His Alpha's, Their Omega

Set up

This book is a mix of My hero academia characters & the omegaverse. Omegaverse can vary and mine is a bit different.

*****************************************************************************************

There are males & females. They can be Alpha, Beta or Omega.

Alpha's that make up about 20% of the population and are usually born to high society people (other Alphas) and have powerful quirks.

Beta's make up 70% of the population and have simple quirks.

Omega's make up about 10% of the population. They don't have quirks but have a 50% chance of giving birth to a child with a quirk.

Most omegas are born to Beta/Beta or Alpha/Beta parents. In extremely rare cases an Omega will be born to Alpha/Alpha parents.

*******************************************************************************************

Mate marks:

A mark will appear on your skin once your mate turns 18.

Example: if you're 16 but your mate is 18 you will get a mark on your skin but a mark won't appear on them until you are 18

Alpha's: mate mark will appear on their right forearm

Beta's: Mate mark will appear on their left forearm

Omega's: their mate marks are hidden. Their marks are on their hips/lower abdomen area.

Mate marks will have some relevance to your mates quirk.

If your mate in an omega the mark will be a flower that is the same color as their hair/eyes since they a quirkless

Each mark is unique to the person. No two marks are the same

******************************************************************************************

Scents:

Only your mate can smell your scent once you turn 18 even if they aren't of age yet

*******************************************************************************************

Everyone has 1 mate mark. It's almost unheard of anyone having more than one mark. The last person to be born with multiple marks was killed 50 years ago. Reason: they were an omega.

If an omega has multiple mate marks:

- the chance they have a child with a quirk is 100%

- their child will have a quirk

- they themselves are able to use the quirk of their mates once they are bonded

If a Beta has multiple marks, nothing special happens to them other than basically having a sleeve of makes. If an alpha has multiple marks they can use the quirk of their mates as well
