Its pretty common for rangers partner pokemon to become popular favorite pokemon and even unofficial mascots in their respective towns or regions, especially after a bigger mission.
For example, plusle and minun can be seen just about anywhere in fiore, despite only having those two in the entire region, from sewing patterns to art, or fiore region posters.
Or ukulele pichu was already an unofficial mascot before everyone saw him riding on the back of legendary pokemon on a daily basis, and fighting gods.
The exception is kellyn and kates pokemon because no one can agree on which is their partner.
