Larry Purvis, played by Leland Orser, is a character in the film Alien Resurrection.
Purvis is a test subject who is kidnapped as an incubator for the facehuggers. After he is impregnated and rescued, Annalee Call offers to bring him along so he can be frozen and the Alien embryo surgically extracted later.
On the Betty, the survivors are ambushed and held at gunpoint by Dr. Mason Wren when Purvis goes into convulsions. He staggers over to Wren, who shoots him. Purvis stays on his feet and overpowers Wren, pulling the scientist's head to his chest. The Alien erupts through Purvis' rib cage and Wren's head, killing them both.
