I think there are the following dragons in Inuyasha:
Qinglong
Sesshomaru's arm was cut off by Inuyasha's iron teeth, so he traded the arms of some powerful monsters for his own. But change won't work. Sesshomaru went to kill a dragon and changed its claws. Sesshomaru attacked the broken iron teeth with his dragon claws, and the broken iron teeth were almost unbearable.
Dragon of the Moon
Kaijin Bou made two famous weapons, one is the ghost battle of Sesshomaru, and the other is the long sword of Huang Xing Gan Kun. Huang Xing has four monsters who are good at ninja. One of them is the Moon Dragon. This dragon is taken from four elephants. Dragons are half-human, and there is an obvious dragon forest. Some strength, but not very strong.
Long Gujing
Long Gujing, I don't know whether it's a python or a keel or something. At least it is still like a dragon. Inuyasha's father was an old enemy of King Dou-tooth, and was sealed by King Dou-tooth, which also seriously hurt King Dou-tooth. However, only when Inuyasha gains experience can Inuyasha learn how to break out.
Dragon Man
Knife maker Dao Qiu collected swords containing Yin qi and resentment, which attracted the Dragon Man, who gave them to Long Lin to make demon knives to seize ghosts. As a result, the Dragon Man was defeated by Inuyasha, and Daoqiu took advantage of this opportunity to seize the demon power of the Dragon Man. Ghosts are formally formed and have the ability to catch other demons' swords. If catching ghosts is not afraid of being broken, and the damage is transferred to the knife mound, the hard iron-proof teeth are likely to be broken.
Red Dragon
There is still a heaven in Lei Shou clan who wants revenge on Inuyasha, especially Qibao. There is a red dragon under heaven, which is a red-covered, mini-cute version of the western dragon image. As a result, the Red Dragon was beaten by Inuyasha, and it seems that Inuyasha likes beating Meng Chong very much. By the way, the seiyuu of Red Dragon in Japanese is the same as the seiyuu of Qiao Ba in One Piece.
Longluo
Longluo is one of the four fighting gods, and the four fighting gods also have the meaning of four spirits in the southeast, northwest and northwest. Dragon Luo belongs to the Oriental Dragon and is the most handsome dragon in Inuyasha. There are two African claws on the shoulder, holding double knives, and Long Lin is also on the exposed arm.
These are all dragons in Inuyasha. The above is just a personal opinion.
