Neither Scizor nor Koraidon are "human shaped", they are just bipedal non-birds. They're no more "human-shaped" than an actual, irl, dog walking on it's hind legs. You are litterally re-inventing platos featherless biped problem here. Koraidon dosen't even use his front limbs for picking up things does he? There's probably a term for it but the best answer is what e621, actual furry site, would have tagged as "semi_anthro". Yes, in the proper dictionary defiition of the word that is still anthropomorphic, but so is the east wind. It's just about having human attributes at all.
Plato was attempting to describe a literal human while we are attempting to isolate humanoid characters, which for the purpose of Danbooru means characters with humanlike proportions. The comparison isn't even applicable.
Scizor might not have proper hands, but it's still distinctly humanoid. Cyberpunk Edgerunner's Rebecca wouldn't be any less humanoid if she had big robot drills instead of big robot hands; this logic applies regardless if the character is an anthropomorphic animal or not.
As for Koraidon, see asset #25141006, asset #25141018, and asset #25141007. Official images from both the anime and the game (plus a bonus BANDAI figurine) all show it with a humanoid figure. It has two arms with elbows that bend like a human's, it has two legs with knees that bend like a human's, it has hands with fingers and opposable thumbs, and if you ignore the stupid tyre embedded in its chest (which isn't even a disqualifying factor, see post #8518564) then the proportions of its limbs and torso are similar to a human's proportions. You might not like it, but it's completely in line with other reptilian furry characters.
