Tortoise John

Tortoise John is the main villain of the 2011 film Rango. He is the wheelchair-bound turtle mayor of the town of "Dirt", where there is a major water shortage. From the start, he is made out to be very untrustworthy, greedy and corrupt, such as keeping a large personal supply of water for himself. When he first appears, he appoints Rango as the new sheriff and mentions that "whoever controls the water controls everything." Later in the film, it is revealed that he is building a modern city over the desert surrounding Dirt, and subsequently that he has been intentionally cutting off the town's water supply, which is actually connected to Las Vegas, and making the people believe that there is actually a drought, intending to let the town die out to make way for his new plans.

He murders the town bank-keeper, Merrimack, and when Rango starts to deduce his schemes he hires Rattlesnake Jake to drive Rango out of town, but Rango comes back to stop them after fully discovering the Mayor's plan. However he captures Rango and Beans and starts to drown them in the town's water supply bottle. He then turns a gun on Rattlesnake Jake, telling him that he too is part of the obsolete Western era that he intends to destroy, but when he pulls the trigger he finds that the last bullet was taken by Rango, who uses it to break open the water bottle, flooding the town hall and sending them all outside, where an infuriated Rattlesnake Jake paraphrases the mayor's previous words to him, that "no one will even believe you existed", and carries him into the desert to kill him.

The Mayor was voiced by Ned Beatty, who also played Lots-o'-Huggin' Bear. The two characters are actually very similar, but the fact that they are both played by the very same person makes this truly noteworthy.
