- "Yes, I know how the Kaminoans did it. They used our genes against us, the ones that make us bond with our brothers, make us loyal, make us respect and obey our fathers - that's what they manipulated to make us more likely to obey orders. They had to remove what made Jango a selfish loner, because that makes a bad infantry soldier, and you can tell from the Alpha ARCs that the Kaminoans weren't wrong. But there's one thing I don't know yet - and that's how they controlled the aging process. That's the key. They robbed us of a full life span. But we will not be defeated by time, ner vod."

Numbering only twelve, the Null-class Advanced Recon Commandos were the first clones of Jango Fett created by the Kaminoan cloners, and the prototypes for the Grand Army of the Republic. They were deemed a failure by the Kaminoans and were not put into mass-production. However, Mandalorian mercenary Kal Skirata saved them from termination by the Kaminoans and later adopted all of them.
All of the Nulls were named after Mandalorian warriors.

The Kaminoans attempted to enhance the Fett genes, but of the first 100, twelve were shown to have 30% higher intelligence scores. They refused to follow orders, and were thus deemed unacceptable. The Kaminoans originally intended to "recondition" or terminate the 12 "defective units". Six Nulls were terminated by the Kaminoans and the other 6 were saved from destruction by Kal Skirata, a Mandalorian training sergeant hired by Jango Fett to train clone commandos. The remaining 88 acceptable units became the Alpha ARC's and the template for the cloning process.
Kal volunteered to train them as "black ops" commandos, named them, and taught them their Mandalorian heritage, sequestered from the other clones throughout their training. Even before reaching two years of age, Ordo and his Null brothers had already undergone flash instructions and live ordnance tests, where they obtained unmeasurable high scores. After completing their accelerated growth they trained in Mandalorian military and survival combat to kill and destroy by any means possible.
During training, the Nulls experienced near-death torture to train them in resisting interrogation. The mercenary Kal Skirata taught his clone troopers a technique of resisting interrogation by shutting out reality to become someone else who wasn't in your terrible situation. One way to achieve this was to visualize putting the pain and fear in a box, or concentrating on its physical reality so minutely it fragmented and ceases to register; another method was to imagine you were somewhere else. One could also focus on the next moment one could bear to think about, like the next meal, second or step, time after time until the ordeal was over. Mandalorians were trained to endure torture.
They also had special training for all types and essentials of warfare like assassination, black ops, anti-terrorism, covert ops, espionage, slicing and even medical knowledge. Their training was furthered by Kal, who taught them how to handle a wide assortment of weapons, ranging from blaster rifles to Verpine sniper rifles and hand to hand combat. They also ate food that only contained nutrients. Later in their training they learned the skills of maneuvering in zero-g.
They were also drilled codes or oral commands whether personal ones like Kal Skirata or mandatory by their higher ups, like "Check", an oral command that had been drilled into the commandos by Kal, to instantly make them stop what they were doing, and as part of their education and psychological training, the Nulls, like all clone troopers, were required to adhere to the Command Code, a set of guidelines that governed a clone's behavior and every action during their growth. Hence, every clone was obliged to obey every aspect of the Code without question, doubt or hesitance.
They received special training that allowed them to act without thinking. They claimed it was similar to the Jedi's use of the Force. Some of them even learned genetics to reverse the aging process.
Life during trainingEdit
Under Kal's supervision, the Nulls were separated from the other clones throughout their training where the other clones only ever saw the Nulls around Tipoca City when they were stealing equipment or sabotaging systems. In particular, Darman of Omega Squad remembered the Nulls scaling the supports of the huge domed ceilings, swinging around hundreds of meters above the floor and placing blaster fire to within centimeters of the Kaminoan technicians. At some point, Fett's unaltered clone son Boba Fett angered the Nulls by saying that his father could beat Kal whenever he wanted. Ordo retaliated by sticking Boba's head down a refresher.
Under Skirata supervision they learned to use their fierce independence, innate creativity, and physical superiority in combination with their training in advanced combat, weapons and vehicles to become virtual one-man armies. Though peerlessly efficient, the Null ARCs were quite unpredictable by clone standards, and loyal only to Skirata.
During the early stages of the clone army's development, Jango Fett and his Mandalorian military advisors advocated the creation of clones capable of handling covert missions too delicate for the standard units.
Before the gestation process began, the Kaminoans tampered with Fett's DNA to ensure that the clones were primarily dominated by behavioral genes that emphasized certain qualities such as loyalty, aggression, independence and discipline in order to guarantee that the army would be more docile and less independent than their template.
To achieve the desired results, the Kaminoans altered the clones' ageing process, so that each null would age at twice the rate of regular human beings. At the age of ten, a null would resemble Jango Fett in his early twenties, and was thus fit and prepared for combat.
Their genetic structure gave them higher intelligence, better perception and eidectic memory—allowing perfect photographic recall. During training, their intelligence tests scored thirty-five percent higher than other commando types and developed immeasurably high scores in training. The intense training and genetics gave them mental capabilities beyond that of standard clones.
Their physiology was greatly improved—they were stronger, faster, taller, and also heavier than basic clone troopers.
During training each clone developed Jango Fett's own Concord Dawn accent and speech patterns, though this trait was common to the flash-learned standard clone troops, as well.
When the Kaminoans first began the cloning procedure, they had produced twelve prototypes, designated as Null-class Advanced Recon Commandos. Due to the extreme modifications to their physiology, only half of the test subjects survived their gestation process. However, the "enhancements" that were made to the Fett genome left the survivors handicapped with erratic behavior and an inclination toward disobedience, this made there loyalties tense- either they would die for you, or you would end up dead.. Kal Skirata, a former Mandalorian warrior who had been brought to Kamino to assist in the training of a special unit, concurred with the Kaminoans' rationale behind "modified" troopers; an "unaltered" Jango Fett was not the ideal infantry soldier. Disappointed with the unsatisfactory results of their wayward creations, the Kaminoans deemed 12 of the first 100 prototypes as complete failures and intended to terminate them.
Kal Skirata's intervention, along with Fett's support, prevented the clones from being liquidated. As a result, Skirata was charged with training the prototypes as intelligence units. Due to the Kaminoans genetic tinkering, Mereel and the other Nulls had very intense loyalties and like his brothers, Mereel was loyal only to Kal Skirata.
Some of the side effects where that clones developed high sensitivity to minute personal details. They also had a peckish appetite, and a sweet tooth, which Skirata theorized might be due to their maturation, and the metabolic need to fuel the rapid aging.
The Null ARC's were also known as Skirata's private army. Despite the fact that their loyalty and their reliability to the Jedi was constantly in question, the Nulls' unique skills compared to the rest of their brethren was undeniable, and thus they and Kal Skirata were reluctantly tolerated in the Grand Army, if only to ensure their cooperation during the war. The Null ARC Troopers worked in the Special Operations Brigade of the Grand Army. It should also be noted that all Null ARC's were officers, except for Null-12. When asked why he was only a Sergeant by one of the Omega Squad commandos, A'den replied, "I preferred to be an NCO. If it's good enough for Kal'buir, it's good enough for me."
Two Clone Intelligence units, Null-6 and Null-10, were the troopers who located General Grievous's hiding place on Utapau near the end of the Clone Wars. The information was sent to Kal Skirata first and the intel was traced to the Supreme Chancellor's Office. Since the trace was obvious Skirata witheld the information from his superiors pending an investigation when a diplomatic package was received from Utapau informing the Senate of Grievous's location.
Though they worked for the Grand Army of the Republic, Kal Skirata had them keep alert for evidence leading to the location of Kaminoan Chief Scientist Ko Sai, so Skirata could find out how to decelerate the aging process so as to give any clone a full life span.
The experience of developing Null ARC troopers contributed much in the production of the Alpha-class Advanced Recon Commandos. During the Clone Wars, the Null-class and Alpha-class ARCs harbored a grudge against each other. Whereas the Alpha-class ARCs saw the Nulls as an embarrassment and shame to Jango Fett's legacy of a fully Republic-loyal clone army, the Nulls viewed the Alpha-class ARCs as even more stubborn than Jango and often referred to Alpha-class ARCs as "Alpha Planks", nothing special, ordinary ARC troopers. However, the highest ranking Null, Captain Ordo, managed to retain a professional relationship with Alpha Captain Maze (A-27), although the two were known to have at least once injured the other.
