Mega Drain (move): Difference between revisions

Mega Drain (Japanese: メガドレイン Mega Drain) is a damage-dealing Template:Type2 move introduced in Generation I.

Mega Drain is the second in a line of three Grass-type HP draining attacks, the other two being Absorb and Giga Drain.

Effect

Generation I-II

Mega Drain inflicts damage, and 50% of the damage dealt to the target is restored to the user. The amount of HP recovered is always rounded down. However, if this move deals 1 HP of damage, 1 HP will be restored to the user.

If Mega Drain breaks a Substitute, no HP will be restored to the user. If HP is restored to the user when its current HP is greater than its maximum HP, its current HP will be set equal to its maximum HP.

In Pokémon Stadium, Mega Drain will always miss if the opponent has a Substitute.

Mega Drain has 10 PP.

Generation III

If used against a Pokémon with the ability Liquid Ooze, the user will lose HP as well.

Generation IV and V

Mega Drain's base PP was increased to 15. If the user has the Big Root as its held item, Mega Drain saps 30% more HP than it would have normally. Big Root does not increase damage dealt. All other effects are the same.

As it does, the opponent becomes outlined in red and the beam turns red. The beam releases the opponent and goes back to Budew. Budew glows white when the beam goes back to it, and all of its injuries disappear.
