Transformers - Tempus Exitium
Rumble is your basic street punk: Small, but always acting tough as a cover. He’s not exactly the most subtle of Soundwave’s spies, but what he lacks in discretion, he makes up for by being the brawler of the group. He talks tough because he is tough. Quick-tempered and of a generally mean disposition, he follows Megatron eagerly, as the Decepticon leader lets him indulge in destruction. Rumble has a tendency to toss out a taunting rhyme at his enemies and is, according to Brawn, a “jerk” (or at other times, a “sawed-off nerd”).
As the Decepticon demolitions expert, Rumble loves nothing more than to break things apart. His arms can transform into powerful piledrivers that, when pounded against the ground, can cause earthquakes, usually with fissures. He can be easily overpowered in a one-on-one match, though the real challenge is actually getting to him first. Even if you do, you usually need to get through his brother Frenzy either before or after you get Rumble.
? BCE (Before the Great War)
Megatron Origin 1 – Rumble worked on Mining Outpost C-12 until senator Decimus came to tell the miners that the mine was being shut down. He was witness to the Autobot guard Decimus brought with him, turn a miner in scrap after voicing his opinion about automating the mines, and also saw Megatron throw his pick-axe into Decimus’ shoulder. Megatron was attacked by the Autobot guard, but quickly killed him. After that, the entire group of revolting miners were shot down by the Autobots. Later, on a shuttle towards Penal Facility H-3, Rumble, together with Frenzy told Megatron they needed help getting off the ship. They caused a diversion by taking down a guard, which allowed the rest of the miners to capture the shuttle. Megatron eventually had them shoot down Decimus’ ship, and took their ship to Kaon, where they went into hiding.
Megatron Origin 2 – Following Megatron, Frenzy and Rumble arrived on an arena site that wasn’t done yet. Soundwave appeared, offering Megatron the use of weapons and technology. They were talking, when Megatron discovered two Autobot spies; Fastback and Bumper. Both of them were taken out by Buzzsaw, Laserbeak and Ravage, and Megatron questioned them with the help of Laserbeak and Soundwave. Soon they discovered that the Autobots were after them, and Megatron in particular. Megatron ordered Scrapper to end construction, and they left the site.
Megatron Origin 3 – Right before Megatron gave his speech that would form the Decepticons, bolt Rumble and Frenzy started arguing with Megatron about their recent modifications. Megatron made it clear that there would be no change of plan, and they would stay under Soundwave’s command.
