Every made up creature in my stories (not counting Fallen World) part 1:

Ferociraptor (definitely the most iconic as it was the first one)

Acidosaur (easily forgettable, probably only remembered for one groups very violent death)

Sevrawing (I honestly forgot about this one, two appear in the last few chapters of Apex Predator and they have virtually no role in the story)

Savagaboa (big snake from The Jaws of Death, probably one of my least liked and easily forgotten stories)

Ferocisaurus Rex (big, powerful and scary, appeared in The Jaws of Death and Clash of the bio Titans, two of my least liked stories)

Horror wolf (giant wolf that appears in The Jaws of Death)

Horror bear (giant bear that appears in The Jaws of Death)

The Mountain King (huge mammoth monster from The Jaws of Death, easily forgettable)

The four Bio Titans (biggest, strongest and meanest of my made up creatures, appears in one story and one can only be killed by another Bio Titan)
