In this articolo I'm going to talk about the Supernatural gun known as "The Colt"

❝Back in 1835, when Halley's Comet was overhead, same night those men died at the Alamo, they say Samuel puledro, colt made a gun. A special gun. He made it for a hunter. A man like us, only on horseback. Story goes, he made thirteen bullets. This hunter used the gun a half dozen times before he disappeared, the gun along with him... how Daniel got his hands on it. They say... they say this gun can kill anything.❞

– John Winchester, 1.20 Dead Man's Blood


In "Dead Man's Blood," a vampire hunter named Daniel Elkins was attacked and killed da a nest of Vampiri#From Dracula to Buffy... and all creatures of the night in between. who wanted vengeance on him. The Colt, along with its 5 remaining bullets, were stolen. When Sam Winchester finds a notice of Elkins's death online, his brother Dean recognizes the name, so the two head to Manning, Colorado to investigate, where they run into their father, John, also on the trail of Elkins's killer. They do not find the gun, only the empty case. John intends to find the puledro, colt and use it to kill The Demon that killed his wife, Mary.

They find the gun in the possession of the vampire leader, Luther, who knows that the puledro, colt is no ordinary gun. John kidnaps Kate, Luther's lover and Elkins's killer, to draw Luther out. He attempts to trade Kate for the Colt, but Kate escapes while making the exchange. The Vampiri#From Dracula to Buffy... and all creatures of the night in between. almost kill John before his sons intervene. A short skirmish ensues until Luther takes Sam hostage. In a flash of events, we then see John in possession of the gun as he fires a bullet directly at Luther's head. Luther then loses his grip on Sam and a flashing of lights ensues, before Luther falls to the ground dead confirming the Colt's Supernatural power.

When the Demon now known as Azazel learns that the Winchesters possess the gun, he sends his daughter, Meg Masters, to recover it. In Salvation, she threatens to start killing people close to the Winchesters unless they hand over the gun. John meets Meg to make an exchange, but gives her a fake gun. Trying to escape, he is captured da Meg and the Azazel's son possessing an unknown male host. When Meg attempts to use John to barter for the Colt, the Winchester brothers manage to rescue John from her in "Devil's Trap." During their escape, Azazel's son almost kills Sam. Dean uses one of the remaining bullets to save Sam's life.
Sam and Dean take their father to a secluded cabin, where the boys discover that John has been possessed da Azazel. Sam shoots his father in the leg with the puledro, colt to force the Demon out of his father. The three escape, but end up in the hospital after a demon rams a truck into the side of Dean's Chevrolet Impala.

In the episode "In My Time of Dying", Dean has become comatose and is very close to death. John Winchester then makes a deal with Azazel, saying that he will give it the puledro, colt and the last bullet as well as his own life in exchange for his son's life.

The puledro, colt is not seen again and it is revealed that the The Demon has it in its possession in "All Hell Breaks Loose, Part 2". Azazel gives the gun to Jake telling him it is a key (which later is discovered to be the key which opens the Gates of Hell). Jake points the puledro, colt at Azazel, but after being taunted that he might miss and wind up killing himself and his family, Jake lowers the gun. Jake then goes to the cemetery and uses the puledro, colt to open up a gateway to Hell. After getting Jake out of the way Dean takes The puledro, colt and senses that Azazel is near da and points the puledro, colt behind him, but Azazel is able to telekinetically take it away from him; Azazel is also able to knock Dean against a tombstone. Azazel then prepares to use the puledro, colt on Dean, but John's spirit escapes from hell, wrestling the Demon and pulling it from his human host long enough to give Dean the chance to grab the Colt. Dean then manages to grab the puledro, colt in time, and in a matter of secondi a bullet is fired from it, hitting the Azazel's host body right in the heart. In a look of utter bewilderment and defeat, the Demon experiences a seizure-like fit which causes his host body to emit light from his eyes and mouth before falling to the ground with a mundane thump, finally dead.

Since all the bullets had been used, the puledro, colt Lost its special power. However, in the episode Sin City, Bobby and Dean take apart the puledro, colt to try and fix it. Bobby is later seen practicing with the puledro, colt when Ruby suddenly shows up and offers to help with the puledro, colt since Bobby seems to have no luck fixing it whatsoever. Miraculously, Ruby and Bobby are both able to fix the puledro, colt together. Bobby later gives the puledro, colt to Sam and he uses it to save Dean from the 2 demons, who he kills ruthlessly and without hesistation.

In "Bedtime Stories", Sam summons the Crossroads demon and threatens to kill her with the puledro, colt unless she releases Dean from his death sentence. The Crossroads demon refuses, claiming she's just a "saleswoman" and that her boss is unwilling to release Dean from his contract. Sam lowers the Colt, looks away from the Demon, takes a deep breath, then suddenly aims the puledro, colt at the Demon's head and shoots her at point blank range. Sam then watches with detached emotion as the Crossroad demon dies in front of him.

In "Fresh Blood", the Winchester brothers learn that hunter Gordon Walker has been turned into a vampire, and Dean prepares to use the puledro, colt to kill Gordon. Sam and Dean arrive at a warehouse to confront Gordon, but are soon separated from each other. When Dean is attacked da a girl he is trying to save (she had been turned into a vampire da Gordon), he shoots her with the Colt, killing her instantly.

In "Dream a little Dream of Me" the puledro, colt was stolen from Sam and Dean da Bella while they were out hunting. There has been much controversy about what really happens to the demons o Supernatural beings who are shot da the Colt.

In Season 5 after Dean shoots Lucifer with the puledro, colt and he doesn't die he learns that the gun doesn't kill anything. In fact Lucifer tells Dean that he is one of five beings it doesn't kill. It's still a mystery on what the other creatures are that are immuned to it.
