Izuku and Hansuke met up with the other pro-heroes who were not present during the attack on the festival. Everyone at their healthiest and strongest.
Many of them included Toru Hagakure, Mina Ashido, Mezo Shoji, Tenya Iida, Fumikage Tokoyami, Eijiro Kirishima, Hanta Sero, Rikido Sato, Yuga Aoyama, Itsuka Kendo, Inasa Yoarashi, Mashirao Ojiro, Camie Utsushimi, Tsetsutsetsu Tsetsutsetsu, and some older and more experienced pro-heroes, although not many.
Although some of them didn't have the Quirks of fighters, every single one of them was a fierce warrior.
They gathered together in a circle outside of the city near a dam. Within their circle and around were dozens of police officers as well.
"From what we know, Nucleon is taking orders from a multi-Quirk villain who calls himself Promethys, the giver of all Quirks." Detective Tsukauchi announced to the large team of heroes and police.
"They've hired an assassin villain known as Inflictor to create a disease that prevents full Quirk usage, which he then unleashed on the pathetically guarded hero festival." He continued.
"We are to assume that all three are here now at Ogouchi Dam. Scanners in the city picked up, moments after they disappeared, a power surge. They're trying to use the dam's power for something."
He then pointed to the heroes around him. "The Pro-Heroes will be lead by Ground Zero and Shoto." He then gestured to Katsuki and Shoto, who both nodded back.
"The mission is to find out what they're doing here, and to put a stop to it." Detective Tsukauchi said. "We have no idea what Promethys is capable of aside from previous encounters with Deku and Shoto. But we also know that he is the villain responsible for the prison break, and the deaths of dozens of guards and the warden himself."
"Permission to add something, sir." Izuku spoke out.
"Go ahead, Deku." The detective addressed him.
"When I fought with him... I felt power I hadn't before in years... He reminded me of the days of All For One... His determination, his goals, his might...his power... Be advised, if he makes eye contact with you, he can access your Quirk for himself, along with the Quirks of your ancestors." Izuku explained.
"Does this mean he's got your Quirk?" Tenya spoke up in concern.
"N-No, I was able to use Fire Sight to block him." Izuku said quickly using the lie he forced himself to prepare for this exact question. "I think he knows what my Quirk is, and my parents'. But he doesn't have mine."
"That's a huge relief." Tsukauchi sighed happily.
Izuku nodded with a nervous smile.
"Where on the dam are they located?" Shoto asked.
"Surveillance shows Inflictor working on something on the top of the dam connected to the cell tower. Nucleon is standing guard at the much wider access entrance to the facility. And no signs of Promethys but he could be using some sort of Quirk to hide from our spying tech." Tsukauchi said.
"So let's overpower the one guard villain and charge our way through! Our numbers are perfect to take on anything!" Katsuki shouted.
"We need to see what Inflictor is doing. It could be a bomb. As soon as he hears we took down Nucleon, he could set it off. If it jeopardizes the dam, our lives, or the lives of anyone living in the wake of the dam, it's not worth the risk." Shoto said.
"I'll volunteer to sneak past Nucleon and see what Inflictor is up to." Toru spoke out, waving her glove around. She had recently upgraded her suit and gloves to camouflage to any surroundings, refracting off of her invisibility.
"Keep in touch using the earpieces." Tsukauchi reminded. "We need to keep everything reported. And we need to find Promethys."
"Roger that!" Toru replied confidently.
"Be careful." Mina requested her friend.
Toru gave her a silent thumbs up before cloaking her entire body, suit, gloves and all, and pressing forward beyond the base camp.
Izuku looked on past the trees. A short distance from their position, Nucleon was out on the maintenance driveway leading to the large sealed door to the dam, sitting down.
He seemed simultaneously riled up for a fight, yet peacefully meditating.
Toru had managed to tiptoe up to his location and with her experience with stealth, slipped past his suspicions with ease.
Before she could radio to the others that the easiest way in for her was shut, and there was no way she could open it and run inside without Nucleon hearing it, Hanta launched his tape out from a nearby bush and wrapped up Nucleon at his torso.
Using the ensuing commotion for cover, she opened the maintenance door and shut it behind.
"I'm inside! Anyone engaging Nucleon, be careful!" She whispered.
Then she proceeded forward inside the concrete facility down a narrow corridor that lead into an open chamber where turbines converted the dam's water into energy for the machines below. Past that was a set of stairs that lead to a platform on the roof.
As she snuck out to the roof, she could see Inflictor tapping a series of numbers into a machine hooked up to the cell tower. On the machine were several canisters with hazard symbols on them. Bingo.
It was without a doubt what they were here for. As she approached closer, she noticed a vial sticking out of a pouch on Inflictor's trench coat.
And out of the corner of her eye, she nearly made a noise seeing all three meters of Promethys step forward seemingly out of nowhere.
"Those 'heroes' and authorities have arrived. They plan to storm us and stop the machine here." Promethys reported.
"Well, all I have left to do it type in the sequence that activates the release. Once I do, the machine will launch the disease out into the atmosphere and global outbreak will begin. It's been enhanced to become airborne without the usage of gas." Inflictor explained.
"I expected nothing better." Promethys nodded. "Now type it."
Toru backed behind the corner at the top of the staircase. "Guys... It's a machine to unleash the virus into the atmosphere... On the roof... And there's no time to stop it. I have to engage."
"Toru, listen to me! Do not engage! Wait for us! Shoto's almost frozen Nucleon solid!" Mashirao shouted in the radio.
"I'm sorry..." She whispered and silenced her earpiece. "It's what a real hero would do..."
With the stealth and speed of a cat, she rushed forward, her sound-cancelling boots rushed her up to the machine where the villains were standing, and Inflictor had his hands on the keypad.
With a swift motion, she kicked the keypad from his prosthetic fingertips, and was immediately seized.
Promethys, with heightened senses, grabbed Toru by her neck and picked her up while Inflictor scrambled to grasp the keypad again.
"You foolish girl..." Promethys snarled.
His grip on her neck tightened as she struggled for breath, disconnecting sensors in her suit and made it visible again.
"You will be the first of many to die today..."
