Dave, A.K.A. Dr. Octavius Brine, is the primary antagonist of the 2014 film, Penguins of Madagascar. He was voiced by John Malkovich.
Dave the Octopus was once a global star attraction, an octopus of a thousand tricks. Unfortunately, the people adored the penguins more then Dave, which led to him being kicked out. Ever since, he wanted revenge on them, and he also disguised himself as a human scientist named Dr. Octavius Brine. He hired several octopuses as his henchmen, and created a mutating chemical liquid that he calls the Medusa Serum. With that, he would eventually get revenge on the penguins.
Penguins of MadagascarEdit
Dave captured every penguin from every zoo that he was kicked out of, including Skipper, Kowalski, Rico, and Private. Private escapes, but Dave is still turning the penguins into monsters. He then releases them on a rampage in New York City, and terrorizes the citizens in doing so. However, Private manages to turn all of his friends to his side, and they learn that they can use Private's cuteness as a reverse for the Medusa Serum. However, Dave and his henchmen attempt to stop them, but Private punches Dave with his butt hand, which he developed as a side effect from the serum, and knocks him away. The other penguins then use the machine to turn themselves and all of the others back to normal.
Later, it is revealed that Dave has also been caught in the blast, and as a result, he got shrunk and trapped in one of his snowglobes. He swears revenge against the penguins, but is interrupted by a little girl, who picks up the snowglobe and proceeds to shake it around, while Dave is inside.
It is unknown what happens after this, but it's likely that he reforms and becomes her pet.
- Dave is the only octopus in the film that can speak, and the others just make bubbling sounds. The reason for this is unknown.
- Following the penguins' despair, Dave also planned on taking vengeance on cats and dogs. It's possible that he was embarrassed by them, as well.
- Ironically, although Dave was the main antagonist in the feature film, Dr. Blowhole is the Penguins of Madagascar's real arch-enemy. This is probably because Dave reformed and most likely bacame an ally. This also points to the fact that the film takes place before The Penguins of Madagascar T.V. series.
