The dragons in Bone come in a variety of shapes (for example, the Great Red Dragon has rabbit-like ears and a goatee), but they're all large, intelligent fire-breathers who want what's best for the world. And then there's Mim, the Queen of the Dragons, who is part Ouroboros, part living Cosmic Keystone. She's several miles long, and capable of single-handedly causing The End of the World as We Know It. The dragon's culture has a high level of spiritual development and grants them further supernatural powers. The Great Red Dragon alone is telepathic, can astral-project through dreams, see the future, and communicate with the dead. Essentially, the dragons serve the role of angels, but are a mix of Western & Eastern Dragons (Fire-breathing & strength like Western ones, but mysticalness of Eastern dragons.
The Dragons in Gold Digger were originally genetically engineered by a long-extinct race called the Saurians. They come in four different flavors, Iron, Copper, Gold, and Platinum, who all look like Western Dragons with Platinums being the stand-out, having magical 'vents' instead of wings. Also hatching from dragon eggs are two sub-types, Wyrms and Drakes, who look like limbless dragons and two-legged two-winged (as opposed to the normal four-legged two-winged) dragons respectively and who get little rights in draconic society. All can turn into a human form, and all full dragons (but not wyrms or drakes) can intuitively use draconic magic which not even they understand the mechanics of, just the usage. Dragons tend to be highly intelligent, but arrogant as heck. The oldest dragon Exthilion ironically looks like an oversized Wurm with a frill, but has all the talents and magics of all the true dragon varieties.
In the alternate history fantasy series Arrowsmith, the protagonist is an airman, a soldier who flies by magically transferring the flight ability of a dragonet (baby dragon) into himself. Each airman has his own dragonet companion who typically rides his shoulder, and he wears strips of skin shed by the dragonet's mother to help form a bond between them.
The Fantastic Four villain the Dragon Man was a hi-tech robot built in the shape of a gargoyle-like dragon, animated by alchemy. It breathes fire, flies, and is super-strong. Despite its name, it does not especially resemble a man any more than your typical dragon does.
Lockheed, the dragon companion of the X-Men's Kitty Pryde, has many traits which western society considers common to dragons. He's reptilian, he has wings he uses to fly, he has a long snout with sharp teeth, breathes fire, and demonstrates intelligence beyond that of an animal. He is different from other dragons in that he's about the same size as a domestic cat, is purple, didn't say a word for many years despite being capable of speech, sometimes stands on his hind legs, and seems to have opposable thumbs on his front legs. And although not the same race as Fin Fang Foom, he is also an alien.
Dragons in the erotic comic Ironwood are all-male and reproduce by shapechanging into human males and seducing a woman; the offspring will be a full-blooded dragon, but for the first hundred years or so, he'll be infertile and trapped in human form (although ridiculously strong and tough). Since dragons enjoy sex as much as anyone else in the comic (if not moreso), they avoid overpopulation by tracking down adolescent dragons and trying to kill them (along with most of the town they're hiding in). This also ensures that a dragon that survives his "egg years" will be really tough.
CrossGen Comics's Scion features genetically engineered dragons used as aerial tanks by the techno-medieval Heron and Raven empires. A (seemingly) more conventional dragon appears in one arc of the straight-fantasy Crossgen title Sojourn.
The Savage Dragon is a comic hero who actually is not a dragon at all. He simply looks kinda like one, enough that it became his name.
To become the Iron Fist, a candidate must face Shou Lao the Undying, an Eastern dragon with a snakelike body. The mark of Shou Lao on an Iron Fist's chest has the serpentine body of an Eastern dragon plus a Western dragon's wings.
The dragons in Kairos are very humanoid, being roughly the size of a human, walking on two legs and having hands, wearing human clothes, and the female dragons have Non-Mammal Mammaries.
One of the guardians at the gate at Dream's castle in The Sandman is called Wyvern. Contrary to the usual appearance of a wyvern, the guardian is wingless and quadrupedal, with a long thin tail and neck and a bloated body, somewhat like a sauropod dinosaur (see for instance Chapter 3 of Season of Mists). It's probably intentional, as the guardian on his left side (our right) is called Hippogriff but is really a pegasus.
The Dragon that Hellboy fights to the death in The Fury is simultaneously the One-Winged Angel form of the Witch-Goddess Nimue and the unified aspect of the 7 Ogdu Jahad destined to bring the end of the world.
Morningbright the Dragon in Smax is a city-sized Lion/Arachnid/Peacock powered by fusion and sporting the attitude of Lucifer.
The Chalkydri in Crimson were dragons created by God during the creation of the Universe that fought on Lucifer's side during the War on Heaven and were imprisoned following their defeat. Their leader Sapha has multiple heads and is stated to be indestructible. He also has absolute control over his people, since as soon as he released from his prison, the dragons are unleashed as well and proceed to lay waste upon mankind. When Saint George sacrifices his life to imprison Sapha in the void, the dragons are gone as well.
Black Moon Chronicles: Many sizes and colors, but mostly cosmetic differences as they're pretty much all big (human to kaiju size) reptilian flyers with fire breath (except for undead ones and negation wyrms, who breathe unlife and oblivion respectively). Most are (or at least seem) sentient, though several look like they have the intelligence of a cat or chimp more than a human one.
