JOLLY NATURE CALCULATOR
Natures weren't part of the series until Generation III (Ruby & Sapphire), so Red & Blue doesn't have them. Every stat is calculated from base stats, IVs (called DVs back then), and Stat Experience alone. If you're looking for the Jolly nature's stat effect, switch the game filter above to any Gen III or later title. That said, the concept still helps with planning teams for remakes like FireRed & LeafGreen or HeartGold & SoulSilver, where natures do apply.
BEST JOLLY NATURE POKEMON
Outpacing the opponent by one point can flip a match. Jolly adds 10% Speed and lowers Sp. Attack, which physical attackers don't mind. For Red & Blue, Aerodactyl, Mew, Cloyster, and others all run Jolly in competitive play. There's no way to set natures in Red & Blue. You'll lock in Jolly when catching or breeding in Ruby/Sapphire or later.
