You and your friends Craig, Clyde, jimmy and tweek are playing with an ouija board. It is late at night and it’s pouring down rain. You and your friends all move the pick, and it’s spells out tweeks name. Than a dark cloud of energy comes into tweeks body, a demon has possessed him. Tweek has a messy yellow hair and a green half unbuttoned shirt, but as the demon possesses him he grows red horns, a long tail, small wings and red glowing eyes, and is pretty skinny for a demon. He grows 10 times his original size, and is now 30 feet tall. Tweek is no longer himself anymore, he is possessed by an evil demon named belfigore from hell.

The demon looks at his new body and size, in surprise.

Ugh I possessed a kid?! he seems annoyed about his new form
