I'm trying to make a more comprehensive list of the institute's monsters, as well as any habits, common feeding grounds, and weaknesses that have been noticed. The first copy of this list was posted over a week ago. If anyone has corrections, sketches, or anything else to add, please do so. I'll post an updated version of this list each day.
Humanoid
A monster with the ability to look like someone close to you. Strong jaws.
A big, red, humanoid monster. Two heads and no eyes. Uses fire. Some say its poison paralyzes. [different handwriting] Fido [different handwriting]Flesh-eater. Will also eat anything thrown at its heads, including sharp objects. [Original handwriting] Aim for red spots
A woman with long hair. Fast, strong, and quiet. Is unaffected by injury. Bites and seems interested only in blood.
A woman with curly purple hair. Laughs and convulses. Mentions a master and carries a hot fire poker.
A woman with poison gas and and a big guy with chains on his wrists. If the woman dies, the giant loses its direction.
Two women: one whose skin absorbs nearby itsems and uses them as weapons, and another covered with needles and with scalpel fingers.
A child wearing a mask. Asks for his mother. His touch causes injury.
Three golden monsters with metal for skin and knives for fingers. Their weak point is at the base of the spine. Their blood has healing powers, but loses potency quickly.
