What is PewDiePie's real name?

PewDiePie’s real name is Felix Kjellberg, whose full birth name is Felix Arvid Ulf Kjellberg.

Kjellberg was born in Gothenburg, Sweden, on October 24, 1989. He created the PewDiePie YouTube channel in 2010 and initially became known for “Let’s Play” videos featuring horror and action games. His energetic reactions, improvised commentary, and distinctive audience community helped make him one of YouTube’s most recognizable creators.

The name “PewDiePie” came from “Pew,” a sound associated with laser fire, and “Die”; after forgetting access to an earlier channel called Pewdie, Kjellberg added “Pie” when creating the replacement account. The resulting name became his public identity, so many viewers know the alias more readily than his surname.

The wrong options are other major creators: Olajide “KSI” Olatunji, Sean “Jacksepticeye” McLoughlin, and Mark “Markiplier” Fischbach. They are separate YouTube personalities, not alternate names for Kjellberg.
