Millary is another in the business Pokemons, and the reason for that is because of her own ability she has, he udders unlike other Miltanks are able to produce various flavors of MooMoo milk, her white one produces normal milk flavored, the pink one is for strawberry, the brown one tastes makes chocolate and the yellow one makes vanilla one. She is pretty much trying to make the msot of them and make sure evryone enjoys the flavors while also trying to buff and keep everyone healthy with her milk. She is quite tomboyish always trying to pick a fight for any reason to prove she is a powerful Miltank...

Someone no one understand is how she keeps her clothers and glasses when she does her signature Roll-out move in fights.
