Robbie Rotten is the main antagonist of LazyTown.
Every hero needs a good villain, and Sportacus has a doozy in Robbie Rotten. Robbie (or Mr. Rotten to you) can't believe that Sportacus is considered cool by the LazyTown kids, especially since Sportacus is a horrible example of what it takes to be a LazyTowner! The only thing that can tear Robbie away from snacking and TV in his underground lair is a new, nasty scheme to embarrass his sworn nemesis, Sportacus!
His most passionate desire is to burst Sportacus's balloon, both figuratively and literally. A master of disguises (well, at least he can fool our hero), Mr. Rotten is constantly luring our guileless hero into another nefarious trap designed to make Sportacus the laughingstock of LazyTown. But, somehow, Robbie's "brilliant" plans always fail, thanks to Sportacus's amazing athletic abilities and quick mind — plus the help of those darn kids! — LazyTown.com
Robbie has fair skin, green-grey eyes, and black hair. He usually wears a two-piece suit of maroon and purple with gold pinstripes, formal shoes, a navy blue shirt with cuffs and cuff links. He is the tallest character.
Robbie appears in every episode of LazyTown. His debut was in "Welcome to LazyTown" and his last appearance was in "Mystery of the Pyramid". He also appears in the following LazyTown productions that are not part of the series:
