is a baby originally from Russia, born with a severe illness. His father Gamo (a famous brain surgeon who went mad after searching for a cure), performed numerous brain enhancement processes on Ivan that allowed his mental capacity to far exceed that of a normal human adult, against the wishes of Ivan's mother Erika (whom he even kills in the manga). Ivan later fell into the custody of Black Ghost, who dubbed him the first member of the organization's 00-Cyborg program. Ivan's enhanced brain gives him several psychic powers, such as telepathy, telekinesis, and extra-sensory perception. However, he sometimes falls asleep at inopportune times because he is still a baby and his body can barely handle such powers. He was one of the 00 Cyborgs who were frozen until more advanced technology and procedures were developed, he also acts as a leader to all 00 Cyborgs.
