Nergal Jr.'s Bad Habit

After the two storylines based on "Nergal", the promo cards of both the base and the new advanced version of this Baali, I'll have to show this: "Nergal Jr." is a character from the animated show "The Grim Adventures of Bill and Mandy". To quote Wikipedia:

"Nergal Junior is the son of Nergal and Aunt Sis. He has the power to shapeshift. When he takes another's shape, he keeps his lime eyes, glasses, green tongue and sharp, yellow teeth. His true form is freakish and grotesque, and was never seen on-screen until in the episode "The Most Greatest Love Story Told Ever". Like his father, he is lonely and can't find friends, and because of his desperation, he developed evil tendencies and terrorizes everyone who stands in his way."
