Large and bulky, Knifehead is a heavily built Kaiju. Its most notable feature is the long and broad sharp-ended nose, that could easily cut through the armor of a Jaeger. Atop the center of its head resides a blowhole that forcefully expels air whenever it resurfaces from the water. It has a large shell-like armor on its back, while the rest of its body is similar to a goblin shark in appearance.
