Heart Spheres

Heart Spheres are items in the game Pokémon: Universal Defender. Giratina uses them to power the bosses throughout the different dimensions, and to power himself.

History
Heart Spheres are spheres of energy that come from the Original Form power source. They are used to give an artificial life force to Pok&eacute;mon. Though the Heart Spheres can give the holder an additional life and unstoppable power, they curse the holder, and make them evil. Giratina used this to his advantage, enslaving the Legendary Pok%eacute;mon. Because the Heart Spheres come from the Original Form power source, any Pok&eacute;mon that uses them is also mutated into their original forms, in addition to being strengthened and turned evil.

In the Games
Giratina provides three Heart Spheres to each boss, and six to himself (three the first time he is battled, and three the second time). After several of the boss's attacks have been dodged and several of the summoned minions have been defeated, the boss will expose a Heart Sphere. If the Heart Sphere is destroyed, the boss comes closer to defeat, but otherwise, the Heart Sphere will fire a very damaging blast. If the Heart Sphere does blast, it does not damage or harm the boss in any way. After all three Heart Spheres are destroyed, the boss is defeated.
