Promethean Slayer is an advanced Forerunner AI that appears as a very difficult target in the Promethean Empire and in the Promethean Order . These Prometheans are shared as "Killers" due to with the same DNA of a human and can kill targets easily without no one noticing it and are mostly seen during the Human-Forerunner war

Three Leaders command the Slayers and are servants or leaders of the Slayers, Kronous, Vulkros and Durthros who all also are servants and leaders of the Ur-Didact, Jul 'Mdama and the Promethean Order.

Traits and WeaponsEdit

They can be armed with every Promethean weapon but are most commonly seen using the Light Rifle, Scattershot or Suppressor. They have a blade arm like most Prometheans, but only uses it when used for assassinations or beat down melee attacks, similar to the Sangheili's Energy dagger when used for most assassinations. While using weaponry, they are really well with it since if they equip a Binary Rifle, they can take down a Spartan in seconds and does really well with Assassinations which can either snap their opponent's neck or they use their blade arms to finish them off for good.

When in defense, they have a Hardlight Shield for blocking melee or projectile attacks, but also uses an Invicibility mode which makes it invurnable to most attacks for a minute which is the same invincible mode that a Jiralhanae Chieftain's uses when taking damage, but shows it as a orange version rather than a green/white version and also has more health for the mode unlike a Jiralhanae Chieftain's which has less health for the mode. Like the Brute Chieftain's, the invincible mode is only active if the Slayer is taking damage from it's target.

With the human DNA mixed into the slayer's blood, they became vicious, deadly and murderous Promethean types and during battles, they come with a squad of 6 or 8 and is a smart-type of Promethean during combat in battle.
