The last two unknown moves will be Zygarde's two signature moves once it fuses through Mega Evolution with either Xerneas or Yveltal in order to facilitate the current needs of the environment it observes. If the environment is in need of repair, it will Mega fuse with Xerneas to create life. If the environment has become unruly, it will Mega fuse with Yveltal to destroy the offending force. Thus restoring balance to its respective environment.
Or something, I don't fucking know.
