A: While I find that as equally as important as the visual and character design, I don't think that is the main issue here in most Pokemon designs. You could argue that no matter how well a character fits (by design and so forth) within a fictional universe, if they are not written well and visually designed to stand on its own, it would fail. My point is best exemplified by looking at the Pokemon DLC legendaries:
Man, what a polarized reaction these guys received, arguably even worse than the dog duo and Eternatus! But why? The main culprit is not having appealing visual and character designs, rather than fitting into the Pokemon universe or their potential for lore. People were cringed by Calyrex's unappealing proportion exaggeration, Urshifu's major jump in design from Kubfu, Urshifu's so-so color schemes, and excessive ornate details that do not really contribute meanfully.
I understand the reasoning behind the designs and we get that the Galar legendaries represent the medieval British royal court and myths (Calyrex = A king with a scepter/crown, Zacian = Morgan de Faye/Excalibur/ sword-based knight, Zamazenta = King Arthur/Wynebgwrthucher/shield-based knight, Urshifu = royal archbishop/head of Christianity in the medieval era/performed rituals/sacrements to purge evil)
, but can it be executed better?
(
(my images; were they trying to aim for a monochromatic cool-grey design with purple undertones and for contrast/complimentary colors, they added yellow-mustard accents? Where's the color differences for Urshifu's formes?)
Which leads to to my next subpoint: Zamazenta-Crowned can be designed better and retain the faithfulness of its theme. I'l give it a shot:
I did this in 45 minutes, and in lower quality in which I usually draw. Having a shorter cape, relocating the side shield parts, lightening the blues, simplfying some of the decoration on the shield, and darkening the yellows for improving the color scheme, and actually making the Behemoth Bash actually magneta (not orange) like how his name is based on I think makes it somewhat an improvement. It's not perfect, but its a start.
