Rumble crash landed on earth with all of the other Decepticons during the battle to return Megatron from Hoover Dam. He was separated from his twin brother Frenzy. Now Rumble needs to stay undercover during his mission and hope that one of the Autobots (or humans) don't detect him.
About this creation
Rumble all kind of started when I was bored and was just playing with Legos. I saw that I had a ton of the Exo-Force robot hands. I connected a lot of them, and saw that it kind of looked like a Transformer arm or leg. After that, I just scavenged a bunch of hinges and stuff, and before I knew it, Rumble was born.
