My Hero Academia: Rise of Ben 10, Book 1.

Komodo Dragon

Tomura Shigaraki tapped his fingers on the table of the old bar rapidly.. 

He was a youth with the look of heavily dry and scratched skin, pale colored hair, and on his face he wore what appeared to be a severed hand that clutched his face like a mask. 

He was the type of villain who had become famous almost overnight. As the youth who was high up in the League of Villains, and had audaciously invaded the school at one point in an attempt to kill All Might as well as having at one point been associated with Stain, it was safe he was on Japan's top most Wanted List. 

What was also dangerous was how child-like he could be, but also how he was slowly maturing into a villain that could sow chaos. 

Vilgax could see that. He had to hand it to All For One, he had been cultivating something with impressive potential. Not only was Tomura easily moldable, but he had hidden talent. Vilgax would have to figure out some way keep him around. With such a moldable clay hidden in this strange human, he would simply need to manipulate Tomura into believing that Vilgax had been All For One from the beginning.

Oh well, no use rushing..

"Master." Tomura muttered as the orange lighting of the bar flickered, turning to look at the TV screen that displayed Vilgax in his All For One disguise.  "I don't see why we need to take in new associates so early.. I already have the Vanguard Action Squad preparing the plan to mobilize on the summer training camp.. at this point New blood would-.. I don't know.. "

"Patience Tomura." said 'All For One'. "Haste will only make waste. This is a subordinate I've cultivated purely for your success."

"Ggghh.." Tomura began scratching his face in a rather disturbing way. "If you say so Master, but I can handle this myself, all for you!"

"Of course. I know you can, but I also do this purely for you." said 'All For One.' "If you fail, we merely need try again, and again and again, and I will provide you all the necessary resources for achieving what you want."

"What I want.." murmured Tomura. 

Vilgax had spent hours watching old tapes of All For One's conversations and dealings with Tomura Shigaraki, he had perfectly mastered imitating All For One's personality. Every one of his mannerisms, even managing to imitate the crime lord's personality. 

This was good. The League of Villains was the perfect means to use the Underworld to gather information on the Omnitrix and One For All.  It would just take patience. Yes, underestimating humans here due to past prejudices would not do, these so called Quirks already proved they had the potential to be as powerful as the other denizens of the galaxy. 

And whoever held the Omnitrix would be powerful indeed.  And he was slowly learning his own power at the tutelage of these so called heroes. Shigaraki would have to be utilized if he was to obtain the Omnitrix as his own without breaking it down a useless mental state.

The door opened, and 'All For One' was shaken from his thoughts. "Ahhh.. he is here."

A Tall figure in a black tuxedo entered the room. He wore a silvery metal helmet with no facial features over his head. 

He was accompanied by other men and women wearing black suits, a total of five individuals.  They all wore fedoras covering their faces. One of them in particular looked extremely massive.. his suit barely able to fit his massive body. 

"Overlord.." said 'All For One'. "A pleasure for you to join us."

"Where is Kurogiri?" said the helmeted man in a disguised electronic voice. "I was under the impression that he would be here, he's the one who invited us."
