Paper Tiger: UPEO is so woefully under-equipped that it has to receive "gifts" of military hardware from both sides just to stay competent, helpfully illustrated by the suffix "U" after the jets' names (eg, F-16XFU is basically General Resource's own F-16XF with a UPEO green paintjob, ditto R-101U from Neucom). The kicker? The donated equipments are as bog-standard bottom-shelf jets as they come. A hacked video feed even lampshades this ruthlessly.
Person A: Are these R-Numbers? They've got UPEO markings on it.
Person B: Well, there goes their so-called "neutrality".
The Player Character, who begins as a new pilot of SARF and quickly become known as an ace. Actually an AI created by Simon Orestes Cohen to simulate war and a single pilot's effects on it. The project is deemed a failure, though the effect on Nemo's acquaintances are far-reaching..
Tropes associated with Nemo:
And I Must Scream: The PC is a Tomato in the Mirror AI named Nemo designed by Simon of Neucom Inc. to be run in a simulated war and determine if one pilot can change the course of a war. In the end, Simon decided that no significant change could be achieved and he purged Nemo out of Electrosphere. After that, Nemo became nothing more than a mere simulator, cut off from the rest of the world and doomed to repeat the war simulation forever.
Ace Pilot: Already called "SARF's ace" by the fourth mission.
Heroic Mime: An odd case. People seem to act as if Nemo is in correspondence with them, though Nemo never says a word.
Spanner in the Works: Specifically, Dision's plan to groom Rena to pilot the massively overpowered X-49 Night Raven. After repeated contacts with Nemo, Rena becomes more determined to find her real memories. This proves crucial later on as she betrays Dision.
What Happened to the Mouse?: Assuming you do not take the UPEO route, he sort of "disappears" during the late stages of the game. If you are following the General Resource route though, you have the option of shooting him down, which does explain his absence. Otherwise...not so much.
What the Hell, Hero?: Erich calls Rena out for shooting down one of their own allies for suspicions of treason.
Wide-Eyed Idealist: Erich firmly believes in him protecting peace with UPEO. He's quite Genre Savvy about everything though, and when he has been used as a pawn too far, he flies with you and initiates a two-plane rebellion.
"Well, simply put, things are looking pretty dicey in the clouds. Later!"
A UPEO and later Neucom, if not killed pilot.
Tropes associated with Fiona:
The Chew Toy / Cosmic Plaything: She is pretty much the most ill-fated non-villain character in the game, as she gets killed in all but one ending, and unlike Rena's, it's a Downer Ending that leaves her broken and crying.
Badass Normal: Kinda. Of the three superfighter pilots in the game, she is the only one with a body of flesh and bone.
This is ultimately zig zagged. Rena is indeed the only flesh and bone pilot between you and Ai!Dision; On the other hand, Rena later pilots the X49 Night Raven, a Super Prototype "aircraft" with a laser cannon than can mow down aircraft with one or two shots.
Cloud Cuckoo Lander: She seems to go off on her own whenever she is flying with you and sends you various video messages. Apparently Dision has been messing with her mind.
Commentator: "Yes... you could say that leaders like UPEO Representative Clarkson are politician types from an age long gone. Since the USEA's unification by General Resource, in this age where the power of economics has exterminated government and law, his actions, to me are... well, I can only describe them as anachronistic."
The main peacekeeper, spokesman and chairman of UPEO.
"Some day, everyone will probably feel the limits of their body. Thatís not a bad thing. But those who have the mental strength to exceed that limit simply need not speak of it."
The great ace of General Resource.
Tropes associated with Abyssal Dision:
Ace Pilot: The best, next to the player. The player is, after all, a superior AI.
Ambiguously Evil: Second mission he's featured, and he's trying to get you to join his Company faction. No one knows if he's aligned fully with GR, aiding UPEO's chessmaster Park, or is all about himself. In the end, it's neither; he only wants revenge for his then girlfriend Yoko.
The Chessmaster: Not only did he try engineering you to join GR, he's also the head of Ouroboros, assists Park with his scheme to usurp control of UPEO, offs his own company's CEO, and basically grooms Rena to be the perfect Tykebomb.
Dead All Along: Shortly before her death, Yoko Inoue copied Human!Dision's consciousness into the Electrosphere, creating the self-aware AI!Dision, the first ever human to be Sublimed. Before she realized it, however, she and Human!Dision were killed by a bomb and their laboratory destroyed along with their research.
‹bermensch: The Dision you meet is actually an electronic AI copy of a flesh-and-blood Dision; this AI wants humanity to progress to an electronic form as he has, all while the Corporate War is heating up and he (it?) plays a part. Ultimately subverted, in that his ultimate goal is not to "advance the human race", but rather of Revenge against the companies who killed his flesh-and-blood counterpart's girlfriend, Yoko.
"Yo buddy. Not there again? Ah, whatever. Great job this time. No seriously, we were a good duo."
Tropes associated with Keith Bryan:
True Companions: He starts to salute you at the end of his video messages if you save him from troubles.
Taking You with Me: If the player sides with Ouroboros, Keith joins you, and attacks Dision and Rena. After he takes enough damage, he gets his plane stuck between the wings of Rena's Night Raven; when you shoot him down, Rena goes down too.
The Atoner: After her sister got offed by the organization she defected to, she performs a Heel-Face Turn from Ouroboros and singlehandedly (with you, of course) reversed the entire mess she has gotten into. It's even written in one of the mission name: Counterrevolution.
Fantastic Rank System: Cynthia's introduction video has her state that she is Neucom Emergency Unit's "Chief Consulting Pilot". It probablymakes sense considering the Mega Corp. nature of the setting, but still...
