Character: The leader of a Shark Invasion, tired of human pollution they have decided to end the world with the help of their sweet robotics.

Voice: Heavily distorted, they speak through a translator box. Medium pitch, should sound robotic or automated. Can be either in a typical Translation-Software style robotic or a customer facing phone-line recording. I think multiple approaches are valid and will have different readings. An unexpressive plain reading via translator box would work, as would an incredibly cheerful female customer support rep for contrast. Have fun with this one.
