I think Robbie is actually a minor character from Guilty Gear Begin. A friend of mine has been working on translating the novel. Apparently he's a polish (?) researcher that was loosely involved with the gear project and had some kind of familial (?) relationship with Vince. I'm not entirely sure on this (Also, Robbie might not be his direct name, you know how it is with accurately transcribing character names from japanese), but this seems to be the most likely case.
Mhhhh... must’ve missed that part. Yeah that’s pretty obscure. Thanks for picking up on it and correcting me.
I haven’t fully read through the Spanish translation yet, I just had a rough summary to go on.
SPOILERS TO THE GGBEGIN NOVEL AHEAD, YOU HAVE BEEN WARNED!!!
Okay, as far as I understand things were supposed to go like this:
1. Asuka made a contingency plan in case the U.S. Government or some other group would make an attempt on stealing his Gear Cell Research.
2. He entrusted Frederick with the job of sending that data to Vince MacDonell before the military could get their hands on it. He also framed Frederick as the “leaker” of that data (stating that the Military group supporting him would need to kill Frederick as a witness).
3. Just after Frederick was successful in “sending” the data he smuggled out of the lab, he was “assassinated” by Asuka with a group of Military Soldiers present, but what they didn’t know was that the Bullet that killed Frederick also contained the Flame of Corruption Seed/Gear Cell information that would transform Frederick’s body in to a Gear.
After the conversion was complete, Frederick woke up in a pool of his own blood. A good amount of time had passed between when he was “killed” and when he “woke up” again, and he had a case of amnesia as a result.
4. After the “data” from Frederick was sent to Vince, it was intercepted by the CIA who were investigating rogue military elements that had broken off from their organization in order to steal the Gear Cell Research.
In an attempt to investigate what happened, they sent in CIA agent member Viidia. Viidia tried to find out what happened (disguised as a Scientist) but got locked in one of the labs until Frederick found her.
5. After the Gear Owls incident and the elevator shaft incident, they found the entrance to Section Gamma but it’s flooded and has Gear Crocodiles which force them to retreat back up the stairs just as another explosion in the underground complex occurs.
6. Confirming his suspicions of Viidia, Frederick interrogates her, and she finally confesses the truth about being a CIA agent, but also that Sarge is not a Scientist either, but one of the rogue soldiers that was trying to steal Gear Cell Research.
Out of options, Sarge shoots Dustin Barrie (one of the surviving scientists) and tries to kill Viidia, but Frederick breaks his wrist.
The remaining scientists in the group feel compelled to rely on Sarge as their main method of escaping the facility, but Sarge reveals there isn’t much time left before the Facility is destroyed. Sarge also reveals that it was Asuka who shot Frederick and was probably the one who turned him in to a monster Gear.
Unable to believe Sarge’s words, Frederick decides to confront Asuka directly.
Later, entering a T-junction near Section Gamma, Sarge set a trap for the surviving Scientists, as he had anticipated another complex explosion and had them caught up in it... using the hole from the blast to escape in to Section Gamma proper.
Frederick and Viidia managed to survive the blast, but give chase after Sarge when he escapes.
7. Frederick and Viidia chased Sarge to the 6th Special Laboratory where they see a lot of dead bodies. Sarge unleashes a Gear Grizzly Bear from one of the research pods, and its ability to heal rivals Frederick’s.
During the struggle, they try to engage the Bear, but nothing works. They even tried getting the bear to attack Sarge, but he was wearing a bracelet that allowed him to give orders to the Bear, and so the Bear would never attack him.
Frederick is knocked near a hole in the lab, and Viidia gets an idea to trick the Bear in to falling in to the hole... it works, but only temporarily. The Bear grows Gear tentacles and pierces Viidia’s chest climbing on the way back up, mortally wounding her.
Before she dies, she makes Frederick promise to do everything he can to stop the military... finally giving in to his destructive impulses, Frederick chants “Dragon Install” for the first time.
With this power, Frederick is now on equal terms with the Bear. Witnessing the uncanny fight before him, Sarge grows fearful and runs to the escape ship to get to the surface.
8. Asuka witnesses the battle from within the escape ship, and is now certain Frederick won’t die.
Sarge confronts Asuka, stating he tried to pull a fast one and turned Frederick in to a Gear, but Asuka doesn’t give a straight answer. Knowing he still needs the military’s resources to save Aria, Asuka convinces Sarge by speaking to Frederick via a com unit, telling him he wants him “to please die”.
Frederick hears the words from Asuka via the intercom but isn’t convinced, despite having killed the Bear he was just fighting.
Just prior to the ship’s launch phase and escape, Frederick manages to grab on to the edge of the ship’s platform...
Sarge tries to shoot Frederick but misses, but then Asuka takes Sarge’s gun and points it at Frederick coldly.
Unable to believe what’s happening, Frederick pleads with Asuka to stop.
Asuka, with no other choice to maintain his façade, shoots Frederick squarely in the head.
Frederick falls from the escaping ship and tumbles down the shaft to the bottom, screaming Asuka’s name and demanding why...
The facility explodes and the rubble falls on top of Frederick, burying him alive.
Afterwards, Frederick climbs his way out of the collapsed underground tunnel, swearing revenge on his former best friend. He escapes the area before rescue sirens come to the area.
Sometime later, Frederick is seen building his Limiter in a run-down shack.
As for Robbie, I can’t confirm if he has any connection with Vince Macdonell or not. I’d have to look further in to it. But thanks for pointing this out, nonetheless.
Suffice to say, the CIA and the rest of the American Government froze the project for a time... that is, until the 2040s when they became desperate for a fresh Military Program.
