April 1, 2013 was an April Fools' Day that fell on a Monday. In the Pokémon fandom, some websites pulled hoaxes on gullible fans.
Other fan sites
- Psypoke featured a Slowpoke crawling across the bottom of the site and forums with the message "HAPPY NEW YEAR!" on April 2, 2013 after not running a prank on April 1.
- PokéCommunity made all of their user's posts have a random Pokémon for their avatar, username and the custom user title to that of the random Pokémon. The Pokémon would change upon every time the page is refreshed, and the Pokémon may become a Shiny Pokémon, signified by a sparkling effect on the username and the avatar would show a Pokémon's shiny sprite. Also, the fifth generation gaming moderator "Forever" claimed that she would be leaving the site, but was later revealed to be a joke.
- Pokémon Database changed the header to use "Disapprovalmon", turned all images upside-down, and changed to font to Comic Sans.
- Project Pokémon changed the forum name to Project Digimon.
- PKMNcast.com, which normally features a Pokémon of the Week on Mondays, instead featured an article about Cardfight!! Vanguard.
- Smogon and Pokémon Showdown! changed all the sprites on Pokémon Showdown to various fan-drawn sprites.
- The official Pokémon Facebook account posted news that revealed several colleges would be offering courses in Pokémon mastery.
