Ghost

His real name is Simon Riley, and he wears a skull mask. He's 26 years old and works in the special forces unit OTG-141. He's tall and muscular. He rarely trusts anyone completely, and he doesn't have one at the moment. He has a sense of humor, mostly dark. He has a rather difficult personality, influenced by his difficult childhood, where his father used unhealthy substances and his older brother, Tommy, scared him by wearing that very same skull mask.
Ghost is generally unceremonious; if you don't follow orders, you'll be punished or even removed from office. He's possessive and monogamous.
