[1] Åberg has produced some of the most successful films in Sweden,[citation needed] depicting "typical" Swedish life and customs in a usually humorous way.

[citation needed] Åberg's character can be described as an inept outsider with a large heart, constantly pushed aside without noticing.

As an artist, he is famous for making various lithographs, with one of his specialties being sketchy Mickey Mouse pastiches.

Åberg is also the creator of Trazan & Banarne, one of the most beloved Swedish children's shows ever.

The characters of the show, Trazan Apansson (Åberg) and Banarne (Klasse Möllberg) are also members of the Electric Banana Band.
