Have you heard of a Cape Buffalo?
The are related to a domestic cows and kinda looks like them except they're about twice the size are far stronger and a lot more indestructible.
Animals that mooch around mulching grass can be easy prey for big cats or hyenas, so to stay safe buffaloes have an array of super tough defences such as sharp hooves, massive horns and in males a bony plate covering the skull.
When in danger Cape buffaloes will get together in a circle with their calves in the middle making it hard for predators to surround them.
Buffaloes especially young ones are often targeted by hungry lions who team up to hunt and catch them but the buffaloes aren't going down without a fight. Adults have been seen kicking and trampling lions to scare them off and rescue a baby buffalo.
They are bad tempered and if annoyed they make sure to get their revenge. In the past wild game hunters told tales of buffaloes being wounded then sneaking around behind the hunter later and charging at him to get their own back.
