Melle was a Deltan who served as a Section 31 operative in the early 24th century. She was a member of Alpha Team under Alok Sahar, alongside Quasi, Fuzz, and Zeph. As a Deltan, Melle had the ability to compel the affections of others, which she employed when the team needed a distraction.
In 2324, Alpha Team was dispatched to the Baraam to intercept a suspected bioweapon being sold by Dada Noe to the Minosian High Council. Melle was positioned in the nightclub when San attempted to seize the weapon, which was actually from the mirror universe. She engaged San, but he managed to get hold of her phaser and disintegrate her. (Star Trek: Section 31)
Melle was played by Humberly González.
