After watching mutants hunted for years, Magneto declared war on humanity and was joined by Charles Xavier when his students were killed in the destruction of the X-Mansion In order to quell the mutants, S.H.I.E.L.D. kidnapped the family of Reed Richards and forced him to create a virus that would attack mutants. When Reed succeeded, he was horrified by the deaths caused by his virus and escaped to Mars with his family and four infant, mutant test tube babies.
Reed worked with the children as they grew and took the names Frodo, Lys, Tarf, and Trago. He trained them as their mutant powers manifested to become the first soldiers in a new war on Earth. [1]
