Rumbledome

Clearly, we are incapable of getting beyond Rumbledome.

The Rumbledome is a huge stadium in Crown City, primarily used for concerts, demolition derbies and monster-machine deathmatches. It also makes a great location for demolishing Decepticons. It's located adjacent to the refinery. It's managed by Farnum.

Fiction

2015 Robots in Disguise cartoon

Headlock and Groundpounder were drawn to the Rumbledome when they saw an advertisement for the heavy-metal rumble. They arrived as Truckalodon was demolished by Casey in Mechanosaurus, and entered Groundpounder in the tournament. The Decepticon made short work of Mechanosaurus, however the Autobots had spied what was going on. Grimlock was duly entered with Denny Clay posing as his driver, and with some wrestling tips from Fixit, they managed to defeat Groundpounder, though by then the Rumbledome was partially demolished and the crowd had fled.

Some time later, the stadium was repaired, and the band Rear Axle made a stop at the Rumbledome. Bisk, Hammer, and Anvil managed to infiltrate the Rumbledome's backstage and steal some soundboards for Steeljaw. Bisk was intercepted by Bumblebee, and although the Decepticon tried to get beyond Rumbledome, he was defeated by the Autobot, in a battle that the humans mistook as a choreographed part of the show.

"Let's get ready to Rumblebee! ... no?"

After the Decepticons overran the refinery, the Autobots detected their signals and came hurrying. The battle spilled over into the neighbouring Rumbledome, where the Autobots triumphed over their foes. Robots in Disguise (mobile game)

Notes

• The Rumbledome as depicted in the mobile game is an open-air stadium, making the Rumbledome name something of a misnomer.
