Deviation O-069 is a self-made quadrupedal war beast plush doll, approximately 2.5 meters tall and 4 meters long, constructed from cardboard and coated with colored crayons. The item appears as an upright-walking carnivorous dinosaur, with its body assembled from multiple layers of folded cardboard, covered in saturated crayon coatings of blue-green, orange-red, and other colors. Hand-drawn "scale" patterns are visible on its abdomen and limbs. A distinct saddle structure is present below the neck, presumably designed to carry O- 067.

The overall craftsmanship of the item is cruder compared to O-067, with joints repeatedly wrapped in transparent tape. A cardboard seam on the abdomen appears to have been opened and closed, leading researchers to speculate that a sound-producing device was once placed inside. The characters "69" are written in crayon on the outer side of the right hind leg, which researchers used to name the item.

O-069 possesses independent mobility, capable of autonomous walking, turning, and emitting low growls. It can also detect nearby vibrations and sounds. When moving, the item produces noticeable cardboard friction sounds and rhythmic "stomping" noises. Researchers describe its movement as "heavy yet cheerful."

The primary Deviation Traits of O-069 are its unexpectedly high load- bearing strength and charging impulse. In Common Detection, its cardboard structure can withstand static pressure equivalent to kilograms without deformation. In charging experiments, its forward Speed can reach meters per second, sufficient to penetrate standard Brick Walls without significant damage to itself. When the item detects O-067 Entering within approximately 5 meters, its action Mode switches from the Default wandering state to a "mount preparation" state-lowering its head and neck, opening the saddle, and actively approaching O-067. Once the "carrying" docking is complete, O-069 immediately enters a high-speed charging Mode, with its attack objectives primarily being targets judged as "enemies"
