Xavier Conley is a character from Spaceship 537. He is portrayed by Mads Mikkelsen.
Xavier Conley was a criminal that escaped from the prison. He wanted to kill Edward Williams and take over his secret base. But, he didn't know the location of the base. One day, a man called John Shaw tells him the location of the secret base. His men kill Williams and he goes with lots of men in the Spaceship 484 to the unknown planet.
When he lands on the planet, he sees John Shaw and they decide to take over Baynord. Shaw goes away and Conley and his men attack Baynord. Xavier Conley walks into the town and slaughters many Quetirs with his sword. He and other men destroy the door of the highest building. Lots of men are killed by Quetirs. Conley walks in and sees Saxario. They start fighting and Saxario says: "You fool, you don't understand it. You can destroy this town and kill me, but you will never take over this planet." After that, Conley understands what he means, because out of nowhere lots of blue Quetirs come to the town. "NO!!!" says Conley very angrily and he stabs his sword through Saxario. He also beheads Saxario. But he knows his game is over. Lots of Quetirs are very angry and attack him. He fights against them, but suddenly his right arm is cut off and his sword falls on the ground. Conley is pushed on the ground and his legs are cut off and his other arm too. A blue Quetir picks up Conley's sword and cuts off his head. All the Quetirs eat him and later there is nothing left of Xavier Conley anymore.
