The local hero of LazyTown, who modestly calls himself only a "slightly-above-average" hero. He, presumably, comes from an island in the North Sea like his predecessor, who has been only identified as "Number 9" in the series. He is highly athletic, as shown by his name, and does flips and jumps to do simple things such as brushing his teeth or preparing himself a sandwich. His only weaknesses are: not knowing how or when to relax and sugar, with the second causing him to suffer an exaggerated sugar crash, which he calls a Sugar Meltdown.
Sportacus is a very understanding and modest person. He knows what he is capable of and is always worried for everyone. He's always trying to help people when he feels it's needed. He doesn't hate anyone (including Robbie Rotten) and he wants to be friends with everyone (even Robbie!). He always sticks with the kids when they are playing or doing sports and he knows what they are capable of. He trusts them a lot, enough to give them responsibilities, knowing they are going to do them. He's not perfect, and has been saved by the kids on several occasions, but he never gives up and he always does his job
