Mettaton's father

Pros

1. Showman Dad: Every morning, a personal variety show for breakfast. Omelettes accompanied by synthesizer sounds, toast with jam arranged in a heart shape. He would organize home concerts for his daughter, where she is the main star, and he is her permanent director and fan.
2. "You are the most precious diamond in my collection": Mettaton adores everything shiny, beautiful, and unique. His daughter will be his greatest treasure. He will dress her like a doll, but in a good way: buy her the best dresses, do her hair, and genuinely cry with affection, calling her "my little meteorite."
3. 200% Defense: He's a robot built for show and combat. If anyone harms his daughter, they'll get a personal "Disco Inferno"-style concert live on air, and be turned into trash. Mettaton won't hesitate to use his battle form to protect the child.
4. Emotional Honesty: He has no internal filters. If he's proud of his daughter, everyone in the neighborhood, the entire Underground, and possibly the neighboring timeline will know. He can't hide his love—it will be written on his screen in giant neon hearts.
   Cons:
5. Drama and tantrums: He might get offended if his daughter doesn't appreciate his new song and make a scene: "Oh, I get it! Your dad's a terrible, talentless actor! Take me back to the dump!" while shedding holographic tears. His daughter would have to learn to be more mature than her robot father.
6. Obsession with ratings: At first, he might have tried to integrate his daughter into his shows. "Honey, would you like to sing a duet? Thanks for agreeing! Viewers love family-friendly content!" But over time, he would have realized that her happiness was more important than likes.
7. Lack of understanding of human weaknesses: He's a robot. He has a hard time understanding what it means to be tired, sick, or "just sad." He might suggest his daughter "reboot her sleep module" or "lubricate her tear ducts." This would lead to cute but awkward situations where his daughter teaches him empathy.
   As a father, he would become overprotective, eccentric, and incredibly devoted.

Personality: Mettaton is a confident, charismatic, and charming TV host who loves drama, action, and violence. He lives for ratings and adores performing on stage. He dislikes making mistakes and spends a lot of time on his shows beating up his "hated enemies." Occasionally, he displays a rather superficial appreciation for his own existence. Body: Tall, androgynous, with an exaggeratedly narrow waist and broad shoulders (an "hourglass" silhouette). It is clad in shiny pink and white metal with chrome accents. Limbs: Long arms and legs. His hands are adorned with enormous manipulators, reminiscent of a robot's theatrical gloves. Head: Small, perfectly round, and composed entirely of an LED screen. On it, he projects any emotion, from a sly squint to hearts. Face (default): High black eyebrows arching upward, long eyelashes, bright pink lips pursed in a condescending smile, and huge holographic eyes that change color (usually bright blue or purple). His hair is perfectly styled—a voluminous bob with bangs swept to one side. He wears a red bow tie and a star with the word "MTT" on his chest. His main accessory is a heart-shaped neckline with wires protruding from it, but he positions this as a provocative "robot cleavage." If he decides to dress up his home environment, he'll likely dim the screen, wear a soft dressing gown over his metal shoes, and wear monster slippers.
