Bertha

she is the elie four person, I guess! Well, Bertha has ground-type pokemon, so do not have a electric pokemon or he'll be KO. So, use water or grass types to fight it. She has the toughest of hers called Hippopowdon in DP. (Diamond and pearl.) and she had Quagsire. Water-ground. Torterra is the best at this. Any grass is the best for Quagsire. Bertha had ;v 57 or over pokemons in DP. And platinum. Well, she is the second elite four, and then it's FLint, the elite four fire-type. And he's the third.
