A Pollination Technician is a member of an alien civilisation, who can be referred to as any member of the crew of the UFOs that abduct Sims stargazing through a telescope at night. A Pollination Technician is the other parent to alien-Sim hybrid babies caused by abduction. They can impregnate male Sims with advanced technology.
Each neighbourhood has its own Pollination Technician. The Pollination Technician does not actually exist as a Sim in the game, but only as a set of DNA that is passed on to alien-Sim hybrid children. Unless mods are used, a neighbourhood only has one Pollination Technician; by default, all alien-Sim hybrids in a neighbourhood that were born through alien abduction are either half, or full siblings.
The numbered Pollination Technicians in Pleasantview and Strangetown are part of pre-created families, and are separate from the NPC Pollination Technician.
When a Sim is impregnated by a Pollination Technician after being abducted, the Pollination Technician will be anonymous, but will appear in the hybrid child's family tree.
The Pollination Technician can be removed from the family tree of an alien-Sim hybrid toddler or child if that hybrid toddler or child is taken away by the Social Worker and later adopted. When this happens, the Technician and the birth father will both be replaced by the members of the adopting couple. Also, programs such as SimPE can be used to remove the Pollination Technician from the family tree.
The Pollination Technician will never appear as deceased in a Sim's family tree. In every neighbourhood, he has no age bar. The only exception being Strangetown where he is an adult. A mod that unlocks the hidden alien face template the Pollination Technician uses can be downloaded here. Note that the ears of the default template are normal sized, as the Pollination Technician's ears are customised.
In the Swedish and Norwegian translation of the game, the Pollination Technician has the number 11 at the end of his name, named as Pollineringstekniker 11. In the Finnish translation of the game he has number 12 at the end of his named, as Hedelmöitysteknikko numero 12.
