Mizuho

Lola (Japanese: ミズホ Mizuho) is a Water-type Pokémon specialist. She is the mother of Brock, Forrest, and eight other children. She is married to Flint. For a very short time, she was the Gym Leader of the Pewter City Gym, known officially as the Pewter Gym, and she gave out the Boulder Badge to challengers who defeated her. Lola is married to Flint and has ten children. Flint left one day to become a professional Pokémon Trainer and never returned. Some time after that, Lola herself wandered away to train Pokémon, leaving Brock in charge of his many siblings. One of Lola's many hobbies is decorating.

In the Chronicles episode A Family That Battles Together, Stays Together, Brock returned to Pewter City after traveling through Kanto, Johto, and the Orange Archipelago and found that Flint was shirking his Gym Leader duties. Flint explained that the Gym was ruined because Lola had returned. Lola had totally redecorated the inside and outside of the Gym, planting a series of trees and bushes outside. She also filled the inside of the Gym with water, and decorated it with streamers and pink hearts and stars. Flint ended up closing the Gym because he couldn't stand it anymore. Brock returned home to find his mother cheerfully redecorating the house.

Lola gushed over her own work and showed off her Water-type Pokémon and said that they were much better than Rock-types. Brock demanded to know how Flint could let this happen, and Flint explained that he just couldn't say no to his wife. Lola and Flint had a rematch for the title of Gym Leader. Flint was sure he would lose due to type disadvantage, but Brock pressured him into the battle anyway. Flint's Pokémon almost ended up drowning in the match and had to be resuscitated. Flint was almost ready to run away again, but after some flirting, Lola and Flint ended up being lovey-dovey with each other and the two agreed to change the Gym to specialize in both Rock and Water-types (to their children's dismay).
