Wayne is a King Cobra naga that is more king cobra but has some dragon blood within him. His mom was a King Cobra while his dad was a western dragon and he is just like his mother but his blood is mixed. He is a decent size of 55 ft long and enjoys nomming other nagas and snakes, he finds them delicious and usually likes to nom them while they are still alive. He only digests snakes and nagas that do evil to other prey or has too much evil plans that he finds crazy, but for the ones willing to go into his belly he keeps them safe in his belly and it helps in concentrate when he is working on a project. Wayne has 2 stomachs one in his upper body and in his coils. His upper belly is safe to be in he stuffs smaller prey in there for safe keeping to study them while his lower belly stuffs big prey inside to digest them when he is in cycle of not being safe and the willing ones he stuffs in there to let them rest and sometimes drinks a potion to make sure its safe to be in before he noms them.
Dazi is a kobold that loves his big size and gladly wanted to help him out with projects and other things at first Wayne didnt want someone but he has grown attached to his servant.
One day while working Wayne made a special concoction that would be able to change his gender and had some of his dna inside and Dazi accidentally tripped and hit the table the potion was on and the contents fell on his skin and it slowly changed his size to where he is bigger then your average kobold. Wayne at first was concerned for his fave servant but Dazi wanted to test out his new body and enjoyed how he is able to change his gender and now has a longer tail that can snag things super fast and Wayne smiled and used a spell on his belly to give him the same tattoo as he has but with a different color to show he belongs to Wayne and now his belly can stretch like Wayne can to devour prey. Dazi with his new found body has a craving for his own kind just like Wayne is with snakes and nagas and doesnt mind them inside.
