This here is Umnus!

He's a space-faring metallic draconic being.
His insides are like a furnace and he constantly vents heat via his smoke-stack horns.
When he opens his mouth it has a red glow emanating from the back of the throat and smoke once again billows out.

He actually has six of those 'vents' on his back, (they can better be seen here on Dae's image of him and also the reason why I'm uploading this now haha)
He uses those and his 'flower' to fly and travel through space, going to different planets.

All this naturally makes him warm to the touch and his gimmick it's of not that the larger his womb/middle gets the more it glows making him become in many ways a red sun/red giant.

He is a well traveled fellow with a warm (haha) and curious nature.

Did I also mention this guy is McHeckin' big?
He's like... 17'0" big.
