Pieter Krämer is the secondary antagonist in the 2015 sequel, Pitch Perfect 2.
He is portrayed by Flula Borg.
Pieter is the co-leader of Das Sound Machine, a German a capella group (he shares that role with Kommissar). He and the rest of the group accost the Bellas at a car show and taunt them condescendingly. A short time after, they do the same thing at the Riff-Off. The Bellas and Das Sound Machine make it to the final round, but DSM wins when Emily bombs her song. At the World A Capella Competition, the Bellas and DSM compete once more, but thanks to a surprise appearance from former Bellas Aubrey and Katherine, the Bellas win. Pieter and Kommissar shake their heads and walk away.
