My Amazon Rider Academia.

Narrator: a long time ago there's Humans who have Super Powers called Quirks

and some of them who don't have Quirks are called Quirkless and are treated like out casts

But there's a new third Option was born this Third Option are Man-Eating Monsters called Amazons The Amazons (アマゾンズ, Amazonzu)[1][2] are humanoid organisms created by Nozama Pharmacy from an artificial cell called the Amazon Cell (アマゾン細胞, Amazon Saibō). They require a large amount of protein to sustain themselves and have a strong instinctual hunger, leading to them hunting humans or even cannibalizing other Amazons

Two years ago, there was an accident in Nozama Pharmacy's laboratory and about 4,000 human-eating Amazons were unleashed in the city. To cover this accident, the Nozama Pharmacy formed a team of Amazon hunters, under the front of Nozama Peston Service, to hunt down the escaped Amazons.

These are the first created Amazons, and there are 4000 of them in total.

These homunculi are entirely capable of blending into human society and feeding on a normal diet if their human-eating instincts are suppressed by specialized drugs. However, once the cells fully awakens, their instinct to consume humans take over and they become human-eating monsters. To make things worse, the process is entirely irreversible, resulting in killing them being the only way to avoid further casualties.

They are equipped with Amazons Registers, which act as the supplier for specialized drugs and double as a marker, each of the registers have a unique "secret code" for the Nozama Peston Service to eliminate them. While it was initially suggested that their human-eating urge can only be suppressed by specialized drugs, it is later proven that this urge can be permanently suppressed through severe traumatic experiences, as most of the surviving Amazons five years later after Operation Tlaloc still have their Amazon Registers in blue, and most are incapable of directly hurting humans unprovoked. They are even incapable of bringing themselves to eat humans, despite desiring human flesh.

The Amazons Register (アマゾンズレジスター, Amazonzu Rejisutā), also called Amazons Bangle (アマゾンズバングル, Amazonzu Banguru) is an armlet like item produced by Nozama Pharmacy. They are implanted in every Amazons' left arms. As a control device, its function is to inject drugs regularly into the Amazons' bodies to suppress the awakening of the Amazons and the Amazon Cell.

The drugs in the Amazons Register last for only two years maximum. After the drugs run out and the user feels the urge to eat humans surge, its blue "eyes" will turn red and it then acts as a tracking device to alert the higher-ups of the Nozama Pharmacy and the Nozama Peston Service Extermination Team. Without the drugs to keep the Amazon Cells in check, the Amazons will awaken and, overpowered by their instincts to consume human protein, turn into human-eating monsters.

It is impossible to regain control of the Amazon Cells of awakened Amazons again by using the Amazons Register or the drugs. These awakened Amazons will have to be killed to avoid further casualties.

Interestingly, despite previous claims regarding the drugs they hold, five years after Operation Tlaloc sees that many surviving Amazons still have their registers with blue "eyes" instead of red. Furthermore, instead of turning into human-eating monsters, most of these Amazons are unable to even bring themselves to eat humans due to traumatic experiences, suggesting that severe psychological trauma might prove far better suppressants than said drugs.

And now the pro Heros and All Might himself must hunt down All Amazons before their Cells are fully Awaken and Kill innocent Humans

And there's one Boy Named Izuku Midoriya the Quirkless but not Powerless boy who discovered he was born with Amazon Cells and has Awaken and he's a Hybrid between the two and that's we're his Story Begins.
