I've been really inspired to create my own fan dragon species for the How To Train Your Dragon universe after I've been designing nothing but Fury species for a while. So meet the Streamliner.

For a long time I've really wanted to design a tidal class Eastern dragon in the HTTYDverse (and I mean TRADITIONAL serpentine Eastern dragons, not that ugly two-headed unbalanced mess that Wu and Wei from The Nine Realms are).

And since the HTTYD dragons are notorious for being directly influenced by real animals I wanted the Streamliner to strongly resemble an otter. There's a BIT of a seal inspiration in my design too, but I mostly referenced otters, given Eastern dragons' strong association with water and how they borrow more from mammal traits than reptile traits

Despite being mostly aquatic, Streamliners can still fly even without wings by swimming and gliding through the air. Don't question how it works, that's just how it is with traditional Eastern dragons. Streamliners typically come in blue, green, or white, or something in between.
