Quantum singularity lifeforms

A list of quantum singularity lifeform individuals.

Female in Romulan form
This was a member of the quantum singularity lifeforms who took the form of a Romulan female. She was initially in sickbay, but later attacked Data in main engineering. She then disappeared. 

Male in Romulan form
One of these lifeforms assumed the form of a Romulan male. He would attack Geordi La Forge, almost killing him and leaving him with a neural shock. The alien explained later that a nest of their young had been mistakenly placed in the engine of the warbird, causing engine failure. The alien then disappeared. 

Nested young
This young quantum singularity lifeform was trapped in the engine core of a Romulan Warbird after it was inadvertently nested there. Two individuals of that species took Romulan form to save their trapped young and return it to their time.
