Charles F. Muntz

Charles F. Muntz is the main antagonist in the film Up. He was a famous, greedy, paranoid explorer, who was an adventurer that Carl and Ellie admired when they were kids.

Up
Charles departed for South America after scientists claimed that Charles had faked his discovery of the skeleton of a 13-foot tall tropical bird, vowing to find a living specimen. Unfortunately, the countless years that Charles spent there had made him greedy and paranoid, believing that anyone who came to Paradise Falls was after the bird to steal his glory.

Charles is an avid dog lover and inventor, being able to train them to do practically anything, and has invented devices that translate their thoughts into speech. He is the master of many dogs, including Dug (who is now Carl's pet, and Carl is now Dug's master), Alpha, Beta, and Gamma.

It is revealed that Charles has become quite ruthless in order to obtain the bird; he goes as far as to attempt at killing Russell, among other things. Presumably, he dies after having been knocked off of his blimp, the Spirit of Adventure (with Carl's old house).
