What is the dragon called in dungeons and dragons?

Answer 1

There are many dragons in Dungeons and Dragons, Chromatic dragons are seen as "evil" dragons; these are Red, Blue, Green, White and Black.

Then there are the "Good" dragons, or metallic Dragons, these being the Copper, Brass, Silver, and Gold dragons.

There are also other dragons that aren't as closely related, that aren't "true dragons" so to speak, including pseudo dragons and dragon turtles.

Well-known dragons include, but are not limited to, Bahamut (lesser deity of the metallic (not platinum in 3.5, at least) dragons), Tiamat (lesser deity of the chromatic dragons), Sardior (deity of the "gem dragons"), Gruaghlothor (ruler of the "ferrous dragons"), and Io (father of dragons).
