its in midjump, right? how does it look whan standing on earth (it looks like it's able to wallk on walls)?
Yes, it's in mid-dash. When I'm making the perspective shot I'll be sure to demonstrate it's 'on earth' rest stance.
I'm guessing it stands diagonally, front "claws" first. Or else if it stood normally up, it's hind legs would be kicking frantically.
Yes it can stand diagonally but it usually just has it's front limbs bent and splayed outwards
When attacking, it can reach it's front limbs forward with a slashing motion of it's claw and also uses it's solid head to ram it's victim.
The two prongs jutting from it's back are what used to be legs but now serve as a form of airbreak for rapid deceleration in air and water. They're also used to display when confronting rivals.
