In the game “Fortnite” there are currently two NPC bosses. One in the location Mega City, the other in the Landmark, Shattered Slabs. In Mega City, the NPC boss “Highcard Havoc” has loot of the gun  Havoc Suppressed Assault Rifle, the rarity is Mythical. The NPC boss also has loot of a Vault Keycard item, which can unlock a small domain called a vault. The NPC boss also has two NPC guards that are neutral: They only attack if fired upon. The NPC guard has a 100% chance of having loot of a Rare Twin Mag SMG, and a 20 small ammo. In the Landmark Shattered Slabs. The process is the exact same, but the vault is in a different location. One vault keycard cannot open both of the vaults. This boss spawns after two minutes in the game, which is one full storm circle.
