Toothless Teddie (often just going by "Teddie") is a British digital creator, YouTuber, and cosplayer who has built a dedicated following through her chaotic convention vlogs and high-quality character recreations. She frequently goes viral for her humorous short-form videos documenting her experiences at major pop-culture conventions (like MegaCon Live in the UK and Katsucon in the US) and her rapid-fire cosplay builds. Her content leans heavily into internet culture, gaming, and anime, frequently featuring group cosplays from games like Dandy's World (Roblox) and franchises like My Little Pony and Sanrio.
