VGResource Pokédex Project: IDEA PITCH

[Baegal]

For the sound/sight one, it would be cool if the sound one could neutralize light/vision, and somehow lightwaves could silence a noise.
I know it doesn't make sense scientifically, but it could be an interesting balancer between these opposing beings.
Or maybe they could complement each other instead?
(Complement: Groudon/Kyogre (to an extent) + Dialga/Palkia)
(Conflict: Reshiram/Zekrom + Xerneas/Yveltal)
