Sizes range from small figures a few inches tall (about 3.5–3.75 inches) up to large, display-scale models measured in feet. Example listings include figures 25.7 inches long, 39 inches long, and others described as more than 3 feet long.
Most figures are made from plastic, commonly specified as "Plastic" or ABS (Acrylonitrile Butadiene Styrene).
Some figures include electronics and list specific battery types (for example, one listing shows 3 LR44 alkaline). Many other toys in the selection are battery-free.
Mechanics vary by product. Some use a smash-and-dig format with slime, sand, or fizzy compounds to uncover pieces. Others use a capsule or incubator-style system where you add "DNA" powder and liquid, shake to develop the figure, and then use the container as an incubator-style display.
Deluxe figures emphasize lifelike sculpting and display features such as extensive articulation (for example, up to 17 points), glass-style eyes, a posable tongue, wired tails, and movie-accurate detailing for collector display.
