Kludd is one of the two secondary antagonists (alongside Nyra) of Legend of the Guardians: The Owls of Ga'Hoole. He is an adolescent barn owl, the first son and eldest child of Noctus and Marella and the elder brother of Soren and Eglantine who joined forces with the Pure Ones out of vengeful spite against Soren.
Unlike the books, in which he goes by the title of Metal Beak and leads the Pure Ones, Kludd and Metal Beak are two different owls, with Metal Beak being a sooty owl named Surtr (as revealed in the film's video game). Kludd's personality is also not as dark as his book counterpart due to his better relationships with his siblings up until his betrayal. Also in the film, Kludd does not push Soren from the nest, resulting in the latter's capture, as he hadn't been in league with the Pure Ones at this time and instead is captured along with Soren and taken to St. Aegolius.
