Alexis was born into a loyalist Dominion family. She was recruited into the Dominion and chose to be a Terran Dominion Reaper. She served loyalty for a few years, never questioning order, never looking back at what she had to do. One day, all that changed. She and her squad was sent to eliminate a "rebel" outpost that was supposed to be helping Raynor's Raiders with weapons and so she and her squad brought death from above for everyone there. They had orders to kill everyone and those that fought died but as she was searching a warehouse that was supposed to be full of weapon crates, Alexis found something else. Women, children and elderly people. All unarmed. She radioed in and told her CO what she found and asked him what do to. The answer that came blew all her expectations "Kill them all" was the order. As her team moved in for the kill, she realized the truth. The Dominion lied about Raynor's Raiders. She opened fire on her team and took all of them out before they could do something as they were taken by surprise. She deserted and after some time, she joined Raynor's Raider and took the fight to the Dominion.
