designer Charles Eames. Flag, a figure painted as a nation's flag. Horror, a figure with a theme based upon a well-known horror film, or other source in the horror genre.

Animal, a figure which depicts an actual animal. Artist: two figures, each designed by a visual artist. Hero: this category was introduced in series 21, and consists of superheroes from DC Comics. Bearbricks are most often sold individually in "blind box" assortments, in which figures are packed in small boxes, and the only way to know which particular figure is inside a particular box is to purchase and open the box. The box states the frequency of each figure in percentages: Basic, 14.58 percent; Jellybean, 11.45 percent; Pattern, 11.45 percent; Flag 9.37 percent; Horror, 9.37 percent; SF, 10.41 percent; Cute, 13.54 percent; Animal, 8.33 percent; Hero, 7.29 percent; first Artist, 4.16 percent; and second Artist, 1.04 percent. While many retailers sell Bearbricks in blind boxes, each for the same price, other retailers calculate the frequency of the figures, and sell them at prices that vary accordingly; in this instance, the Basic figure would be the least expensive, as it occurs most often in a case, and the second of the two Artist figures would be the most expensive, as it occurs least often in a case. The figures most valued by collectors are "chase" figures, which are unannounced and not shown in advertisements or on the box alongside other figures in the series. Collaborations Many contemporary artists and designers from Asia, Australia, Europe, and North America have designed figures. Designing a Bearbrick figure means creating a design scheme, or deco, for the standard mold. Contributors range from visual artists such as H. R. Giger to illustrators such as Pushead, graffiti artists such as Stash, and fashion designers including Karl Lagerfeld, Vivienne Westwood and Ivana Helsinki. As a result of their limited production, and the participation of artists, Bearbricks are generally considered designer toys. MediCom also produces Bearbricks outside the regular release schedule of the basic figures. For example, a Kill Bill Bearbrick was created in 2003 as a promotional piece for customers who purchased pre-sale tickets to see the film Kill Bill Volume 2 in Japan. Another Kill Bill Bearbrick,
