You do realize what the Colt is right? It's an instant plot device kill weapon that overrides immortality, immunity, invulnerability, and unkillability. Comparing the Colt to any other gun is WAY, WAY off. It just doesn't compare whatsoever. There is absolutely no comparison. The fight was stated to be a one on one. Not army vs army. That is the apocalypse. The other opposing teams of angels have their own squabble. But the main event is Mike vs. Lucy. Which would roast most of the planet during the battle as a side effect. The fact that Lucifer displayed more powers shows that Michael is stronger because they are both archangels and he(Michael) is older. No Leviathan has done what lucifer has accomplished - killing pagan gods, taking a shot from the colt, possessing the durability to take shots that can decimate most of the planet. Which is why I doubt they can be decapitated because power correlates with durability. The Leviathans have far lower durability as already proven.
