This is Pockis' father, Dovah.
Gender: Male
Species: Hornagonn ( own species)
Age: Full Grown Adult ( they live a long time like dragons so hard to say exactly. lets just say hes the same age as Princess Celestia, give or take a few years)
Element: Fire
Weakness: Darkness and Wind. He is pretty tough but he can get hurt. Dovah usually heals completely but if faced with a tough opponent the mark will stay. (i.e. the scars on his ear while he was protecting his family)
Personality: Dovah is serious at most business occasions but can be lovable to his family. He is very king yet strict.
Ruling: Dovah is the king of the Hornagonns. He is known to be the tallest of his species, other than the Elders ( need to draw them eventually)
Cutie Mark Meaning: The cutie mark represents the main elements (ie fire, earth, water, and air)which in Dovahs case, his main breath is fire.
There is a main alpha in each element which each have a similar cutie mark but different colored stones in the middle of the wings. Since fire is the most powerful breath in dragon terms Dovah is the most powerful. Think as if its like King Arther or something.

Thanks for sticking through his backstory. this may answer some questions about Pocki ( or not) Sorry if its a little confusing. I'm still working on the story. I really wanna make a comic but unsure how to do it. If you have any pointers feel free to post it in a comment.
I will also post a armored version and a size chart comparing both him and Pocki to the show very soon.

I hope you like him and thanks for reading.
