Mats Mikael "Micke" Dubois (25 February 1959 – 30 November 2005), also known as Svullo, was a Swedish actor and comedian.

In 1988 he got the idea for the character Svullo, a Swedish taunt name for obese people which is derived from his big body mass.

At the time, bodybuilding was very popular and Dubois trained at the same gym as Arnold Schwarzenegger, gaining a lot of muscles.

During the early 1990s, Dubois created a journalist character named Skägget (The Beard) who wore a fake goatee and made a series of home interviews named Hemma Hos (At Home) with Swedish celebrities, including Claes "Clabbe" af Geijerstam, Anna Lindh and Alice Timander.

In the late 1990s, Dubois starred in some TV productions, for example "Knäppa Klipp" (Crazy Clips) and "Robot Wars".

He also directed a theatre play called "Hur man lyckas i showbusiness utan att bli utbränd" (How to succeed in show business without getting burned out).

It contained some Angne och Svullo sketches, bloopers and outtakes from Knäppa Klipp and a special tribute with celebrities including Ulf Malmros (who directed Den Elake Polisen), Markoolio and Sven Melander who all talked about the energy and charisma of Dubois.
