Baby Binome is an infant one binome living in Mainframe. His mother is a zero binome and his father is a one binome named Jimmy. He is almost always seen holding a toy of Bob. The Baby Binome and his parents were evacuated to the Principal Office as the Medusa Bug was infecting the system. He began to cry as the building turned to stone. After everyone was infected the stone figure of his mother was seen trying to hand the baby to Dot. Bob, being immune to the viral bug, took the baby's infected toy and went to see Hexadecimal in her Lair. He threw the toy at Hex to try and infect her, but she easily stopped it. (The Medusa Bug)
