I used to run a Pokemon interactive blog where I drew Noiverns every single day (this is not exaggerating; it was the whole gimmick/point of the blog). Considering the ridiculous number of drawings (I ran it for over a year) as well as the obviously variable quality, I’m just uploading the stuff I’m very proud of rather than the stuff that ranges from average to sketches. Even that stuff is still pretty old.

These were most of the characters (not including the side character Zoroark, Nightshade) in a question about fav weathers.
Estrella: top, biggest, most “normal” noivern
Toby: smallest, no neck, dark blue under-wings and a pinker purple
Jax: has separate wings and arms, has orange on him rather than purple
Colette: shiny
