A Solar Flux is an event that occurs when all the planets in the Solar System align. The stellar energy from the flux can be preserved by using the Power Crystals or Gems scattered throughout the world. Cortex needed to collect the crystals so he could use the stellar energy to power up the Cortex Vortex in Crash Bandicoot 2: Cortex Strikes Back and N. Sane Trilogy. However, Doctor Nitrus Brio eventually harnesses the force with the gems provided by Crash Bandicoot to destroy the Cortex Vortex space station.
- The Solar Flux is never mentioned as such in-game. It is only referred to as a force or planetary energy. However, the name of the event was revealed in the instruction manual for the original Crash Bandicoot 2: Cortex Strikes Back.
