XENO-MOM
The most nauseating of the Xenomorph species is the Xeno-Mom. Characterized by theirs acute ability to drive their offspring and everyone else around them insane with their obnoxious, never ending presence.
The Xeno-Mom is often seen hovering over their young far into adulthood; offering them unwelcome advice about anything and everything at every turn, until their young are finally forced to enroll into the college that will get them as far away from the Xeno-Mom as possible. After which, the process is repeated.
