Showcased here is one of only two known complete Silicon hardcopies. Originally planned for release in the infamous 4th series line-up, the chiseled looking character was denied time on retail pegs and never reached full production status. Other characters that reached the three dimensional prototype stages include: El Dorado, Manbat, Rocket Man, Shockwave, Quadrex, and Power Plus versions of Batman, Cyborg, Firestorm, and Superman. Like most Kenner hardcopies from this timeframe, Silicon is cast in green urethane referred to as "dynacast". This particular Silicon hardcopy, along with the other complete existing example, a Kenner archive sample, surfaced as part of an infamous find brokered by The Earth Collectible Toy Mall in September 2004. The only other unpainted hardcopy around that I'm aware of aside from the two complete examples is an additional unpainted head, which was uncovered in 2005.
Hardcopies are produced using a silicone mold (this mold is created from the orginal wax figure sculpting). Once it is removed from the mold it may serve a number of purposes. It might remain unpainted and ultimately be used during the creation of the steel production mold. When used for this purpose, the hardcopy is referred to as a "tooling master" or "tooling hardcopy". Silicon *did* make it farther than the hardcopy stage. A head mold, similar to the Manbat head mold seen here, exists to support that statement.
The somewhat unique construction of this particular hardcopy partially hinders complete assembly of the figure, at least where the head and thighs are concerned. The head features a cylindrical peg terminating in a circular disk protruding from the neck area. A similar shaped peg is also located on the right inner thigh. In contrast the left leg possesses a depressed, circular region on the inner portion. The plastic baggie this hardcopy was stored in states "cleaned for proto mold", indicating it was to serve in the generation of a protomold (Kirksite mold) typically used to make protomolded figures. I use the collector generated term "internal first shot" elsewhere on the site, but the terms protomolded figure and internal first shot both refer to the same thing. The torso, arms, and lower legs all exhibit the standard attachment points for a metal dowel. The other complete Silicon and the extra head both exhibit joint qualities found on most other hardcopies. In other words, the joint areas of the head, arms, and legs all have holes to accomodate metal dowels.
Silicon is absolutely a dynamite character. The chiseled look of nearly all parts of the character give it a unique appearance. Based on conceptual artwork from a Kenner file photography slide, it appears he was planned to be cast in translucent plastic affording a view of his internal mechanism. Based on the way the arms pivot, Silicon was likely slated to have an arm raising power action similar to that found on Wonder Woman. Ah, what might have been if only the line lasted for an additional year!
