It originated as an official meme inspired by the numerous meme coins on o1 Launchpad that resemble "Basecat", an orange cat wearing a blue hard hat. It features bouncy, playful and vivid animations, chaotic yet lively group scenes, and approachable simple hand-drawn expressions. With a fun, relaxing and highly recognizable style, o1 doll fully embodies the casual, creative and co-building atmosphere of the o1 ecosystem community. ## Design at a glance A smooth, nesting-doll body in plain white with a visible seam at the waist The builder signature carried over from Basecat and the o1 Launchpad meme scene A simple black marker face, arms and legs drawn straight onto the doll ## Views o1 doll front view showing the smiling stick figure and blue hard hat The full character: smiling face, outstretched arms and planted legs, with the hard hat sitting over the drawn head. o1 doll side view with the hard hat and drawing wrapping around the profile In profile the drawing wraps around the doll, so the hat and limbs read as one continuous line across the surface. o1 doll back view: a plain white Matryoshka doll with no drawing The back is left completely blank. The character lives on the front face only, keeping the silhouette clean. ## Poses o1 doll in its neutral standing pose The neutral resting pose. Arms out, legs apart, calm smile. This is the default reference for the character. o1 doll in an action pose, waving with one arm raised and legs kicked out In motion the limbs break out past the edge of the doll, with drawn hands and feet, one arm waving and legs kicked out. This is where the bouncy, playful animation style comes from. A group of six o1 dolls in descending sizes, all waving Nesting-doll sets scale from large to tiny, each one waving with a slightly different expression. Group scenes are deliberately chaotic and lively, mirroring the community itself. ## Where it comes from o1 Launchpad hosts a large number of community meme coins built around "Basecat", an orange cat in a blue hard hat. The o1 doll takes that same builder hard hat and puts it on a stick figure, turning a recurring community joke into an official mascot. The nesting doll gives the character a group format by default. One doll is a single builder, a full set is the community, and the sizes make crowd scenes easy to compose without redrawing the character.
