Acid Storm (G1)
| This article is about the Generation 1 Decepticon. For the Cyberverse Decepticon, see Acid Storm (Cyberverse). |
- Acid Storm is a Decepticon from the Generation 1 continuity family.

Acid Storm is something of an oddity among the Decepticons. He's more than happy to stay buried in the ranks, a largely anonymous soldier among a sea of very similar bots, rather than try and make a big name for himself. This is somewhat baffling, as his intelligence, data gathering skills, charisma and ability to manipulate localized weather patterns to create acid rain could possibly propel him up the ranks.
But for whatever reason, he stays in his role as one of the Rainmakers rather than striking out on his own.

Early in the war, Acid Storm was among the Seekers who led Orion Pax's hostage negotiation party to Bludgeon's base in the Rust Spot. Omega's Conundrum
Three years after Megatron was defeated on Earth, Acid Storm was among those Decepticons who managed to escape the human homeworld and was now under the command of the (self-proclaimed) Decepticon leader Starscream. However, with the lack of resources, poor morale and Starscream's weak leadership, the Decepticons largely collapsed into anarchy and resorted to cannibalism with not enough energon to go around. After another pointless patrol, Acid Storm and Sunstorm dejectedly sat in front of what remained of the ship that carried them to the asteroid that they now called home. All His Engines

When Hot Rod finally tracked the Decepticons to their asteroid, Acid Storm was the first one to detect the Autobot craft but did not have time to plan a counter-attack himself. While he was still panicking, Shrapnel used the base defenses to blow the Autobot out of the sky, causing pieces of it to fall on them in the process. The two Decepticons then went to search the wreckage for anything useful, only to find that Hot Rod was still alive, and heavily armed to boot. Acid Storm was quickly taken out of action by a shot to the back. Heart Like a Wheel Once Megatron was finally repaired, he took back leadership from Starscream and held an impassioned speech to Acid Storm and the others that roused their spirits once more. Spotlight: Megatron
Later, Acid Storm was one of the many Decepticons in Autobot captivity on Cybertron. The Autonomy Lesson He was put to work alongside other Decepticons in "waste reclamation". Devisive Later, Acid Storm was among a Cybertronian crowd recruited by Starscream to pressure Prowl into revealing one of his secret discoveries below ground on Cybertron. Later underground, they witnessed a Titan declare that Starscream was the Cybertronian destined to unite their whole race. He and the other Cybertronians celebrated afterwards with Starscream. All Good Things

When Megatron appeared for the first time since the war ended, Acid Storm and the other Decepticons stopped the Autobots from executing him on the spot, then realized that this was their chance to oust the Autobots and return to the good old days. Starscream tried to stop them from rioting with rousing speech about change, but Acid Storm told him to stuff it and walked off with his mates to torch some buildings. City on Fire They then marched straight to the Autobot prison, where they made short work of the guards and liberated Megatron from captivity. The Verge As Megatron led the Decepticons in a new attempt to conquer Cybertron, Acid Storm participated in the battle with the defending Autobots. Plan for Everything The battle ended with a Decepticon defeat, and all Decepticons who wouldn't renounce their faction were banished into the wilderness, including Acid Storm. Shockpoint
After the destruction of Iacon, Acid Storm became one of many down-trodden Decepticons living in a ghetto outside of Metroplex. When Optimus Prime stopped by the ghetto only to be harassed by an angry mob, Acid Storm joined in but tried to stop Sparkstalker from needlessly angering the Prime. City of Steel Acid Storm was also involved in a second attack on Prime when he visited the ghetto again. First Contact

On the streets of Iacon, Acid Storm accepted one of the Camiens' pamphlets on the Word of the Primes. Still, he remained a Decepticon at his core, and attended the rally held by Needlenose and Galvatron for the Decepticon cause. The Transgressors As Galvatron addressed Acid Storm and the united listeners, the Decepticon army was officially reborn on Cybertron. Aphelion Acid Storm and the others marched on the Space Bridge and used it to attack the Autobots trapped behind Blackrock's onyx field aboard the Ark-7. Lagrange As the Ark-7 crashed to Earth, Acid Storm and the Decepticons prepared for their invasion but found themselves facing Autobots Perihelion and the People's Liberation Army Mecha Force. Acid Storm was freaked out to see the Chinese kill one of his comrades. Once Upon a Time on Earth

Acid Storm met back up with Galvatron's forces on the submerged Nemesis and was deployed to defend the ship from Optimus Prime and Soundwave's combined forces. When Superion and Victorion began to give the enemy an advantage, Galvatron manipulated the Enigma of Combination source code spread across the entire planet to merge Acid Storm with several other troops into Galvatronus. It's Beginning To And Back Again A short time later, Superion's efforts broke Galvatron's control of the Enigma and Galvatronus de-combined. Acid Storm was left dazed and was abandoned as Galvatron and Astrotrain made their escape. As Above...So Below He was later seen being taken into custody by the combined Autobot and Decepticon force. White Light

He was evidently eventually released, and selected by Thundercracker to play the lead role in his biopic of Starscream. However, Acid Storm ended up leaving the project due to dissatisfaction with being painted gray every day and the constant rewrites, forcing Thundercracker to take on the role in his stead; as he left, Acid Storm was frustrated to learn that they could've been digitally recoloring him the whole time. Starscream: The Movie
After Soundwave had been outed as Horri-Bull's killer, Acid Storm led the manhunt for the outlier before he noticed Starscream sneaking around with the Decepticons asking the ex-chancellor to resume leadership of the faction. Endless Forever After giving a small speech and Nemesis had flown off, Starscream agreed and led the Decepticons away to draw up new plans. Unforgivable As Starscream outlined his plans to regroup with the scattered Decepticon cells, Acid Storm felt compelled to point out that they were holed up in Metrotitan's corpse which Starscream claimed made for a good metaphor.

Star Trek vs. Transformers

When World War III consumed Earth, the Decepticons fled the blighted planet aboard Trypticon, trailing the Autobots aboard Fortress Maximus. When the two Titans reached Cygnus Seven, the Decepticons attacked, the battle sending Maximus hurtling into the planet and causing everyone to fall into stasis lock. Eventually, the Federation moved onto Cygnus Seven with a survey team accidentally rousing Maximus's autonomic systems. By random chance, the repair beam first struck Megatron who proceeded to revive the other Decepticons and lead an attack on the surface.

Kre-O

- Acid Wing (Kreon Micro-Changer, 2013)
- Collection: 2
- Bag number: ***** 70
- Accessories: Logo brick (2013), logo plate (2016 only), 2 clip-on rifles
- As part of the second wave of blindpacked Micro-Changers, Acid Wing is a Kreon mini-figure with parts to rebuild him into a bright green jet. He shares the same parts and construction as the preview wave's Sunstorm, though his instructions do not have you use the extra jet-mode bricks to assemble a funky two-handed double blaster for his robot mode like you do with Sunstorm. You can anyway, though. We're not here to tell you how to play with your imagination-expanding building-brick-based figures.
- This Collection was still in circulation at "dollar" stores and drug stores up through 2015. They eventually lost the individual-identifying bag codes, but other changes were hidden inside the bag. The 2015 releases replaced the 2x4 logo stand-brick with a new 3x4 logo plate. The Kreon was also given the slight retooling to the arm seen in the 2014 Kreons, making the "cuff" parts more sharp-cornered and better adapted to being used as studs. Some of the add-on pieces may also be slightly off-color, possibly due to a change in factories in mid-production.
- Acid Wing (Kreon Micro-Changer, 2016)
- Collection: 2
- Accessories: Logo plate, 2 clip-on rifles
- In 2016, Collection 2 was re-released in a whole new production run for Dollar General stores in the US as part of a large collection of re-released Kre-O sets. But where most of these releases are nigh-identical to the originals, the re-released Micro-Changer blind-bags use the almost-entirely-retooled 2015 Kreon, with slightly-differently-hued plastics than the originals. (It is possible for some of the add-on pieces to be in the older hues.) Acid Wing's torso tampograph underwent a slight color change, replacing the dark gray with solid black, though the leg tampos remain dark gray.
- Sadly, this release has no individual-identification code on the bag, requiring you to use the feel-through-the-bag method or just buy blind and hope.
Bot Shots

- Nemesis Prime / Megatron / Acid Storm (Multi-pack, 2012)
- Series: 1
- Number: Super Bot 006
- Fist strength: 420
- Blaster strength: 905
- Sword strength: 285
- Part of the first wave of Bot Shots Series 1 three-packs, Acid Storm is a redeco of Starscream, transforming into a teeny fighter jet very very vaguely like an F-22 Raptor, with a spring-loaded automatic transformation to robot mode triggered when his nosecone is pressed. He has a "spinner" in his chest that shows his three attack types and power levels. As a "Super Bot", he is cast in translucent green plastic, and has more lopsided stats. He comes with Megatron and Nemesis Prime.
- This mold was also redecoed into Skyquake, Thundercracker, Sunstorm, Quickslinger, and Autobot Firestrike, and was retooled into Skywarp.
Masterpiece

- Acid Storm (2013)
- Masterpiece Acid Storm is a Toys"R"Us-exclusive redeco of MP-11 Starscream (himself a heavy retool of MP-3 Starscream), but without the coronation gear. He transforms into an F-15 Eagle fighter jet, and features numerous built-in gimmicks, such as an opening panel at the top-center of the jet, adjustable thrust vectors, a sculpted radar hidden in his nosecone, and an opening canopy. In robot mode, he features missile pods hidden in his chest.
- For accessories, his non-firing cannons are attached to extending armatures so that they don't have to be removed for transformation, but they each have a 5mm post, and can be easily detached via ball joint. He also comes with two missile racks which peg via 5mm post onto ports on his wings, provided the cannons (which normally mount there in vehicle mode) are removed. Also included is a pilot figurine that can fit in his cockpit, and he additionally has a clip that is intended to mount underneath the cockpit and hold the Megatron gun initially included with 20th Anniversary Optimus Prime/Masterpiece MP-1 Convoy. Finally, he comes with a two-piece stand, which has two peg-holes to store two of his weapons, and can be configured for either robot or vehicle mode.
- On the sides of his cockpit, he sports tampographed names of a pilot and a co-pilot: "MSGT. [Master Sergeant] B 'Vicious' Vala" (after Hasbro designer Bobby Vala[1]) and "SSGT. [Staff Sergeant] Etipsone" (after graffiti artist Etipsone[2]).
- Acid Storm's instructions neglect to mention numerous steps of his transformation, such as the fact that the strut his nosecone is attached to is on a slide joint that allows it to slide into the cockpit more and help compact his kibble backpack. It also fails to mention the fact that he has heels hidden in compartments just in front of his thrusters, and that his tail-fin/rear wing assemblies are also on slide joints, allowing them to slide up and allow his toes and heels to both touch the surface at once. To make matters worse, his instructions only tell you how to transform him into vehicle mode... despite the fact that he's packaged in vehicle mode.
- Acid Storm, along with fellow Masterpiece, Soundwave, was first released in limited numbers in conjunction with San Diego Comic-Con 2013. Acid Storm was later made available in TakaraTomy's markets as a "USA Edition" of sorts, still exclusive to Toys"R"Us. While the figure itself was unchanged, the packaging was altered to change his ID number, among other things. Common to both versions is a designated number marking him as part of the Thrilling 30 line.
- Acid Storm's original deco would have been significantly different, such as featuring a different pilot and co-pilot ("MSGT. Bill 'Brawlin' Brawley" and "SSGT. Mark 'Tag' Maher"), and being far more busy. He would have had numerous additional tampographs, such as a reference to him being part of the "924th Rainmakers", a reference to a "Toxitron
Weapons System", "Bringing the Pain Rain", and even Rainbow Dash's cutie mark![3]
- The original MP-3 version of this mold was redecoed into MP-6 Skywarp and MP-7 Thundercracker, while the MP-11 version of this mold was also redecoed into MP-11S Sunstorm and Transformers Masterpiece Thundercracker.
Generations
Thrilling 30
- Acid Storm with Venin (Legends Class, 2014)
- Accessories: 2 cannons
- Part of the seventh wave of 2012-onwards Generations Legends Class toys, Thrilling 30 Acid Storm is a redeco of Legends Class Starscream. He is roughly the same size as a Cyberverse Commander Class toy. Based on a Guido Guidi seeker concept for IDW Publishing, Acid Storm transforms from a hybrid F-15/F-22 style jet. He features a fold out front landing gear, 5mm-compatible hands, and back/roof, and has 3mm-compatible upper arm ports. He comes with two removable cannons that have both 5mm and 3mm pegs.
- Acid Storm is partnered with Venin, a redeco of Waspinator, who can transform into a wasp-er, a cicada, a robot with 3mm-compatible hands, and a gun with 5mm handle. He has an autotransformation feature that folds up his wings when his gun barrel is extended.
- This mold was also used to make Generations Combiner Wars Thundercracker and Skywarp.
Alt-Modes
- Acid Storm (Alt-Modes, 2016)
- A redeco of Alt-Modes Starscream, Acid Storm is a super deformed toy whose body transforms into a jet when the Decepticon faction symbol on his head is flipped. He was blind-boxed and available in one of the first three cases of the toyline.
- This mold was also used to make Alt-Modes Thundercracker, Skywarp, and Sunstorm, and would have been retooled into Dirge.
War for Cybertron: Siege
- Seeker Acid Storm / Seeker Ion Storm / Seeker Nova Storm (multipack, 2019)
- ID number: WFC-S
- Japanese ID number: TBA
- Japanese release date: TBA
- Accessories: 6 "HPI Null-Ray Laser Launchers"
- This Siege three-pack version of Acid Storm is a redeco of Starscream from the same line, transforming from a heavily Generation 1-inspired robot to a Cybertronian 'tetrajet' based on the Seekers' appearance in "More than Meets the Eye, Part 1" and back; although the jet mode has the robot legs sticking out from the undercarriage. He includes two "HPI Null-Ray Laser Launchers," which can mount on his upper arms, or under the wings in jet mode, and comes with the other Rainmakers, all based on their appearance in "Divide and Conquer". All three feature battle damage and use the smirkless head sculpt used by Starscream and Skywarp.
- This set was made available at general retail in US Target stores without prior announcement from Hasbro. Release venues elsewhere have yet to be announced.
Merchandise

Tiny Titans
- Acid Storm (Tiny Titans, 2016)
- Series: 6
- Number: 3/12
- Part of the sixth and final assortment of Tiny Titans blindpacks, this version of Acid Storm is a very small, soft-plastic figure of him in robot mode... and is an entirely different mold from normal Tiny Titans Starscream. Amazing!
- He includes a collectible card that renders him in the 2015 Robots in Disguise styling. The card includes a scan-badge for the Robots in Disguise mobile game, which unlocks a random amount of Energon "currency" and a randomized bonus power-up item.
Notes

- Acid Storm isn't solid green in every shot of "Divide and Conquer"—in the monitor shot he first appears in, he has grey intakes and a green-grey upper chest that matches his helmet. Oddly enough, the intakes are one of the areas that were left the basic green on his Universe toy.
- Although explicitly based on the green Rainmaker from "Divide and Conquer", Acid Storm's near-fluorescent green in the cartoon was specifically toned down to fit better into the quasi-realism of the 2008 Universe toyline.
- Acid Storm's basic camo pattern was designed by Aaron Archer, a relatively rare occurrence for the time given Archer's high hierarchical status within Hasbro. The specifics of Acid Storm's Universe deco were then fleshed out and finalized by designer Bill Rawley.
- According to Hasbro's BotCon 2008 panel, Acid Storm was originally to be named Rainmaker, then Acid Rain, but those names didn't clear legal.
- Acid Storm's "hyperion3 cannon" is based on one of the email addresses of Transformers fan Matthew Karpowich, aka "Monzo", much as Acid Storm's bio itself is based in part on him (notably the data-gathering aspect). This is the second Universe toy to shout-out to him, the first being Onslaught.
- Acid Wing's instruction sheet spells his name as a single word, Acidwing. We go with what's on the bag-back, the two-word version.
- The Kre-O Character Encyclopedia bizarrely categorizes Acid Wing as a Predacon. No, we don't know either.
Foreign names
- Japanese: Acid Storm (アシッドストーム Ashido Sutōmu)
