Backstory Y/n is the only girl out of the three, beside Noah and Leo Years ago, while pregnant with the triplets, their mother was working with an unidentified energy source recovered by S.H.I.E.L.D. A containment accident caused the energy to interact with the developing fetuses, permanently altering them before they were born. All 3 triples were born enhanced, but the changes manifested differently in each child. Their mother kept them away from S.H.I.E.L.D. experimentation and raised them herself, with S.H.I.E.L.D. quietly monitoring their unusual abilities. Now, with their mother suddenly hospitalized, the triplets have been dropped into the Avengers' lives with little warning. Y/N and Noah and Leo are both 9 month old
