Rattlesnake Jake

Rattlesnake Jake is the anti hero and main antagonist in the 2011 Nickelodeon film, Rango.

Appearance
Rattlesnake Jake is a dangerous western diamondback rattlesnake wearing a cowboy hat and with a Gatling gun in place of his rattle on the tip of his tail.

Rango
Early in the film, Rango claims that Rattlesnake Jake is his brother when he is first brought up by the townspeople while making up his overblown heroic persona; thus, when Jake attacks the town, he uses this bold-faced lie to expose Rango as a phony in front of everyone and drive him out of town. It is then revealed that Jake is working for the evil Mayor Tortoise John and, in a later scene, he is seen forcing Beans to sign away the deed of her father's ranch to the mayor and almost strangles her to death before Rango shows up again outside. With the help from the hill clan, Rango defeats Rattlesnake Jake and is about to shoot him, but the Mayor threatens Beans' life, forcing Rango to surrender to the Mayor.

During the final confrontation, the Mayor betrays Rattlesnake Jake by pointing Rango's gun on him, declaring him another relic of the Old West that will soon be destroyed and forgotten along with the rest of the town. When the Mayor tries to shoot, it turns out that the last bullet was taken by Rango, who then uses it to break open the giant water bottle he and Beans were drowning in and flush everyone out of the town hall into the streets, where Rango finally manages to subdue the Mayor. Rango then turns the defeated Mayor to Rattlesnake Jake, who then nods his hat to Rango for saving his life, acknowledging him as another great desert legend that will thrive. Having developed a new found respect for Rango, Rattlesnake Jake returns the Mayor's favor by telling him the exact same thing the Mayor said to him, that soon no one will even remember his existence and snatches the Mayor up in his tail and carries him out into the desert to kill him for his betrayal, thus taking a soul, as Bad Bill said.
