Fiction

G-2 comic

In August of the year 199X, the Autobots and the Decepticons detected the presence of forestonite on the planet Earth. Decepticon leader Megatron and his Cyberjet warriors Hooligan, Skyjack, and Space Case attacked Japan in search of it, but were repulsed by the Autobots Optimus Prime and Electro. With the Decepticons defeated, Optimus Prime swore to defend the Earth and its forestonite with the aid of the young boy Junpei. The New Battle!!

TransTech

The TransTech CEO of C-Kar Technologies, Ego, had sixteen kilos of forestonite in his personal collection. This was supremely impressive, even to his corporate rival Bulletbike, who, despite his vast resources, had to substitute solitarium for the element in some of his corporation's experiments. Learning that Ego not only had a sizable amount of forestonite, but also had the gall to put it on display, enraged Bulletbike to no end. I, Lowtech

Notes

• No, seriously... the manga basically says nothing specific about forestonite. It's on Earth and the Decepticons want it. That's it. We don't even get to see it in action... or even if it's a solid, liquid, or gas. As far as ill-defined super-power-sources go, this is the king.
