In Galactic Force, Cruger wasn't happy when Bridge retired from SPD early to marry Anna Thomas. He also wasn't happy when the Galactic Force Power Rangers defend town Riverside. Cruger revealed that both Jocelyn Phillips and Kayla Thomas were too young to be Power Rangers and insulted them. Until Kayla stood up to him and called him a jerk. Which began their conflict. Later on, he insults Kayla's necklace (unaware it belong to her late mother) and orders her to remove it, saying it looked ridiculous. The offended Kayla and she left. Bridge asked Cruger about his problem with Kayla's necklace. Then he explains to Cruger that Kayla's necklace was a present from her late mother. After hearing this, Cruger wanted to aplogized to Kayla. After the Galactic Force and S.P.D. teamed up to battle the Alliance of Evil, Cruger apologized to Kayla for being a jerk to her and offending her necklace and the two finally buried the hatchet.
Cruger and former SPD cadets travel back in time to stop Grumm from teamming up with Master Xandred with a plot to destroy Earth. When they meet the Samurai rangers, Cruger had strong mixed feelings for them. In a battle with moogers, Cruger ordered the Samurai rangers to remain at the Shiba house while SPD battle the moogers. Despite Cruger's orders, Ray and the other rangers enter the battle, saying to him that this was their battle and SPD came here to catch Grumm, not moogers and Xandred. After the battle, Jaycee Thomas, the older sister of former ranger, Kayla Thomas, recognized Cruger and the cadets. She tells them that they teammed up with the Galactic Force Power Rangers a few years ago. Cruger had developed friction with Jaycee's sister, just because their cousin, Anna had a relationship with Bridge Carson. Rather than telling them about his feels about the relationship, he took his anger out of Kayla. The Samurai rangers and Jaycee's father were dismayed about Cruger's attitude towards them.
