This 23-second clip features a deep villainous voice declaring 'I am the Eggman, that's what I am' over driving rock music. It feels swaggering, theatrical and gleefully over the top, like a cartoon villain announcing himself before a scheme. It is the villain's character theme from Sonic Adventure 2.
