Thomas Draconius "Tom" Lucitor 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.
From "Lint Catcher" to "Sad Teen Hotline", Tom and Star get together again before breaking up a second time.
Personality: 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. When not enraged, Tom can be rather easygoing, as he understands that Star might not want to go to the ball in "Blood Moon Ball" and is later willing to listen to Marco in "Mr. Candle Cares". In addition, he makes a genuine effort to overcome his anger issues in "Friendenemies", and he can be generous and compromising, as demonstrated when he resurrects Mackie Hand from the dead for Marco. Over time, Tom has grown to be an extremely understanding and respectful prince, determined to be a better person to his friends and subjects. In "Club Snubbed", he behaves gentlemanly and polite toward his fellow royals at the Silver Bell Ball, and he does his best to give Star her space and let her make her own decision. In "Demoncism", he tries to rid himself of his inner demons. These developments help Tom reconcile his relationship with Star again. Although "Monster Bash" shows that Tom still has problems with his temper, as he becomes annoyed at Star choosing to keep watch over the Mewman/monster gathering rather than spend time with him, he once again shows his growth by apologizing for his behavior and saving Star from Mina. Tom demonstrates further growth in "Lake House Fever" when he admits to Star that he knows about the kiss she shared with Marco in "Booth Buddies". Although he is hurt that Star didn't tell him herself, Tom shows patience and understanding toward the situation and wishes only to talk with Star about it. In "Junkin' Janna" and "A Boy and His DC-700XE", Tom seems to have security and self-esteem issues when not around Star, and he is perturbed over not being as "cool" as his peers in the Kill Devil Pass Riders Club.
