As a member of Astro Boy<\/a>‘s family, like his little sister Uran<\/a>, Cobolt’s name is reflective of the atomic age – in this case the radioactive isotope Cobolt-60, which was famously used at Columbia University in the 1950s to establish parity violation in radioactive beta decay.<\/p>\n Astro Boy<\/a>‘s older brother shares a strong\u00a0family resemblance with his more famous sibling. \u00a0However, while he also has the famous “double triangle” hair style, his face is longer and more oval-shaped than Astro’s. \u00a0That makes them easy to tell apart.<\/p>\n An inferior copy, created by Dr. Ochanomizu<\/a> as a temporary replacement for Astro Boy<\/a>, Cobalt has abilities comparable to those of his brother. \u00a0However he lacks Astro<\/a>‘s intelligence and common sense and is often clumsy, gullible, and accident-prone as a result. \u00a0Although he often causes problems for the entire family, he remains extremely kind-hearted and loyal – characteristics which help Astro<\/a>\u00a0out of trouble from time to time.<\/p>\n Primarily a member of the supporting cast in Astro Boy<\/em> (1952-68)<\/a>, Cobalt\u00a0has also made an appearance in the Black Jack<\/em> (1973-83)<\/a> chapter\u00a0“Leaf Buds” as one of the boys in the class.<\/p>\n If you spot an appearance not already listed, please let us know in the comments section below!<\/p>\n Astro Boy<\/a><\/em>\u00a0(“Cobalt”) as “Cobalt”<\/p>\n Astro Boy<\/a><\/em>\u00a0(“Youth Gas”) as “Cobalt”<\/p>\n Astro Boy<\/a><\/em>\u00a0(“The Midoro Swamp”) as “Cobalt”<\/p>\n Astro Boy<\/a>\u00a0<\/em>(“Uran”) as “Cobalt” Astro Boy<\/a><\/em>\u00a0(“The White-Hot Being”) as “Cobalt” Astro Boy<\/a><\/em>\u00a0(“Robot Land”) as “Cobalt”<\/p>\n Astro Boy<\/a><\/em>\u00a0(“Demon Bees”) as “Cobalt” Astro Boy<\/a><\/em>\u00a0(“The Greatest Robot on Earth”) as “Cobalt”<\/p>\n Astro Boy<\/a><\/em>\u00a0(“Roboids”) as “Cobalt” Astro Boy<\/a><\/em>\u00a0(“Astro Boy Reborn”) as “Cobalt” Astro Boy<\/a><\/em>\u00a0(“Beginning of the Contradiction”) as “Cobalt”<\/p>\n Astro Boy<\/a><\/em>\u00a0(“The Man Who Returned from Mars”) as “Cobalt”<\/p>\nDistinguishing Features<\/h3>\n
