Lanturn and Manectric are good Electric-type options. However, Lanturn comes only after you get Surf as a Chinchou in Routes 124 and 126. It does evolve quickly from where you obtain it and gets a good STAB combination.
But it does require grinding though, so does Electrike even though it's obtained early-game. Both have slow growth rates, so I'm not telling you to use those. Pikachu Its.
In my opinion what makes the best electric type is based on your team. Want a fast glass cannon like raichu/manectric for sweeping? Want a duel type for coverage like Lanturn? Lanturn is a beast since it covers weakness to ground as a electric type and ice beam covers grass. However any fast pokemon with EQ or a powerfull grass move eats Lanturn for breakfast.
I like electabuzz since it can. List of all the Electric-type Pokémon from Pokémon Ruby, Sapphire and Emerald. The strengths and weaknesses of the Electric type in the Pokémon games, and a list of Electric-type Pokémon.
Community content is available under CC. The Electric type (Japanese: でんきタイプ Electric type) is one of the eighteen types. Electric-type moves are super effective against Flying - and Water-type Pokémon, while Electric-type Pokémon are weak to Ground.
For Pokemon Emerald Version on the Game Boy Advance, a GameFAQs message board topic titled "go with which electric?". If you want to use an actual electric type, and it has to be one that you can get in Emerald, here are what I would consider: Raichu Base Sp. Attack stat: 90 Base Speed stat: 100 Decent moves aside from Thunderbolt/wave: Substitute + Focus Punch, Brick Break.
Manectric Base Sp. Attack stat: 105 Base Speed stat: 105 Decent moves aside from Thunderbolt/wave: Crunch, but only through breeding. Ralts > Kirlia > Gardevoir line is broken as hell and can win you the game entirely Electrike > Manectric is best Electric type in terms of accessibility and power.
Electric type is super necessary since Water and Flying types are very prominent throughout middle and end game. Who do you think is the best Electric type in Emerald?
