Ebony is Tina’s rival. She is a dentist who wants to destroy Tina’s life due to her selfish nature. Her husband is Tacito who is a model for a magazine about men's clothes.
Ebony went to the same highschool of Tina. She bullied Tina and made her life horrible. When Tina and Gerald got together in high school, Ebony tried to steal Gerald away from Tina but failed each time. Gerald would just ignore her or sometimes flat out tell her off.
She tries to ruin the Teeth family business but fails because Tina will always catch her and give her a piece of her mind. Ebony has a son named Casimir who was only born to be a rival to Teeth. It backfired because Casimir and Teeth became good friends in high school.
If Ebony was at Cavity Con, she would throw a tantrum like a spoiled rich kid. Tacito and Casimir would drag her out of the building while saying sorry to everyone.
She had gotten her nose broken a bunch of times by Tina in high school and the early years of the dentist business. Ebony only got red wine poured on her white dress at a party by Gerald because she wouldn’t stop flirting with him. Tacito was there and laugh when she got the wine poured on her.
Tacito and Gerald get along without trouble. Over the years, Tacito has lost love for his wife and wants to divorce her but don’t because he don’t want to make Casimir unhappy
