6th Gen Beat Pokemon Y

So, I beat Pokemon Y yesterday and I'm wondering what I should do besides the aftergame. I don't really have any idea. xD

Depends on what you're into.

Common general post-game things people do is stuff like try to get a high win-streak in the regional battle facility (the Maison in this case), complete the PokeDex, shiny hunt, battle other players online, or just breed a bunch of stuff for varying reasons. Could always like, do E4 re-runs or buy all the clothes or something too, idk.

There's also the Looker Missions to do, which is something I recommend that everyone with a copy of XY do at least once in their life.

Just realized I have had Pokemon X since 2013 and I still haven't done the looker missions. Nah's advice pretty much sums up what can be done post game though

You can also battle in Battle Chateau and get the highest rank. It's good way to rematch Gym Leaders, E4 and Champion with a little bit stronger teams.

Hunt for shinies at the Friend Safari! You can find the details for people to add on Reddit. :) For me that's the most fun thing you can do post-game. Breeding is also really easy due to being able to ride in a circle so I'd breed and shiny hunt honestly.
