If two Pokémon on the field have Dark/Fairy aura, do they stack?

Question

I'm max raid hunting Yveltal in The Crown Tundra and me and my teammates have come across a Ditto quite a few times and have taken it along with us. When it transforms into Yveltal it gains Yveltal's ability and it activates like Yveltal's does. Will Dark moves (along with Fairy for Xerneas) be boosted 66% in power instead of just 33%?

I hope the question makes sense. With the 120 maximum characters, it is not easy. I know the question is terrible but I couldn't think of other ways of writing it, if someone wants to take it down (or offer a better way of writing it) please do :(

This is what I wanted to put:
When a Ditto transforms into Xerneas/Yveltal and gains its ability, if Xerneas/Yveltal are on the field with Ditto, will their ability (Fairy/Dark Aura) boost Fairy/Dark moves with even more strength?

Answer 1

The effects will not stack multiple times if more than one Pokémon has this Ability.

Fairy Aura and Dark Aura

Hope I helped!
