 ### Physical Description
 
-Upright grizzly-style bear in three-quarter view, heavy brown fur (darker on the back, lighter muzzle/belly), weight on the back leg, free arm reaching forward with big hooked claws — confrontational, not cuddly. Entire left arm replaced with a chunky steampunk / retro-futurist prosthetic (silver plates, exposed brass gears at the shoulder, pistons, rivets). **Red fez** with a **yellow hatband** and a **black tassel** off the top — absurd court-jester energy against the grim claws and metal.
-
-Style: bold black outlines, flat cel shading, early-browser RPG illustration (*Adventure Quest* lineage). For the movie: flat color, readable at small size, slightly goofy menace.
+**Mandatory identity (always visible — fez + mech arm are not optional):** red **fez** (yellow band, black tassel) on head; entire **left arm** is brass-geared **steampunk prosthetic** (silver plates, exposed shoulder gears, pistons). Lean upright cartoon bear, brown fur, **short blunt snout** slightly upturned — **match `pfp/ubear/ubear_forme_design_ref.jpg` snout length exactly** (not elongated, not wolf-like). Biological right arm: fur, long black claws. Flat cel *Adventure Quest* style.
 
 The Twitch profile shots are whatever face he wore in chat; the **Ubear forme** is the hero design when a single silhouette is needed.
