The problem with this story is you can skip 90% of it.

I have a question. Why were they trying to adapt krypton tech to earth tech. They have the knowledge of 28 galaxies and many species that are more advanced than human but less than krypton.

Why not find the tech from a planet a hundred year more advance then use that tech then advance that. It would have been easier to use stages.

This story doesn’t seem to be limited to just an HP-JL crossover. You’ve got the X-men, the Avengers, and even Twilight and TMNT elements in here, and all of it interconnected somehow with Harry’s life through a mix of time travel and retconning several key figures into women fated to kneel before the alter of Har-Zod, Master of Death, Kryptonian Sorcerer, and undisputed sex god of the universe. All that being said, I think I have a few suggestions for your next installment of this series. First off, I think it’s high time you had Harry form the Justice League, or whatever you decide to call the coalition of mostly female superheroes fighting alongside Harry Potter/Nightwing/the Dragon/Har-Zod, and I say mostly because I’m certain that outside of Batman and Martian Manhunter (I figured who “John Jones” is or might be right off the bat) and of course Nightwing himself, very few males will probably be with Harry’s Justice League. Secondly, let’s talk about how you’ve been retconning certain characters into women. I know from a few fourth wall jokes from Deadpool that you might be retconning Oliver Queen into a woman, and her name will probably be Olivia, but I think that if Thea Queen is the one to become Green Arrow then it might not be needed, like how you had Carol Danvers become Green Lantern instead of Hal Jordon because the latter was home sick with a cold or the flu or whatever it was. Makes me wonder which other principle characters you’re going to retcon into women, the Flash perhaps? Cyborg? Will She-Hulk make an appearance? Thirdly, I think it’s time for Raven and her mother to take a more active roll in this story, and perhaps between them and the Phoenix Force inside Jean Grey, and of course with aid from Wanda, it could be enough to finally fully heal the damage to Harry’s magical core caused by becoming the master of death at 14 years old. Fourthly, perhaps Starfire could make an appearance on earth like she does when the Teen Titans are founded, and she like so many others can be seduced by the unparalleled power of Har-Zod, just a thought, and perhaps her evil sister could fall victim to his charms as well. Speaking of female villains who have the hots for Harry, how about Mystique from the X-men? I’m sure she’d enjoy being with a man who would love her all night every night in her true blue form, like Harry will, and also Sinestra, because I think she would have joined the collective anyways at some point. Fifthly, I think it’s high time Harry went Kratos on Ares’ ass to rescue Aresia from his influence, I mean it’s not like he won’t have the support of like half of Olympus in doing so, and going back to a previous point perhaps as a reward for putting Ares in his place the goddesses can help fully heal Harry’s core if it hasn’t been done already by that point. Lastly, with Harry’s core fully healed him no longer needing that solar watch, perhaps you should have all of the kryptonians training themselves in restraint so they don’t need those watches either, or if you want to keep the watches that’s fine too. Speaking of watches, I have one more non DC and non Marvel element for you to consider adding to this world, the Omnitrix from the Ben 10 universe, but for the love of Hades DO NOT GIVE IT TO HARRY POTTER. Seriously, he’s massively overpowered as is, perhaps it should go to one of the girls without superpowers in Harry’s collective, or perhaps one of the girls under his care that’s too young yet to join the collective, Jesse Todd and Jade Crock are prime candidates in my opinion. Of course, should the Omnitrix be thrown into the mix here, along with probably the Ben 10 rogues’ gallery, I think you should stop at that for adding things into this fanfic universe. And that’s the end of my suggestions for the next installment, or two or three, of your Ascension series

Will Starfire join Harry’s collective? I know Raven will eventually, possibly even her mother as well, but what of Starfire and/or her sister, Blackfire?

ACCIO SOULGEMCASE. SUCCESSSSSS?
fuck dude.

The hypocrisy of Harry not Killing absolute scumbags like Joker or the Mad Hatter like he did to the Death Eaters is just killing me. Fucking turned your badass MC into a pushover to literally bends over for everyone. You having him "act" as an alpha is an illusion.

and of course you made them "forget" about the sister that is going to die now without financial aid.

Clearly you know nothing about legal cases because none of the evidence they were handed about Gorden through this anonymous person would be admissable in court. So they wouldn't arrest him over it because they would have to release him again.

You turned Harry into a complete pushover.
Also he previously used a freshly made bond to track someone but a super long bond to someone he MARRIED doesn't give him anything? right

Lmao twilight

Again, Nightwing was supposed to have gotten a bit stronger after Halloween but he gets his ass kicked by A Bane not even using Venom. But a while back he managed to win against Grundy while being weaker than he is now? This shit just doesn't make sense dude. Senseless nerfing.

Like, how does Nightwing just get casually grabbed at the back of his neck. Grabbing is one of the harder things to do in combat and he's supposed to be a kick-ass martial artist that can win against diana and queen amazoness

lol he just MYSTERIOUSLY got snuck up on by an amateur? And this is trained by the League in awareness and combat? Right, plothole much.

Awww no rachel in the Harem, erm collective. Harry needs more psycho girls willing to do his dirty work. You've kinda turned him into a hypocrite. He used to fucking kill all the useless scum back in magical britain but now he"s suddenly a softy?

Umm, sorry, fucking Harry Potter, Master of Death, wizard, kryptonian got fucking paralyzed for 20 FUCKING MINUTES? From a random mob putting his finger in his shadow.
RIIIIIIIIGHT
