I have a bunch of theories and headcanons and I'm sure you do too! Let's hear 'em!
-(MPJ) Ginger's company is in league with Team Rocket
-(Golden Boys) Pokemon Basketball was a precurser to the Pokeathalon
-(DPA) Koya was, at some point in the planning process, supposed to be Silver
-(P7) Actual Team Galactic has no knowledge of Io. She got a bunch of spare uniforms and tries to pass herself off as a regional leader but knows very little about them other than what they look like, which is why her agents are allowed to do things like date and why she wears her hair just down. Though if they *did* know about her, she's one of the few people that Charon would view as a threat if only because her goals are nearly identical to his own.
-(Special) Eusine has ADHD
