Takara's Micro Change line was one of the main sources for early Transformers toys. Not every Micro Change toy crossed the ocean to become a Transformer though. MC-19 Binocular Robo Scope Man is one of the exceptions; although a US patent was filed for this toy at the same time as patents for Perceptor and Blaster, it never saw release as a Transformer. It did see release in North America by at least one manufacturer - I know because I had one as a kid.

This results in a two-part custom project - first to customize a Robo Scope Man toy to what it may have been like as a Transformer (including character profile and tech specs), and second to do a modern version of this character. This modern version involved mixing and matching parts from the two Real Gear Robots binoculars figures that were released by Hasbro. One is blue and grey, the other yellow and black, so took the parts to make a blue and black one. The colour scheme is largely inverted from the original. Painted details and added chrome, also drilled holes in the fists to fit a weapon.

Transformers Universe Profile:

PARALLAX

Allegiance: Decepticons
Function: Surveillance

"I spy with my little eye, something that is...doomed!"

Profile: Unusual for a Decepticon, Parallax is patient - endlessly patient. While most of his team want to jump into action at the earliest possible moment, he sits and waits, observing and reporting, trying to find the perfect time to strike. When given a mission, he makes a plan and executes it, no matter how long it takes. If it takes him days, weeks, or even months, he will do what he has to do.

Abilities: Parallax has a complex and sensitive suite of advanced optics that he uses to surveil and spy on his targets. He has an array of Infrared scanners, X-ray sensors and other systems that allow him to see things that no one else can. In battle he uses a solar-beam ion ray powered by an internal light plasma system, using solar radiation to recharge it.

Weaknesses: Because his focus is so intense, Parallax can sometimes miss the trees for the forest, so to speak. He devotes so much attention to seeing hidden things that are far away that he often misses the obvious things right next to him.
