"Rule 34" is an Internet meme that states that if anything exists, whether in the real world or the virtual world, there is a pornographic representation of it. Gardevoir, a character that appears in the Pokemon games, is no exception to this rule.
There are numerous custom-made pictures that depict Gardevoir in scenarios that might be considered not safe for work. Since its invention, Rule 34 has been used to create many "childhood ruining" memes. In The Telegraph's article “Internet Rules and Laws: The Top 10, From Godwin to Poe,” this rule has been identified as one of the most popular, especially in the fan fiction community.
