The prototype Space Vixens gun named either ‘The Bliss Disruptor’ or 'The Teslon Atomizer’. Wielded by the Felicity Bliss character of the Space Vixens line, it never really saw production from Sixteen 12 Collectibles Ltd beyond this one prototype.
Which is a sincere tragedy, because everything—from its chrome barrel to its polished bakelite-esque trigger guard— is an absolute masterpiece in raygun design.
They had two Space Vixens statues planned in addition to this, Captain Felicity Bliss and Tatiana Rockettov, both of them exquisite atompunk/dieselpunk works of art. Unfortunately only 500 Felicity statues were released. Tatiana Rockettov never saw full production either.
