That's where you went astray. A Doom Horror is supposed to be nastier than a dragon. Just think for a minute the sorts of images that the words "doom" and "horror" bring to mind, then consider what something called a "Doom Horror" (note the two capital letters) might be capable of. A dragon may be terrifying to behold, and capable of horrific carnage, but a creature that bringeth Doom is another order of magnitude entirely.
