Supernatural's Colt is a special gun that can kill virtually anything. 1 / 7

Apart from Lucifer and 4 others. Most likely including God, Darkness and Death. 2 / 7

The Colt was left in the past in season 6, written out for being too powerful. 3 / 7

But it returned in season 12, only to be melted into two by Dagon. 4 / 7

Once again, it had become too powerful after Bobby found a way to make the bullets. 5 / 7

Like anything else, the Colt can still return in Supernatural. 6 / 7

But it'll likely be useless against Supernatural's apparent final villain. 7 / 7
