* GrievousHarmWithABody: The Divine Wind melee weapon has you [[Creator/StuartAshen tear your Gear's arms off and throw them at people]].

* SlidingScaleOfIdealismVersusCynicism: InUniverse. The Hiryu Islands sub-setting is the idealistic [[SuperRobotGenre Super Robot]] playground where goofy-looking villains square off against spiffy-looking experimental prototypes with HotBlooded teenage pilots; the Mobile Battleship Wagner sub-setting is closer to gritty-but-still-hopeful [[RealRobotGenre Real Robot]] anime, where both sides have good and bad people; and the Clarke Foundation sub-setting sits way at the cynical end, where pilot death is more likely than not, the pilots' employers can't be trusted, and the civilians are as likely to hinder the players' efforts as they are to help.

* GrievousHarmWithABody: The Divine Wind melee weapon has you tear your Gear's own limbs off and throw them at enemies.

* RocketPunch: Functionally, the Extending Punch, as well as any Melee weapon with the Returning feature.

* [[CyberneticsEatYourSoul Cybernetics Make You Bad at Socializing]]: Being a Cyborg makes you immune to the vacuum of space and most toxins and diseases, but impose a Disadvantage to Empathy rolls and Awareness rolls for Diplomacy or Deceit.

* FantasticNuke: The 3G bomb, which causes a catastrophic chain reaction in all the [[GreenRocks Gygravagnite]] within range, and makes the ground where it went off hideously radioactive. Given that all the mecha in the setting are powered by Element G, deploying this thing turns all the Gears around it into walking bombs.

It's the year 2100 and Earth is under siege. [[AlienInvasion The Outsiders]] have, after a 24-hour battle that annihilated most of humanity's space colonies, [[VichyEarth subjugated the United Earth Federation]]. Leaving the humans in the now-compliant Federation's [[CityNoir Safe Zones]], the Outsiders rove the planet looking for [[GreenRocks Gygravagnite]], which has near-miraculous energy-generating properties, and which is used as the fuel for the next generation of war machine: the [[FunWithAcronyms General Enforcement Anthropomorphic Robot]], or [[AMechByAnyOtherName Gear]].

It's the year 2100 and Earth is under siege. [[AlienInvasion The Outsiders]] have, after a 24-hour battle that annihilated most of humanity's space colonies, [[VichyEarth subjugated the United Earth Federation]]. The Outsiders themselves seem more interested in the mineral [[GreenRocks Gygravagnite]], which has near-miraculous energy-generating properties, and which is used as the fuel for the next generation of war machine: the [[FunWithAcronyms General Enforcement Anthropomorphic Robot]], or [[AMechByAnyOtherName Gear]].

Meanwhile, in the Verne colony cluster, the survivors are being terrorized by the [[OurMonstersAreDifferent Cryptids]], which appear seemingly out of nowhere and which steal both biomass and [[MindRape memories]] from those they attack. The only real defense against them are the [[OrganicTechnology strangely biological]] Gears produced by the mysterious Clarke Foundation.

** To start with, the game's name (or at least the name's initials) are a reference to [[GaoGaiGar King Of Braves GaoGaiGar]], and the cover is a shout out to SuperRobotWars.

Outside the Federation's upper echelons, however, humanity has not decided to take this quietly. The Hiryu Islands, situated in the Far West Archipelago right next door to the Outsiders' main ship, is deploying its [[SuperRobotGenre superpowered Gear prototypes]] in defense of the home islands from the Outsiders and their [[RoBeast Botakuri minions]], and the forces of the [[LaResistance Revolutionary United Front]], spearheaded by the Mobile Battleship Wagner and its [[RealRobotGenre ace Gear pilots]] are taking the fight to the oppressive Earth Federation.

* GreenRocks: Gygravagnite, an all-purpose energy source that the Outsiders seem to be obsessed with. In one suggested endgame scenario, it's suggested that every bit of Gygravagnite over a certain limit brings the heat death of the universe closer.

* TheRevolutionWillNotBeVilified: The RUF is clearly the good guy in the Wagner sub-setting.

* FantasyCounterpartCulture: The Hiryu Islands are pretty clearly an idealized version of Japan.

* CrapsackWorld: Outside of Hiryu, the world's in rough shape. The global government takes its orders from aliens, the few population centers are hellish slums outside of the Sanctuary Districts, said government is entirely willing to nuke its citizens to keep the RUF from taking cities from them, and the few remaining space colonies are drowning themselves in [[BreadAndCircuses hedonism]] to distract themselves from both their stultifying lives and the literal monsters lurking in the shadows.

* BloodKnight: Julia Campbell, another of the pre-gen Rivals. She refuses to use ranged weaponry, preferring to mix it up in hand-to-hand combat, is unlikely to communicate with whoever she's fighting with except to taunt them, and will carry a serious grudge against anyone who forces her to retreat. Interestingly, she's also unwilling to go down in a blaze of glory, and if forced to listen, might actually switch sides if it would let her experience the thrill of battle more.

** The Micro Missile weapon's description refers to the [[MacrossMissileMassacre Itano Circus]] style of missile launches from SuperDimensionFortressMacross

** The Clarke Foundation sub-setting, with its mysterious MindRape-capable monsters, organic mecha, conspiratorial tone, and [[ArsonMurderAndJaywalking pilots referred to as Children]], is one giant shout-out to NeonGenesisEvangelion

* LuckManipulation Mechanic: Genre Points let you force your opponents to reroll for the worse, reroll your own attacks for the better, set up [[CombinationAttack Synchro Attacks]], upgrade your mecha mid-battle, and other things.
