Several months after the destruction of Rishi Station, Fives, with Echo, joined the 501st Legion in a number of battles throughout the galaxy. While stationed aboard the Resolute, Fives and Echo were tasked with taking inventory of the Star Destroyer's supplies, as well as guarding the ammunition.^[8] When the Republic learned that the Confederacy was about to invade Kamino, Fives, along with Echo, Kenobi, and Skywalker, were dispatched to the world to prepare for the impending attack. While Kenobi and Skywalker met with Shaak Ti and Kamino Prime Minister Lama Su, Fives and Echo roamed through Tipoca City's military complex. The two clones soon spotted their old clone trooper friend, 99, who was glad to see them, but questioned Hevy's absence. When they revealed that Hevy had sacrificed himself to save the others on the Rishi moon, 99 showed the two Hevy's medal, and told them that Hevy had given it to him. Once Fives and Echo told 99 about the suspected Confederate invasion of Kamino, 99 departed to the facility's weaponry room to gather weapons for the clone troopers. Soon after the Confederacy began its assault on Tipoca City, Fives and Echo met with an ARC trooper in a docking bay at the military complex.<sup>[11]

Once there, Commander Cody and Captain Rex joined the group and told Fives, Echo, and the clone cadets that they were going to fight off the droids. However, the clone cadets disagreed, due to their training being inadequate. Fives tried to boost the clone cadets' confidence, though the cadets still remained hesitant about engaging the droids. 99 entered the conversation by telling the clones that he knew where the complex's armory room was: if the clones could gather enough weaponry and supplies, they would be able to hold off the droids. After gathering the supplies, the clones repelled Grievous's droid forces, which attempted to enter the barracks. Fives and the clones began to fire at the droids, and lured them inside the barracks room. The clones took defensive positions behind crates as the droids continued their pursuit.[11]</sup>
