The beginning of the SPD incarnation had the A-Squad Rangers lost in space when their ship crash, but they were discovered and rescued by the B-Squad Rangers in the episode, "Resurrection." It was during the rescue that Charlie is revealed as the Red Ranger when she de-morphs. In the end of the episode, the A-Squad Rangers hold Commander Cruger captive, with Charlie revealing that they are taking him to Emperor Grumm.
The following episode, "Endings (Part 1)," begins with Charlie and the rest of the villainous Rangers revealing their alliance with Grumm, while Cruger is imprisoned. Charlie shows her arrogance when it comes to the B-Squad Rangers, and while Grumm warns her that their foes are not to be underestimated, the evil Charlie continued to claim that she and her squad will easily defeat them. The sets of Rangers battled after Charlie called out the B-Squad, and the traitorous quintet beat down the B-Squad; all the while, Charlie laughed evilly and taunted her foes. When the B-Squad activated SWAT Mode, the A-Squad summoned a Zord left by Grumm to use against their heroic counterparts.
The B-Squad defeats the A-Squad with the SWAT Megazord, and in defeat, Charlie snarls defiantly at Jack. Charlie and the rest of the A-Squad Rangers are judged and imprisoned for their treason.
