Adamant / Adamantine | Greek mythology | As a noun , adamant has long been used to designate any impenetrably or unyieldingly hard substance and , formerly , a legendary stone/rock or mineral of impenetrable hardness and with many other properties , often identified with diamond or lodestone . The English word is used both as a noun and an adjective and is derived from the Latin : adamans , adamantem [ accusative ] referring to the property of impregnable , diamondlike hardness , or to describe a very firm/resolute position , itself from the Greek word adamastos meaning untameable . Diamond is also derived from the same word . Adamant and the literary form adamantine ( utilising the suffix -ine meaning 'of the nature of ' or 'made of ' ) occur in many works . In mythology Kronos was said to have used an adamantine sickle to castrate his father Uranus ; in Prometheus Bound , Prometheus is bound to the rocks in adamantine bonds infrangible , in Virgil 's Aeneid ( in which the gates of Tartarus are protected by columns of solid adamantine ) and in Paradise Lost , in which adamant and adamantine are mentioned eight times to describe the gates of hell , Satan 's shield , fallen angel 's armour and Satan 's chains . In fiction Adamant is referred to in The Faerie Queene , Gulliver 's Travels , A Midsummer Night 's Dream , The Lord of the Rings , His Dark Materials trilogy , and the games Final Fantasy and RuneScape and many more besides . Adamantine is referred to in the film Forbidden Planet ( as adamantine steel ) , in many books such as Mary Shelley 's Mathilda , and Mark Twain 's The Adventures of Tom Sawyer , as well as many games including Dungeons & Dragons . The word adamant is used as the basis for other fictional materials such as Adamantium ( see below ) , Adamantite ( see below ) , Adamantle ( from the Sims ) , and Adiamante ( from L. E. Modesitt Jr. 's 1996 novel of the same name ) | Adamantite | Numerous works | A metal ore that appears in a number of fictional universes . In Final Fantasy it is a material used to create armour , its source being from another world and its properties including being able to contain great amounts of energy . In World of Warcraft , it is an uncommon ore used to produce weapons and armour of uncommon , rare and epic grade . In the Dark Elf book series by Salvatore set in the Dungeons & Dragons universe it is used to create drow weaponry . It is also used for armour in The Elder Scrolls III , and in the game Terraria it is a red ore used to produce armour and other items besides . The word is an extension of the English noun and adjective adamant ( see entry above ) adding the suffix '-ite ' which is often used to form the names of minerals | Adamantium | Marvel Comics | A fictional metal alloy that appears in the Marvel Universe , first appearing in Marvel Comics ' Avengers # 66 ( July 1969 ) , by writer Roy Thomas and artists Barry Windsor-Smith and Syd Shores . Although it is first presented as part of the character Ultron 's outer shell , it is best known as the substance bonded to the character Wolverine 's skeleton and claws . The defining quality of adamantium is its practical indestructibility . Adamantium is not depicted as being a naturally occurring metal but rather as having been inadvertently invented by the fictional American metallurgist Dr. Myron MacLain in an attempt to recreate his prior discovery , a unique alloy of steel and vibranium . Despite its potential applications in armament and armature , adamantium is rarely used due to its high cost and inability to be reshaped . Other forms of adamantium of varying durability are mentioned within the Marvel Universe , including Secondary Adamantium , Adamantium Beta and Carbonadium . Aside from Ultron 's outer shell and Wolverine 's skeleton and claws , Adamantium is associated with a number of other characters and implements including , but not limited to , Bullseye 's spinal column , certain iterations of Captain America 's shield and Lady Deathstrike 's skeleton and talons . The word is an extension of the English noun and adjective adamant ( see entry above ) adding the Neo-Latin '-ium ' to denote a metallic name . Adamantium is also used in the Games Workshop universe of Warhammer 40000 and the MMORPG Maplestory | Administratium | Scientific in-joke | First referenced in a 1989 issue of The Physics Teacher . It was apparently discovered by the fictional Thomas Kyle , who was awarded an Ig Nobel Prize for physics for his discovery , and it is a parody on bureaucracy of scientific establishments and on descriptions of newly discovered chemical elements | Administrontium | Scientific in-joke | Similar to Administratium and a variation of the joke .
