Biography
Only a little is known about Lazarus 92's history, but it is an intergalactic criminal who was eventually captured by the authorities at some point. Unfortunately, a large asteroid hit the spacecraft it was being transported on, causing the ship to crash-land on Earth. It is implied the creature escaped shortly after, killing the other prisoners and crew members alike.

Eventually, Jack and Ashi encountered Lazarus 92 while taking refuge inside the ship from a sandstorm. Initially unable to defeat it due to its regenerative abilities, Jack discovered a device in the ship's armory that could permanently destroy Lazarus 92, but failed to learn its activation sequence due to Ashi misfiring a laser rifle. As the two were overwhelmed by the monster, Jack finally managed to activate the weapon, killing Lazarus 92 with a massive jolt of electricity.
