Pokemon Showdown is a popular online battle simulator for the Pokemon games. It allows players to build their own teams and battle against other players from around the world. The simulator is designed to mimic the experience of playing the actual Pokemon games, with all of the same rules and mechanics.

To get started, players can create an account on the Pokemon Showdown website. From there, they can build their own teams by selecting Pokemon from a database of hundreds of creatures. Each Pokemon has its own unique set of moves and abilities, so players can customize their teams to suit their play style.

Once a team is built, players can enter into battles with other players. The battles take place in real time, with players taking turns to select moves and attack their opponents. The winner is the player who manages to defeat all of their opponent's Pokemon.
The game also features a ranking system, which allows players to track their progress and see how they stack up against other players. The more battles a player wins, the higher their rank will be.

Pokemon Showdown is a great way for Pokemon fans to test their skills and compete against other players. Whether you're a seasoned veteran or just starting out, there's plenty of fun to be had in this exciting online battle simulator.
