Alpha-99 "A'den"

"'We're stranded. No one will ever find us out here!'""'If there's one thing the general's taught me, it's to never give up.'"―Sergeant Mire and Alpha-99 after crash landing on a Felucian moon

Alpha-99, nicknamed "Naastar" was an Alpha-class Advanced Recon Commando serving the Grand Army of the Republic during the galaxy-wide conflict known as the Clone Wars.

Early Life and Training
Alpha-99, like any other clone, was born and raised on the watery planet of Kamino. He adopted the name of "Naastar", meaning "destruction" in Mando'a. He underwent extremely brutal training, being an elite Advanced Recon Commando. He was locked up in stasis shortly after his training was complete, despite protesting against it.

Battle of Kamino
"'Men, today we fight for not only the Republic, but for all of our brothers here at Kamino ― we fight for our home!'"―Alpha-99 to his men shortly before the invasion started

Naastar first saw action during the Battle of Kamino, where he was taken out of stasis with the rest of the Alpha-class ARCs to defend their home from the Confederacy of Independent Systems. In the battle, he led a platoon of thirty-six men to a hangar, where they would proceed to hold off huge forces. The platoon would ultimately succeed, leading them to search for Sith Acolyte Asajj Ventress after hearing of Commander Colt's death. Naastar would split up from his men, heading off for the DNA chamber. His platoon would surround Ventress after finding her on a landing platform, where Jedi General Anakin Skywalker would duel her, leading to her escape. Following the battle, Naastar would be assigned as a captain in the 505th Attack Battalion.

Battle of Geonosis
"'Commander! Get a medic, the commander's down!'"―Alpha-99 calling for a medic after the 505th loses its commander

Sometime later, the 505th Attack Battalion would be deployed to the world of Geonosis, where they would attempt to take a major separatist stronghold. It was here that the newly-appointed Jedi General Fron Narkus would lead the 505th. As the battalion advanced through the battle field toward their destination, sniper droidekas would roll from on top of the stronghold, which would lead to the loss of the battalion's commanding officer. Despite this setback, the Republic forces pushed forward, and entered the lower levels of the base. Narkus and a few platoons of his men would blow out several reactor rooms, then arm the base with charges. Following the battle, Narkus would appoint Naastar as his second-in-command, and the commanding officer of the 505th.

Invasion of Sluunist IV
"'Sir! It looks to be a Separatist invasion!'""'What are Separatists doing here? Call back all patrol units and prepare for battle!'""'Right away sir!'"―Alpha-27 and Naastar shortly before the Battle of Sluunist IV

The 505th would later deploy to the ice world of Sluunist IV in the outer rim, where they set up a listening post. While there, Naastar became acquainted to fellow Alpha-class Advanced Recon Commando Alpha-27 "Flamer", sharing similar views of the war. Droid forces would unexpectedly begin an invasion, landing just short of the base. General Narkus would try and defend the base with the 505th, but with the unprepared attack and patrol units far from base, they suffered a heavy loss and were forced to retreat without nearly a hundred patrols.

Several companies of the 21st Nova Corps would later retake the base, and bring back nearly fifty lost patrols back to the safer world of Coruscant, where they would undergo treatment from numerous diseases. This left a devastating casualty count on the 505th, but enough clone trooper privates would be recruited to make up for it.

Campaign of Ortonis Draal
"'Hold your fire! We're firing at the wrong people!'"―Naastar to his men after realizing that they were firing at Republic supporters

Naastar would take all of his men to the mid-rim and overpopulated capital city of Ortonis Draal. They would be accompanied by the 104th Battalion and an unknown legion featuring pink markings. The Republic forces would break through the Separatist blockade and make it to the planet, only to realize that the Draal people had just sided with the Confederacy of Independent Systems. A skirmish in the skies began, with Clone Z-95 Starfighters and Low Altitude Assault Transports combating Vulture Droids and Draal V-927 Assault Starfighters. The fight would soon take way to the ground, where a massive battle would ensue. The Republic would successfully take over a small portion of the planet's capital on the first day of the campaign, setting up scouts and patrols. The clone commanders suggested a retreat, being reinforced by the two other Jedi Generals. Narkus convinced them otherwise, believing that Ortonis Draal was too important to lose.

It would be on the second day that a large army would attack the Republic forces early in the morning. In the battle ensuing, Naastar had found out that these citizens were against the Separatists and had rebelled against Ortonis Draal's Prim Minister through an intercepted holo-message. He ordered the clones and Jedi Generals to stand down, and surrendered to the Ortonis Draal Rebels. They would later explain that they were Republic forces and not Separatist forces.

On the third day of the campaign, the Republic forces would press forward onto the capital's center. Clones would hold off droid and Draal forces around the city while several squads of rebels would raid the Prime Minister's office, killing him when he refused to surrender. This would result in mass chaos, leading to the successful capture of Draal's capital city, and ultimately the entire planet. It was on this day that Alpha-27 was listed as missing in action. He wouldn't be seen again until the Battle of Korggh.

Battle of Mon Cala
Several weeks after the capture of Ortonis Draal, the 505th Attack Battalion would be assigned to aid in the Battle of Mon Cala. It is unknown why General Narkus was not present, but it is presumed that he was assigned to another battle. The 505th would aid Jedi General Anakin Skywalker and Senator Padme Amidala as a security force in case negotiations went wrong. That exact thing happened, leading to a fierce battle as the Quarren chieftain Nossor Ri believed Prince Lee-Char was too young to be the Mon Cala king. Things got so intense that Jedi High General Kit Fisto had to arrive with reinforcements, leading to the death of Separatist commander Riff Tamson and the retaking of the watery planet.

Battle of Korggh
"'Naastar... and I thought that Alpha-class ARCs were smart.'""'Just shut up and hand me a weapon already, Deviss.'"―Commander Deviss and Naastar after the 327th began their attack on the lab

Spending some time off-duty on Coruscant, Naastar decoded an intercepted and secretive holo-text sent to Coruscant from the outer-rim world of Korggh. It simply stated ''"Subject is alive. Experiments beginning. Calls himself Alpha-27 or Flamer." ''Believing this to be a message on his friend and brother Alpha-27, Naastar decided to investigate with General Narkus. The two took the Purge, to explore the unknown world of Korggh. Deciding to trust the coordinates on the holo-message, the two made the jump to hyperspace to Korggh.

The planet had a bizarre climate ― there were sixty-five days of sun shining over an ordinary world, and three-hundred days of huge snowstorms and flurries. Of course, the Purge landed on one of the snowstorm days. As the two tried to explore in the small flurries, they were surrounded by specialized BX-Series Droid Commandos, and quickly taken into custody.

The two remained imprisoned on the planet for an entire week before Narkus managed to escape, receiving help from a scientist at the laboratory in which they were imprisoned. He would free Naastar, and the two would track down Alpha-27, who had been missing in action. They managed to contact the Republic, and went into hiding in a secret vent shaft under the lab.

The 327th Star Corps would later arrive on Korggh, resulting in a major battle between scientists and droids of the Techno Union and the clones. The three hidden would emerge and help in overtaking the laboratory. It is unknown what happened to the scientist who helped Narkus, but it is presumed that he died. Flamer later called him "a brave soul" for helping the Republic.
