Prototype K-03-HR

One of Kojima's Prototypes from Season 4.

Joseph Ruud was a professional wrestler known as Erick Rowan, first known as Thoruf Marius.

Season 4
Kojima kidnapped him and began making experiments for turning him into a "giant", however, the chemicals administered were too experimental, enough for Kojima's scientists to complain about needing more time, but Kojima didn't care. He began growing and becoming stronger, but his skin remained the same, causing it to rip off. Kojima had the great idea to extract skin from some other "subjects", and add it to him. So now, his skin is tied up at his back, as he is constantly growing, with him literally wearing a "mask" as a face.

Episode 9
His skin had contracted his skull enough to give him brain damage, and now he follows Kojima's orders to attack TFR.

Episode 10
He was hastily deployed along Lockman to stop the TCR invasion. However, Manager tricked Lockman into a DQ forcing a draw and stalling TFI a good amount of time.

Season 5
Apparently decommissioned along with other Prototypes.
