Allister is the hauntingly quiet Ghost-type Gym Leader of Stow-on-Side, first appearing in Pokémon Sword and Shield. Known for rarely taking off his mask and his immense social anxiety, he quickly became a fan-favorite for both his design and his shy personality. In the meme world, Allister is frequently used to represent introversion, social awkwardness, or spooky energy. The memes often play on his eerie appearance contrasted with his young age and timid nature, making him a relatable figure for anyone who feels a bit out of place in social settings. Whether he is peeking from behind a wall or standing silently, Allister serves as the perfect visual for those moments when you just want to disappear into your own shell.
