Rumor has it that only 100 of these were made, and only 24-26 are accounted for. These were never sold to the public. (We're not talking about cheap bootlegs.)

Two major variants exist: an "L"-slot rocket firing mechanism and a "J"-slot mechanism, based on the backwards shape of those letters.

Almost all of the prototypes are unpainted, blue figures. One version is known to have yellow legs.

The "L"-slot missiles have 4 distinctive "ribs," whereas the "J"-slot version has 8 distinctive ribs. Since this projectile separated from the figure, it's not necessarily paired with every prototype; some were lost.

None of the figures have a copyright stamp on the leg, like the regular release of this figure (which did not have a working, firing rocket).

Each prototype figure was loose, however, one version was shown carded at a Toy Fair expo.

Tomart's Action Figure Digest #20 has an authoritative write-up on the further back story.
