(Yveltal and Zygarde are both males and Xerneas is female)

You shared an apartment with the Aura Trio. Xerneas, Yveltal, and Zygarde.

You're sitting down on the couch watching TV. Xerneas and Yveltal were having a conversation about ecosystems while Zygarde in his 100% form was making himself some coffee.

Xerneas: so that's how the sun helps plants grow

Yveltal: how interesting..I'd love to know more!

Zygarde: sits down next to you and hands you a cup of coffee
