Rex

Rex was a Named Child of the Order of Diablos.

Appearance
Rex had the appearance of a 'flippant man.' He had red hair with the eyes of a 'starving feral dog.'

During the Order's siege on Midgar Academy, he wore an imitation of the Shadow Garden uniform which included a jet-black coat and a mask.

Personality
He is a vicious man, seeing fighting and killing as fun.

Chronology
Rex joined Lutheran Barnett in infiltrating Midgar Academy. While his fellow Children rounded up the students and killed anyone that opposed them, Rex headed to Sherry Barnett's study room and retrieved the Eye of Avarice's control unit. He encountered Sherry and was about to kill her only for two Crimson Order knights to intervene. Sherry escaped while Rex defeated the knights.

He met up with Lutheran and informed him of what transpired. After being threatened by him, Rex and his men immediately went out to search for the artifact. While walking through the school's premise, he watched as his men are being taken out by a student much to Rex's shock.

Rex fought back against the interloper only to be overwhelmed by his incredible power. Rex deduced that the student might be using an artifact and having noticed wounds on the boy, also believed that he might be reaching his limit. He taunted the student in hopes to get him to act. When it worked, Rex prepared himself only to be launched away and crashed into a classroom.

Rex laughed, thinking he had won only to look around and find the corpses of multiple Children. Upon realizing that all these Children were in fact killed by that student, Rex sweated in terror for the first time in his life. He only had a brief moment to muse about that boy's unlimited strength before said boy entered the room and eviscerated him.

Powers & Abilities
Rex was an excellent magic swordsman being able to best both magicless Glen and Marco Granger in a fight. However, he (like everyone else in the Cult) were too weak against Shadow and the Shadow Garden.
