Raised by Wolves (Mother impersonates and weaponises)

The first time she realizes fully that she is necromancer (an android designed to kill) she is threatened by humans that arrive on her planet and wanting to take her son Campion away from her. The failed attempt unleashes her "true nature" where she kills the humans invading her home, takes their space ship to attack the Ark (the mothership with all the remaining humans left from the war). She is able to take on Marcus`s (one of the human soldiers) appearances as she is approaching the Ark and the people on board let`s her in. As she docks, she shreds the faked apperance and murders everybody that she encounters on board (except for a group of children). She enters the main control room, where a group of humans in a futile attempt try to defend themselves. She blasts them all with her sonar screams. She wants the Ark to crashland, but the command needs a Retina confirmation. She finds a human that is hiding from her, tears of his eyelid and slams his face on the retina scanner. The system approves and sends the Ark crashing down on the Kepler-22 planet.
