Pokémon Showdown, also often formatted as Pokémon Showdown!, is a popular Pokémon battle simulator, currently peaking close to 4,000 users as its stats show. As of July 2, 2012, it was adopted by Smogon and became one of the first battle simulators to support the changes brought about by Black 2 and White 2. In addition to standard modes of play, Pokémon Showdown! includes unique features such as the emerging tiers "Hackmons" and "Balanced Hackmons", which encompass Pokémon of normally illegal movesets and abilities and are not supported by any other popular simulator.
Pokémon Showdown was the first simulator to support animated battles. It is currently the only simulator that supports one-click replay sharing, and reconnecting to disconnected battles. Pokémon Showdown supports single and double battles in Generation V, and also has support for Generations I and IV, with upcoming support for II and III.
Pokémon Showdown was created by Zarel, and the current development team includes Cathy and bmelts. The project is open-source and has many other development and graphical contributors as well.
