Beyond the fact that they've operated outside the Milky Way previously ?I'm I just going off how the Galaxy police is in the actual canon. which is they basically keep order though out the Milky Way Galaxy . in actual canon there's nothing mention about them deal with other galaxies so in the actual canon they only have jurisdiction in the Milky Way Galaxy not other galaxies . intergalactic is actually a better word to use when referring to multiple Galaxies, because the word Galactic refers to normally just one Galaxy.
name Galaxy Police doesn't even seem applied something like Intergalactic stuff. ICPO is based on Interpol. I just don't see how law enforcement group with a name like the Galaxy police could possibly have jurisdiction in other Galaxies. I look at one of NPC profiles and it mentions quadrants of the galaxy ( which I believe refers to the Milky way Galaxy ).
I didn't see any mention of other galaxies anywhere in the prolife. I was going to make ICPO to cover multiple galaxies not just quadrants in the same galaxy. Praxat and Qaztoh Home world Qacriea is located in the Tadpole Galaxy which is not a neighboring Galaxy to the Milky way. it's out side of the Galaxy Group the Milky Way is a part of.
the only way a law enforcement group with the title of Galaxy Police could possibly have jurisdiction over other galaxies is if the word Galaxy in there name refers to galaxy super clusters not just only the Milky Way Galaxy. a galaxy super cluster is cosmic structure that consists of anywhere from hundreds to thousands of galaxies. a galaxy group is a group of galaxies, a galaxy cluster is a collection of galaxy groups , and a galaxy super cluster is a group of Galaxy clusters.
so in from what read online about how cosmic structures work I believe the order goes like this Universe > Galaxy Super Cluster > Galaxy Cluster > Galaxy Group > Galaxy > Star System.
Cuz they have.
