Dr. Octavius Brine (John Malkovich) - Penguins of Madagascar
Meet Dr. Octavius Brine: an eccentric genius and successful scientist – or is he? Beneath his human masquerade lies "Dave," an octopus with a haunted past and a grudge against penguins.
These octopuses do "Dave’s" bidding with ninja-like moves. Their innate ability for camouflage, flexibility, and a viselike grip make them a multi-limbed threat to our heroes.
