Fiction

G-2 Comic Bom Bom 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

Wings Universe

Wings Universe is based on the Generation 1 cartoon, but deviates from it in cosmetic ways and continuity points.

The Predacon general Sky-Byte discovered a way to refine forestonite for sinister purposes! Normally just a sub-par fuel source, the true potential of forestonite can be unleashed by bombarding it with high-energy particles. Thus charged, forestonite can be used to give Transformers assorted powers that others would consider to be supernatural, although this comes at the cost of an impossibly garish color scheme. Generation 2: Redux

Sky-Byte presented large amounts of forestonite to Jhiaxus. A Flash Forward, Part 2 Jhiaxus utilized the forestonite, blueprints stolen from Quantum Laboratories on Earth, personality components procured by the Battlechargers from Cybertron, and the forced help of Nebulan scientist Hi-Q to create a "second generation" of Cybertronians. A Flash Forward, Part 3 Jhiaxus also studied the forestonite provided by Sky-Byte to create an energy that could suppress forestonite-based abilities. A Flash Forward, Part 4

Mutinying against Captain Cannonball in order to seize control of the Star Seekers for her Decepticon cause, Flamewar hurled a vial of forestonite into Cannonball's chest so that her new ally, the infamous Decepticon Starscream, could take over Cannonball's body. Later, Ferak utilized forestonite on the Tidal Wave in order to enable the Star Seeker warship to escape orbit of Starscream's prison, a planetoid almost completely surrounded by black holes.

Notes

• No, seriously... the G-2 comic 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.
