Sportacus is the deuteragonist of LazyTown.
Sportacus 10 ('Sportacus' to his friends) is LazyTown's resident action-health hero. He's the hero every little boy and girl wants to be: fit, agile and an amazing acrobat with lightning fast moves. He loves to use everyday items in outrageous ways and never does anything ordinary when he can do it with flair. Patient and kind and always understanding, he doesn't tell the kids of LazyTown not to do something, but rather leads by example.
His kryptonite is sugar. Just the slightest bit makes him instantly lethargic, and he crumples to the ground in a heap. His primary mode of transportation is his large airship that hovers over LazyTown. He travels between airship and LazyTown in a pod-like transporter, the Skutla. Alerted to trouble by a large crystal on his uniform, he's ready in a flash to save the day.
Sportacus loves to see others succeed and is disappointed when they won't even try. He looks beyond the status quo and believes there's always a new, unique way to accomplish something. He's a hero-for-all seasons, bringing vim and vigor to a world that's sorely in need of it, an unstoppable wakeup force in a town that's fast asleep. — LazyTown.com
