What kinds of Metallic Dragons were ever shown in D&D products? [closed]

Everyone knows the iconic metallic dragons that come in almost every single core monster book, Gold, Silver, Bronze, Copper, Brass. Let's call those the "core five"

There were some others, like dunno Steel, Iron, Platinum, Electrum, Uranium(?), and what else...

What kinds of metallic dragons other than the "core five" were shown in D&D products?
What were their ecologies and demeanors?
In what worlds did they debut/existed?

Please edit the question to limit it to a specific problem with enough detail to identify an adequate answer. Avoid asking multiple distinct questions at once. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.

• While I think this may be too broad, there is likely a finite number of metallic dragons (as you note) so it may fit within scope. Suggest you include Bahamut as one of the core, as the Platinum dragon has been with us since Greyhawk supplement to OD&D – KorvinStarmast Nov 21 '17 at 17:37
• Having done the work for 3.5e, I think I agree with @KorvinStarmast—too broad. For one person to try to do the same for every edition, and then to put it into one answer, that would be too much, I think. – KRyan Nov 21 '17 at 18:22
• I think you could probably get away with separate questions for each edition, though. – KRyan Nov 21 '17 at 21:30

In D&D 3.5e, the most-complete listing of true dragons is in Races of the Dragon on pages 70-72. This list gives the stats of the half-dragon version of every dragon, and claims to be complete. However, the only apparent metallic dragons on the list are those from Monster Manual. Even other good-aligned dragons, namely the battle dragon, Oceanus dragon, and radiant dragon, don’t seem to be metallic. The list does mention the rust dragon from Draconomicon, which is arguably sort of metallic, but it’s notably lawful non-good.

Anyway, the Races of the Dragon list misses the steel dragon that you noted; the steel dragon was published in Dragons of Faerûn in August 2006, while Races of the Dragon was in January of the same year. Still, January 2006 covers a whole lot of the 3.5 life-cycle, so we do not have to search as many books to find other dragons. Monster Manual II and III are covered by Races of the Dragon, for instance, and Monster Manual IV has no dragons while Monster Manual V has only specific named individual dragons of existing types, not new types of dragons. Similarly, Dragon Magic focuses on magic available to and/or derived from dragons, and while it has many options for dragons, it does not have any new dragons itself.

Magic of Incarnum is semi-notorious for having a dragon, the incarnum dragon, that Races of the Dragon missed—it was published in September 2005, not long before Races of the Dragon, but nonetheless. (This is semi-notorious because its absence has been used as justification for not seeing dragonwrought kobold’s absence in the list as definitive of anything.)

So OK, every book published since September 2005, then. Using HeyICanChan’s handy list, then:

\begin{array}{l|l|l|c|l} \text{Year} & \text{Mo} & \text{Title} & \text{Checked} & \text{Findings} \\ \hline 2005 & 09 & \textit{Magic of Incarnum} & \checkmark & \text{incarnum} \\ & & \textit{Sons of Gruumsh} \\ & 10 & \textit{Heroes of Horror} & \checkmark \\ & & \textit{Magic of Eberron} & \checkmark \\ & 11 & \textit{Champions of Valor} & \checkmark \\ & & \textit{FL:Hellspike Prison} \\ & 12 & \textit{Spell Compendium} & \checkmark \\ \hline 2006 & 01 & \textit{Player's Guide to Eberron} & \checkmark \\ & & \textit{Races of the Dragon} & \checkmark \\ & 02 & \textit{Red Hand of Doom} \\ & 03 & \textit{Power of Faerûn} \\ & & \textit{Tome of Magic} & \checkmark \\ & 04 & \textit{Complete Psionic} & \checkmark \\ & & \textit{FL:Fields of Ruin} \\ & & \textit{Voyage of the Golden Dragon} \\ & 05 & \textit{Player's Handbook II} & \checkmark \\ & 06 & \textit{Fiendish Codex I} & \checkmark \\ & & \textit{Mysteries of the Moonsea} \\ & 07 & \textit{FL:Dragondown Grotto} \\ & & \textit{Monster Manual IV} & \checkmark \\ & & \textit{Secrets of Xen'drik} & \checkmark \\ & 08 & \textit{Dragons of Faerûn} & \checkmark & \text{mercury, mist, steel} \\ & & \textit{Tome of Battle} & \checkmark \\ & 09 & \textit{Dragon Magic} & \checkmark \\ & & \textit{Faiths of Eberron} & \checkmark \\ & & \textit{Twilight Tomb} \\ & 10 & \textit{Complete Mage} & \checkmark \\ & & \textit{Expedition to Castle Ravenloft} & \checkmark \\ & 11 & \textit{Cityscape} & \checkmark \\ & & \textit{Dragonmarked} & \checkmark \\ & & \textit{Scourge of the Howling Horde} \\ & 12 & \textit{Animated Series Handbook} \\ & & \textit{FL:The Frostfell Rift} \\ & & \textit{Fiendish Codex II} & \checkmark \\ & & \textit{Shattered Gates of Slaughtergarde} \\ \hline 2007 & 01 & \textit{Complete Scoundrel} & \checkmark \\ & 02 & \textit{Barrow of the Forgotten King} \\ & & \textit{Dungeonscape} & \checkmark \\ & & \textit{Secrets of Sarlona} & \checkmark \\ & 03 & \textit{Magic Item Compendium} & \checkmark \\ & & \textit{Cormyr} \\ & 04 & \textit{Eyes of the Lich Queen} \\ & & \textit{Ett.

$Ett.$ is short for “Expedition to the,” and $FL$ stands for “Fantastic Location.”

So it seems that the mercury dragon and steel dragon were the only additional metallic dragons to ever be published by Wizards of the Coast for D&D 3.5e. Note that web articles and/or officially-licensed-but-not-WotC-published sources like Dragon magazine are not covered (HeyICanChan notes in a comment that Dragon included adamantine, chromium, iron, nickel, sodium, and tungsten dragons). And, of course, there are many books I don’t own myself to check; none of these seems very likely to have a dragon, but there are enough of them that it seems hard to claim that none of them do.

I cannot comment on other editions, as I do not have the resources to embark on a thorough search like this for them.

• If anyone has access to a book I don’t have checked off here, feel free to check it and either let me know, or edit in a & \checkmark for that book yourself. – KRyan Nov 21 '17 at 18:38
• I found the same for 2e; only steel and mercury are additional metallic dragons. – KorvinStarmast Nov 21 '17 at 20:50
• @KorvinStarmast While it may be beyond this answer's mandate, Dragondex also lists as having been published in Dragon the adamantine, chromium, iron, nickel, sodium, tungsten, and rust dragons (the last may or may not warranting inclusion). – Hey I Can Chan Nov 21 '17 at 21:29
• @HeyICanChan I don't think we are including the Dragon magazine "idea forum" as canon. I prefer to limit the scope the way KRyan has ... I was reading an early Dragon issue the other day, and Kask made a very clear statement: the stuff in Dragon for OD&D and 1e, at least, was "use it if you want, or not, in your campaign." That isn't "canon" like stuff in published books. – KorvinStarmast Nov 21 '17 at 21:30
• Man, that's a thorough answer. (It's also a great testimony to how much bloat hit 3.5 ...) – KorvinStarmast Nov 21 '17 at 22:02
