From my Grimjack adaptation. The murderous A.I known as Kalibos. Kalibos was a sentient robot created by the Free Marines several centuries before Gaunt's time. Imbued with the Marines' love of freedom, Kalibos took the concept to its absurdly logical extreme of nihilism. Seeing demons as the ultimate expression of his brand of freedom, Kalibos allied himself with Hell during the Demon Wars, performing operations in parts of the city where demons could not function. Kalibos always skinned one of his victims and wore his or her skin as an affectation.
Artists note: In my design , I envisioned him as a combination of a young Ian Holm and Sam Worthington, both of which played human-like robots in sci-fi movies.
