Origins Medieval literature scholar
Thomas Honegger considered it "no coincidence" that the seminal role-playing game "features the dragon, a most formidable opponent, as the second element of its name" as the "recognition of the dragon as the most dangerous animal is traditional" in epic literature. Five evil-aligned dragons (white dragon, black dragon, green dragon, blue dragon, and red dragon), and the lawful-good aligned golden dragon (in ascending order of magic power and capabilities) first appeared in the original
Dungeons & Dragons "white box" set (1974). The white dragon, black dragon, red dragon and brass dragon reappeared in the original
Dungeons & Dragons Basic Set (1977). The six dragons from the 1974 boxed set appeared in the
Dungeons & Dragons Basic Rulebook (1981), and again in the 1983 version of the
Basic Set (1983). These six appeared along with the gemstone dragons (crystal dragon, onyx dragon, jade dragon, sapphire dragon, ruby dragon and amber dragon), and the dragon rulers (Pearl (the Moon Dragon), Ruler of all Chaotic Dragons; Diamond (the Star Dragon), Ruler of all Lawful Dragons; Opal (the Sun Dragon), Ruler of all Neutral Dragons; and the Great One, Ruler of All Dragonkind) in the
Dungeons & Dragons Rules Cyclopedia (1991). The five chaotic-aligned dragon types from the 1974 boxed set, as well as the gold dragon and the four new dragon types from the
Greyhawk supplement (the copper dragon, brass dragon, bronze dragon, and silver dragon) appeared in first edition
Advanced Dungeons & Dragons in the original
Monster Manual (1977), along with Bahamut and Tiamat. The former five dragon types were given as evil-aligned, while the latter five dragon types were given as good-aligned. The ten dragon types were given pseudoscientific names as follows: black (
draco causticus sputem), blue (
draco electricus), brass (
draco impudentus gallus), bronze (
draco gerus bronzo), copper (
draco comes stabuli), gold (
draco orientalus sino dux), green (
draco chlorinous nauseous respiratorus), red (
draco conflagratio horriblis), silver (
draco nobilis argentum), and white (
draco rigidus frigidus). The Oriental dragons appeared in the original
Fiend Folio (1981), including the li lung (earth dragon), the lung wang (sea dragon), the pan lung (coiled dragon), the shen lung (spirit dragon), the t'ien lung (celestial dragon), and the yu lung (carp dragon). The cloud dragon, the faerie dragon, the mist dragon, and the shadow dragon appeared in the original
Monster Manual II (1983).
Second edition In the
second edition of Advanced Dungeons & Dragons (
AD&D), dragons were altered heavily from their first edition equivalents and were made much more powerful with magic resistance, removing the subdual rules, and now had more physical attack forms besides claws and bites.
AD&D 2nd edition and
D&D 3rd edition divided true dragons further into three main categories:
chromatic dragons which are evil-aligned;
metallic dragons which are good; and neutral-aligned
gem dragons, rare creatures that possess
psionic abilities. In addition, there were other subspecies of true dragons that did not fit into the three main categories. For example, mercury and steel dragons would seem to be metallic dragons, but in the
Dungeons & Dragons world they are considered to be outside of the main family of metallic dragons because of various biological differences (though the book
Dragons of Faerûn did list them as metallic dragons). The "lung dragons" or spirit-dragons of
Oriental Adventures are also true dragons. The black dragon, blue dragon, brass dragon, bronze dragon, copper dragon, gold dragon, green dragon, red dragon, silver dragon, and white dragon appeared in second edition
Advanced Dungeons & Dragons in the
Monstrous Compendium Volume One (1989). The faerie dragon, and the Oriental dragons—lung wang (sea dragon), pan lung (coiled dragon), shen lung (spirit dragon), t'ien lung (celestial dragon), tun mi lung (typhoon dragon), yu lung (carp dragon), chiang ling (river dragon), and li lung (earth dragon)—appeared in the
Monstrous Compendium Forgotten Realms Appendix (1989). The radiant dragon appeared in the
Spelljammer: AD&D Adventures in Space boxed set (1989). The dragons of Krynn', the , the astral dragon, the , the , and the sea dragon appeared in the
Monstrous Compendium Dragonlance Appendix (1990). The cloud dragon, the Greyhawk dragon, the mist dragon, and the shadow dragon appeared in the
Monstrous Compendium Greyhawk Appendix (1990). The adamantite dragon appeared in the
Monstrous Compendium Outer Planes Appendix (1991). The moon dragon, the sun dragon, and the stellar dragon appeared in the
Monstrous Compendium Spelljammer Appendix (1991). The deep dragon appeared in the
Monstrous Compendium Forgotten Realms Appendix II (1991). The gem dragons (the amethyst dragon, the crystal dragon, the emerald dragon, the sapphire dragon, and the topaz dragon) first appeared in
The Dragon magazine #037 (May 1980), and then appeared again in the
Monstrous Compendium Fiend Folio Appendix (1992). The chromatic dragons (black dragon, blue dragon, green dragon, red dragon, and white dragon), the gem dragons (amethyst dragon, crystal dragon, emerald dragon, sapphire dragon, and topaz dragon), metallic dragons (brass dragon, bronze dragon, copper dragon, gold dragon, and silver dragon), brown dragon, cloud dragon, deep dragon, mercury dragon, mist dragon, shadow dragon, steel dragon, and yellow dragon appeared in the
Monstrous Manual (1993). The onyx dragon, jade dragon, ruby dragon and amber dragon appeared in the
Monstrous Compendium Mystara Appendix (1994).
Third edition The chromatic dragons (black, blue, green, red, and white), and the metallic dragons (brass, bronze, copper, gold, and silver) appeared in the third edition in the
Monster Manual (2000), and in the revised 3.5
Monster Manual (2003). Their depictions by
Todd Lockwood and
Sam Wood tried to incorporate the "very inventive" original designs by
Dave Sutherland from 1st edition while making them anatomically more credible, and differentiate all species through distinctions in wing-shape in addition to head details. 3rd edition's is "what Wizards designers now consider the "definitive" representations of these monsters." The third edition of
D&D classifies dragon as a type of creature, simply defined as "a reptilelike creature, usually winged, with magical or unusual abilities". The dragon type is broken down into several classifications. True dragons are dragons which increase in power by age categories (wyrmling to great wyrm). Lesser dragons do not improve in age categories and may lack all of the abilities of true dragons. Examples of lesser dragons include
dragon turtles and
wyverns. Other creatures with the dragon type include drakes, , elemental drakes, landwyrms,
linnorms and wurms.
Fourth edition With
D&D 4th edition, the classifications were changed: chromatic dragons turned not strictly evil, and metallic dragons proved not necessarily good. There are also several new categories (although the gem dragons did not return): "planar dragons" which are defined as dragons that were warped by living on a plane of existence other than the Material Plane, "catastrophe dragons", which take on the aspects of natural disasters that are chaotic evil and cause chaos for its own sake, and "scourge dragons". The five chromatic dragon types (black, blue, green, red, and white) appeared in young, adult, elder, and ancient variants in the fourth edition
Monster Manual (2008). Chromatic dragons were again presented in the
Draconomicon: Chromatic Dragons. This supplement also included three more chromatic dragon types: the brown dragon (aka, sand dragon), the grey dragon (aka, fang dragon), and the purple dragon (aka, deep dragon). The adamantine dragon, copper dragon, gold dragon, iron dragon, and silver dragon appeared in the
Monster Manual 2 (2009). Metallic dragons are presented in the
Monster Manual 2 and
Draconomicon: Metallic Dragons. Catastrophe dragons are presented in
Monster Manual 3. Planar dragons have been presented in both
Draconomicon: Chromatic Dragons and
Draconomicon: Metallic Dragons.
Fifth edition The five basic chromatic dragons (red, blue, green, black, and white) and metallic dragons (copper, brass, silver, gold, and bronze) appeared in the fifth edition
Monster Manual (2014) in wyrmling, young, adult, and ancient. Gem dragons and other new-to-fifth-edition dragons appeared in ''Fizban's Treasury of Dragons'' (2021). == Game mechanics ==
