Oliver looked through Kara's reality and noticed quite a number of things that needed changing and once more began his usual clean up and restructuring as part of reviving the universes and merging his friends worlds.

First, he decided to erase the Kara, James, Winn, and Lucy love square since he did not see it as something that was absolutely necessary for them to go through and to him, since Kara was just starting out as a hero, she needed to focus on her growth as one instead of being distracted by romance.

Instead they all saw each other as close siblings, except for James and Lucy, the latter two having still dated but went on to break up since they realized that they were two different people.

Plus, since Kara was now more devoted to her work as Supergirl, she was able to locate even more threats, a great many of them male and not just female, while also receiving training from other DEO members besides Alex and J'onn, a lot of them being male agents.

Next, and in order to make life easier for her and her loved ones and allies, he erased Cadmus from existence and turned Lillian into a good woman who aided Kara's team, saw Lex as responsible for his own actions, and was much kinder to Lena, starting when she was just a child.

He also, for the foster sisters own good, made certain that Kara spent plenty of time with the rest of her loved ones and allies instead of just her then boyfriend Mon-El and her bff Lena while also having Alex do the same instead of occupying most of her time in romantic moments and hangouts with her then girlfriend Maggie. Not to mention having Kara and Alex have plenty of good doses of quality time together.

Next, he looked at Kara and Lena's relationship and saw that it needed some improvement, particularly on Kara's end, and especially for the purpose of preventing any unnecessary fallouts, wrongdoing on either end, or messes.

And so he decided to also rewrite Kara's personality and so doing, erased all of her self-righteousness, arrogance, and holier than thou complex. And so she ended up calmly discussing with Lena certain things like why the latter created Kryptonite and Lena also hiding what was going on with Sam, and then allowed her bff to explain her reasons. That in turn helped improve their relationship and made it even healthier than it already was.

And with their bond strengthened and deepened, Lena in turn truly gave Kara the chance to explain her own reasons as to why she withheld her Supergirl identity from the former after Lex had revealed to her the truth. And while Lena was still angry in this new reality, she would not be as angry, particularly since Kara had fully proved that she trusted her bff in other matters while lacking arrogance, and would instead allow herself to reconcile with Kara, further strengthening their bond.

Oliver also made it a point to deepen Mon-El's maturity when he returned from the future so that he did right by his wife instead of still making heart eyes towards Kara.

Following this, the former Arrow, now the Spectre, decided to save Ben Lockwood from his dark path by preventing the series of events that would transform him into Agent Liberty. That in turn erased the Children Of Liberty and their anti-alien movement from existence while also preventing the murder of Manchester Black's alien fiancé.

While that reality of Manchester's life was rewritten, his fiancé however was severely injured by another villain and it caused him to go down the same dark path he had originally while still forming the Elite, leading to a war with Supergirl in which he challenged her on whether or not using extreme and lethal measures against enemies was justifiable, which she disagreed on and especially since his methods led to an great amount of collateral damage. But she and her team eventually defeated and incapacitated him and his team.

Oliver also considered erasing the alien run terrorist organization/cabal known as Leviathan from existence, but refrained from doing so since Kara's conflict with them was one of the contributing factors for her reconciliation with Lena.

All of this completed for Kara's reality, Oliver worked on a few other things here and there, making slight changes where necessary. And one of those involved moving up and expanding the private investigation Kate Kane and her team conducted into the murder of team member Luke Fox's father, the legendary Luscious Fox. And he also rewrote her reality a bit so that during her work as Batwoman, she received continuous training, guidance, and advice from Dick Grayson, the semi-retired Nightwing, and Barbara Gordon, the semi-retired Oracle.

Plus he also had Kate design her own suit and gather her own equipment instead of just claiming Bruce's equipment and suit.

Satisfied with the changes he'd made, Oliver completed his final mission and then died peacefully in the loving arms of his beloved wife Sara, while Barry, Kara, and Kate knelt beside them in respect as they silently paid tribute to a man who had inspired so many, directly and indirectly launched a new generation of heroes, and had now made the greatest sacrifice of all so that all of them would have a second chance at life.

And when it was all over and they and their fellow Paragons awakened in their new reality, none of them remembered anything of their past lives, only the new lives Oliver had created for them. And frankly, they were all better off for it while Oliver, from the afterlife, looked down upon all of them with a smile, pleased with his work. For he had not only revived the universe, but bettered it for his loved one and allies.

The End

A/N And that's the end of this story. As for how the "Supergirl" and "Batwoman" realities now appear, and starting with the former:

S1- As it was written, but without a love square. And with Kara facing more male villains and being trained by plenty of male agents, it's not too female empowerment focused and instead has more of an equal amount of respect and attention towards both its male and female characters.

S2- More or less as we remember, but no one sided political overlay of any kind since there's no Cadmus and Lillian is good, and no turning into the Karamel and Sanvers, or should I say the Karamel, Sanvers, and platonic Supercorp, show since Kara and Alex spend more time with other people besides Mon-El, Lena, and Maggie.

S3- Same as canon but without the Kara/Mon-El/Imra triangle while Kara never once becomes self-righteous. And so her giving Lena the business over her use of Kryptonite does not happen.

S4- No Children Of Liberty arc and in turn, no political anything [I liked the Children Of Liberty arc personally but since I understand politics don't need to be in fantasy, it's been erased]. Instead, the first half of the season was Kara and Superfriends vs the Elite while Manchester's the big bad, and the back half was Kara vs Red Daughter and Kasnia while Red Daughter's the big bad. And Lex pulls the strings within both arcs.

S5- Almost exactly the same as in canon, except that, and due to the aftereffects of S3's new reality Lena, while angry, does not turn into an anti-villain over Kara's secret and there's no Non Nocere arc while the two women reconcile in the middle of the season.

Regarding "Batwoman", and due to Oliver moving up the Lucius investigation, the first half is not SJW centered due to wokeness and lgbt focus while the back half is more gritty crime drama and mystery centered like in canon. Instead, both halves together are gritty crime drama centered while the main story revolves around Lucius's mysterious death.

And with Kate's time taken by Dick and Barbara, who are also a part of the first season, regularly training her, she does not have time for a love life. Plus she creates and collects her own suit and supplies for her mission.

So what did everyone think of this, and as a 100th story? Good, a terrible flop, or average? Please let me know in the reviews if you'd like. And if anyone's wondering as to why Oliver did not erase all of the villains or dark elements, it's because this is an Arrowverse corrections story and a canon series usually has to have its threats and big bads. But to explain within this story, certain things still have to happen or be replaced so that the universe can have balance, and Oliver understands it, especially as the Spectre.

I'd also like to thank everyone here who's left favorites and follows. I appreciate it.

Have a wonderful day.
