What fire type should you get in emerald if you have a water type in the start?

If you start with a Water-type Pokémon in Pokémon Emerald, it's best to choose a Fire-type that can complement your team effectively. A good option is to catch a Torchic, as it evolves into Blaziken, which offers strong Fire and Fighting-type moves. Alternatively, you can catch a Numel in the early game, which evolves into Camerupt and provides solid Fire and Ground-type coverage. Both choices will help balance your team against various types of opponents.
