Robbie Rotten

Robbie Rotten is a fictional character from the children's television show LazyTown. As the antagonist of the series, he tries to get the other characters to eat junk food and is forever trying to banish Sportacus from LazyTown. He wants to make sure LazyTown stays lazy, as it was before Sportacus came to the rescue. He is known to be a master of disguise.

Robbie creates all sorts of plans to promote physical inactivity in LazyTown, and sometimes comes very close to succeeding, but Sportacus always manages to save the day with the help of Stephanie and her friends. The amount of effort that this champion of inactivity puts into his plots is ironically huge; he could easily be considered one of the most active people in LazyTown. In the television show, Robbie Rotten is played by Stefán Karl Stefánsson.
