I'm in way over my head as this is going to be a lot harder than just drag-and-drop (Godot isn't as awesome with animations as I thought it was). Sure Bones help but there's also all the art for (I only have faces) clothes and opponent's (on the right). This game needs a smaller scope with simpler models! These awesome 12-part models are more complex than the inspiration (Paper Mario) anyway.

PS: You might have noticed the cross-hairs like in my last image. These are the extremities that, when moved, change the limbs accordingly. Inverse Kinematics are nice.
