Spar, born Alpha-Ø2 and later known as Mandalore the Resurrector, was a rogue Alpha-class Advanced Recon Commando who rebuilt the Mandalorian Supercommandos and fought for the Confederacy of Independent Systems during the Clone Wars. Alpha-Ø2 was cloned from the Mandalorian bounty hunter Jango Fett on the planet Kamino for the Grand Army of the Republic. An aberrant clone with more independence and free-thinking than his fellow soldiers, Alpha-Ø2 found after eight-and-a-half years that he had inherited the memories of Jango Fett. With the aid of Cuy’val Dar doctor Mij Gilamar, Alpha-Ø2 made his escape off Kamino in the hold of Slave I, taking the name «Spar» from what the Kaminoan trainers had called him.

Spar traveled the galaxy as a bounty hunter before the Clone Wars. When war broke out and Jango Fett was killed in the Battle of Geonosis, Spar realized that he needed to reform the Mandalorian Supercommandos and traveled to the planet Mandalore. After overcoming the pacifist movement of Duchess Satine Kryze, Spar became Mandalore and formed the Mandalorian Protectors, recruiting two hundred police from Mandalore—including Fenn Shysa and Tobbi Dala—and a dozen former Death Watch members. He took the name «Mandalore the Resurrector» as a sign that he would honor the old traditions of the Mandalorians. Hating the Jedi for their killing of Mandalorians at the Battle of Galidraan, Spar joined the war on the side of the Confederacy of Independent Systems.

The Protectors fought throughout the war at Null, New Bornalex, Kamino, New Holstice, Zaadja, and even Mandalore, where they seized the headquarters of MandalMotors for Separatist use. Spar brought new matériel to the Mandalorian cause, including Pursuer-class enforcement ships and the BL-series Battle Legionnaire droid. Their final mission ended in betrayal when Darth Sidious ordered the Protectors to capture Senator Padmé Amidala on Norval II—a mission that proved to be a Republic ambush. Only three survivors walked away from the battle: Shysa, Dala, and a shell-shocked Spar. Spar left the post of Mandalore but stayed on the planet Mandalore for some months longer. During his stay, he joined with the colleagues of Kal Skirata to retrieve information that could help cure the rapid aging of clone troopers. He eventually disappeared into the Extrictarium Nebula, where, years later, Ailyn Vel—the daughter of Boba Fett—mistook him for her father and killed him.
