Tronkdar

Tronkdar, known as the Iron Kaiser, is the foster father of both Zeno and Boo Drollinger.

Appearance
Tronkdar is a skinny yet heavy dragon covered in mostly black and silver scaled. The top part of Tronkdar's body is covered in bright metallic silver from head to tail while his underbelly mostly consists of black matted scales. His body is covered in what appears to be a spiny exoskeleton, but upon closer inspection, it is merely his scale structure of which he shaped to be spiny and rugged. The scales on his chest and shoulders seem to form a chestplate, and the silver scales on his head seem to form a helmet. His wings are encased in silver scales which he can then use as added protection. His eyes are covered by a formation of scales around and over top of them. Tronkdar has a very slim yet sharp jawline and claws.

Personality
As a father, Tronkdar was extremely strict and highly valued discipline. Despite him leaving his sons, he still cares for them greatly, and would be devastated if anything happened to them. It can sometimes be unsettling to how aggressive and sadistic he can be towards enemies. He got his name, The Iron Kaiser for his unmerciful nature and fighting skills.
