Crash Bandicoot 2: Cortex Strikes Back
They were first discovered by Dr.Neo Cortex after he fell into a cave (prior to his previous fight with Crash), and found the Master Crystal.N.gin told Cortex that they also need 25 "slave crystals" in order for their newest plot to be in effect. Cortex then used Crash to collect the remaining crystals, by traveling into 5 tunnel-like caves which will lead him to the crystal he needs. In gameplay Crash must traverse through obstacles and hazards to obtain the crystal when returns succesfully, he will pull it out of his pocket and levitate over his head into the Item Hub above him. Once Crash obtained the right amount of crystals, a Boss should be awaiting him to progress to the next level.

Crash once again had to collect the crystals from Cortex and a new threat N.Tropy and Uka-Uka, for they were using a new device to travel back in time and collect the crystals before Crash was even born. Aku-Aku used the machine to send Crash and Coco to retrieve the crystals before Cortex and his henchmen had the chance. In gameplay Crash and Coco would follow the same procedures as it's sequel, which will lead to them engaing in a Boss Battle to proceed to the next area.

Crash Bandicoot: The Wrath Of Cortex
Another quest for the crystals took place, when Uka-Uka set free an evil group of evil masks known as the Elementals for Cortex's latest expirement. Aku- Aku warned Crash and Coco about this threat and said they could only be put back into their slumber with the work of 5 "Elemental Crystals". Unlike it's past series, Crash is the only one who could enter the Boss Battle.

The Crystal's were first founded by Cortex after he and Crash went into a brawl, and landed into a cave. They both couldn't let go of the crystal, which to them being stuck together throughout most of the game. They did became a necessary requirement, when Cortex discovered how to travel to demiensions. In this game the Crystal's were no longer obtained through warping through levels, but from traveling to place to place.
