Krampus

"You've been naughty."

- Krampus

Krampus (KRAAM-puus; O.H.Ger. Krampen "claw") is an anti-Santa Wesen resembling a wild sheep and appeared in. According to legend he appears before Christmas and kidnaps naughty children who he keeps up in the tallest tree at the tallest spot. He does this with the intention of eating the children and then disappearing for a whole year.

Biology
When woged, Krampus chooses to wear a Santa outfit and has sharp teeth, curled horns, claws and a flaming red-forked tongue.

Despite his unique appearance and heavy outfit he is capable of high levels of stealth, as none of his victims were aware of his presence before he was announced and he could effortlessly disappear within a city despite being unable to guise himself as a human.

Krampus is extraordinarily strong, even by Wesen standards. He is capable of lifting struggling humans effortlessly with one hand and carrying them about with no discernible impairment. He is able to not only match blows with a Grimm but even gain the upper hand in a fight.

Behavior
Even among Wesen Krampus is unique. He is not aware that he is Krampus, or even Wesen. He is only able to woge from the first of December to the twenty-first when he enters a state of constant woge so fixed that even the loss of consciousness is unable to cause him to revert. It is during this time that Krampus can be said to actually exist.

Krampus hunts naughty children and adolescents, admonishing them for their bad behavior before beating them with a wooden switch and stuffing them in a large sack, leaving a large lump of coal behind at the abduction site. Upon abducting the children, Krampus hangs them from baskets like ornaments in the tallest tree in the tallest spot on the land with the intention of devouring them on the night of the Winter Solstice.

As Krampus exists for only three weeks out of every year and his human self is completely unaware of his Wesen self, Krampus has no culture of his own and is thought to be mythical even by other Wesen.

Excerpt from Wesen Fairytales
In the days leading up to Christmas, Krampus grabs naughty children, beats them with his switch and throws them into his sack.

He takes them deep into the forest and hangs them from the tallest tree.

Until he's ready to eat them on the eve of the winter solstice.
