The Alien Parasites are an unnamed group of aliens who invade and conquer planets by shape-shifting into the forms of various beings such as humans, aliens, animals, historical figures etc. and taking up a persona of them.

History

When alien parasites arrive on a planet, they implant people's minds with false memories of invented characters being people such as friends, family members, etc. Once they have multiplied enough, they use this to take over the planet and enslave the race. They invaded Earth and confronted the Smith family.

"These telepathic little bastards embed themselves into memories and multiply to take over planets! They're disgusting, so be careful of any wacky or zany characters that pop up".
—Rick explaining the parasites[src]

As Morty discovered, the parasites only implant perfect, friendly and happy memories into their victims. This means if someone cannot remember any bad memories of another person, the latter could be a parasite.

They also seem capable of suppressing other memories, particularly ones contradictory to memories they have implanted. One of the characters created, Sleepy Gary, replaces Jerry as Beth's husband, and for this to work any memories of Jerry as Beth's husband would need to be suppressed. When Rick threatened to kill Summer, Sleepy Gary stood in the way, shouting 'That is my daughter.'.
