Its...very cringe. Its a continuation in the future of 'Nos meets Aurora and reforms'. My idea is that their friendship ends up developing to the point where they collect scrap together, and at some point her life winds up in danger and he saves her in public, and people cheer, and he gets a taste for heroics...because he finds it HILARIOUS to see both the fickle nature of people in general, and the Rangers realizing that he could have been a powerful ally all along if they'd just given him a chance instead of persecuting him for how he was built. The whole "You failed ME Rangers...but fret not, I'll play nice...if only to see that bewildered expression on your face" bit. Then...remember than episode where alternate universe versions of the team show up, with an evil Buzz and all that? Aurora tries an experiment that winds up sending them spiraling through the multiverse, landing in other dimensions and trying to work their way back home.
The story is set in an alternate universe where the Nos-4-a2 stayed dead after the wirewolf cannon incident, and follows THIS nos...Nos-4-a2.0, as he jokingly introduces himself, making amends to all the people his this-universe counterpart hurt, confusing them the whole while while being insufferably smug about being reformed...switching from falsely angelic to impishly amused as he tries to hold in his mirth.
The writing is awful, and there's little I can do to fix it. Nos's fluid, spastic movements, the quirky tone of the show, it doesn't translate well into writing. It starts with him rescuing Savvy SLQ and puts her out of character in doing so. Its too fast paced to make sense, and the tone switches back and forth too quickly. Its just...the epitome of 'bad fanfiction'. No real plot, just a series of events the writer wants to see, barely justified and clumsily connected, with some b level 'witty dialogue' thrown in for good measure.
I'll probably write more Nos, but that one...I can barely read it without rolling my eyes.
