What if Peter Parker ended up in another earth instead of being erased when Thanos snapped his fingers? An earth that was facing a grave threat of being taken over by a race of a hostile and powerful alien species known as the Kryptonians. The fate of the humans of this Earth lay on the shoulders of a certain blonde Kryptonian who had spent nearly an year fighting against her own race in order to keep her adopted home safe. Now, the war between Supergirl and Non and his army has reached it's final phase. The rouge Kryptonians have initiated Myriad and taken control over the minds of all people, leaving Kara all alone to fight for the future of this Earth. Caught right in the middle of the crossfire of this war and still dealing with the loss of his universe and loved ones, what will Peter decide to do? Will he help Kara in her fight to save the Earth? Or will he just try to find a way back home? How will the future pan out for our Friendly Neighborhood Web-slinger, and will it have the beautiful Girl of Steel in it? A SuperSpider Fanfiction!
