The dragon he’s sharing is from World of Warcraft PC video game character, which is called Deathwing.
World of Warcraft is a massively multiplayer online role-playing game . Even though it is said to be an MMORPG I don’t remember ever playing it like that. All I remember is that I play DOTA and Tower Defense Map on it.
Anyway, Deathwing the Destroyer, formerly known as Neltharion the Earth-Warder was one of the five Dragon Aspects and leader of the black dragonflight .
Well there’s many more story behind Deathwing but I’m not going into the details much .
As for Deathwing origami here’s the video on how to build it by Doreng4287.
Building one isn’t easy as you have to create many small origami parts and combine it together to make into a dragon.
