I noticed something interesting when I was exploring Challenger's Cave on Route 9! There is a girl who says if you talk to her " In the story I know, the Legendary Pokemon was training its student Pokemon". What Legendary Pokemon do you think she was taking about? Could this be hinting to a future Pokemon? Is it the event Pokemon Kerudio and its trio members Cobalion, Terrakion, and Virizion? Meaning Kerudio trained them? Speculate!
