Plot of Super Robot Wars EXA

After long, bloody wars have polluted most of the Earth, humanity is sequestered in a portion of land that has grown into a large Metropolis simply called The Equalist Republic. Led by a despotic ruler called "DEM (promenteau of Deus Ex Machina)", The Equalist Republic manages to get by even during harshest of conflicts, except when the Resistance takes matters into their own hands and initiates a coup, emboldened by the addition of a very skilled robot pilot: Gaia. However, things get complicated when a nefarious third party called The Principality of Izan (the name was reversal from Nazi) seemingly aids DEM by supplying strange, often powerful technology, while at the same time pursuing the Gaia relentlessly.

'''Note: The fanfic that started it all, it contains mecha only and no pilots; essentially has an Excuse Plot and isn't counted in any timeline (Super Robot Wars). The fanfics nothing like its successors, being more of a traditional animated episides where the story IS altered from the original script. Unlike the SRW Series, the story is setting in the real world which mixed the alternate universe, original universe and The World of Darkness. The battlefields are altered as Warzone (its like Gundam Build Fighters and Killzone).'''
