I remember seeing this on tv late one night, it would have been the late 80s it was a monster movie set in a city. One scene that sticks out was a woman being chases down a alleyway by some creature which looked like it had many faces or bodies melted together. The woman then runs into a woman sat on a wall she is dressed as a biker and is told to run but she stays and you see the creature slowly approach and attack. It’s very vague but the one scene that I remember well would love to find and watch again
