Shunka Warak'in
Montana
Derived from the Ioway Sioux myth 'shunka warak'in', which translates directly to 'carries off dogs'. Amateur taxidermist Joseph Sherwood dubbed it a 'ringdocus'.
It is a freakish, wolf-like beast with a nearly black coat bearing a hint of stripes on its flanks. Biologically, it features unusually short legs and a sloped back heavily resembling an African hyena.
Native to the Madison Valley of the Rocky Mountains in Montana.
A hyper-aggressive predator that actively snatched unwary dogs and attacked homestead livestock. When fatally wounded, it produced a terrifying, feminine scream and violently thrashed itself to death attempting to kill a pioneer family.
Shot by Israel Hutchins in 1886, its taxidermy mount became a legendary museum oddity. Modern cryptozoologists insisted it was an undocumented prehistoric survivor, but a similar beast shot in 2018 underwent DNA analysis and was proven to be nothing more than an ugly, purebred grey wolf.
