When Doctor Natalia Robnik, the mahogany colored haired, blue eyed, 185 cm-s tall Villainess, who could pass as Eggman's twin even though she was half times lighter than him, got a call from a man, she didn't expect to her father's friend: All For One talking to her. And the Symbol of Evil had asked something from her.
This scene was a day after the Sport Festival.
"Let me get this straight. You want me to build a robot or an android specifically to kill a First Yearer student from U.A., are you sure about this?" recounted the woman the man's request.
"The target is Midoriya Izuku, heir of All Might's power. He has a great strength and everything to be the next Symbol of Peace." retorted AFO.
"Sure, more like the future Symbol of Hope to me. Plus he is just a teenager who has problems to wield the powerful Quirk of his." argued the lady.
"Who already destroyed a Zero Pointer in U.A. and could keep up with Todoroki Shoto, Endeavor's favorite son." countered the older Villain.
"I am a support Villain, sure I can make something, but don't expect me to make a robot to deal with the target that easily. Let alone that working at the first time. Good Hero Killers are extremely hard to make, and the boy is in All Might's level of power if not stronger. This will be a challenge. I'll send the finished robot and if they lose, I retrieve them to process the gathered data and make a better replacement." agreed the woman.
"I wonder how much robot you'll have to make." mused All For One.
"Who knows Sensei." replied Robnik and her call ended.
.
When Izuku Midoriya went for his internship with Gran Torino, he didn't notice a bigger than average Dragonfly flying over his head. Of course, in the world of Quirks, animals could have one too. However, this was a robot which made some analysis and scanning on the boy without anyone's notice.
At the time as the three Nomu attacked in Hosu and Izuku rushed to save his classmate, Tenya Ida, he didn't expect to see the Hero Killer: Stain in the wall in the opposite of Native and his friend on the ground, nor a green robot with enlarged arms. What?
"Err. Who are you or what are you?" asked the greenette from the humanoid machine, the latter's previous blue visor turned red. 'Uh oh.' noted the teen. And the robot would tackle him if he didn't leap into the air.
"Ida-kun! What is this?" asked Midoriya from Tenya.
"I don't know, just showed up and punched out Stain." replied the similarly confused Ida.
"Would you not try to kill yourself at the next time we meet with Villains? Your brother must be disappointed at you." exclaimed the greenette as the machine stood up. Using the initiative, Izuku rushed the bot in Full Cowl 5% and threw a punch at their head. But the unknown humanoid caught the move and replied with their own. A mighty blow has been avoided narrowly by the OFA's owner.
'What the hell! This thing's punch is as strong if not a bit weaker or stronger than mine at 100%! Unbelievable.' screamed mentally the teen and resorted to a threshold move.
"Hey robot! Take this! Daytona Smash!" yelled the greenette and landed a mighty uppercut on the machine by using 100% in Full Cowl at the time of landing the punch at the target's torso, this sent the bot flying and the boy didn't busted up his hand that bad, at least he could use it.
Unknowingly to the Heroes, a garbage truck disguised vehicle used for analysis and research recovered the robot. Robnik was enlightened by the results.
"Next one needs overall augmented strength, some shock absorbers and several improvements in the system, plus a better design. I shouldn't forget to work on the AI too, this one was a surprisingly heroic machine until it met with the target." exclaimed the woman.
.
Preparing for the first semester's exam Izuku Midoriya trained at the currently empty Takoba beach with Momo Yaoyorozu under their homeroom teacher's supervision.
"So, you met with a robot with your punching strength. Interesting coincidence." noted the girl as the boy recounted the encounter to her, Aizawa was curious too about that.
"Yes, it was weird. The robot knocked Stain into the wall, and it attacked me when it saw me. Hopefully no one plan to kill me with a robot." said the greenette.
"Who would waste their resources for that?" asked Shota Aizawa from his problem child.
"I don't know. Killer robots are not the League of Villains' MO." replied Izuku.
"We should be cautious." warned the tall girl her classmate.
"I am. Plus I have been training harder than before to get better with my Quirk." told her the viridian teen.
Suddenly from the nowhere a humanoid figure leaped between the spar starting students. It looked like a robotic Deku with in a total black costume!
"I think we can refer on this fellow as a male." commented the girl as their teacher leaped into the fray, only to be blinded by a flash from the machine's eyes.
"Damn it." cursed the man.
"What do you want?" asked Yaoyorozu from the newcomer.
"I came to destroy my target." replied the robot and attacked the boy with a Daytona Smash, luckily the target dodged.
"How much Super Moves of mine do you know?" interrogated the worried teen.
"Daytona Smash, Detroit Smash and Delaware Smash." replied the robot.
"Who did send you?" continued Momo the hopeful interrogation.
"Classified." answered the machine matter to factly.
"You better joking." exclaimed Aizawa.
"Humor is not the part of my programming." told him the robotic copy.
"If you aim to kill me and my friend is killed or hurt accidently by you in process, what will you do? Will you continue your directive to kill me or try to help her if she is hurt?" asked Izuku his double.
"Error! Logic bomb detected!" exclaimed suddenly the machine and he ran leaped into the sea to self-destruct.
"Did you just defeated it with a logic bomb?" asked Eraser his male student.
"I thought his AI is might be based on mine a bit, ergo the person who made it didn't think this out right. If there is a next one, this trick is possibly useless against him." told him the greenette.
"This was a swift and smart idea." complimented Yaoyorozu her friend.
"Should we continue our Quirkless spar or should we do it after giving our testimony to the police?" turned Izuku to their teacher, who just sighed.
In the sea a small submarine recovered the remnants of the robot. Inside was the crew consisting Robnik and a duplicate of the first machine.
"Second model failed by a logic bomb. I need more work and a better AI." noted the woman.
.
At I-Island after defeating Wolfram's gang, Izuku and his friends plus Melissa Shield saw a blue blur leaping in front of them on a beach part of the island.
Further examining the newcomer with their eyes, they realized a robot look like Midoriya. Yaoyorozu's and Midoriya's eyes widened in shock when they figured out the dark blue copy of the greenette boy is look like the previous one which with they encountered.
"Oh come on." rolled Izuku his eyes if he was bored.
"I'm going to blew you up Robo-Deku!" yelled Bakugo as he attacked the robot, but the latter dodged his attack.
"Uhm. Midoriya-kun? What's going on?" asked Kirishima from his classmate.
"His father building robots to test his son's capabilities indirectly." declared Todoroki.
"Is that okay?" asked Melissa from Yaoyorozu and Jiro also looked questioningly at the tall classmate of hers.
"No he isn't testing me!" snapped Izuku at the dual Quirked boy as Bakugo wrestled with the robot.
"Someone tries to take out our classmate permanently with robotic duplicates. They seem to be better by each try." revealed Momo to the others.
"That's not explaining that how did this one come here." said Melissa.
"Hey! How did you come here?" asked Midoriya from the robot, which currently threw Bakugo to the ground like Izuku did at the battle trial.
"By flying. I can fly." replied the machine and the greenette spotted the engine like exhausts on the blue aggressor's shoulders and legs.
"Is that enough?" snarked Jiro at Melissa Shield.
"Did he just asked the robot?" asked Kirishima from the girls surprisedly.
"Yes, he did. The previous one revealed to us why these are coming after Midoriya-kun. He theorized that the green one had a similar role too." replied the Yaoyorozu.
"Leave Deku-kun alone!" yelled Uraraka as she lounged at the robot, but the latter smoothly countered that by throwing the unfortunate Bakugo at her.
"My directive is simple. Kill my target." exclaimed the machine.
"You're better than your predecessor. Did your creator improved on your AI too?" asked him Izuku.
"I have the analytic mind of yours, the knowledge of your Super Moves and I can learn extra tricks you would use against your researched opponents as well adapting to a new scenario by analyzing without the need of improving my capabilities." replied the robot then he did something unexpected, he swore. "Shit!"
"I agree!" attacked Izuku his doppelganger with Full Cowl 5%, the copy matched him, their held themselves in a brawler lock.
"Izuku! Catch!" shouted Melissa as she threw an object to the Hero Course student, he caught it when he pushed the robot away and took on the object, which was a spare Full Gauntlet.
"Thank you, Melissa!" replied to her the boy, activated the support item and threw a 30% punch at the blue opponent of his. The suddenly stronger attack caught the latter off-guard and he was pushed five meters away by the force. Following that Izuku rushed to land a 99% Detroit Smash on the intruding machine, after that he gave a metronomic man smashing to it and threw it into the air.
"You have a glaring flaw." said Midoriya before he leaped after the droid. In the air he started to yell his words. "YOU CAN LEARN BUT YOU CAN'T PHYSICALLY ADAPT! YOU CAN WITHSTAND MY NEAR FULL POWER FOR ONE PUNCH OR CAN YOU FOR ONLY A WHILE? LET'S TEST IT!" shouted the teen and he pummeled the robot with hundred punches, nearly tearing it apart and threw out of the island with a mighty Oklahoma Smash.
When he landed on the ground, everyone thought they won, unknown to them Doctor Robnik was ready and with her submarine she recovered the nearly scrapped failed to kill Izuku Midoriya robot of hers.
"Machines are machines, they can't evolve or endure like humans." exclaimed Izuku.
"But they can be much more easily made." finished Robnik the sentence which she started in unison with the boy unintentionally. She knew the success is hard to earn, but she was closing to the end of All Might's heir.
