A straight-up redeco of another toy in the line, Megaplex has a bio that presents him as a clone of Megatron. The design was an unused one that never got a chance to appear in the cancelled Generation Two line, but found new life in the Machine Wars line. Megaplex turns into a Lockheed-Martin F-22 Raptor. He was available exclusively at Kay-Bee toy stores in 1997.
From Japan's Operation Combination turbo team set comes the unfortunately named Discharge. This Autobot Micromaster turns into a firetruck, and has a robot design with a helmet that resembles that of a firefighter's. He was available only in a collected set with the rest of his teammates as a Japanese-exclusive in 1992. This drawing is from 2019.
The 1987 assortment was filled with gimmicks, including sets of Autobot and Decepticon clones. The premise was that the robot modes would be "identical", but each twin would turn into a very difficult vehicle or creature. In the case of Autobot clone Fastlane, he turns into a drag racer. In reality, the limits of toy design made it very easy to spot in an instant which clone was which. This drawing is from 2017.
