Inferno is one gung-ho robot, ready and willing to roll out into the thick of any action at the drop of a hat. If the mission is search and rescue he's one of the best bots to have around, but he's even happier when called on to fight. Nothing gets Inferno's circuits going like a one-on-one with a few Decepticon trouble makers. During his down time he can generally be found hanging out with Red Alert and trying his best to keep overly-Paranoid Red out of trouble.
He appears to have a Relationship with the Fem-bot Firestar.
Inferno appeared without explanation one day as Optimus Prime explained their mission to stop the Insecticons from attacking the Nova Power Plant. He was the first to roll out on Prime's orders. During the battle at the power plant, the gun-slinging fire fighter stood by Jazz and shot down Laserbeak before they rushed off to to rescue the human pilots of a downed helicopter. After the super-powered Insecticons crushed Wheeljack and electrocuted Ironhide, Inferno sprayed fire-retardant foam on Ironhide and loaded him into Prime's trailer as the Autobots retreated. Inferno later participated in the Autobot counter attack at Iron Mountain where he and the other Autobots were buried under tons of rock. Hound was heard to complain about Inferno ending up on his head whilst they were trapped.
When the Dinobots accidentally set fire to Autobot headquarters, Inferno helped Red Alert douse the flames. Later, Inferno did his part to preserve the sanctity of the timestream by spraying cowboys with fire retardant foam. Eh...you had to be there.
Later, Inferno was ordered to guard over Red Alert as the Autobots repelled an attack by the Decepticons on the Negavator super weapon's bunker. Inferno, itching for a fight, abandoned Red Alert despite his paranoid friend's repeated requests for him to stay. Inferno rescued Red Alert when his friend was buried under rubble which had the unfortunate side-effect of damaging Red Alert's logic circuits to the point of overload. Inferno later proved his friendship to Red when he saved Red Alert from himself when the latter, in a state of paranoia, allied himself with Starscream and the Decepticons.
Transformers: The Headmasters (Japan only)
Marvel Comics continuity
Inferno joined Sandstorm and Broadside as part of a monitoring unit stationed on Earth to keep watch for the threat of super-Decepticon, Galvatron. Shortly after they arrived, the unit chased off the unrelated threat of a Furnacian Firebug, who had arrived on Earth and begun starting fires in human settlements. They exiled it to Mercury in a message pod.
When Galvatron later resurfaced, the reconnaissance team sent a message to Cybertron and joined up with the Wreckers and Decepticon Mayhem Attack Squad in confronting the time traveler. Unfortunately Galvatron had help (as if he needed it) in the form of Megatron. The Wreckers and Mayhems were torn to shreds, suffering greater than 50% losses. Inferno was one of the few survivors who limped away from the final battle, cut off from any support from Cybertron. The remaining members of the Wreckers and Mayhems pooled resources as the Survivors, living on Earth separately from the planet's active Cybertronian armies.
Inferno was present when Prowl and Grimlock were loading up their shuttles to go chase after Bludgeon and his gang of less-than-merry men. He was later killed on the planet Klo and then reactivated by the power of the Last Autobot.
In an alternate timeline, Inferno was one of seven remaining Autobots on Earth in the year 2009, fighting against Decepticon domination of the American continents. He survived the desperate attempt to prevent a nuclear attack by the rest of the world, and was last seen fighting against greater odds heroically, for all our freedoms. (He probably died immediately after that panel.)
After a new squad of Mayhems came to Earth to execute their treacherous former members, the Survivors failed to stop the Decepticon named Bludgeon from killing Catilla. After Carnivac ran off on his own to seek vengeance against the Mayhems, Inferno and the remaining Survivors hooked up with Grimlock's Earthforce in order to provide the Pretender some proper back-up. They then chose to stick around with Earthforce full time as an adjunct unit. Inferno and the Survivors were later seen on the high seas, fighting off Starscream when he attempted to hijack an oil tanker.
Later, Inferno was standing guard over the Mayhems they had captured when the Survivors first joined with Earthforce. Bludgeon, Octopunch and Stranglehold were being model prisoners. Very quiet...too quiet. As Inferno began to get unnerved by the silence, Stranglehold suddenly began pounding away at the floor like a madman, tearing it up while still they all remained totally silent. Not quite sure what else to do, Inferno turned off the energy bars and entered the cell to blast the prisoner with a pacifier ray. As soon as he did, though, Bludgeon's katana shot through his backside, summoned mentally from the storage room by its master's Metallikato discipline. Inferno blacked out as the three Pretenders casually sauntered out of their cell to freedom.
Marvel UK future timelines
In the alternate version of 2008, after Unicron's attack on Cybertron, Inferno and his good friend Smokescreen discovered Unicron's continued existence on the planet Junk, where he had enslaved the Junkions into rebuilding his body. Retreating to their ship to make contact with the rest of the Autobots, they ran afoul of the brainwashed Death's Head. Inferno was badly injured, but with their shuttle under attack by Cyclonus and Scourge in the skies over Cybertron, he was forced to hurl Smokescreen to safety through the front windscreen, so word of Unicron's survival could reach Rodimus Prime. Inferno's last act was to go out in a blaze of glory, crashing straight into the Decepticon ranks in the battle below.
Inferno was working with a squad of Autobots trying to stop Jhiaxus's Cybertronians from committing genocide on planet Ethos. Most of his team took heavy fire and apparently died, though. Inferno himself was distraught at Smokescreen's death and broke ranks to hit more of the Cybertronians - as a result, he was crushed under a collapsing building the enemy brought down on top of him.
Dreamwave comics continuity
Inferno and his good buddy Smokescreen joined up with Grimlock's Lightning Strike Coalition during the time of the Dark Ages. Some millennia later, after the Great Shutdown, Inferno was one of the first Autobots reactivated and brought around to the idea of a unified Cybertronian populace by Ultra Magnus and Shockwave. Joining Red Alert, Hoist, Grapple, Skids, and Perceptor, he became a charter member of the Autobot High Council, ruling alongside Shockwave in administrative matters while Ultra Magnus focused on more militant concerns. However, the lack of leadership experience by Inferno and most of his fellow council-beings led to them ceding more and more power to Shockwave over the years. They eventually came to their senses and joined in the insurrection against Shockwave led by Optimus Prime and the Ark's crew.
IDW comics continuity
Inferno was attending to the fire damage and chaos caused by Megatron's opening assault on Kaon when a pleasure cruiser fell out of the sky on top of him, likely killing the Autobot fire fighter.
Except he survived. During the following war on Cybertron, he was one of several Autobots Blaster would have trusted his life with. After Blaster returned to the Autobots after having been lost for millennia, Inferno was among Blaster's friends who took leave from their assignments to see "The Voice". However, after a second attempt on Blaster's life, Inferno was also one of the four Autobots under suspicion of the failed assassination. Fortunately the real (unwilling) culprit was caught, so Inferno and the others were cleared.
- Inferno (Autobot, 1985, 2003/2004)
- Japanese ID number: C-10
- Accessories: "Extinguisher Rifle", 2 fists (left & right), 3 missiles, 2 head nozzles
- Inferno transforms into a Mitsubishi Fuso firetruck. Each of his forearms contains a spring-loaded missile launcher, so he can fire his own fists or silver missiles. He is usually depicted in media has having a missile/ laser in place of a hand on his right arm. He is also armed with a small black Extinguisher rifle.
- In 2002, Inferno was re-released as part of Takara's Transformers Collection series. This time he featured tampographed Autobot symbol and blue eyes instead of yellow. These changes carried over to the Commemorative Series Inferno, Commemorative Series Grapple, and Roadhauler.
- Inferno with Hydro-Pack (Action Master, 1990)
- Accessories: Hydro-Pack, "Magna-Blast Gun"
- A non-transforming action figure with a simplified design, Inferno came with a Hydro-Pack that could be attached to his back or transformed into a large hand held Laser weapon. He is compatible with all other Action Master weapons and vehicles.
- Inferno (Autobot Hero, 1993)
- Accessories: "Extinguisher Rifle", water cannon, 2 fists (left & right), 2 head nozzles
- For Generation 2, Inferno's original toy was re-used with virtually no deco changes, adding only the "Autobot" tampograph. His forearms were retooled to remove the spring-loaded launcher mechanism (the chromed missiles from the original releases were also dropped), but he came with a large red water-shooting cannon that clipped to his ladder. Said cannon rains pain.
3D Battle-Card Game
- Inferno (2007)
- A 36-point "rare" character in the 3D Battle-Card Game's "Energon Wars" expansion, Inferno "transforms" into a red fire truck. He uses the same parts layout as Movie Bonecrusher, albeit with some parts moved around to make him more fire truck-like.
- Inferno's original toy, slightly modified, was knocked off and used as the titular giant robot in the Korean animated film Phoenix King (피닉스킹). Phoenix King was dubbed (horribly) and released in America by Digiview Entertainment as Defenders of Space, generally selling for the bargain price of $1.00. Scenes of "Inferno" from this movie were also incorporated into another bargain film distributed by Digiview Entertainment, Space Thunder Kids.
- In the late 1990s, a knockoff of Generation 2 Inferno with some yellow parts was sold in discount stores on a card reading "Transformers: Generation 3."
- The earliest pictured version of Action Master Inferno is largely different from the final version, but only upon close examination. The early version errs on the side of the original toy in color and design, while the final more closely follows the design of the animation model. Strangely, the early version has a nearly solid black block of a head (possibly to echo the ladder base in which the original's head was contained), as well as generally wider and chunky proportions.
- Inferno was one of many Transformers to be cut out of The Transformers: The Movie. His scene was cut but the credit for the character remained.
