Jaycen was born into the Inhuman community of Utolan, but was adopted when he was young into a different Inhuman community in Minnesota by a man named Martin and his wife. The couple rechristened the boy as Jason, and raised him as their own son. However, Martin was caucasian and Jaycen was black, and unbeknownst to Jaycen his adopted parents were members of a community of Inhuman descendants that had very little Inhuman DNA left and had tried to avoid Terrigenesis (the process of an inhuman gaining their powers) for 10,000 years.
After the detonation of the Terrigen Bomb and the arrival of the Terrigen Cloud upon their town, the whole community tried to run away together. Martin had a hard time convincing Jason, recalling the moment when he told him that no matter their blood, he was his dad.
