Terrormisu

Terrormisu is a boss in Wario: Master of Disguise.

Biography
Long ago, a powerful and rich pharaoh by the name of Poobah the Pharaoh desired to have one wish granted, despite his immense wealth. To do so he summoned a demon by the name of Terrormisu from another dimension, who agreed to grant his wish. However, she would do this only if he made his people starve. He agreed, intent on his wish coming to fruition, and his kingdom collapsed. He expected his wish to be granted, but instead she had tricked him, stolen his riches, and left his kingdom in ruin. But then, a powerful wizard by the name of Cannoli the First appeared and used his powers to seal Terrormisu within the Wishstone, scattering the stone's pieces far across the globe to make sure that Terrormisu would never be able to return.

First appearance
She first appears in episode 7, "Fouling Up the Whole Works", warning Wario not to venture into the volcano. Later, in episode 8, "When Dolphins Ruled the Earth" she helps Wario advance through the boss fight. After this, she disappears, stating that her powers will not allow her to go any farther.

Second appearance
At the end of the final episode, Tiaramisu reveals herself to truly be a demon that was trapped within the Wishstone, and that her true name is Terrormisu. Now free, she plans to devour the souls of the world, but is defeated by Wario and Goodstyle. After the battle, Wario demands that she grant his wish, but she angrily flees back to her dimension, now no longer a threat to the world.

Third appearance
In Special Episode 5, Tiaramisu appears again, issuing a challenge for Wario and Count Cannoli to find her missing items, offering to give the one who does the most precious gem of her dimension.

However, when Wario is triumphant, she reveals that she considers herself to be the most precious jewel of her dimension, and, smitten with the Purple Wind, offers to join forces with him to conquer the world as King and Queen. Wario takes off running as the episode ends, with Terrormisu in pursuit.
