For the nebula entity, please see Debra (entity).
Debra was a 23rd century Human, the wife of Joseph M'Benga, and mother of Rukiya.
In 2248, Debra gave birth to her daughter Rukiya. (SNW: "Lift Us Where Suffering Cannot Reach")
In 2259 when the USS Enterprise encountered an entity believed to be a Boltzmann brain in the Jonisian Nebula, Rukiya named the entity Debra after her mother. Interacting with the entity meant Rukiya aged rapidly compared to her father, and when she appeared to him as an adult, he commented that she looked much like her mother. (SNW: "The Elysian Kingdom")
