CPU aims to be a more thematically faithful adaptation of Tokumei Sentai Go-Busters than its official Power Rangers counterpart, "Power Rangers: Beast Morphers". It does this by maintaining more of the spy and tech motifs of its source material, as opposed to Beast Morphers which mostly ignored them in favor of having more of an animal theme.
CPU's story also aims to be more of a sequel than RPM. It achieves this by incorporating RPM sequel elements from the very beginning, as opposed to Beast Morphers which seemed to tack them all on during the last few episodes.
CPU is the first season to feature a team primarily comprised of college students. This was done in order to make the season more relatable to an older audience, and also serves as a clever subversion of the "teenagers with attitude" trope of many prior seasons.
