Fafnir (Dragon Boy)

Fafnir (ファフニール Fafunīru), or Takeshi Ooyama (大山 猛 Ōyama Takeshi), is a supporting character in the Miss Kobayashi's Dragon Maid series and the main protagonist of Miss Kobayashi's Dragon Maid: Fafnir the Recluse. He is an old friend of Tohru and the roommate/friend of Makoto Takiya

In his human form, Fafnir appears as a handsome young man with straight waist-length or hip-length black hair that is in a loose ponytail at the end with bangs covering his right eye, red eyes that can change color and size depending on when angry and he has a calm, collected demeanor that reflects his slightly gloomy face.

When Fafnir is in his dragon form, he appears as a towering dark dragon with several thick, smooth tentacles instead of legs, with the two longest ones working as a tail. He has large dark wings with a feathery appearance. He has a long snout, a circular mouth with two vertical rows of fangs and has three pairs of pure red eyes. He has four horns, two smaller horizontal ones on top and below them two thicker horns that curve forward to eye level.
