Rango is the titular main protagonist of Rango. He is a intelligent and eccentric chameleon who is initially a pet of a human family but afterwards a incident with the car he falls out of his box and the car having himself finally free and he arrives in the Western city called Dirt where he becomes the new scheriff and start to becoming a great hero.
Rango, whom was a family’s pet chameleon; after a car accident, he is then abandoned in the middle of a road in a desert. He then meets an injured armadillo, whom was caused by the accident, and guides Rango on how and where he should go to survive.
Although “Rango” is not his real name, he got the name idea from a beverage in the town of Dirt, which the townsfolk believe is his actual name.
Rango is a very comical character but also lonely as he remains isolated in his box and is actually seen conversing with inanimate objects such as a headless mannequin, a dead cockroach, a toy fish and a decorative tree; however he actually believes he has friends and a very active social life only to be corrected by Roadkill claiming him to be a very lonely lizard.
Throughout the film Rango was seen suffering from an identity crisis, he is constantly seen saying "who am I?" to himself and doesn't even know his own name causing him to create his own identity. Rango is an actor and expects his "friends" to be the same, he describes Victor, an inanimate tree as wooden and his toy pet fish Mister Tibbs, good - too good. After arriving at the town of Dirt, Rango was able to create his own identity and name, he also had a tendency to go over-the-top as he said where he came from they kill and cannibalise a man before breakfast just to wake up an appetite.
Rango was at first cowardly, such was shown during the desert and he caught the eye of a hawk and than away screaming in terror, this also happened again during a showdown with Bad Bill and his crew, the hawk returned which caused Rango to cower in a latrine and then flee. He was also in clear terror when Rattlesnake Jake entered Dirt however so was everyone else. He later became brave and fearless at the end of the film where he threatened to shoot Rattlesnake Jake with one bullet.
Despite his stories claiming that he was the one who killed the seven Jenkins brothers, Rango had never and was always reluctant to actually kill someone, this was shown when a hawk was close to eating him, and Rango aimed the gun at the hawk but then hesitated and shot the rope that was restraining one another which accidentally caused the hawk to be crushed but made the town believe that Rango was the one who killed it. This changed when he never became reluctant to kill Jake with one single bullet.
After the Mayor made Rango the Sheriff of Dirt, he was shown to be very clueless almost shooting a child in the face when he only wanted an autograph and then handing him a gun. He also came across three bank robbers and mistakes them for miners then actually gives them a prospecting permit then giving them directions to the Bank of Dirt.
Despite this Rango can also be intuitive and intelligent, when him and his posse captured Balthazar and his family, he was able to realise that something ominous was happening in Dirt and believed that they found the empty jug of water and didn't murder anybody. When the Spanish Daggers were seen walking like the legends told they do towards water and discovered Las Vegas where he realised that the Mayor's true plan was to buy up all the land and then bring back the water when Dirt was washed away.
After being humiliated by Rattlesnake Jake, Rango shamefully leaves Dirt but after a pep talk from the armadillo, and uncovering the Mayor's true plan; he returned to Dirt and showed true bravery and made an alliance with Balthazar's family, then confronted Jake. He became a well known legend and hero to the townsfolk of Dirt after returning the water.
Rango is shown to have green scaly skin (which change colours when he blends into his surroundings). He once wore a red Hawaiian shirt, until he wore Western clothing. His sheriff clothing is a white shirt with brown pants, dark brown waistcoat and his silver sheriff badge. He wears a yellow white hat, but later a brown hat when he returns to Dirt along with a brown blanket cape.
During their ambush with Balthazar and his gang, Rango wore Beans' gown while she wore Wounded Bird's blanket cape.

- Intelligence - Rango seems to have very high intelligence as he was able to capture Balthazar and his family (who were falsely accused of stealing the water cooler bottle). He is was able to think of a clever plan to retrieve Dirt's water and ally with Balthazar's family and men in an attempt to distract Rattlesnake Jake by using bats in the form of a Hawk. He is shown to use his intellect to defeat two of Balthazar's men when he pulled the wagon's brakes and the two bullets hit Balthazar's men instead of him and Beans.
