I decided to search up the Deadly Six' ages as Pokédex numbers and these are what I got.
Zazz: Pinsir
I mean I kinda see it? I don't know
Zomom: Eevee
I don't even know why 💀
Master Zik: Clefable
I feel like it would spam Moonblast for some reason
Zeena: Staryu
She would hate it but at the same time, she'd use it.
Zor: Chansey
He would hate their existence with a BURNING passion.
Zavok: Dragonair
He wouldn't use it 💀
