Beetlejuice

I was named after the star Betelgeuse. I'm able to draw shapes, transform and conjure objects, alter my art, and perform other feats of magic, although my powers can be reduced by various circumstances, such as when I feels fear, or when my head becomes separated from my mind. Give me a moon rock say Beetlejuice thrice and behold the outcome... magic or terror that's up to the beholder... The key to summoning him is “Beetlejuice” thrice. Saying his name 3 times stresses how much he is wanted and acts like some sort of a “contract.” So, once he starts drawing, you couldn't raise the defense that you summoned him by accident.
