Honestly, i saw that coming, you tend to have the same oppinion as Digger, who said the exact same thing when i asked him.

Basically, they're the best friend and guardian/mentor of the main protagonist's child, who are more of a parental figure to them than their actual parent, because the latter is mostly busy saving the world from evil. Both are the loners of their respective teams (said teams' purpose being that they try to protect the solar system/planet earth from any and all alien threats), albeit Pluto because it's her lonesome duty, and often desires to have someone to talk to, while Piccolo chose that out of his own free will, and prefers being alone, and you can often find them on a location ascosciated with time, as Sailor Pluto is the asigned guardian of the Gate of Space-Time, while Piccolo is the current resident of the Lookout, which houses the Time Chamber. Both of them were born/reincarnated for a specific reason, as Pluto was born (or rather, reincarnated as i'm specificallyusing her current version) with the specific purpose of preventing anyone from using the Gate of Space-Time which she quite successfully does, while Piccolo is the reincarnation of his 'father' King Piccolo, born to finish what he started, which was thwarted early on. And lastly, both of them had a switch of allegiance at some point in their respective and highly popular anime/manga series, which was due to being under the control of that story arc's primary villain, albeit Piccolo started out evil who became a hero early on, while Pluto started out as a villain who fell under Sailor Galaxia's control much later into the story.
