Rumble is a fictional character in the Transformers franchise. In order to trademark the name, Hasbro referred to the Alternators character as Decepticon Rumble.

Transformers: Generation 1

The first toy for Rumble was originally released in an earlier Takara toy line called Microman. In cassette mode, the toy was able to fit inside the body of Cassetteman (who would later become Soundwave). When the line was imported to the U.S. as Transformers, the toy was released in two different colors as different characters—Rumble and Frenzy.

Rumble's colors changed over the course of Generation 1, originally being red (leading to confusion as Frenzy was blue) in the original toyline and Marvel comics. The cartoon made Rumble the blue robot instead. Dreamwave comics, IDW comics, and even the recently released Alternators toy all represented Rumble as a red robot. The Japanese dub of the original Transformers series switched Rumble and Frenzy's names around so that their cartoon appearances would match the colors of their toys.

His personality in both Marvel Comics and in the animated series was described as being a basic street punk. He was always ready for action and eagerly carried out Megatron's orders. He can cause earthquakes with his piston-like arms.

Animated series

Rumble is often partnered with Soundwave, along with other cassette Decepticons Ravage and Laserbeak. Because of his coloration on the original cartoon, he is sometimes identified as Frenzy, as the color schemes for Frenzy and Rumble were actually transposed.

Throughout the animated series Rumble was perceived as tough and full of firepower, but his fellow Decepticons, being much larger, were significantly more powerful. He gave the weaker Autobots, such as Hound, Mirage and Bumblebee hard times on the battlefield, due to their lack of warrior-like capabilities, although in one episode, Hound beat the tar out of Rumble during a huge Autobots/Decepticons battle. Due to his small size and average intelligence, he displayed a Napoleon complex and often tried to prove his loyalty to Soundwave and Megatron through tough talk and destructive tendencies.

Rumble debuted in the series opener "More Than Meets the Eye Part 1", being used by Soundwave and Starscream to destroy a power station with his piledriver arms, and later to cause a large wave that would allow the Decepticons to create Energon cubes at a nearby dam. He battled and defeated Hound underwater, although the Autobot would get his revenge later on. Rumble appeared regularly throughout the series, although he rarely had major roles, and was usually called on to create tremors with his arms (such as in "Enter the Nightbird" or "Attack of the Autobots").

He was defeated by Sludge in "S.O.S. Dinobots" when his attempt at generating an earthquake was thwarted by Sludge's own.

One of Rumble's missiles damaged Red Alert in "Auto-Berserk", plunging the Autobot into a paranoid stupor.

In the episode "Sea Change", Rumble was humiliatingly turned into a tree through magic.

He was sent by Megatron to steal the cars that would become the Stunticons in "The Key to Vector Sigma part 1".

One of Rumble's most prominent appearances was in the episode "A Decepticon Raider in King Arthur's Court". Warpath, Hoist and Spike Witwicky were battling Starscream, Ramjet, Rumble and Ravage in England. Low on power, the Autobots and Decepticons discovered a magical stone formation called the Dragon Mound and were transported back to the year 543 AD. Although Starscream attempted to take over a castle and build a new empire with himself as lord, the help of local knights and a wizard refueled the Autobots, who defeated the Decepticons. After defeating a dragon who nested in the Dragon Mound the Autobots and Decepticons and returned to their own time where they rejoined the fight in modern-day England. Here, Rumble ended up in a jousting contest atop his "steed" Ramjet.

Rumble appeared in The Transformers: The Movie, cutting off the Autobot communications alongside Frenzy, Ravage and Ratbat, before battling their Autobot counterparts. During the leadership debate aboard Astrotrain (after Megatron had been unceremoniously set adrift in space) Rumble and Frenzy were deployed when the Constructicons insulted Soundwave's leadership ability (Rumble: "Hey! Nobody calls Soundwave un-crasamatic!)" (uncharismatic)). When they tried to form into Devastator, Rumble and Frenzy used their piledriver arms to shake the giant into his component pieces.

Rumble also appeared during the beginning of the third season in "Five Faces of Darkness," but disappeared shortly thereafter.


In the Japanese anime Transformers Headmasters, Rumble made sporadic appearances along other cassettes. He was first seen in the fourth episode of Headmasters, just after Soundwave is re-built as Soundblaster.

Transformers: Cybertron

The Japanese name for the Decepticon Scrapmetal is Ramble, the Japanese name for Generation 1 Rumble. When the human Coby converts one of the Rambles into a mech body, he goes by the name Coby-Ramble, or Cobybot in the U.S.


According to an interview with producer Tom DeSanto published in issue #15 of the Transformers Collectors Club magazine, the original lineup pitched for the Decepticons in the live-action Transformers film was Megatron, Starscream, Soundwave, Ravage, Laserbeak, Rumble, Skywarp and Shockwave. Rumble did not make it to the final list; Frenzy did instead.

Transformers: Timelines

This Rumble is an alternate good version of the Generation 1 character from the BotCon exclusive Shattered Glass comic, in which the Decepticons are on the side of good and the Autobots on the side of evil. Presumably like all Decepticons of his world, he is heroic and opposed to the evil Autobots.

Transformers: Prime

Video games

In the 2010 video game Transformers: War for Cybertron, Rumble appears in the Autobot campaign, where Optimus Prime and his team must defeat Soundwave to save Zeta Prime. Rumble is one of Soundwave's minions alongside Laserbeak and Frenzy. As a reference to the original G1 incarnation, he uses the catch phrase, "First we crack the shell, then we crack the nuts inside!" once ejected into battle. The first phrase of his catch phrase "First we crack the shell" is also the name of an achievement/trophy. It involves the player getting smashed by Trypticon's hand as he falls down in Chapter 10.

In Fall of Cybertron; the sequel to War for Cybertron, Rumble once again appears as one of Soundwave's cassettes. While you play as Soundwave in the final level you can eject Laserbeak and Rumble to fight off the Autobots. He also pops up in the background throughout the game.
