Hyper is corrupted with both red and blue phazon, He's the expert phazon warrior.
He has the ability to create his own red or blue phazon.
Both phazon got into his heart, painfully corrupting it with red and blue phazon, He'll be invulnerable to everything harmful.

So Hyper uses Phazon Power on punching bag.
Special Thanks to StrikerTehPhazonEmperor for corrupting Hyper the Fox.
