Rolf

Rolf is an immigrant from a curious and possibly fictional culture known to us only as The Old Country. The most evidence was shown in the episode "No Speak Da Ed." There it was revealed that he is familiar with a trickster named Gerta, and Gerta lives in Norway. During flashbacks in that episode he is seen being chased by what appears to be someone in a wolf costume. Rolf works on his parents' small farm within the Cul-de-Sac and leads a scouting group called the Urban Rangers, a Boy Scout-like group which includes Jimmy, Plank, and Jonny. Rolf often refers to himself in third person, as well as being the son of a shepherd, in which he takes great pride. He hardly minds the Eds unless they make a fool out of him or insult his culture, after which he is not afraid to use brute force. When his superhuman strength is unleashed, it rivals Ed's; however, it should be considered that he is the second strongest character in the show, since he is seen lifting a tree with difficulty while Ed can lift a house single handed. Rolf's strength depends on his mood rather than his biology, however.

Rolf confuses the rest of the kids with his unusual customs and food-making. He is one of the few characters who gets respect from all the kids. His best friend is Kevin and he relates well with Jonny, as he tends to be an outsider as well. Rolf has a very strong accent and is exceptionally hairy. Although he has not revealed his age, he claims that his hair is premature (as mentioned in "Scrambled Ed"). He has a strong liking for meat, and when he agreed to a bet to not eat meat for a whole day, he became extremely malnourished and had severely lost his muscle tone almost instantly, not even having enough strength to open the cafeteria door or bite through celery. Nobody except himself and his family knows what country he is from but, as every single thing that's linked to him is known, he is most likely from Northern or Eastern Europe; however, this country he comes from is apparently fictional. While Rolf does speak English, he also has a tendency to speak in third-person.
