Energon crystal
- Energon crystals are a substance in the Beast Wars portion of the Generation 1 continuity family.
Energon crystals are a more powerful form of Energon when compared to cubes. However, they are extremely unstable, emiting radiation which can be fatal to Transformers with prolonged exposure, and risk detonation with temperature increases.
Fiction
Beast Wars
Megatron lead the Predacons to Earth on the hopes of finding Energon, but the crystals were so powerful, they radiation from them threatened to cause 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
Terrorsaur later found a mountain filled with extremely stable Energon crystals, causing it to float in the air. Although the mountain was destroyed by Optimus Primal and Rattrap, it did empower him enough to defeat Megatron…for a few cycles. Power Surge
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 it 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 sorrounding the Axalon and Darksyde to detonate or convert to Energon cubes.
