Rabbit of Caerbannog

"BEWARE! That's no ordinary Rabbit!"

The Rabbit of Caerbannog is an immensely cute but bloodthirsty rabbit-like monster and a prominent antagonist in Monty Python and the Holy Grail.

Biography
It is actually responsible for the deaths of many of King Arthur's men and acts as one of the movies main antagonists despite only appearing for a short period of time. The rabbit is also perhaps one of Monty Python's most murderous creations as it had a high body-count (especially for a comedy villain).

It was killed when King Arthur threw the Holy Hand Grenade of Antioch at it.

Behavior and Traits
This unpredictable "bunny" may look cute and cuddly on the outside, but inside, it is a monstrous killing machine. In spite of its bloodthirstiness and brutality, the rabbit appeared to be cunning at least for animal standards: When killing the knights, it often targets the vital parts of its victim's body to make a fast killing. Unlike regular rabbits, the mouth of Rabbit of Caerbannog was full of razor-sharp canines which similar with that of cats or other carnivorous animals.

The Rabbit of Caerbannog is surprisingly swift, violent, agile, deadly, aggressive, bloodthirsty, and carnivorous in close quarters: When attacking multiple foes, it quickly jumps to another target soon after swiftly attacking the first and giving those whom fight it no chance to stop it. The only way to killed it was through distance, as King Arthur killed it with a Holy Hand Grenade. It is unknown if other weapons like crossbows or arrows also work against it.

Cultural Impact
Ever since the Rabbit got popular, it has been used as an example of things that may seem good and innocent, but can in fact be extremely dangerous and murderous, and the fact that many different cuddly animals like the Killer Rabbit, can also have aggressive tendencies. In fact, only four years after the release of Monthy Python and the Holy Grail, a swamp rabbit attacked the US President Jimmy Carter while he was out fishing, and got the nickname "Killer Rabbit".
