Drone (Dyosmos)

The Dyosmos Drone, also referred to as the alien, was a Xenomorph that was impregnated into Collin Hunter by a facehugger. The drone would go on to grow into an adult and kill a majority of the Andromeda crew before being killed in the self destruction of the Andromeda.

Birth
The drone was born through Collin Hunter after he was attacked by a facehugger alien and was impregnated. When he was impregnated, he gave birth to the drone, where it left his body and ran away to grow bigger.

Rampage on the Andromeda
When it grew up in the hours to come, the Drone killed it's first target, Joshua Claveria, in the kitchens. Before it could be caught, the drone took Josh into the vents and place him in it's alien nest on Deck 4. It's next kill was Timothy Knighten, after they attempted to trap it in Airlock B. After Timothy, the drone killed Baffour in an attempt to kill it aboard the Ore Refinery. The drone was shot and it's acid blood killed Baffour who was in the cross fire.

Next, was Evan Harris, who was killed by the Drone after he ran away from Bruce and locked the door behind him. When the remaining crew decided to self destruct the ship, the Drone ambushed Michael and Mason as they tried to get fuel tanks for the shuttle. It killed both of them within a matter of seconds, causing Rose to hurry and grab the tanks herself. The drone tried to kill the last four survivors in one last attempt as they ran for the shuttle. As they boarded the shuttle about to take off, the drone tried to enter by entering through the left thruster, but was launched back into the Andromeda after it took off. The drone was killed once the Andromeda blew up.
