Cross Marks

The cross Marks are individuals with special powers who were abandonned by eden. Eden believed them to be valueless. These people are marked by a dark X on them or a bar code. In chapter 158 when going through the secret entrance to Eden, Ogami aand his companions meet a bunch of them. Yuki explains about their origins. Yuki also reveals that he was once one as they try to attack Ogami and company. Most of them are later killed by Utah. He later explains tha Boldt the bar code means that those people with it are the elites of the cross mark and have a purpose. He then attemps to kill them all until Yuki intervens. With their last bit of power they give it to Yuki.
