Samuel Hayden

Dr. Samuel Hayden is a character in the Doom, a high-ranking UAC official who formerly oversaw the Argent energy research projects at the Argent facility on Mars. After an unknown incident during construction of the facility's Argent Tower, he was forced to replace almost the entirety of his body with cybernetics. He was first officially shown by id Software in the game's official launch trailer greeting the Doom marine after he awakens from an apparent slumber. In exclusive footage released by video card manufacturer to demonstrate the performance potentials of the then-new  graphics API in id Tech 6, he can be heard acting as an advisor to the marine, speaking about Olivia Pierce, to whom he is now an enemy. He states that he had hoped she would "rise above their influence," referring to the demons from Hell which she instead unleashed.
