Possible Side Activity? Legendary Leaders?

[Alladar]

I was thinking since this is the first generation of games that let you easily have all the legendaries and there will likely be a ton of people with Dialgas and Kyogres that normally sit in boxes doing nothing for competitive...

We could have a Legendary Leader side event where you expect leaders to use at least one legendary pokemon, challengers can bring their legendaries, and maybe just no M Rayquaza (because seriously Gamefreak WTH).

Maybe if you do a legendary leader battle you get a badge and then a mark and after x marks you get a free badge? It would help people get through gym leaders faster and especially help kids who typically really want to use Mewtwo and such.

We've actually toyed a little with the idea of legendaries in battle!
It may be something that happens eventually, but is not currently planned for East 2015.

But trust me when I say, it certainly is on our minds!
