I know not very Tcest-y. Guess it doesn't have to be!
I'm pretty sure the animators in The Lost Episodes went "Fuck it" on keeping the a-symmetric tattoos Mike and Leo have consistent.

Have some more half dragons! Don is the easiest by far to draw. Mikey... oh mikey. His dragon form isn't incredibly dragonny. Other than keeping elements from the shell and the thick digging claws I can't do much for him.
