Det finns inga bevis inom huvudfilmen och TV-kanonen hos en klonrooper som inte följer Order 66 (på grund av att de implanterades med en " inhibitor chip " garanterar sin lojalitet).
Förmodligen det närmaste vi får är i Clone Wars TV-serien där vi träffar en ödemarkklon som heter Cut Lawquane . Eftersom han gömmer sig från imperiet och stöder Jedi tror jag att vi rimligen kan anta att hans chip redan är skadat på något sätt och att han skulle ha vägrat Order 66 om han fick den.
Annat i boken EU ser vi i Dark Lord: The Rise of Darth Vader som inte alla klonerna följde ordningen 66. En hel grupp blev skurk på grund av deras kärlek och personlig lojalitet mot deras Jedi general.
“Word has reached me,” Palpatine was saying, “that a group of clone troopers on Murkhana may have deliberately refused to comply with Order Sixty-Six.”
Vader tightened his hold on the lightsaber. “I had not heard, Master.”
He knew that Order Sixty-Six had not been hardwired into the clones by the Kaminoans who had grown them. Rather, the troopers-the commanders, especially-had been programmed to demonstrate unfailing loyalty to the Supreme Chancellor, in his role as Commander in Chief of the Grand Army of the Republic. And so when the Jedi had revealed their seditious plans, they had become a threat to Palpatine, and had been sentenced to death.
On myriad worlds Order 66 had been executed without misfortune-on Mygeeto, Saleucami, Felucia, and many others. Taken by surprise, thousands of Jedi had been assassinated by troopers who had for three years answered almost exclusively to them. A few Jedi were known to have escaped death by dint of superior skill or accident. But on Murkhana, apparently unique events had played out; events that were potentially more dangerous to the Empire than the few Jedi who had survived.
“What was the cause of the troopers’ insubordination, Master?” Vader asked.
“Contagion.” Palpatine sneered. “Contagion brought about by fighting alongside the Jedi for so many years. Clone or otherwise, there is only so much a being can be programmed to do. Sooner or later even a lowly trooper will become the sum of his experiences.”
