Giant Mantis

The Giant Mantis is a daikaiju-sized insect which attacked Paris. This monster was created by Dina Cimarusti for the Face Off season 7 "Creature Carnage" challenge. The judges praised this creature and chose it as the episode's winner.

Backstory
According to Dina, this is a female preying mantis who really enjoyed devouring the heads of her mates (as mantises typically do) and ate tons of them. She then "worked her way up the food chain to the big city, where there are thousands of men for her to feast on".
