New Killer Concept (The Blood Harvester)

In a dark future, technology had increased to a point where humanity no longer needed other humans to govern themselves. They instead gave that task to machines, what humanity didnt know was that the machines had grown far beyond their control and in one swift move the balance of power shifted and humanity was now just fuel for their new overlords.
These machines, these Overlords needed a vessel to go out to collect their prey for them and decided to built a servant in their enemies image.

Introducing The Blood Harvester, a machine built to look like a human needing nothing but a fuel source, blood.

The Blood Harvester is Tall, Moves at 4.4 meters and has a 32 Meter Terror Radius.

Using his metal syringe stiched into arm he will never let his masters go hungry. His Power (Overlords Will) The Blood Harvester will take his syringe and jam it into a survivor draining them of blood, it will take 3 attacks using the syringe to fill it up to full. Once the syringe is full a new entity will emerge in the trial, a mechanized being holding out his hand expectingly to the Harvester. The Harvester can then empty his syringe to the Overlord and be granted a buff called Blessing From The Overlords. Once this buff is active The Harvester now moves at 4.6 meters, has increased vault speed, and any time he hits a survivor in this state all other survivors will become deafened for 25 seconds.

Survivor Counterplay: to prevent the Blood Harvester from getting Blessing From The Overlords Survivors can instead head to the Overlord and offer their blood to it and grant buffs for not only themselves but for the whole team. Once a survivor offers their blood the whole team gets a 5% haste for 20 seconds as well as be gifted a random item ranging from green to blue rarity.
