Here's why:
* Ruby's regional Pokedex: The Hoenn region in Ruby does not have any wild Electric-type Pokemon available.
* Evolution: The only Electric-type Pokemon obtainable in Ruby is Pikachu from the starting trio. You can then evolve Pikachu into Raichu, but you need a Thunderstone.
Here's how to get Thunderstones in Ruby:
* Trade: You can obtain a Thunderstone through trading with another player.
* Secret Bases: You can find Thunderstones as items in other players' Secret Bases.
To get Electric-type Pokemon in Ruby, you need to:
* Trade: Trade with someone who has caught Electric-type Pokemon from other regions.
* Cheats: You can use cheat devices to obtain Electric-type Pokemon.
Remember, it's generally best to stick to the Pokemon available in your game's region for a more authentic experience!
