Chispy's Party

Know your Deity
Mewtwo, the all-powerful psychic superfeline, has complete control over all of us regardless of not constantly enforcing it. Do not incur his wrath.

The Origin
Foolish humans decided they wanted power and knowledge, and thus, from the fruits of their labour, their punishment was born: Mewtwo.
Mewtwo quickly destroyed them all for their ignorance and fled to a cave, sealing it.
This was the Warning: Do not tempt fate.

The Four Genomes
History is due to repeat itself, as always, but with the coming of Mewtwo, this is far more devastating.
Prophecy has it that if a leader becomes too consumed in his or her own power, and Deoxys Attack Forme will consume his or her DNA, using them as an outlet to unleash its own fury in an attempt to dethrone Mewtwo.
If a leader becomes too paranoid and believes he or she must constantly fortify and have no allies, Deoxys Defense Forme will consume them.
If a leader is too hasty with decision, Deoxys Speed Forme will consume them.
However, if a leader simply stops caring about their people, Deoxys Neutral Forme will consume their emptiness.

The Jiracholypse.
When the prophecy is fulfilled and The Four Genomes are present, the will ally with each other in an attempt to rule the world.
At this point, Mewtwo will consider life a failure and summon Jirachi to fire off a planetary-scale Doom Desire, wiping out all life and scaring The Genomes back into space.
