Somehow full size Cassette Robo returned... Filed 1984-10-31, around the same time as many other canceled Micro Change items. This time, he was upgraded with a working radio. Also another variation was shown as well. Invented by Takashi Matsuda. JPS6180090U

Around the same time Daishirou Shibukawa was working on the unreleased dino triple changers, he also invented this unreleased mini dinobot. The T-Rex details resemble Grimlock, but the transformation and robot mode are totally original. Filed 1985-01-31. JPS61130288

Patent MC-20 Micro Scope aka Perceptor. This patent is for the body tube/shoulder cannon and how it was designed to keep it from breaking. (As a kid, mine ended up broken anyway sadly.) Filed 1984-10-11. Invented by Haruki Saito. JPS6167797U

Last but not least, the patent for Vortex was filed on 1985-05-14 as well. Lots of small differences from the final version, like the torso rotating, a different feet transformation, and the tail parts flipping forward in robot mode. Invented by Daishirou Shibukawa. JPS61188794U

The patent filed on 1985-05-14 for Swindle is similar to the final version, except that the connector peg to form Bruticus's arm folds out differently and does not use Swindle's head. He is shown attached to the prototype Combaticon tank torso. Invented by Daishirou Shibukawa. JPS61188795U

A patent for early versions of Blast Off and Brawl was filed 1985-02-16. They look very different from the final versions, including how they transform. The patent shows how Blast Off would peg into Superion's torso. Invented by Kohjin Ohno. JPS61139283U

Here’s the Macross Valkyrie from Fight or Flee. The other Paradronian looks rather startled by his presence! Interestingly neither Valk is the early Jetfire model (no armour) so it isn’t a case of pulling an existing model off the shelf, rather someone was deliberately inserting Macross Easter Eggs!
