Twins (ROTF)

The Twins are a couple of redneck-lookin' 'bots from the Revenge of the Fallen franchise in the live-action film continuity family.

I grabbed me a chair and said "Watch 'im, folks, 'cause he's a thoroughly dangerous man!"

When a spark splits into two separate sparks, the resulting two Cybertronians are considered twins, with an incredibly close bond. One such division yielded Skids and Mudflap, a pair of doofy-looking, hyperactive chatterboxes who refer to themselves simply as the Twins.

The inseparable pair spends more time fighting with each other than paying attention to anything going on around them. They like to think they're hard core, but when their guard drops, it turns out they're basically a couple of robot rednecks. Still, they can hold their own in a fight, and they are eager to show Optimus Prime just how skilled they are. Whether this will end up getting them killed is another question.

Each twin can transform into smaller separate vehicles or combine for a single, more durable alternate mode. Upon first arriving on Earth, the twins took the form of a beat-up old ice cream truck, but later scanned a couple of slick new Chevy cars for disguises.

Fiction

IDW comics continuity

The Twins briefly had a shared alternate mode.

The Twins received Optimus Prime's transmission for Autobots to come Earth and help defend their new home from Decepticon reprisals. They met up with Arcee and Sideswipe and landed near Mission City, making their way to a junkyard with a homing beacon Prime's Autobots had left after the destruction of Megatron and the AllSpark. After a short period of training on Diego Garcia, it was announced that the Twins would be joining the other new arrivals in helping to counter the Decepticon incursion in Shanghai Alliance issue 4

Revenge of the Fallen film

After NEST was deployed to Shanghai, the Twins were the first to be deployed, patrolling the streets and taunting any hiding Decepticons to come out and "suck their popsicle". When Sideswipe tried to make a break for it, the Twins cut him off, forcing him to turn a corner toward a dead end...and jump through an apartment building. While Arcee's components jumped through the hole he had made, the Twins decided to go around the building. However, the turn was too fast, and Mudflap lost control. Although he took full blame for screwing that up, Skids still punched him out. It's combat, what's wrong with him?!

After returning to Diego Garcia, it was decided the Twins would take separate alternate modes, and a green Trax and red Beat were provided. Both Twins were impressed, and Mudflap announced he would be taking the green. Skids disagreed, and a minor scuffle followed, as Skids called the green.

When multiple Decepticon contacts were detected on the East Coast of the United States, the Autobots immediately went to counter them without NEST. Optimus Prime and Bumblebee went to rescue Sam Witwicky, Mikaela Banes, and Leo Spitz from Megatron, Starscream, and Grindor. While Optimus took Sam to the nearby Pine Barrens, Bumblebee rejoined the rest of the Autobots and headed to reinforce Optimus. Unfortunately, by the time they got there, Megatron had already killed Prime, and the Twins served as escort when Bumblebee took the three teens to hide in an abandoned prison.

As Leo Spitz started to have a freak out over what was happening, Skids wondered what they would do with the "shrimp taco". Mudflap suggested they simply pop a cap in him, toss him in the trunk, and forget about him. Leo told the two "bumper cars" that there would be no killing. An unimpressed Skids told him to get a haircut and wine to his boyfriend. That evening, Sam asked the Twins if they could read the symbols he was seeing. They identified them as old school Cybertronian. Unfortunately, the Twins couldn't read the symbols, and weren't that much into reading anyway. When Leo came back, the Twins still poked fun at him, with Mudflap saying his panic attack was because he was a pussy. Leo however, knew of someone who might be able to help them, and the Twins accompanied Bumblebee and the group to New York City, where the source turned out to be Seymour Simmons, former agent of Sector Seven, who in turn lead them to Jetfire at the Smithsonian National Air and Space Museum. Jetfire in turn teleported the group to Egypt (an experience the Twins had no desire in repeating anytime soon), and told them of The Fallen, the solar harvester he sought, and how the Dynasty of Primes hid the Matrix of Leadership needed to activate somewhere on Earth.

As Sam continued on his quest to find the Matrix, in the hopes that it could somehow revive Optimus, the Twins continued their supporting roles. As they tried to evade some police, the Twins transformed to robot mode and hid in between some buildings. Skids described it as "blending in with the landscape, like a ninja", and Mudflap told him to shut up. As they made their way to Giza, Skids continued his attempts to blend in, only to run right into Bumblebee.
