Specific Expansion Needed: Needs AVP, Predator F&S and Omega plot info
Galgo Helder was the Chief Security Officer of the Geryon sent on a 'salvage mission' on the moon LV-223. After he and fellow crewmembers Higgins and Piper abandon and murder the rest of the crew of the Geryon, Galgo encounters a Predator whom he dubbed Ahab that forced him to work with him in hunting down a lone Engineer.
On the day of their arrival, Galgo is being the center of attention in the briefing room by telling the rest of the crew an embarrassing story of Piper until Captain Angela Foster announces three hours until touchdown.
Higgins alongside the crew land on the moon and begin exploring the terrain and are met with a lush jungle, bristling with strange alien life. They later come across a field of deceased mauled creatures and a lake of black goo. Galgo suggests that considering how deadly the former looked, the killers must have been a severe threat.
The prime discovery made by the crew however was an old vessel from the colony Hadley's Hope located on the neighboring moon LV-426 — containing a horde of hostile Xenomorphs which they unwittingly unleash. The Xenos kill and wound multiple crewmembers, but Galgo and others manage to escape as Galgo provides covering fire.
As they fled across a series of connected natural arches over a lake, Steinberg and three others fell in, where they were attacked by "Sharks". Galgo, Higgins and Piper shot at the creatures, managing to save Steinberg.
They eventually retreat into the Helios and captain Angela reveals her true intentions in travelling to LV-223 - to find the truth behind the Engineers. Galgo and Higgins in particular were outraged by this.
The team mount a rescue mission for Francis and his construct assistant Elden, whom had split up from the group. They encounter the crashed crashed alien ship. Whilst exploring the interior of the ship, Galgo finds and keeps a large Engineer rifle-like firearm.
The Helios is later attacked by Xenomorphs and Angela makes a change of plan to return to the vessel and fight the creatures. Coincidentally, Francis encounters the group and he admits to injecting Elden with the black goo. Higgins and Piper seize Francis and Angela has him under arrest.
During their walk back to the ship, Galgo is suddenly attacked by a monkey-like creature, a species that the crew had previously encountered. The creature clawed Galgo's face, scarring him.
The crew is met with a Helios completely surrounded by Xenomorphs. Angela suggests that Galgo, Piper and Higgins return to the Perses to use the ship to drive off the aliens using it's weaponry, whilst putting Francis in lockdown.
On his way to the Perses, Galgo separates from Piper, Higgins and Francis and suddenly comes into a close-encounter with an Engineer. The Engineer is stacking a large number of dead Xenomorphs onto a pile. Galgo manages to hide from it and escape unnoticed.
Whilst waiting for Galgo's backup, Angela and others witness an unhinged Elden approach the surrounded Helios and the Xenomorphs allow him to open the hatch to the ship. As the Xenomorphs flood into the ship, Angela contacts Galgo, asking him what he's doing. Galgo initially doesn't answer but Higgins convinces him to. Galgo tells her that he, Piper and Higgins took a vote to abandon the rest of the crew and take off from the moon, leaving the devastated captain with a "good luck down there. And goodbye".
Whats left of the crew of the Helios manage to escape on ATVs and they regroup with Angela's crew on the juggernaut. Angela contacts crewmember Treynor back on the Kadmos in the Geryon for evac, but Galgo, Piper and Higgins board the ship and murder him, knowing that if Angela and the rest survived, the three would obviously be "court-martialed".
Galgo is initially shown to be a boastful, egotistic and over-confident individual as he claims to be a brave person, much like William Hudson. Instead, he is in reality, a coward who prefers to run from trouble rather than fight it head on, unlike his more braver friend Piper.
