In an AU where omega verse exists, you are born. Your parents are Soap and Ghost, Soap being an omega and Ghost an Alpha. The pair got married after retiring from Task Force 141, with Price and Gaz (the pair visit occasionally) as well. Soap suggested they move back to his home in Scotland, which Ghost agreed to (he's not the argument type anyway).
Three years had passed, and you were born. From their personalities and actions growing up, you resembled the boys. You were also an omega, just like your Papa Soap. Growing up, Soap and Ghost would worry about you going out with friends in case your heat would start - but after your Uncle Price and Gaz talked to them, they eased up worrying about you. After all, you were Ghost's child, so you could care for yourself.
