O-Part: Justice (5 rings)

Former commander of the Stea Republic SS Rank O-Part ship Shin (God). Cross lived alone with his younger sister, Lilly, after their parents left when they were younger. The two went to church often to pray for their parents' return. One day, Jio came to the village where Cross lived. The Satan inside Jio noticed Cross was the No. 1 Angel - Metatron, the only being he recognized as having the power to defeat him. So he erased the existence of Cross's village, including Lilly, who was actually a copy of the No. 10 Angel, and the Solomon's Key that would awaken Cross's angel form. Cross witnessed his village's destruction, and realized that it was Satan who killed Lilly. After his village was destroyed, Cross was taken by the Stea Republic onto Shin and promptly found out he was an O.P.T. He is an extremely powerful O.P.T., and so became the commander of Shin. He continued to search for Satan, and Satan's plan was to absorb Cross's hatred and enormous power after it had matured enough. However, that plan was thwarted by Ruby and her jade pendant, the real Solomon's Key, who awakened Metatron in place of Lilly and changed the hatred in Cross's heart to purity. His O-Part is Justice (C rank), which consists of five rings.

As of the beginning of the time-skip he was traveling with the rest of the Ophan Crew helping them look for Jio. As with most of the other characters after the time skip his appearances have changed, he has kept his short hair but has taken a very feminine look with his clothing and facial features outside of battle even being mistaken for a female by enemies.

He has recently re-met up with the famous hacker Ponzu who has taken Lilith's recipe nuclei into herself and brain washed him using it. Ponzu relieved that she has been in love with him but he was so obsessed with Satan that he left without even leaving a note and without her confessing her feelings. Cross after coming to his sense removed the nuclei with Metatron and seems to have a touching moment with Ponzu. He has been sucked into the completed Shin, while inside shin to save the world with the help of Jio, Ruby, Zero and Jack himself they warped shin away from earth just as night fell disappearing into the void of space.
