Alpha - 15

"We are not mindless soldiers, we are Alpha's. We have the ability to think on our own, and to choose to obey or not. What this new Empire is doing... is not right, and we know it." ― Alpha - 15 to his Alpha brothers during Order 66

The Clone Wars
Alpha - 15 was created on Kamino, one of the first hundreds of Clones created with the rest of the Alpha Class ARC's after the failure of the Null Class ARC's. Alpha - 15 went through specialized training, and was trained to resist interrogation even through torture.

Alpha - 15 was trained under Jango Fett's personal tutelage. Although Alpha - 15 had the ability to think for himself and had an unaltered mind unlike his newer brethren, Alpha - 15 is extremely loyal to the Galactic Republic.

Alpha - 15 was first deployed during the First Battle of Geonosis where he was tasked with eliminated a Confederacy of Independent Systems' leader. He carried out his order letting nothing stand in his way, and leaving no survivors and gaining the nickname "Wrath", and soon after his success he was immediately deployed to save a near failed operation from being doomed after a squad failed to complete their task. Having succeeded in all of his operations, Wrath was used and deployed in the toughest of tasks where the regular Clone Trooper would most definitely fail. Wrath also became the Commanding Officer of Special Operatons Brigade. Having worked with numerous Jedi he once thought as incompetent, he now respects their decisions which cause him to defect from Order 66 after it was commanded.

The Galactic Civil War
When Order 66 was first given, Wrath was sent to eliminate a few Jedi that the Republic's Troopers failed to eliminate. Alpha - 15 was going to carry out this order despite his respect for the Jedi, until he saw Clone Troopers attacking the already injured Jedi he was tasked with eliminating. He then learned that the Clone Troopers were under some kind of mind control, and this whole army was made to eliminate the Jedi from the start. Wrath took it upon himself to get these Jedi to safety, far out of reach from what would soon become the Galactic Empire.

After he defected from the newly formed Galactic Empire, he fled to where the Mandalorian Rebels were, eventually siding with The Rebellion, after the Mandalorian Rebels allied with them. He then remained with the Mandalorians after the War was finally over.
