Biography
After Ellen Ripley crash-landed on Fiorina 161 onboard a Type 337 EEV, the shuttle was recovered by the prison's staff. Unberknownst to anyone, a Facehugger lied within the shuttle. Spike sniffed the creature's smell and barked at it, until he was attacked, subdued and impregnated by the Facehugger. The dog was later found by Thomas Murphy, and his face was lacerated from his struggle with the Facehugger, to which he attributed to having been hurt by other inmates out of cruelty, later reporting this to Francis Aaron. During the improvised funeral held to Rebecca "Newt" Jorden and Corporal Dwayne Hicks, the Chestburster gestating inside of Spike emerged violently, immediatly killing the dog and escaping to the ventilations shafts of the facility.

Murphy became the almost immediate next victim of the xenomorph Runner, now fully grown, after mistaking its shadow for Spike's.
