The powerful crysmag metal is a substance found only in the sunken continent of Lemuria. When energy is directed against it, it absorbs, magnifies and redirects that energy, projecting it outwards.

As part of his final plan for the destruction of Earth, Decepticon emperor Scorponok set up base in Lemuria beneath the Indian Ocean. Mining crysmag ore, Scorponok had it forged into metallic “Death Towers,” which erupted from beneath the Earth in four key locations around Earth – Canberra, Australia; Santiago, Chile; Washington, D.C.; and Cairo, Egypt. Unwitting Autobot attacks on the towers only proved to them that such a strategy was foolish, while Scorponok outfitted the towers with induction boosters, causing them to draw in the Earth's energy and redirect it to a satellite he had installed in Earth orbit.
After a fifth tower was raised in the South Pole, Scorponok pulled back to the North Pole, where he raised a final crysmag platform. While in battle with Fortress Maximus atop the platform, he had the satellite direct the energy it had absorbed into it, creating a loop that would tear the Earth apart. Thankfully, a power boost courtesy of the united energy of the entire Autobot army allowed Maximus to counter the energy flow with the Master Sword – the feedback destroyed the satellite, and presumably the Death Towers as well.
