Super Sheng Long - he is from Dragon Ball Super. He is the absolute largest Dragon in all fiction that I know of. Super Sheng Long is so big, he dwarfs galaxies, as you can see below. He is “slightly” bigger than Chou Tengen Toppa Gurren Lagann, who is 52.8 billion light years tall. He measures some 57 billion light years in length, I don’t even know how many miles long that is. Super Sheng Long is a Universal-Class Dragon capable of eating galaxies, and is the largest dragon we have to date.


Unlike some of the “questionable size” dragons here like Samal Naga, Jormungand, Tiamat and Bakunawa who come from ancient mythology that didn’t have our current understanding of the galaxy, Super Sheng Long was created with full knowledge that galaxies are ridiculously large. And this is his honest to goodness depiction. He is legit the largest dragon ever made.
