Very cool! The armor--especially the tail--really rocks. I like the miniatures of his head, too, although the roaring one is my favourite and his jaw structure looks different there from on the big picture.
Yup, he can dislocate his jaws, like a snake, for a more powerful bite ( if he really has to bite, 'cause he doesn't like that xD ), and his horns have a weird, seahell-like looks because they are used to make different loud sounds (like a parasaurolophus ), but he uses them as a weapon, creating such loud howls and roars( a variation of Force Scream ), that they can destroy a living being's eardrums, leaving his enemies deaf and disoriented
Yup, he's an admiral in a CIS fleet, and, well, he really looks like a human with blue-grey skin and grey hair, but can turn into this... thing XD, if he wants to, every korung kan. But his beast form is a bit bigger and looks a little different, 'cause he's a force-user
