The spotted Hyena.
These guys are the baddest predators around. Their reputation for brutality is like no other. The Hyena isn’t like a big cat, where it would typically ambush it’s prey; they would much rather chase their prey to the point of exhaustion. If they decide to put you on the menu, consider yourself dead. The spotted Hyena is known for running at speeds of up to 35 mph for miles on end. After being chased for a long period of time their prey collapses from exhaustion, and is now unable to fight back.
On top of their unmatched stamina, they’re believed to have a bite force of over 1,000 psi. That’s stronger than the bite of an African Lion, and around the level of a grizzly bear. To make matters worse, in the rare cases of ambush, they target the family jewels.
