If I breed a Pokemon using 2 mons from previous games, will it still be legal in tournament play?

Question

For example, if I transfer a Froakie and a Ditto from XY to ORAS, and I have them breed in ORAS, will the baby Froakie be legal for use in an event such as VGC?

I'm not sure about how the tournament eligibility rules work.  However, if the rules restrict to Gen 6 games, then that includes X, Y, OR, and AS.  All 4 games are part of Gen 6.  As such, any Pokemon that originates from any of those 4 games will have the blue pentagon on their summary page.

As for your more specific question, regarding the offspring...  The breeding is taking place in OR/AS, so the new Pokemon created will therefor be OR/AS Pokemon, regardless of their parentage.

Answer 1

Yes, it will be legal because it was hatched in an ORAS game. It doesn't matter what generation the parents are from.
