AN : Well, English is my third language but... I figured I owe you guys some explanations.

First, this is my Bonus chapter series, In which I do explain a few things.

Today's Bonus is the original concepts behind this...

Now, at first, Thor wasn't the only one, he had teammates, who skipped ship, Toga and Twice joined them, and they went to the heroes side...

But then, I thought, that's too cliche and boring. So, I decided, maybe Izuku should be a villain? And I got too inspired...

However, that story was too dark of an AU.. He had suffered too much, and I felt sorry for the kid. So, the best way was... He retains his heroic spirit, even when he works with the villains, becoming Their hero in the process...

And it was like a charm. I found myself developping an entire plot, and it felt... Amazingly good. So, this would be my Beta. The Omega phases are now officially over.

Now, let's talk about Izuku in this AU... Thor, his old team's captain knew AFO for.. Centuries, or Century? I don't know how old that evil man is... One advice the old Anti-hero offered him, was to try and give life. So, how does Shigaraki, who's first name and even last name forgotten? He get a new family name and he uses his true name : Hisashi.

Somehow, I sure hope he's Izuku's canonical father...

But yeah. One thing led to another, he and Inko... Kinda broke off, but he never divorced her since he didn't want to lose the one woman who made him remember that he was human too... So, he told her that he'll go for a business trip, and he fled. He regretted not being for Izuku...

Then, he heard about everything from Dr. Garaki, and that his son was Quirkless, and he dreams to be a hero...

Now, the biggest difference than in canon, he offered Thor's master something he yearned for : A fatter paycheck than everyone, if he went with them. However, if the master wouldn't finish his task, their deal is null and void. Thor wasn't in Japan Yet, as he's actually.. An alien from another planet... Which is four times the size of planet Earth.. Called in his tongue : Jahannam, which means Hell, for very obvious reasons.

The Master, Hanzo Wilson, apart from a mild healing factor, have no abilities, but he's two and a three quarter Centuries old. So, he's a peerless fighter. And he knows of Thor's homeworld. When Thor arrived on earth, the master went to him and told him that he'll be in Japan.. It happened in Bermuda BTW!

So, long story short? Thor met the worst match for him : Stars and Stripes. He asked her for the direction to Japan, and she showed him.. He went there through Mexico and the US, following the sun, drinking from rivers, and going. Then, when he reached the cost, he swam all the way to Japan, and ended up of the Dagobah park...

That happened about five years ago.

Then, he was dying of thirst when Izuku, who had a water bottle, rushed towards him and he was the one who saved his life. Then, the Master arrived, thanked the kid, and went with the giant away. Izuku was ten or nine at most!

Then, they finished their task, which was hunting for some of the hardest Quirks to get, but AFO didn't want any of these for himself, but for his son. He found an abnormally strong Quirk that can control other Quirks, but it required two things : AFO and OFA to be together to power it up. Power Gestalt is a very terrifying Quirk, the more Quirks it's holder have, the more potent and powerful it is, and it can control the output of other Quirks.

So, that project went well, but the master needed one very important theory : How to activate OFA? He actually asked Izuku, who was still a young kid, and surprisingly? His idea worked like a charm! It was the blood of All Might and Nana combined that awakened the Quirk factor...

And AFO copied his own Quirk...

So, this is what it happened. With that new power, AFO was ready to FINALLY show his face to his own son, reconcile with Inko.. Which was..

..The Grandmaster's last advice, as he finally kicked the bucket! Thor went away, hunting whatever he can, and sleep a LOT, if not hybernate.

Then, AFO Vs All Might first fight happened... Which ended up with him looking like an abomination. So, he had to wait.

Then, he had something in his mind, what if Nana and Inko are related? He have the blood of each... Had the Doctor perform a DNA test, and it matched enough to make him realize that Inko and Nana... Are related indeed on the mother side of Inko.

Anyways, the real shoc had but begun!

Also, the Dr. Found a revlutionary way to perform a Quirk compatibility test.. He proposed his theory, but the Goverment and Commission both refused. Of course they would. However, they didn't care, since their Quirk transplant method wouldn't benefit from it. A project undisclosed to the public.

The Dr. and AFO tried a few compatibility tests, and they perfected it, since the old symbol of evil, for all his faults, didn't want to rob his son from his dream, consequences be damned.

However, All Might was faster. He was very close to give up, but... By sheer dumb luck, Izuku failed at Aizawa's test... He got expelled from the hero course, and the rest was history. All that effort to get the most broken collection of Quirks, some were useful, some were complimentary for Izuku's personality, would be put to fruition.

The Grandmaster have one last debt to AFO, a debt he intended to fullfill. So, he had Giran contact Tomura, and it was Toga Himiko's job interview : To join them, and get the help and blood she wants, she have to help in Izuku's kidnapping, if things went wrong for him.

Also, the old man got the call from his agent, and he decided to just have Thor pay off his debt and start working with Izuku as his bodyguard. Who's better than the world's strongest creature on both Earth (which is the original planet of his races) and Jehennam?

However, he needed to kidnap his own son to help him out. But the Doctor told them of the time it would take for Izuku's body to adapt. Thor realized that the kid won't have that much time, so, before transplanting the Quirk and supress it at the same time, he added something to the mix : Magic, which is the sacred treasure of his homeworld. But it required him to be pure of heart and possess something known as the Primordial Spark.

And Izuku checked both, as seen in chapter one.

Here's the entire backstory of this fic. While an alien invasion that turns them to the good side would be a great idea, or Bakugo's death at the Sludge villain's hand... Were the Omega and Delta versions, I got this Beta one, which hopefully will be the Alpha version.

Now, about the hellish training, the entire magic, and everything else, would be explained after the next two to three chapters. I finished the first, now for the second and probably third one..

Anyways, the Q&A is OPEN for everyone. Please, do review? It really does help us a LOT more than you think.
