Fiction
Toy pack-in comics
Inferno, with Prowl and Ironhide, built an energon tower.
Later, Inferno, Landmine, and Prowl surveyed a hill as a possible site for an energon tower. Landmine asked Optimus Prime for permission to construct the energon tower, but the Autobot leader denied the request, citing Decepticon activity in the area. Such "activity" soon involved the Autobots when a flock of Divebombs attacked them. Faced with insurmountable odds, Inferno was forced to Powerlinx with Prowl. Megatron soon joined the attack, but Powerlinx Inferno was able to shoot down the Decepticon leader. The Divebomb attack was revealed to be a distraction when Insecticons, having absorbed all of the energon underground, erupted from the ground. Unable to handle all of the Terrorcons, the three Autobots were forced to flee. Energon Volume 2
Later, Inferno was Powerlinxed to Hot Shot when the Autobots were defeated in battle. They were saved by the arrival of Wing Saber. As an individual, Inferno was there to witness Optimus Prime welcoming Wing Saber into the Autobot ranks. Energon Volume 4

Soon after the defeat of Unicron and the reunification of Cybertron, Inferno was one of several Autobots who greeted the human delegation sent from Earth, managing to scare the crap out of a young Kicker.
Ten years later, Inferno was part of Optimus Prime's detachment of Autobots sent to investigate the mysterious attack on Mars and to help defend Earth. Landing on Mars, Inferno reported no signs of life in the aftermath of the attack. He then went on to Earth, where he helped take down several Terrorcons attacking Kicker before powerlinking with Hot Shot to destroy several more in quick succession. Cybertron City
As the Autobots prepared for further attacks on Earth, they were caught off-guard when the Terrorcons hit Lunar City instead. Inferno operated the Space Bridge controls to send his fellow Autobots to the moon, while remaining behind to guard Ocean City in their absence. Energon Stars Inferno remained on monitor duty as Hot Shot and Jetfire were tasked with shoring up the defenses at Desert City and Plains City. He detected a mysterious comet, but was unable to properly identify it before it vanished. Scorpinok Inferno continued his monitor duties and running the Space Bridge as the Autobots prepared for combat on Earth and Mars. Megatron's Sword As the search for new sources of energon continued, Inferno monitored Kicker's progress from Ocean City. He detected the Terrorcon forces zeroing in on Kicker, and sent out an alert to warn him. The New Cybertron City
As Terrorcon attacks on the Autobot installations increased, Inferno was given command of the new Cybertron City in the mountains, where he coordinated the defense against the latest attack before joining Ironhide in the aftermath of Scorponok's unsuccessful raid on Jungle City. Later, he was part of the Autobot detachment sent to reinforce Plains City, where upon arrival, he expressed surprise at the utter devastation that greeted them. Megatron had returned, and Hot Shot was mortally wounded trying to oppose him. Megatron Resurrected Inferno oversaw the severely damaged Hot Shot's recovery in an energon regeneration tank on Ocean City. He valiantly defended Hot Shot's recuperating body from Battle Ravage drones until he was nearly overwhelmed by their sheer numbers. Fortunately, Hot Shot recovered in time to help out his comrade, then together they confronted Megatron with the newly constructed copies of Megatron's sword. Megatron Raid
When Optimus Prime was being stalked by Alpha Q's new agent, Starscream, Inferno and the other Autobots worked together to shadow Prime for his own protection, despite his protests. Starscream the Mysterious Mercenary Soon thereafter, Ironhide and the others journeyed into the asteroid belt and confronted a massive ship resembling Unicron. They fought through Scorponok and the ship's defenses and managed to destroy it, but the threat of Unicron lingered on everyone's minds. Battle of the Asteroid Belt As the plan for energon towers was unveiled, Inferno successfully defended Ocean City until Doctor Jones' prototype was off the ground and basted away all the Decepticons. Energon Tower
As Jungle City came under Terrorcon attack, Inferno teamed with Kicker and Ironhide to confront the ground assault forces. Inferno attempted to teach Ironhide the lessons of patience and precision. He arranged an ambush for the Terrorcons by gathering a large supply of energon in one spot, and waiting for the Battle Ravages to strike. Next, Inferno prepared each shot before firing, making absolutely sure of a direct hit instead of blinding wasting ammo. As the Autobots abandoned Jungle City and planned to destroy it and the Terrorcons still inside, Inferno encouraged Ironhide to take the fateful shot necessary to ignite the energon deposits. Crisis in Jungle City
While searching for trace amounts of energon on the moon, Kicker was assaulted by Terrorcons. Optimus summoned Inferno and the other Autobots from Ocean City to defend against the Decepticon attack that followed. They drove off the Decepticons once Lunar City was reactivated, and an energon tower sent from Cybertron expelled a shockwave that drove off the enemy. Kicker Beware! In preparation for Megatron's comet strike on Earth, Optimus Prime dispatched Inferno to Lunar City, where he assembled the first line of defense using Omnicons and auto-gun turrets to turn against the comets. Energon Grid
As the Autobots planned out their future mission now that Earth was safe behind the energon grid, Inferno attended the preparation session to head out into space and actively stop the return of Unicron. Rodimus: Friend or Foe? He joined the crew of the newly minted Miranda II, and fought the Decepticons during their inaugural Space Bridge flight. Go for Unicron! After Kicker detected energon on an uncharted planet during their travels, Inferno piloted the Miranda II down into the atmosphere for a closer look. Unfortunately, the extreme cold caused pillars of ice to grow out of the mountains and form around the ship, trapping it in place. As the other Autobots searched for the energon, Inferno lived up to his name and turned a flamethrower on the ice in order to melt their way free. The Return of Demolishor
During the approach to Unicron, the Autobots were assaulted by the Decepticons and flying Terrorcons drones. Working together, Kicker and Inferno managed to wipe out most of the Terrorcons by using small chunks of energon like grenades, lobbing them into the Terrorcons' midst, then shooting them so they'd explode. A Tale of Two Heros Inferno was at the helm of the Miranda II as they prepared for the first attack run on Unicron. He piloted the ship through the belly of Unicron, as Megatron sent ever-shifting panels and blocks to crush their vessel from all directions. Having successfully gotten the enemy's attention, the Miranda II shot out towards a Space Bridge, luring Unicron into the vicinity of Cybertron, where a massive alottment of energon towers exploded in firepower against the Chaos-Bringer. Megatron was forced into utter retreat, and the first battle against Unicron was a victory. Battle Stations
Unfortunately, this also sent a clear signal to the Decepticons that the war had begun anew. Uprisings began on Cybertron, as Inferno and Hot Shot recognized the rebels were heading towards the special prison holding Shockblast, an absolutely insane and extremely powerful Decepticon who was forced into imprisonment after the war instead of gaining amnesty like so many others. Powerlinx Inferno and Optimus Prime raced to the detention block to prevent the dangerous warrior's escape. Alpha Q: Identity Unfortunately, Shockblast escaped right out of their grasp, using one of his guards as a living shield to make a getaway, then cutting him down the moment he was no longer useful. The fight raged outside, as Inferno and the others fought to defend Cybertron's energon towers against Shockblast and his new Decepticon allies. Shockblast: Rampage
During the peace talks between Optimus, Rodimus, and Alpha Q, Inferno briefly traveled to Cybertron before returning to Unicron's head in the company of Arcee. Survival Instincts Later he fought alongside the other Autobots in defense of Cybertron's energon towers. Each One Fights... A highly-successfuly Terrorcon raid delivered enough energon to Megatron to transform Unicron and directly threaten Cybertron. Inferno and the Autobots made an effort to breach Unicron's defenses and attack Megatron within. Unicron Unleashed
Inferno infiltrated Unicron separately from the other Autobots, taking up a sniper position to hunt for the Decepticons. He found a clear shot at Shockblast, and took it. Unfortunately, the one-eyed fiend was quick enough to throw up a shield that blocked Inferno's blast. Open Fire! The fighting that followed shook up Unicron considerably, and Inferno eventually fell out of the Chaos-Bringer's hull, but was rescued by Jetfire. Ripped Up Space

After arriving on Iron Planet, Inferno was separated from the other Autobots and captured by Megatron. Under the uneasy watch of Starscream, Megatron repeatedly tortured Inferno by branding the Autobot's faction sigil with his magic Decepticon energies (similarly to how he branded Scorponok). Although Inferno was eventually rescued by Optimus Prime, a virus had been introduced into his system, over time turning him into a Decepticon. Improsoned Inferno
Inferno wrestled with this virus as he accompanied the Autobots to Jungle Planet, unwillingly assisting the Decepticons in finding energon.

During a confrontation with Scorponok, Inferno appeared to overcome the virus and assert his true allegiance when Kicker urged him to keep fighting, Bulkhead but to ensure he would not betray his friends again, he sacrificed himself by diving into Alpha Quintesson's energon sun. Farewell Inferno
Inferno's spark was recovered, and he was reborn in a new, tamper-proof body under the name Roadblock. In his first mission rebuilt, Roadblock oversaw a flotilla of energon tower missiles sent by Dr. Brian Jones to attack Unicron's headless body. Omega Supreme
While recovering on the Miranda II from damage taken while attacking Unicron, Roadblock took to referring to his male nurse as Nurse Flare, causing Signal Flare to hotly insist that he was a medical assistant, not a nurse. He checked himself out of the medical bay early, and took part in protecting Alpha Q's planets from Unicron under Rodimus's command. Unicron Perishes

Toys
Energon

- Inferno (Deluxe, 2003)
- Japanese ID number: SC-03
- Accessories: Missile
- Energon Inferno transforms into a Cybertronic water-cannon firetruck. His spring-loaded water cannon fires a blue projectile, and can also be turned and pivoted in several directions.
- In robot mode, his large windowed chest is a small homage to Generation 1 Ironhide's appearance in The War Within. Inferno can Powerlinx with any compatible Deluxe-class or Mega-class Autobot, forming either the top or bottom of each combination.
- The main differences between the Hasbro and Takara releases is the Hasbro version uses a darker silver plastic and has several gold paint applications that the Japanese version lacks. This makes the Hasbro version marginally more accurate to his appearance in the cartoon.

- Hot Shot / Inferno Super Link Set (Multi-pack, 2003)
- Japanese ID number: SS-01
- Accessories: Missile
- In Japan, Takara released Inferno both individually and in a box set with Hot Shot. Both toys are identical to their individual releases.

- Inferno V: Volt (Deluxe, 2004)
- Japanese ID number: SC-21
- Accessories: Missile
- Like Generation 1 Grapple being a crane retool of Generation 1 Inferno, Inferno V is an extensive retool of Energon Inferno, replacing his front bumper, head, stabilizers and the entire water cannon structure with a new crane and cab. Like Grapple, Inferno V is colored mostly orange.
- The Hasbro version of this toy represents the toy-bio continuity character Roadblock, who isn't a powered-up version of Inferno.
Built To Rule

- Inferno (Built to Rule, 2005)
- Accessories: Missile
- Built to Rule Inferno was originally designed as a Built to Rule toy of Armada Rollout, who was developed with a much more solid Trans-Skeleton with larger, blockier limbs, a design that was carried on to the true Energon Built to Rule construction sets. A pressure-launched missile launcher was added onto the Rollout design to justify the change of character.
- The Energon Built to Rule line only had a limited, test market release initially in and around Cincinnati, Ohio. The sets later filtered out into some "Tuesday Morning" chain stores at drastically dropped prices.
