|Appearances||The Ballad of Gay Tony|
Luis Fernando Lopez
|Businesses||Maisonette 9 (Security Management)|
|Voiced by||Maia McCann|
Joni is a female security manager who operates in Maisonette 9 along with Luis Lopez, Dessie, and Cindy. Luis keeps in touch with her via headset whilst scanning the dance floor from the security room for trouble in the side-mission Club Management, telling Luis to check out certain areas where she sees disturbances.
Occasionally, Joni will offer Luis sexual favors such as a strip tease, giving him oral sex, or have quickies with him.
- According to her, Luis has a "little guy" (referring to his penis size).
- Just like with any other club employee, killing Joni will cause her to respawn the next time you come back to Maisonette 9.
- If you purchase the Episodes from Liberty City (disc version), it comes with a poster of Joni on one side, and a map of Liberty City on the other.
- Joni appears in 'concept artwork' format multiple times holding a champagne bottle during The Ballad Of Gay Tony loading screen and boxart. Joni has the distinction of being one of the only women featured on the cover/loading screen art for a Grand Theft Auto game to actually be featured in the game itself.
