Acid Storm is an evil Seeker jet from the planet Cybertron.


Acid Storm was created from the remains of Ransack by Darth Grievous. Darth Grievous covered Ransacks dead body with a black mist which transforms the dead body of Ransack into Acid Storm. After the birth of Acid storm he became leader of the Rainmakers which is a group of Jets that create Acid Rain. Despite his intelligence, data gathering skills, and potential charisma, Acid Storm prefers to wallow in anonymity as just one of the Rainmakers, a cadre of specialized Seekers who have the capability to manipulate localized weather patterns to create acid rain. He is a part of Darth Grievous's forces on Cybertron.

A member of an obscure squad of Seeker air warriors known only as "The Rainmakers," Acid Storm is known as an individual only to his teammates and a very few others. He is highly intelligent, eager, and dedicated utterly to the Seeker cause. He has a talent for marshalling vast amounts of data, as well as a way with words that would make him a powerful speaker. However, he prefers to remain anonymous, as part of his team.

His acid rain had caused chaos everywhere and his acid rain destroyed many cities on many planets.

He was punished for the defeat at Christophsis by Darth Grievous but survived.

Acid Storm was controlling a Star System until the Autobots saved the planet from the tyranny of the Seekers.

In the final episode he fight his last stand on Korriban but he was defeated by the Autobots. He went into exile after the Transformers Wars.

Dark future

In Darth Grievous's evil vision of the future Acid storm used Acid rain to weaken those Autobots and finally was turned into stone by Darth Grievous.

Powers and Abilities

His hyperion-3 blasters can seed natural clouds with a highly destructive form of acid rain. He is armed with cluster bombs, missiles and can transform his hands into lightsabers for melee combat by retracting his hands and an emitter for the energy saber projects the blade.

His alternate mode is an F-15 Eagle which is also armed with lasers.

Acid Storm Toy

  • Acid Storm (Deluxe, 2008)
    • Accessories: Left & right missile launchers, 2 missiles
Universe Acid Storm is a redeco of the Classics Starscream mold, transforming into an F-15 Eagle fighter jet, though with a canopy like that of an F-14 Tomcat. He comes with a pair of spring-loaded missile launchers that can be mounted on his biceps or used as hand-held weapons in robot mode, and are attached under his wings in vehicle mode.
This toy was also used to make Classics Skywarp and Timelines Thundercracker (and their Henkei! Henkei! redecos), and retooled to make Classics Ramjet, and Timelines Dirge and Thrust and Gentei! Gentei! Thrust and Dirge.


Acid Storms birth from Ransack is similar to Cyclonus's creation from a dead Skywarp.
