The sad fact about Generation 1 is that, while it was
mostly based on existing molds from Takara's
Diaclone and
Microchange lines, some of the toys never made it over to the UK, even if they
were released in the US. Perceptor is one such model. In many ways, you have to wonder about the thinking behind bringing Perceptor into the TransFormers brand - sure, he transforms... but into a
microscope (and,
loosely speaking, into a kind of tank thing). Great disguise, certainly, and one that was re-used for Scalpel (aka The Doctor) in Revenge of the Fallen... but in a line of toys that transform from robots into cars, planes, etc, Perceptor stands out as something quite irregular.
Naturally, Soundwave also originated from the Microchange line, as did Blaster... but they worked somehow... A Microscope just seems incongruous.
As a character, Perceptor was fond of big words. His big moment in the animated movie came when, having seen the Decepticon forces approaching Autobot City, he announced "A cursory evaluation of Decepticon capabilities indicates a distinct tactical deficiency," quickly translated by Springer to
"We're outnumbered." You could almost see him getting on
very well with Shockwave, in other circumstances.
