electric Pokemon
Fire type Pokemon or fire type moves beat electric Pokemon.
Electric
Ground is super-effective
electric and grass types
Only ground-type moves can super-effectively attack an electric pokemon.
Ground Pokemon can defeat electric Pokemon.
In Pokemon certain types can beat others and here are my examples: Water beats Fire, Fire beats Grass, Grass beats Water, Dark beats Ghost, Water beats Electric, Water beats Ground, Water beats Rock, Grass beats Rock, Grass beats Ground, Fighting beats Grass, Flying beats Grass, Physic can beat Grass, Ground beats Fire, Fire beats Steel, Fighting beats Dark, Bug beats Dark
Electric and Grass types. There is a three Pokémon pinnacle composed of Fire, Water and Grass types. It's like paper, scissors rock. Fire beats grass, grass beats water and water beats fire. The electric type is sometimes considered to wriggle its way into the pyramid. Other three-Pokémon pinnacles also exist in the games, (example Psychic, Fighting and Dark types)
No, If in any Pokemon game electric beats ground, I've seen EVERYTHING. Ground beats Electric though.
Use a good Electric-type Pokemon such as a jolteon or flaafy, ampharos or mareep. Use the same electric type Pokemon you used for gym leader Falkner. Hope I helped!
Nothing else does x2 or more damage against purely electric pokemon, but electric moves only do half damage to dragon, electric, and grass pokemon.
