ZX Crystals

ZX Crystals are powerful crystals which are extremely rare.

History
When the villain Hive destroyed Makuhero City, he took a very large portion of the Hero Factory with it. Mr. Makuro was one of the casualties. In his final moments, Mr. Makuro gave 2 ZX Crystals to Zib. Zib would go on to put these crystals onto two Heroes. Fuse and Magnus.

Usage/Abilities
These crystals are capable of powering up the user to an almost frightening degree. The crystal uses the ZX energy inside it to power up the user. This powered-up state is referred to as the ZX Form. Though the powers of this form are great, it drains the user's Hero Core much faster if overused. Humans are also capable of using this as well, but to no drawbacks.

Trivia

 * The 'ZX' title is based off of the game Mega Man ZX, which TempestDevil plays often.
