Egg-layer

Egg-layers were the female queens of the Pünta species.

They were larger than the males, and possessed at least some female sex characteristics.

When human geneticist Alceste Leboissard was stranded on their home planet, he manipulated some egg-layer's biology so that they produced an entire new species of Human-Pünta hybrids who quickly became the dominant lifeform and created an advanced civilization.
