>>36523416A Pikachu and Eevee who have received BST Boosts that make them solid mixed attackers when the only things they have to worry about are other Kanto Pokemon, attacks that have incredibly broken secondary effects (Sizzly Slide guaranteeing burns effectively crippling any and all non-fire physical attackers Eevee will come across for instance), a free Not-Z-Move at some point after Brock but before Misty that's basically Z-Return if it actually based damage based on Happiness that ALSO doubles as a fat stat boost if you have a Pokemon other than your starter out, and said Gym Requirements usually ensure that you'll breeze right through the Gym.
>b-but Misty's Starmie has Scald!! Erika has a Vileplume like in Red/Blue and her levels are higher!!The Starter can outspeed Starmie and will most likely KO it in 2-3 hits even without Pika Papow or Veevee Volley, the AI will likely play retarded so Starmie will be more likely to spam Swift or Rapid Spin, and in Erika's case you have an EXP Share active at all times from the very fucking beginning of the game that gives 100% of EXP to all six of your current Pokemon, and said EXP can be significantly boosted just by making quality catches on random wild Pokemon.
