The pilot episode of Captian Scarlet, The Mysterons, showed the MEV from the Zero X traversing [excuse the pun, travers-ing!] the Martian landscape before Captain Black starts hearing voices. Above you can see the initial few minutes courtesy of You Tube. Presumably Zero-X is the only vehicle that connects Thunderbirds and Scarlet not to mention Project SWORD.
I'm not an expert on Zero-X in Captain Scarlet but there must be sufficient difference for Aoshima to have issued it, as a die-cast model, separately to to the Thunderbirds one. So what are the differences? Does Zero-X's main body feature in Captain Scarlet on TV or in the comics? I'm assuming that the Century 21 SWORD OX toy is based on the Thunderbirds version? Anyone know for sure?
On Wikipedia there is mention of lifting bodies in the New Captain Scarlet series on TV but I can't find anything on this anywhere else online.
Is is likely that there are collectors who specialise in the Scarlet Zero-X rather than the Thunderbirds one?
