Master Crystal

The Master Crystal is a crystal that was found by Dr. Neo Cortex from a cave where he fell to after his last encounter and failed battle with Crash Bandicoot on his zeppelin outside Cortex Castle on Cortex Island.

Cortex brought it back to the new Cortex Vortex but he still needed 25 more Crystals to harvest the Master Crystal's energy. He planned to use it's power to turn the entire population of Earth to mindless slaves of Cortex.

After the Cortex Vortex was destroyed, it is not seen or mentioned again in the game. It has not been mentioned or seen since and as such it was probably destroyed during the impact of the Cortex Vortex.
