>>38758695Pokemon are fantasy creatures that can have ever-burning flames adorning their body, coins stuck to their foreheads, gaseous bodies, steel carapaces or skin, or straight up energy auras. So no, they don't have to be made of flesh and bone. Sylveon's ribbons can actually just be ribbons, still part of its body, but not made of flesh and wouldn't bleed if cut, in the same way a cat's whiskers don't bleed if you cut them.
