Slid down the clouds

"Moving forward ceased to be a pleasant option as it slid down evenly from the clouds overhead. Didn't matter, everything behind us was long gone by now. We prepared to charge"

- Trevor Henderson

Appearance
All that can be seen is thirteen spider-like legs in the mist. It looks to be hundreds or even thousands of feet tall. As said by Trevor Henderson himself, the creature, or its legs, slide down from the clouds.

Trivia

 * Instead of only having 8 legs like an normal spider has, it has thirteen.
 * It has also spiky legs, which could possibly be related to crabs.
 * it is unknown if this creature appeared in part 1 or 2 of the giants invasion
