Robbie Rotten is the lazy, scheming antagonist of LazyTown, the Icelandic children's series that first aired in 2004, played by Stefan Karl Stefansson. His flamboyant musical numbers outlived the show online, especially after his villain performances were remixed, quoted and used as reaction clips across meme culture in the mid 2010s. Fans remember him less as a scary bad guy and more as a theatrical scene stealer, which is why even a very short burst of his villain music still signals a comic plot, a disguise, or a proudly overblown evil plan.
