Wrecker

"Wrecker" was a clone commando who served in the Grand Army of the Republic during the Clone Wars.

Biography
In 19 BBY, Wrecker was deployed to put down an insurrection on Yalvik Prime as part of Clone Force 99. During the insurrection, the Wrecker cut off the queen's stinger while she was still alive. Much to the horror of his comrades, the Yalvik males attempted to mate with the soliders. The clones proceeded to fight their way off Yalvik Prime to respond to a communique sent by Clone marshal commander CC-2224 "Cody".

The communique summoned the squad to Anaxes, where the Republic was fighting a drawn-out battle against Separatist forces commanded by Admiral Trench. Clone Captain CT-7567 "Rex" deduced that Trench had gained access to his strategy-generating algorithm, which had been studied in great detail by Advanced Recon Commando CT-1409 "Echo". Although Echo had been listed as killed in action at the Citadel during the Battle of Lola Sayu, Rex speculated that Echo had been carrying the algorithm on his person during the battle. In order to retrieve the algorithm and undermine Trench's advantages on Anaxes, Clone Force 99 would have to infiltrate the Separatist command center and steal the algorithm.

Despite some squabbling between the "regs" of the 501st Legion and the supersoliders of the Bad Batch, the mission to steal the algorithm was a success. Although the squad didn't find evidence of the algorithm being stored on the premises, they discovered that the command center was receiving live signals from Skako Minor. Rex deduced that the live signal was evidence that Echo was still alive, and was being held captive by Separatist forces.

Personality and traits
Wrecker's unit, known as Clone Force 99 and nicknamed "The Bad Batch", was comprised of "defective" clones with desirable genetic mutations. In Wrecker's case, his mutations granted him enormous superhuman strength, which enabled him to lift a wrecked LAAT gunship away to recover a wounded comrade trapped underneath.

Wrecker was loud and brash, and prone to expressing his opinions in a very palpable manner; his short temper made him dangerous to friend and foe alike. He had a deep passion for explosions and destroying enemy material, including battle droids, with his bare hands. His only major weakness was his fear of extreme heights.

In combat, Wrecker was known to use a Z-6 rotary blaster cannon, rocket launcher, commando knife, and DC-17MBR.

Behind the scenes
George Lucas had a very specific vision of the Bad Batch were he wanted a version of the The Dirty Dozen with clones. Dave Filoni sketched their appearances which Brent Friedman and Matt Michnovetz used to imagine the Bad Batch's voices and personalities. Matt and Brent worked with Dave to flesh out the characters and their story where Wrecker would be based on something akin to the Hulk from Marvel Comics. Directors Steward Lee and Bosco Ng who are big Marvel fans likes to direct Wrecker the most like in scenes where he gets to rampage like the Hulk. Dee Bradley improvised Wrecker's voice the most and inserted gung-ho things like loud grunts and shouts.

Wrecker was to appear in A four episode arc written by Michnovetz which starred the Bad Batch which now included "Echo", alongside Yoda on Kashyyyk. At the "Untold Clone Wars" panel at Celebration Anaheim, Dave Filoni talked about the plot of the arc. He revealed that the characters would ride on "giant ape lizards", that were holy to the Wookiees in a religious way. In one scene Tarfful would ask the tree spirits for permission to go into battle against the enemy, which was a Trandoshan and the Separatist Alliance. To get the enemy out of some of their cities they would have to burn some of the trees. The Clones had no problem with it, but it was upsetting to the Wookies. A part of the arc would be about the Clones and the Wookiees finding a common ground to fight the separatists. A story reel clip was shown at the panel, which showed the Bad Batch and other Wookies riding on the "ape lizards" and battle against a new beast that was based on Kinraths from the Star Wars: Knights of the Old Republic game.
