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 , 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 soldiers . 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 droid s , 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 , in that he wanted a version of the 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 from . 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 Wookiee s 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 game .
