Terrormisu

Tiaramisu/Terrormisu is the final boss of Wario: Master of Disguise. In her human form, she's a woman with blond hair who wears a mask over her eyes. Her dress vaguely resembles a red version of Princess Peach's. In her demon form, she looks even more like Peach, except with a fake, more beautiful face covering the form's true hideous face. She also appears slightly more heavyset than most female Mario or Wario characters. Tiaramisu's name is a pun on "tiramisu," a Italian dessert, and "tiara," though she doesn't wear one. The names of Cannoli and Carpaccio, also introduced in Wario: Master of Disguise, reference Italian foods as well.

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.

In-game Description
''This is the evil demon of legend that was sealed inside the Wishstone. Hubba hubba.''
