As people who know me know, that my style is realism-approached and rather reality-based esque, (or just semi-realism for short, I got no better terms to accurately pinpoint what I mean) in a way. That's how I choose to stylize mobians/seedrians.
Sonic characters tend to have noodly limbs, oversized shoes and gloves and just very exaggerated features in general. Heavy stylization, so to speak.
Seedrians have the anatomy, that of a berry and a mushroom, with my rules.
I give mobians actual muscles, human-like limbs, proportionate head-to-body & hand/feet ratio and also realistic features like folds and visible lips/chins. What does that have to do with the description?
Well. Mobians used to be humans back then. If you're familiar with my Human/Anime storyline, you actually know a bit already.
Humans tested animalistic features on other voluntary humans, until it became such a heavily-demanded modification toward the human genes, that the population started to become more- and more animalistic, to a point they're here today, being mobians.
Human, to Kemon, Kemons, to Anthros, Anthros, to Mobians. That's the progression, their evolution went. They took a step back on purpose. Basically pressed the reset button, on all the developments, humanity has made so far toward them, going back to tradition, billions of year ago.
Mobians have humanoid bone-structures, muscles, features like carnivore teeth more humanized, snouts turned to muzzles, etc.
The generation goes as follows;
Gen-1 (anthro-like)
Gen-2 (prototype-mobian, some flaws in their genes and physicality)
Gen-3 (Normal mobians with lesser-issues and normal blend between human and an anthro, basically no sicknesses but still could be feral.)
Gen-4 (Most current, sought-after generation, freshly created in evolution, perfect blend between human and animal-genomes, causing naurally-beautiful faces & bodies to occur aswell as 0 issues in their genes nor any mutations popping up.)
