Dragons in Charby the Vampirate live near humans and enjoy human entertainment and amenities since they can pass as human if they so desire. While they seem to have plenty of half-elf offspring most of the denizens of Kellwood distrust them, with at least one society having hunting down and killing a dragon as a required rite for boys to enter adulthood.
Dark Wings has the gargantuan Great Dragons, the never-seen-on-panel common dragons, and the small but crafty wyverns. All have approximately human intelligence.
The former title character of Daryl And Susie is a dragon. He, and other dragons like him, is bipedal, is about the same size as a human and resembles a crocodile with wings. One trait that Daryl doesn't share with his fellow dragons though, is that he has monsters come out of his head.
Dominic Deegan has dragons as well, but only one ever shows up. They're more along the lines of western dragons in appearance, as well as colossal in size and capable of powerful magic. Apparently their language and beautiful and lyrical to the ear, but the one we see speaks a very different language so Dominic never gets to hear it himself. Plus, they're very rare, so if ever one has the opportunity to meet one is considered incredibly lucky.
Dragon City has bipedal dragons who are roughly human-sized and live underground, typically underneath human cities. At least until the Ambis disintegrated the human population of Chicago and the dragons moved in. Also they coexisted with the dinosaurs and started hiding underground before the asteroid hit. Their fire-breathing has atrophied over millions of years, they have the glands that produce it but if they try breathing flame they burn their throats so many have their flame-sacs removed as hatchlings.
Dragons in The FAN are deities. They never appear, but a common depiction of Galion, the Dragon of Light is humanoid.
The dragons in Far to the North fit the Western Dragon mold relatively well, breathing fire, flying on bat wings, and seeking to 'collect' one of the protagonist's nieces to keep as a pet. The fact that they've apparently created the entire goblin race from scratch suggests they have abilities we've yet to see though.
George the Dragon has a dragon named... well, what do you know...George. As far as we've seen he is the ONLY dragon on earth, and he certainly DOES get around a bit. He is the regular 4 legs and 2 wings variety but his wings tend to come and go and will. Also of note, George's diet seems to consist entirely of junk food.
The first dragon featured is the Dragon King of Mars in one of the fictional Heterodyne Boys stories. He looks like a robotic Western dragon. Mars, in this story, seems to be inhabited by such robot dragons.
The Great Sky Wurm, originally of the Polar Ice Lords, now battle loot of Baron Gilgamesh. E-frikkin'-normous, but can only fly in the cold.
Kay The Cookie Jar Dragon is actually a miniature Cute Monster Girl. One of the characters hangs a lampshade on this, talking about all the things that dragons should be; Kay simply replies, "But I am a dragon", and this is taken as a perfectly good excuse.
The colour coding of dragons appears to have been slightly subverted recently with the mother of the dragon killed by Vaarsuvius turning up. She is quite loving of her (now dead) son and husband, and was apparently "open-minded" enough to tolerate her son having a crush on "a nice green dragon". Her grief over her son's death has led her to a vendetta against Vaarsuvius. However, she's still clearly evil through and through.
Speaking of part-dragons, there's the entire Draketooth family, who are shown to have had a number of unique dragon ancestors at the top of their family mural. These include something resembling a female Yuan-ti or Naga, a humanoid with black scales and wings and a Devil-ish figure with a human head, black scaled body, a tail and a horn (and a goatee). All of the people descended from these three have purple dragon markings on their head.
Llewellyn of Ozy and Millie is essentially a lovably eccentric Englishman — and a wise, kind-hearted adoptive father — in dragon form. Oh, and he's also Really 700 Years Old.
"Lovably eccentric" is pretty much dragons' hat in Ozy and Millie. During a family reunion, Ozy won a game by being suitably Zen in his justification for not participating to begin with.
Sluggy Freelance featured a flower-breathing dragon that "terrorized" the Dimension of Pain for a while... until Reakk boinked it.
Aylee also took on a fire-breathing dragon form for a while, as a reaction to being stuck in cryo for months. Most of her forms after that and the one just before it were dragon-like.
The flower-breather was one of three "Dragons of Annoyia". Another one was a nebbishy sort who didn't appear to breathe anything, but was pretty much the embodiment of everything you can find annoying about another person.
Erfworld's "dwagons" are diffewent, resembling giant stuffed toys. However, in combat they seem to be about as tough and dangerous as traditional Western dragons.
They also seem to be non-intelligent, though its hard to tell with any of the basic troops. Basically only warlords get lines.
ThisPenny Arcade comic involves a calling out out on essentially, a book's dragons being not-so-different.
Four God Ranger: The only dragon seen so far is one of the Four Celestial Gods, Seiryu. He, along with the other four gods, has the form of a bipedial humanoid creature that is a hybrid human/celestial god. He also has healing powers and seems to be the defacto leader of the group.
The Inexplicable Adventures of Bob! posits that dragons evolved from kuehneosaurs. They had an advanced civilization but destroyed it in a war, taking the dinosaurs with them. The survivors became pastoral. When humans evolved and came into conflict with them, the dragons avoided a war with the primitives by leaving Earth for Butane, a planet in the Kuiper Belt. They are part of Princess Voluptua's space empire.
Linburger. The dragon was long and looked like an eastern dragon. However, it was just a very big beast and devours anybody caught outside like a western dragon. If you kill one, the body will release pheromones that attract hundreds, so the government just leave them alone to chomp on slum residents until it leaves.
Planes Of Eldlor features five subspecies: Fire, storm, desert, swamp, and riftwalker dragons. Each has distinctive features and abilities, though all of them share the classic "western dragon" appearance of having four legs and large, batlike wings. The dragons of Eldlor are benevolent and intelligent, but somewhat reclusive - though occasional mischevious pranksters like Sukozu enjoy visiting human villages just to "see the looks on their faces."
The Law of Purple: 'Dragons' are actually higher-dimensional creatures that spend most of their time in another plane of existence.
Alternia of Homestuck has a species of dragons, the Dragonyy'yd. They are all telepathic, but are blind until maturity. As such, they sense through smell. These dragons are highly intelligent, and can even communicate with the outside world before their egg hatches. Terezi and her Ancestor, Redglare had one as her Lusus. This came in handy for the former after she went blind.
Deviant ARTThis rendition of a multi-headed dragon by artist IRIRIV. Instead of the typical dragon, the Centocephalic Dragon has an almost sauropod-like body with half its 100 long serpentine heads moving and twirling around the rest of the body to aid in balance and efficiency. Along with its normal set of limbs, it also uses it's wings to aid in walking (leaving the artist to wonder why normal dragons do not use this mode of locomotion considering their huge size). Instead of fire, it spits molten metal that not only burns but hits hard.
There is also the Eastern Dragon who is the embodiment of the East Asian religions.
Played With in ‘’Keeping The Peace’’. Two of the universes have dragons. Dragons like Stalix are around the size of an elephant at most, can talk, and seem to have average human wisdom. Dragons from Shaun’s world are the size of a building, don’t talk and have such low intelligence that they can be at the beck and call of a summoner. The contrast catches a few people by surprise.
The ones in Tales of the Questor are old-school Western dragons. However, instead of hatching, they are spawned from some kind of evil meteor. Surrounding animals such as livestock and, later on, poisonous and venomous creatures accrete onto the meteorite, falling into the crater and melting, until the resulting blob of flesh has enough mass to transmute into a new dragon. Also, dragons are lux-proof, and go absolutely berserk if another dragon is killed where they can find it.
Fairy Dust's dragons are very similar to regular lizards in appearance and behaviour. Some species are domesticated and are easy to tame, but they otherwise act like normal animals. Their fire breath, large mature size and some species' wings differenciate them from ordinary reptiles.
