Scariest critters out there, non - daconic or infected Options

[fistandantilus4....]

Browsing through my Paranormal Animals of Europe here. Dreading the though of fighting some of them, thinking to myself "which one would make my players crap their pants the fastest".

Other than dracoforms and the infected, which critters have you had the hardest time against?

I ran a run where the whole team damn near got wasted by a Spectre in a basement. They got so desperate, they were literally calling other people on their phone for help. It was using telekineses to fire their weapons at each other, tied one runner up in barbed wire. one of them sat cringing in a corner for a while. They all crawled out with serious or better wounds. It was only force 6.

I'm also going to setup a run where the players have to extract an Abrams lobster rom a corp facility that it's a guard at and bring it back to Seattle for a banquet. It's the main course.

Then there was a fun adventure Mod (Predators and Prey I think) that was all critter runs.The massive battle that ensued running through the zoo of released paracritters was the best! Had a troll throwing down with a pair of wild minotaurs! Good times, good times.

Any other favorites? Anyone have a runin with a black berry cat?
