Marty overhears Anne and Colonel Weaver discussing the Dornia weapon and the periodic table of elements and offers his help in figuring out the weapon. Weaver is skeptical as he'd worked in a brewery, but Marty reveals that he is also a biochemist. Marty and Anne run tests on the weapon and discover that it is deadly to all of their test rats and realize that it is so deadly, it could wipe out not just the Espheni but humanity too. Marty and Anne work on modifying the weapon to be non-lethal to humanity and he succeeds by mixing human enzymes into the weapon, having gotten the idea from the way he created beers at the brewery.

Due to Marty's modifications to the weapon, Tom is immune to the virus' effects and survives while the queen and the other Espheni are wiped out.

  • While introduced late in the series, Marty ultimately plays an essential role in the defeat of the Espheni: he discovers the Shadow Plane communications device which allows the 2nd Mass to hack the Espheni communications and discover the location of their queen. Marty later proves vital when he modifies the Dornia bioweapon so that it is non-lethal to humans and is thus a viable weapon against the Espheni. This proves vital as it allows Tom to infect the Espheni Queen by infecting himself with the weapon as she drains his blood. Since Marty made the weapon non-lethal to humans, Tom survives the experience.
  • Marty reveals that he used his skills as a biochemist to make better tasting beer at a brewery. Ironically, this talent proves useful as he uses the same method he used to make better-tasting beer to make the Dornia weapon non-lethal to humans.
