On the turn Doom Desire is selected, this attack will do nothing other than state that the user has chosen Doom Desire as its destiny. Two turns later, Doom Desire will do damage against the target.
The damage dealt uses the Attack stat of the user and Defense stat of the target at the time of move selection (not at the time the attack actually hits; if the target is switched out, the attack will hit its replacement but the damage is based on the original target Pokémon). Damage dealt by Doom Desire does not have a type; it is not affected by type effectiveness, does not receive STAB, and can hit Pokémon with Wonder Guard.
Doom Desire fails when used if the target is already set to be hit by Future Sight or Doom Desire. Doom Desire can hit the Pokémon that used the move. If Doom Desire misses, the miss will not occur until the third turn, and the game will display that the move "failed" rather than "missed".
In Double Battles, if the intended target has already fainted by the time the attack is foreseen such that there is no target, Doom Desire will redirect the same as other moves do (e.g., target the other opponent instead). If there is no target at the targeted slot by the time the attack is due, Doom Desire will fail without further notice.
Its damage is not increased by Life Orb. A Pokémon holding a Focus Sash can survive Doom Desire.
Generation V onward
Doom Desire's power changed from 120 to 140, and its accuracy changed from 85% to 100%.
Doom Desire now calculates its damage when it hits rather than when it is selected. Doom Desire uses the user's Special Attack and the hit Pokémon's Special Defense at the time damage is dealt.
It now inflicts damage as a Steel-type move; therefore, it is affected by type effectiveness, can receive STAB, and will not necessarily hit through Wonder Guard. If the user has Normalize or was affected by Electrify when Doom Desire hits, it hits as a Normal- or Electric-type move respectively (regardless of whether this was the case when the move was used); however, it cannot be redirected by Lightning Rod even if it is an Electric-type move. Doom Desire can now land a critical hit.
In battles with multiple opponents, Doom Desire may now target a slot without an active Pokémon. (If a Pokémon occupies the selected slot by the time the attack is due, Doom Desire will attack as intended.) If there is no target at the targeted slot by the time the attack is due, Doom Desire will still fail without further notice.
A Pokémon can now endure Doom Desire with Endure or Sturdy, in addition to the Focus Sash and Focus Band. Doom Desire disappears with no message if it would hit the Pokémon that used the move.
Jirachi's body starts to glow silver to charge the attack. Then, it starts to glow a very bright light and it flies up and raises the opponent into the air and it leaves behind a streak of white light, like a comet. It then lets off pulses of a multitude of colors and soars farther into the sky. Once it is high enough, it lets off an explosion. Finally, a meteor shower is released from the explosion.
Jirachi's eyes glow white and it releases a blinding white light from its body. After a while, multiple orbs of energy form in the sky. The orbs of energy then form into streams of energy and shoot into the opponent. When the stream of energy makes contact, it explodes.
