Energon crystal

Energon crystals are a substance from the Beast Wars portion of the Generation 1 continuity family.

Energon crystals are a powerful raw form of energon with the drawback that they are also extremely unstable. They emit radiation which can cause stasis lock in Transformers and is even potentially fatal to them. Energon crystals are highly explosive, more so even than Energon cubes; they can be detonated by blunt impacts, fractures and even sudden temperature increases.

Fiction

Beast Wars cartoon

Megatron led the Predacons to Earth with the hope of finding Energon, but the crystals were so powerful, the radiation from them threatened to extinguish the sparks of the Predacons and Maximals. To avoid death, both factions took beast modes to allow them to function outside their respective vessels. Beast Wars (Part 1) Sufficiently large deposits, such as the one the Predacons uncovered on a mountaintop, produced enough radiation to make it hazardous to switch to their robot modes. Beast Wars (Part 2)

Terrorsaur later found a mountain filled with extremely unstable energon crystals, causing it to float in the air. Although the mountain was destroyed by Optimus Primal and Rattrap, it did empower Terrorsaur enough to defeat Megatron…for a few nano-kliks. Power Surge An experiment by Megatron to increase the power of the crystals appeared to fail, but as this later turned out to be part of a ruse, it's unclear if Megatron had any success in his work. Victory

An exploding deposit of Energon crystals blinded a group of Energon-mining Maximals, and contaminated them with Energon radiation. Dark Voyage Exploding crystals also proved effective in extracting Starscream from Waspinator's body. Possession

When the Vok, who seeded the energon on the planet, discovered the presence of the Maximals and Predacons, they attempted to destroy the planet by detonating the energon crystals with the Planet Buster. Optimus Primal managed to destroy the weapon with a stasis pod reconfigured by Tarantulas to serve as an escape pod, but the initial heatwave and subsequent Transwarp explosion caused the energon crystals in the area surrounding the Axalon and Darksyde to detonate or convert to energon cubes. Coming of the Fuzors (Part 2) This allowed the Maximals and Predacons to stay in robot mode for prolonged amounts of time without the effects of energon buildup.

Some crystals survived the destruction, Megatron was able to locate a cave full of them, but Tarantulas managed to manipulate events so he could use it as his lair. Tangled Web A small cluster of crystals near Rampage's stasis pod was destroyed during a battle, blasting the participants in all directions. Bad Spark Another cave containing crystals was destroyed by Inferno in a moment of insane self-destruction. The Agenda (Part 2) An abundance of them were located on the ocean floor near the Nemesis; however, they were presumably all destroyed by the explosion when Depth Charge killed Rampage.

• Scuba used the crystal's power to repair the environmental damage caused by the Predacons.
• Megastorm gloated to himself that with the power of the crystal, he would finally overcome Galvatron...only for his brother to steal the crystal right from under his nose.
• Cheetor, having used the crystal to become the most powerful of all Maximals, was promoted to Supreme Commander. However, he couldn't handle the responsibility required for the post, and ran away after only three days.
• Guiledart decided not to use the crystal right away. Believing that there is still a long time until the war ends, he kept it around as a future trump card.
• Optimus Primal used the crystal's power to defeat the Predacons once and for all, saving the universe!
• Megatron took the crystal and set out to defeat his eternal nemesis, Optimus Primal.
• Star Upper wanted to become strong under his own power and didn't use the crystal for anything.
• Artemis, blissfully ignorant of the crystal's power, found it really pretty and took it home to decorate her room with it. Duel Fight Transformers Beast Wars: Beast Warriors' Strongest Decisive Battle
