Picafi

He is made of a ghostly mist and can make clones of himself from it, although his clones aren't physical beings. He and his clones are able to phase through walls and other things. He is in the first and second floors of the lab building. He can send his hands as separate entities to hunt targets down easier. He can send his mist through the lab's vents in an attempt to grab you. Also, his clones always have their hand with them, and are just distractions, not actually able to hurt you.
