by going into the middle of it as Firestorm and the separating. Professor Stein makes it back, but he does not.
- Hot Scientist: He's smart enough at engineering to help design the accelerator. He's also extremely attractive. Not so much immediately after coming back, but He Cleans Up Nicely again by "The Nuclear Man".
- Iconic Sequel Character: Introduced to the Arrowverse during its third year.
- I Just Want to Be Normal: Immediately after being separated from Prof. Stein after their initial (and unwilling) Fusion Dance, he asked Caitlin to move away from Central City with him to have a normal life. Realizing that Eilling will continue to hunt him and Stein (who was eventually captured) down for the F.I.R.S.T.O.R.M matrix as well as being inspired by Barry, he finally accepted his (and Stein's) condition.
- In Spite of a Nail: Despite Barry creating three Cosmic Retcons after his death, he still ends up dead in two of it. It's unclear what happened to him during the Flashpoint timeline.
- Legally Dead: Twice. First when he's been missing for over a year. The second happened only a few months after coming back. Both times, his body was never found, and everyone considers him dead after the second.
- Looks Like Jesus: After he Came Back Wrong.
- The Lost Lenore:
- To Caitlin. Double subverted in that he was revealed to have survived the particle accelerator explosion, but later never made it out of the singularity.
- Martin Stein never gotten over his supposed death either, and he was very hard on Jax, Ronnie's successor, on fear of losing him like he lost Ronnie.
- Never Found the Body:
- A given, since he was vaporized by the particle accelerator explosion. Except he wasn't; The Stinger for "Flash vs. Arrow" reveals that he's still alive, and acquired the abilities of his comics counterpart.
- And again in "The Man Who Saved Central City", where he apparently was lost when he and Professor Stein de-fused in order to destroy the singularity.
- Opposites Attract: He was warm and jolly, she was cool and logical. They brought out each other's best, and he even referred to the two of them as "fire and ice".
- Posthumous Character: Killed in the accelerator explosion. Psych — he actually survived and has become a metahuman.
- Related in the Adaptation:
- Inverted with Felicity Smoak. In the source material, she's his stepmother. Here, they don't even know each other personally (yet).
- Played straight with Caitlin, whom he marries in the Season 1 Finale. In the comics, they're enemies (though not without Foe Romantic Subtext, especially on the latter's part).
- Secret Keeper: Upon being calmed down shortly before his and Prof. Stein's initial separation, he/they becomes aware of Barry's identity as The Flash.
- Tall, Dark, and Handsome: He's 5'11.
- Together in Death: Invoked by Caitlin after Stein's death by telling the latter to say hi to him on her behalf.
- Trademark Favorite Food: Pizza. Ronnie always liked it, and once he became psychically linked, Professor Stein grew to love it too when he originally despised it.
- Two First Names: Being a DC Comics based character, he has a last name that is traditionally used as a first name.
Jefferson "Jax" Jackson / Firestorm II-B
Known Aliases: Firestorm II, "Henry Scott"
Played By: Franz Drameh
Appearances: The Flash | Legends of Tomorrow | Invasion!note | Vixen | Crisis on Earth-Xnote
A car mechanic and former collegiate athlete whose career came to a scratching halt after the Particle Accelerator exploded. After Ronnie sacrificed himself to save Central City, Professor Stein began to die without having another partner to fuse with. Initially reluctant at first, Jax ultimately accepted to be his new "co-pilot". After Stein's death from the events of Crisis on Earth X and receiving closure by meeting with his past self in 1992, he left the Legends to make a new start. 5 years removed from the present, he is revealed to be married and with a baby girl named Martina.
- Abled in the Adaptation: Or disabled. The comicbook version of Jax is never mentioned to have an injury, whereas this version's backstory is built around his Career-Ending Injury.
- Academic Athlete: Former high school football player who had a 4.0 grade average at school and could've apply for an academic scholarship.
- Adaptational Badass: In the comics, he's merely Ronnie's football teammate and Black Best Friend. Here, he is his successor as Firestorm.
- Age Lift: Like Ronnie, he's traditionally a teenager. Here, he's in his early twenties while Ronnie is more or less almost a decade older than him.
- Alliterative Name: Jefferson "Jax" Jackson.
- Ascended Extra: In the comics, Jax is merely Ronnie's Black Best Friend. Here, he's Ronnie's successor.
- The Baby of the Bunch: He's the youngest member of the cast, both In-Universe and out. The other Legends treat him like a little brother or a son.
- Badass and Child Duo: Played with. He's both the badass and the child of the duo with Stein.
- Badass Normal: It's easy to forget the guy used to be a football player, which means that even when he doesn't have his Firestorm powers he has no problem tackling Mooks and beating the stuffing out of them.
- Beware the Nice Ones: He was ready to execute a brainwashed Rip after seeing him kill Sara. It took a revived Sara quite a bit of effort to talk him out of killing Rip.
- The Big Guy: Aside from Firestorm, Jax is also a former athlete and a Badass Normal more than capable of holding his own in a fight.
- Brought Down to Normal: After Stein's death, he no longer can transform into Firestorm. That doesn't mean however that he can't still kick some serious ass.
- But Now I Must Go: He decides to leave the Legends now that Stein is dead and he can't turn into Firestorm.
- Career-Ending Injury: He saved a student on crutches who couldn't get away during the night the Particle Accelerator exploded, at the cost of an injury that derailed his promising football career and cost him his chance to go to college. It would be an understatement to say he's more than a little bitter about it. It also almost cost him his life when he ran to save Stein from Volstok.
- Composite Character:
- He exists in the comics, but his role as the second Firestorm and Ronnie's successor originally belongs to Jason Rusch (who already appeared in Season One of The Flash).
- Furthermore, his personality and status as a jock are aspects taken from Ronnie Raymond, whose Arrowverse counterpart has a case of Adaptational Intelligence and was a renowned engineer before his death.
- Deadpan Snarker: Pretty often.Stein: It couldn't have been so easy for Raymond either, I mean...give up being the Atom?Kendra: I'm sorry, can we have a private moment?Jax: I think we all wish you would've had this moment in private.
- Disappeared Dad: He never knew his father, who was killed in action shortly after Jax was born. He finally meets him near the end of Legends of Tomorrow Season One.
- Early-Bird Cameo: Made a guest appearance in The Flash months before the ;;Legends'' series premiere.
- The Engineer: Of the Waverider; he is trained by Rip to be its main mechanic.
- Evil Knockoff: When Jax and Sara go into Rip's mind, they encounter evil mental projections of themselves. Evil Firestorm has red Prophet Eyes, red flames, and an Evil Costume Switch where the red accents are now black.
- Genius Bruiser: Back in The Flash, it was mentioned that he had a 4.0 grade average at school and could apply for an academic scholarship. As a member of the Legends, he's the resident Mr Fix It and is in charge of providing the Waverider with maintenance.
- Heterosexual Life-Partners: Jax and Stein, although they have the occasional rough patch, are extremely close.
- Hidden Depths: He and Nate do a Fist Bump over their mutual appreciation of Ian Fleming'snovels.
- Iconic Sequel Character: Does not appear until The Flash Season Two.
- It's All My Fault: Beats himself up over Stein's death, as he convinced him to stick around instead of retiring.
- Kidnapped by the Call: When he refuses to come on the mission, Stein kidnaps him onto Rip's timeship.
- The Lancer: In Legends Season Two he becomes this to Sara. He is usually found following her around and backing her play. When she becomes wounded in episode eleven she leaves him in charge.
- Leeroy Jenkins: He ignores Stein and gets in trouble.
- Legacy Character: Succeeded Ronnie as the new Firestorm.
- Like a Son to Me: How Stein sees him. Jax takes it REALLY hard when Stein loses his life.
- Lovable Jock: He saved a crippled student during the Particle Accelerator explosion at the cost of his promising football career.
- Military Brat: His late father was in the U.S. Army.
- Mr Fix It: He was an auto-mechanic, and Rip assigned him as the go-to guy on repairing the Waverider despite it not being his specialty. Good thing Jax reads instruction manuals.
- Nice Guy: He's a friendly and helpful guy by nature, and he loves being part of a team, whether it's football or superheroes (once he gets used to the idea of traveling through time on a dangerous mission, anyway).
- The Nicknamer: Shows a tendency for this, referring to Martin as "Grey" and calling a racist bully in The 50s "Biff".
- The Not-Love Interest: Jax is the most important person to Stein among the crew.
- Not That Kind of Doctor: Rip asks him to fix the Waverider due to being a mechanic. Jax quickly reasons that he is an auto-mechanic.
- Only Known by Their Nickname: He's simply referred to as "Jax" to most of the team.
- Only Sane Man: He's by far the most normal Legend, having not been an assassin, time traveller, criminal, or genius scientist or inventor. When everyone else is debating over whether they should kill Per Degaton or just dump him in a random time period, Jax is the one who suggests just talking to the kid instead.
- Put on a Bus: After dealing with Stein's death, Jax decides to go on a sabbatical.
- Related in the Adaptation: Inverted. In the comics, he's Ronnie's Black Best Friend. Here, they don't know each other and he's merely his successor.
- Reluctant Hero: He's very reluctant about the idea of being a superhero, and even after that he's reluctant about the idea of helping Rip Hunter chase Vandal Savage through time. Stein actually ends up kidnapping him because he wouldn't willingly go.
- Salt and Pepper: With Prof. Stein. He's the Pepper of the pair.
- Sir Not-Appearing-in-This-Trailer: He never appeared in the teaser trailer in order to avoid spoiling Ronnie's death before it was revealed in the Season Two premiere of The Flash (2014).
- The Smart Guy: He's The Engineer as opposed to the scientists like Ray and Martin, or the historian like Nate.
- Supporting Leader: Sara temporarily puts him in charge when she's out of commission.
- Tagalong Kid: While he is an adult, he's the youngest member and just out of highschool.
- Team Spirit: Self-admitted.Jax: [to Stein] I love being part of a team, man.
- Team Dad: Hilariously despite being the youngest of the group. In Season Two he ends up being this. When Sara ends up playing TeamMom Jax is right behind her giving the misbehaving team members, most likely Ray and Nate a disapproving eye. If she's not the one trying to sort out the team family like squabbles its Jax.
- Token Minority: He shares this trope with Kendra Saunders and later Amaya.
- Took a Level in Badass: He is clearly getting the hang of being Firestorm much better compared to when he first started. Also even without fusion, he is found always ready for a fight.
- Transplant: He made his debut in The Flash before becoming a main cast member of Legends in his subsequent appearances.
- Trapped in the Past: He and Stein were trapped in the Medieval Era after Rip time-scattered the team during the Legends Season Two premiere.
- Two First Names: Jefferson Jackson, what else?
- You Called Me "X"; It Must Be Serious: In times of seriousness he stops calling Stein "Grey" and refers to him as "Martin" or "Professor Stein".
Known Aliases: Firestorm III, Soviet Firestorm
Played By: Stephanie Corneliussen (body) and Victor Garber (mind)
Appearances: Legends of Tomorrow
After witnessing Firestorm II in action during 1975, Vandal Savage hired Soviet scientist Valentina Vostok sometime between that year and 1986. They began creating their very own version of Firestorm, having had 10 years to research his abilities before Rip Hunter reappeared. The project to create Firestorm was dubbed "Operation Svarog", in honor of an ancient Slavic god of fire.
- Adaptational Villainy: Vostok is usually a hero in the comics.
- Bad Future: She very nearly caused one where the Soviets succeeded in creating an army of Firestorms that won the Cold War and laid waste to the world. The Legends averted this by taking back the Firestorm Matrix from her and causing her to be blown up when she's unable to control Firestorm's powers.
- Composite Character: Puns aside, the Soviet Firestorm in the comics is Mikhail Arkadin (who already appears as her ally), while Valentina Vostok is the Negative Woman. She also takes queues from Svarozhich as an Evil Knockoff of Firestorm, which is given a Mythology Gag as the name of the project to create Soviet Firestorm.
- Does This Remind You of Anything?: The forced Fusion Dance between her two components is literally forcing someone to be inside of you.
- Double Standard: Rape, Female on Male: Averted Trope. The way she talks about merging with Stein, and how she forces him to do it, brings to mind a form of rape, and it is most definitely not okay.
- Drunk on the Dark Side: She cackles with glee when all of Firestorm's nuclear power becomes hers.
- Evil Is Burning Hot: A fire based supervillain.
- Evil Knockoff: Her host body is ordered to create a version of Firestorm after her boss witnessed Jax and Stein in action.
- Gender Flip: The Soviet Firestorm in the comics is male. Said male character does appear though.
- Hoist by Their Own Petard: Forces Stein into a Fusion Dance despite his warnings of the dangers of doing it without wearing a Quantum Splicer (as was the case during Stein and Ronnie's initial merge). The move literally blew up on her face (along with the rest of her body) when Jax pulls Prof. Stein out of her.
- How Do I Shot Web?: She has little control of her powers, and Stein certainly doesn't want to give her some pointers.
- "I Know You Are in There Somewhere" Fight: A literal example. Jax calls out to Prof. Stein repeatedly during The Legends' fight with her, which succeeds.
- Mythology Gag: Being an Evil Knockoff of Firestorm brings to mind Svarozhich, who was a clone of Ronnie Raymond. The project the Soviet scientists used to create Soviet Firestorm is named "Operation Svarozhich".
- Sensual Slavs: A literally and figuratively hot Russian.
- Unskilled, but Strong: She is able to produce fire much stronger than both the Ronnie and Jax versions, but has little control of her powers.
