Wolffe, formerly designated CC-3636, was a veteran Clone Commander in the Grand Army of the Republic who served with Jedi General Plo Koon during the Clone Wars. The leader of the 104th Battalion‘s famed Wolfpack squad, Commander Wolffe proved to be tireless in his efforts against the Confederacy of Independent Systems, displaying an affinity for strategy. On his first mission with Koon, Wolffe served on board the Jedi Master‘s flagship, the Triumphant, when Koon led a task force to eliminate the Separatist warship Malevolence. While confronting the Malevolence in the Abregado system, all the troopers from the Wolfpack who were on board the ship were eliminated, save for Koon, Wolffe, and troopers Sinker and Boost. The four were rescued by Jedi General Anakin Skywalker and his Padawan, Ahsoka Tano, and Wolffe had his unit adopt new clone trooper armor in honor of his fallen comrades. Refusing to let the loss of the Wolfpack deter him from his service, he inspired loyalty amongst his men.

During the Battle of Khorm, Wolffe lost his right eye in a fight with the Sith apprentice Asajj Ventress. Although scarred and forced to wear a cybernetic eye replacement, Wolffe continued his military service to the Republic, undertaking several key rescue missions with Koon to Felucia, Vanqor, and Lola Sayu. He personally oversaw a supply mission to the groundquake-devastated planet Aleen, assisted in liberating Togruta slaves from the Zygerrian Slave Empire on Kadavo, and took part in a mission that recovered the lightsaber of the late Jedi Master Sifo-Dyas.

Fifteen years after the end of the Clone Wars, Wolffe was still alive and was living in a modified AT-TE on Seelos with Captain Rex and Clone commando Gregor. Wolffe initially distrusted the Spectres, which included the Great Jedi Purge survivor Kanan Jarrus among their number. Believing that the rebels were a threat, Wolffe sent a transmission that was picked up by the Imperial Agent Kallus. However, Wolffe came to see reason when Rex spoke up for the rebels and told him they were not a threat. Under Rex’s command, Wolffe and Gregor held back Kallus’s AT-AT walkers so that the rebels could escape. Following the battle, he and Gregor stayed behind on Seelos while Rex joined the rebellion. In 0 BBY, Wolffe and Gregor contributed to the Liberation of Lothal.
