This is going to another "Crisis" story of mine, set in Part 4, and when Oliver reset the multiverse and fixed things for his loved ones, allies, and the city.

You see, a though occurred to me sometime before I decided to write this, but what if Oliver, in addition to the changes he made for his family, allies, and city, but what if he'd also erased and fixed the problems that have plagued the Arrowverse in the past in regards to bad writing, character assassinations, and stupid writing?

And so I decided to do this for fun and have him erase all of the problems, including some that others felt were problems even I might respectfully disagree on some of those things. I hope you'll enjoy.

This will also be my 100th fic. That's right ladies and gentlemen. I've finally reached that milestone. I originally had two other plans for that but when writing this chapter, I ended up feeling that it would work as the 100th story since it's a crossover, which is what I'd envisioned, and plus a plot in which Oliver cleans up the Arrowverse seems to be a good place to mark this milestone.

Disclaimer: I don't own "Arrow", the "Crisis" crossover, or any of the Arrowverse.

As Oliver, now the powerful Spectre, was currently not only restoring the worlds of his friends but also merging them into one Earth, in addition to the Paragons helping in the restoration while also adding their own changes, he was making changes for his loved ones, allies, and city by erasing crime and reviving all of those who'd died tragically, among other things.

During the progress of this endeavor, a thought came to him which involved perhaps making certain other things better for his allies outside of his team and also rewriting their choices for their own good, feeling that their lives would be better off for it.

For the first changes, he looked at his own life and first erased his love triangle with Laurel and Tommy. Instead, he rewrote reality so that he never cheated with Sara but still took her with him on the boat since she had wanted to see the world, still setting events in motion that would transform them into the people they were and then when he returned home, he and Laurel resumed their relationship but then realized they both wanted different things, and so they broke up amicably and she eventually got with Tommy.

And then when Sara returned the next year, they realized their feelings for each other, got together, and would go on to marry six years later.

He also prevented Tommy from dying in the Undertaking and in turn, prevented Laurel from developing a drugs and alcohol addiction. And while he was at it, made certain that Thea would never become an addict either and at any point in her life.

Oliver also felt that when he and Sara had gotten together, he had not spent enough time with his loved ones and so made a point to do so and had Sara do the same with her family. Plus he made sure to save his mother's life when Slade almost murdered her.

Another thing he realized he should change involved him and Roy revealing their secrets to Thea and being more open with her, preventing her from going off with Malcolm and in turn, Sara's death and the League attacking his city. Though the change instead caused a turn of events in which a corrupt A.R.G.U.S. led by Amanda Waller besieged it and later tried to unleash the Alpha/Omega virus upon it in order to prevent the Triad, now controlled by Malcolm, from taking control of the city and using it as a base to link up with a ring of terrorist cells for the purpose of wreaking havoc across the nation.

Seeing this regrettable consequence, Oliver tweaked things by having Lyla and her honest faction join forces with him and his team in stopping both the Triad and Waller, along with Malcolm, killing Waller, and having Lyla installed as the new director.

Next he erased Damien Darhk's magic, forcing the latter to rely on his League training even more, which made Oliver defeating him easier since Sara and Nyssa had given him further League training in this new timeline. That also helped prevent Laurel from being murdered but, wanting her Earth-2 doppelganger to also have a chance at life, merged the two women together.

He also used his will in changing things to ensure that he would not succumb to Chase's torture and therefore keeping himself from falsely claiming that he liked killing. And as he did that, he thought of how he'd handled things when going after Chase's father and so tweaked things in order to prevent himself from slaughtering all of Claybourne's thugs and so brutally, instead only severely disabling them but without going over the top.

He did not erase Claybourne's death though since as far as he was concerned, that man deserved to die.

He also remembered to have Barry use his powers to collect and defuse the bombs throughout Lian Yu so that when Chase killed himself, the bombs did not detonate and William's mom, Samantha, did not die.

Next he prevented the murder of Cayden James's son and also erased Diaz from existence, Diaz being too dangerous to have ever existed and also the both of them being the masterminds of the cyber reign of terror over the city. Plus Diaz's death prevented Quentin from ever dying.

But since there must be balance in the universe, Dante, the head of the international and ancient terrorist organization/cabal, the Ninth Circle, ended up taking their place and attacked the city with their own, and multiple, cyberterrorist strikes that sent it reeling, Dante and the terrorist council over him having marked the city for death. But he was later murdered by his right hand woman Beatrice who then continued his plans by trying to start a fiery chain reaction to destroy it.

But in Oliver's rewritten reality, he had the combined might of the League, now led by Nyssa, and A.R.G.U.S., led by Lyla, who were able to help him eventually repel the Ninth Circle, stop and kill Beatrice and her own right hand man Virgil, and later destroy the organization.

During all of that, he also changed things so that Emiko was not groomed by Dante as a child and therefore did not grow up to become a villain. Instead, he made sure to have his parents do right by her, which also prevented her from dying due to making the wrong choices in life.

As for his imprisonment, and as painful as this decision was, he decided not to prevent it from happening since he knew it was needed in order for him to expose the corrupt and abusive practices of Slabside's level two.

Next, he made certain to erase the self-righteousness, arrogance, and hypocrisy of Felicity, Diggle, Quentin when he was that kind of person in the past, Laurel to an extent, and had already done so for Thea since her trusting him and Roy more, along with never going away with Malcolm, prevented her from developing that kind of attitude during the third year of his mission. And he had Felicity find a better way to clear Diggle's name other than joining Helix and so she never joined that organization. Ever.

Afterwards, he prevented Dinah and Vince from being discovered and captured by the criminal organization they were hunting, which in turn kept Vince from transforming into Vigilante, his death, and erased the Team Arrow civil war. Instead, he made certain that the couple would enjoy a peaceful life together, married with kids, and growing old together.

Finally, he erased all crime from his city post his seventh year back home, completely fulfilling his father's mission, and also erased the Deathstroke gang and in turn, the dystopian future that had his city turned into a near wasteland and overrun by gangs and corrupt cops, ensuring that Star City was a crime and corruption free, and sparkling, city that his children could call home.

Having improved his reality, somewhat, he then decided to get to work on Barry's reality.

To Be Continued

A/N So what does everyone think so far? I was originally going to have all of the changes be within one chapter but considering how long this chapter became, I've decided to give each show their changes within their own chapters. And so this will be a multi chaptered work.

Also, for anyone who would like a clearer picture of how Oliver changed things, here's an outline:

S1- Exactly as it was written, but no love triangle or Thea having a substance abuse problem.

S2- Same in regards to the writing, but with Tommy still alive, Laurel never having a substance abuse problem, and Oliver and Sara spending more time with their families since some had complained that S2 seemed more like the Oliver/Sara show rather than the "Arrow" show.

S3- Thea does not go off with a mass murderer and while knowing what he is when doing so, Sara does not die, and Waller with the Triad are the big bads instead of a neutered Ra's and League, in turn creating a stronger tie in with the pertaining flashbacks. When writing it, I ended up feeling that this plotline for S3 sounds even better than the League plot.

S4- Just as we remember it but no magic for Darhk and in turn, making it more of a grounded, gritty season like the others. And Laurel does not die while Sara's the Black Canary instead. And if you'd like an idea as to how Laurel's merged with her doppelganger, please check out my one shot entitled, "From Two To One: The Return And Rebirth Of Dinah Laurel Lance."

S5- Same writing but Oliver never says that he likes killing, Felicity does not work with Helix, and the island does not blow up in a poor choice of a cliffhanger since almost nobody important died.

S6- As it was written but with Dante as the big bad and behind the cyberterrorism, the city being overrun by the underworld and corruption, and Oliver's imprisonment. And Quentin does not die. As for Diaz, I personally really liked him as a villain but not everyone does and so that's why I erased him. But I feel that Oliver needed a good reason for doing so and so that's why I referred to him as too dangerous. But I still respect those who disagree and found him to be a poor villain.

S7- Same with the writing but with Beatrice as the big bad, instead of Emiko, her plan involving fire instead of a bio weapon to destroy the city, and the flash-forwards don't present a dystopian future.

Finally, Felicity in seasons 3-5 and 7a is more like both her S6 and flash-forwards self instead of what we remember, and Diggle, Laurel, Quentin, and Thea never become self-righteous either.

The next chapters will also have their own outlines regarding the changes of their respective seasons, and chapter two will be posted on Wednesday hopefully.
