Thomas Draconius "Tom" Lucitor[15][16][1] is the demon prince of the Underworld and Star Butterfly's ex-boyfriend. Introduced as an antagonistic character to Marco Diaz, he has since become a recurring character and works with Marco to help Star attain her goals.Tom has spiky salmon-colored hair, very pale lilac skin, three red eyes (one in the middle of his forehead), black eyeliner under and around his eyes, two pale-orange white-tipped horns on the sides of his head, sharp teeth, and pointy ears and nose. In "Is Another Mystery", Tom is also revealed to have a long, red, pointed tail. Tom is considerably short-tempered, quick to lose said temper at the slightest provocation. When he is angry, Tom's eyes glow bright red, and he sometimes speaks in a low-pitched demonic voice. Since hiring his life coach Brian, however, Tom is shown to be much more in control of his anger, as evidenced by his 53-day anger-free streak. He initially has a very controlling personality, wanting things to go exactly the way he wants them; anything that deviates from his plans can set off his temper, even small things like Star not wanting to wear a spider on her head.
