Pokémon Showdown

Pokémon Showdown, also often formatted as Pokémon Showdown!, is a web-based Pokémon battle simulator. It is written in and , with its server infrastructure designed to run on . It was adopted by Smogon on July 2, 2012, and is open source.
In addition to standard modes of play, Pokémon Showdown! includes unique features such as "Pure Hackmons" and "Balanced Hackmons," which encompass Pokémon of normally illegal movesets and Abilities, and "Random Battles", which randomises both player's teams, balancing based on tiers. Some people also have custom servers in which they can create their own rulesets, battle formats, and even "Pet Mods" where they can change the entire way the game is played. The most notable of these side servers would be Dragon Heaven, which hosts modifications of this nature for Smogon's Pet Mods forum.
==Features==
Pokémon Showdown has move animations in battle. It supports replay sharing with one click and reconnecting to disconnected battles.
Pokémon Showdown supports Single and Double Battles in generation V through generation IX and also has support for Single Battles in all other generations. They also have Triple Battles though it is only in beta phase as with Multi Battles and Battle Royals. There are also custom battle styles, such as the Almost Any Ability or Monotype ruleset.
This website also features alternative servers which people can join through the main website. Examples include Sports, Dragon Heaven, and Pokémon Insurgence.

Pokémon Showdown has pioneered a de facto standard for Pokémon team notation.pokemon-showdown/TEAMS.md at master • smogon/pokemon-showdown

This consists of three sections:
# Declaration
#* Species name and 
#* Nickname
#* Gender
#* Held item
# Attributes
#* Ability
#* Level
#* Happiness
#* EVs, IVs, and nature
#* 
#* Dynamax Level, Gigantamax Factor, Tera Type
# Moves
In syntax definitions below, <...> just denote a named field. [ ] denote an optional field. { } indicates a field that may appear 0 or more times. Quoting indicates literals.
===== Declaration =====
This section has one of the two following syntaxes:
<nickname> "(" <species-name> ")" ["(" <m-or-f> ")"] ["@" <item>]
<species-name> ["(" <m-or-f> ")"] ["@" <item>]
The nickname field is optional. If it exists, the species name must be surrounded by parentheses.
The <m-or-f> field just indicates that there should be either the letter F or M, which indicate female and male, respectively. Gender unknown Pokémon do not have this field.
The item field is optional. If the Pokémon is holding an item, the item's name must be preceded by an at sign. Example: @ Leftovers.
===== Attributes =====
Each attribute in this section is formatted like this:
<name> ":" <value>
 Data types
Type 	Description
Integer 	Whole number
Boolean 	"Yes" or "No"
Stat list 	List of <number> <stat> pairs, separated with slashes (/).
Stat names (except HP) are translated:
* Atk -> 
* Def -> 
* Spe -> 
* SpA -> 
* SpD ->
Entity name	Self-explanatory
These data types apply to the fields:
 Fields
Name 	Type 	Description 	Default value (if optional)
Level 	Integer 	Between 1 and 100 	100 (50 for World Championships formats)
Happiness 	Integer 	Between 0 and 255. This is only used to determine the base power of and . 	255
Dynamax Level	Integer 	Between 0 and 10. Indicates by how much a Pokémon's HP will increase when it is Dynamaxed.	10
Ability 	Ability name	The Pokémon's Ability 	The species' first Ability
Nature 	Nature name 	The Pokémon's nature. Formatted as <name> Nature 	Serious
Tera Type 	Type name 	The Pokémon's Tera Type 	The species' primary type

Gigantamax 	Boolean 	Gigantamax Factor presence 	No
EVs 	Stat list 	Effort values 	Missing stats: 0 EVs
IVs 	Stat list 	Individual values 	Missing stats: 31 IVs
===== Moves =====
This section contains up to four entries formatted like this:
"-" <move> [ "[" <type> "]" ] { "/" <move> [ "[" <type> "]" ] }
The <type> field is only for moves that can have variable types that can be applied or seen outside of battle, e.g. or .
More than one move can be specified for each slot, but the moves after the first slash are usually ignored.
==== Packed format ====
The packed format consists of entries delimited with ], where fields are delimited with |, and data in fields is delimited with ,.
There is no ] after the last entry. Skipped fields don't have any content. An example team in this format looks like this:
Articuno||leftovers|pressure|icebeam,hurricane,substitute,roost|Modest|252,,,252,4,||,,,30,30,|||]Ludicolo||lifeorb|swiftswim|surf,gigadrain,icebeam,raindance|Modest|4,,,252,,252|||||]Volbeat||damprock|prankster|tailglow,batonpass,encore,raindance|Bold|248,,252,,8,|M||||]Seismitoad||lifeorb|swiftswim|hydropump,earthpower,stealthrock,raindance|Modest|,,,252,4,252|||||]Alomomola||damprock|regenerator|wish,protect,toxic,raindance|Bold|252,,252,,4,|||||]Armaldo||leftovers|swiftswim|xscissor,stoneedge,aquatail,rapidspin|Adamant|128,252,4,,,124|||||
Normally, no line breaks are used, but are sometimes included for readability:
Articuno||leftovers|pressure|icebeam,hurricane,substitute,roost|Modest|252,,,252,4,||,,,30,30,|||]
Ludicolo||lifeorb|swiftswim|surf,gigadrain,icebeam,raindance|Modest|4,,,252,,252|||||]

thumb|200px|April Fools sprite change of and 
On April Fools, all the sprites of the Pokémon are replaced with alternate sprites. The sprites usually poke fun at the Pokémon's appearance, commonly comparing them to objects they resemble or characters from other popular culture. The commands "/afd on" and "/afd off" can enable and disable the April Fools sprites respectively. Attack animations occasionally end with a hitmarker.
The April Fools sprites were first used on April Fools' 2013. They have been frequently updated so that sprites for subsequent generations are included in the April Fools' days.
===Halloween===
On Halloween, some moves receive a different animation, particularly -type moves such as .
