User blog comment:AustinDR/My Favorite Cryptids/@comment-2059440-20180923204906

many theorize that Greys are also wearing bio-suits, hence their strange uniformed appearance - prior to Greys there were far stranger entities that entered the world, such as Flatswood Monster, Hairy Dwarves and even cases of giant robots abducting people..

sadly many are now following the "Aliens are actual Demons" conspiracy which damages the already fragile alien cryptid situation.

some non-alien  cryptids that can never be forgotten:
 * Melon Heads


 * Mothman


 * Skin-Walkers


 * Yeti


 * Sasquatch / Skunk Ape / Fouke Monster


 * Devil Monkeys


 * any and all sea-monsters, since the ocean is less explored than space itself.. look up the "Blip" for a sound so tremendously scary scientists had to "explain" it as icebergs scraping against ocean floor just so they didn't have to think on what else it could be.. we're talking critters that make blue whales look like small fries.
