A Console Patron Unit (CPU) is a term used to classify the goddesses. Each nation's safe source of share energy is in the faith of their own patriots and the amount (piety number of followers) directly correlates to each CPU's power.
Each CPU has two physical manifestations- Human and Goddess. Each CPU possesses two names- Birth Names and Divine Names. Examples of birth names include "Nepgear" and "Neptune". Divine names are what the CPUs obtain when Hard Drive Divinity is engaged, such as "Green Heart" or "Purple Heart". Divine names are also used in a formal context by dignitaries or civilians granted an audience. Regarding their physical appearance, the divine form is similar to the human appearance but with new characteristics. In some rare cases, their appearance will change dramatically.
- The term "CPU" originated in the English script of the Hyperdimension Neptunia series. In the Japanese script, the term "Shugo Megami" (Patron Goddess) is used. Likewise, CPU Candidates are called "Megami Kohousei" (Goddess Candidate).
- In the original Japanese version of the Neptunia series, the goddesses are also referred to as "Hard" which is short for "Hardware." With that said, Console Patron Unit serves as a substitute since it carries the same general meaning as "Hard".
- However, the term CPU has recently been adopted by the Japanese script. The Term first appeared in the Japanese opening of Superdimension Neptune VS Sega Hard Girls, followed by usage in dialogue in the Japanese version of Cyberdimension Neptunia: 4 Goddesses Online.
