Will

Prologue

Without a doubt, this man is the absolute strongest there is. Even when facing the 7 greatest heroes of this generation, he isn't even breaking a sweat.

They go by the name of "The Color Changers." They consist of Fudo Todoroki; Quirk: Fireballs - he can create and throw fireballs that are always the same size, but they can vary in heat up to 200 degrees Celsius, Kawa Izumi; Quirk: Water Creation - she can create water out of nothing and can change the pressure up to around what it would feel like at the bottom of the Mariana Trench, Raidon Kaminari; Quirk: Lightning Summon - he can summon lightning anywhere around him in a 15m range, Nikko Hassakai; Quirk: Flash Forward - she can speed the movement of something that is moving at a known target up to almost instantaneously, Michiko Shuzenji; Quirk: Energy Conversion - she can convert her energy into either curing a wound or providing stronger power for another's quirk, Nyoko Uraraka; Quirk: Zero Gravity - she can remove the effect of gravity on any inanimate object, and Inu Midoriya; Quirk: Telekinesis - he can control the movements of any inanimate object within a 15m range and the weight of the object affects its kickback and his control on it.

So somehow even with these quirks that were considered the greatest of their time, The Color Changers were on the back foot in this battle. All For One, as most people called him, has already sent tendrils through the shoulder of Raidon who was keeping All For One trapped in a lightning barrier. And just now he sent a powerful gust of compressed air right at Michiko's chest to prevent her from providing energy to an ever growing tired Fudo and Kawa. They all knew there was no way they were taking down this menace, at least not with the quirks of this generation, so there was only one option.

"Everyone, this is an Order 0, you know what to do" shouted Inu, the co-leader of the group.

When the rest of the Color Changers hear this, they start to feel a lot more shaken at what is coming next because they know that what's about to happen next is going to be HUGE!

And they don't disappoint.

Fudo and Kawa create as many fire and water balls as they could muster, Nyoko removes their gravity, and Inu holds them together with his telekinesis. Meanwhile, Raidon summons lighting to prevent All For One from interfering, but it looks more like he is enjoying watching them try. Michiko and Nikko try to gather as much energy as possible because both of their next moves will require a lot out of them.

"READY?" Nyoko, their other co-leader, practically yells.

"AS READY AS I'LL EVER BE" Nikko yells back while Michiko silently nods next to her, not wanting to waste even a word of energy.

"NOW" Raidon screams after getting All For One in the perfect position.

Inu sends the giant flaming ball of obsidian at All For One, but before he could get a good grasp at what was coming for him, it was already in his face due to Nikko's quirk. While the impact was huge and any normal person would definitely be dead, this wasn't any normal person, so Order 0 wasn't to kill All For One, it was to do as much damage as possible. And by sheer luck, they succeeded.

That was Step One Complete.

Now for the hard part.

Everyone who can move starts running in the direction of Michiko and she starts glowing white. The white light continues to grow until it eventually surrounds all of The Color Changers.

They all focus their will on becoming something strong enough to beat All For One, and with a mix of Michiko's quirk, their collective will, and a pinch of luck, they transform their quirks and consciousnesses into one. There was just one catch.

Themselves

The Color Changers sacrificed themselves to create a quirk strong enough to beat All For One. A quirk that will be bestowed to one of their family members in the far future. A quirk that will show itself when we need it the most.

And we definitely need them now.
