Leta Lopez-Wilkinson is an unseen character in The Ballad of Gay Tony.
She was abandoned by her father along with her brothers and was sexually harassed by a teacher at her school, which resulted in Luis shooting the teacher and being sent to a juvenile detention center. Leta later moved out and married Mr. Wilkinson, and had an unknown amount of children. She works in a human resources department but tells Luis not to work in one as "people treat you like you need to wipe their asses".
Leta has a healthier relationship with Luis than their brother Ernesto and does not nag Luis about his nightclub lifestyle, unlike their mother and brother, which Luis admires. She later asks Luis to look out for their mother after admitting that she and Ernesto have not been there for her after moving out.
There are numerous pictures of Leta in her mother's house that are rather hard to view however, as they are only featured in cutscenes. If the player should look at this pictures in her mother's house, it can be seen that they feature different characters. One is wearing a light brown ski jacket and has light brown hair. (This character model can be found in North Holland.) A unique character model can also be seen, with long brown hair and a beige business suit. This is also the case with her brother, Ernesto.
- Henrique Bardas has a crush on Leta, one that has apparently stood since they were children. It is doubtful that these feelings are mutual.
- During one of the Club Management side missions, Dessie asks Luis to go pick up the Blue Brothers and bring them back to Maisonette 9. Luis complies, but states he's only doing so because his niece is crazy about them. It is likely Leta's daughter as Luis does not talk to Ernesto.
