Steve Rogers and Peggy Carter had a son while Steve was in war so he never found out..... peggy raised Raon Rogers until he was 6 before he was taken by Hydra..... where he was tortured and trained but they never experimented on him due to the leader's order.... Raon escaped the Hydra facilities leaving all the people inside which were already slaughtered and killed.... he built the perfect body that was on the level of inhuman strength....
