Mother's first Creation.
Cubix remembered his birth very clearly.
He came into the world as little more than a drone with a self learning AI, designed little more then to be an assistant and helper to his creator. His creator, his mother, was the first thing he saw. She was looking at him with a concern look and a furrowed brow, he remembers flouting up a few inches off the workbench to see if she was alright.
Her smile when he flouted was worth shooting upwards into the roof and bouncing around the room due to faulty anti-grav generators, after being repaired he began to help Inko around the house in small ways but began to talk on more duties as she became pregnant and Hisashi wasn't around to help.
Overtime, he began to grow as new parts were added to help him perform his duties. Going from a blocky drone capable of lifting small objects with tractor beams to a small swarm of machines capable of performing all the duties required of maintaining a home, however being unable to cook without burning something.
When Izuku was born, he helped watching over his new 'Little Brother' as best he could. Whether by, freeing Inko from certain tasks or by monitoring Izuku as he slept and when Inko was preoccupied with other matters.
It wasn't until after a family camping trip in the mountains did he received the upgrades that changed him into what he was now, Izuku had gone off the trail a little to explore with one of Cubix's many drones watching over him. The same drone that alerted the others when Izuku had fallen into a cavern after the ground was damaged by a recent battle with Pro Heroes and Villains.
Thankfully, Izuku was unharmed from his fall. The drone ensured he didn't move too much until his parents arrived, in the meantime he looked around the cavern he had fallen into with the drone with him providing light.
In that cavern were cave paintings of robots of numerous designs and pieces of fossilized medals with gems embedded in them, medals that would crumple into dust if mishandled.
Tests revealed the cavern had remained untouched for millions of years, meaning the cavern was proof of a precursor civilization of a mad scientist had traveled back in time.
And given the existence of time machines, he was inclined to believe the latter.
Hisashi and Inko were willingly to abandon the cavern and it's content, but Izuku wasn't. He was drawn to the medals and the paintings on the cavern walls, and managed to convince his parents to do research into it.
Research that led to the creation of Medabots, his upgrades and their little sisters.
It was the responsibility of the older brother to watch over the little ones after all, so it was natural for he and Izuku to help Brass and Base get settled in, even as Inko and Hisashi went out to discover more of those mysterious sites from around the world by themselves or by sending specialized drones.
Izuku was enraptured by the concept of Medabots and began making his own designs with many specializing for certain tasks, designs that inspired Inko to mass produce Medabots to help better the world.
However, their greatest challenge was finding the money and resources for such a feat.
A number of options were considered for avenues to take, and a large number of other avenues were marked as unacceptable such as use in wars.
In the end, they decided on the plan.
Using DNA from over a dozen people Inko would grow an artificial human with cybernetics in it's brain, it would act as Inko's puppet and present Medabots as helpers and companions. Given the constant need of medical workers having mechanical helpers would be a massive benefit and having Medabots being seen as companions would aid in preventing suicides, though it all hinged on people accepting Medabots were to be friends and comrades and not to replace anyone.
Of course, Izuku was left in the dark with most of the plan. With Cubix making neither Izuku or their little sisters knew about the underhanded deeds they had done.
It took years, with more than a few close calls, but they had done it.
The Medabot Corporation was formed and had grown to be an international sensation, production had to be reworked several times to keep up with demand and the cooperation espionage needed to be stumped before any valuable secrets were leaked.
To be on the safe side, Hisashi became one of the Board of Directors within the company with half of the board being more artificial humans.
Cubix was happy to see everyone else happy, but he was happier about one thing. Walking in public in his full form and not as his main control drone, it was nice going out as a family.
When Izuku changed in his final year of middle school he assured his sisters their brother Izuku was still the same person, though Cubix wouldn't admit it he did have Izuku deep scanned to make sure nothing was controlling him.
Then came the UA Entrance Exam where he broke his right arm and both his legs, Recovery Girl had healed him and had began using Support items to lessen the damage he takes but, then came the USJ Attack and the Stain incident when he was interning at a hero agency.
It was due to these events that Cubix swore to being more supportive to his little brother, which is why he took a sniper position on nearby rooftops to snipe the mysterious men who seemed to have indirectly done something to him. Thankfully, he didn't need to shoot, he just kept watch and notice nothing usual besides the odd number of people and animals being chased by bats.
As they walked home, Cubix had to mediate a conversation between Brass and Base to make sure they didn't try anything after Roxana had gotten under their chassis.
A conversation that lasted their entire walk back, a walk that took them 30 minutes to physically move but had an accelerated conversation making it 2 hours for the three robots.
Sadly, their night was not yet over as Inko's brother Malcom and his wife came to warn them of the information of Irene Venture being alive.
Thankfully, they had plans for this.
Now, it was about figuring out if the clone bodies and liter fluid were needed.
