Hatterene became a breakout meme star following its debut in Pokémon Sword and Shield, primarily due to its unsettling Pokédex entries that describe its intense hatred for strong emotions and noise. Fans quickly dubbed it the 'Vibe Check' Pokémon, creating memes where Hatterene uses its massive claw-like hair to punish anyone displaying too much excitement. Its contrast between a delicate, feminine aesthetic and a brutal, 'silent but deadly' personality resonates with internet users who value their personal space or relate to being easily overstimulated. Today, the template is widely used to humorously shut down loud opinions or dramatic outbursts across social media.
