You Don't.
Ditto or another Empoleon.
In my opinion, Empoleon is better.
Since Empoleon is a Water and Steel type Pokemon. So Fire, Fighting, Ground Pokemons are effective when battling Empoleon.
Barry has an Empoleon in the TV Show.
You a can a card got get 4 empoleon in.
Empoleon is not a legendary Pokemon. It is the final evolution of Piplup, one of the starter Pokemon in Pokemon Diamond, Pearl, and Platinum.
Empoleon is the 3rd and final evolution of Piplup, the water-type starter Pokemon for all 4th Generation Pokemon games. While catching Empoleon is impossible, leveling up a Piplup (and evolving it as needed) to level 36 will net you an Empoleon.
In Pokemon firered you can't, but in Pokemon leafgreen you can get it then trade it to Pokemon firered.
Empoleon...
There is no Pokemon convention in firered.
choose a piplup as a started Pokemon
In Pokemon Indigo Prinplup is the Pokemon that evolves into Empoleon and it will evolve into it at Level 36 however Prinplup would've evolved from Piplup at Level 16.
