Effect

Generation I

Mega Drain does damage, and up to 50% of the damage done to the opponent is restored to the user. However, if this attack does 1 point 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 Stadium, Mega Drain will always miss if the opponent has a substitute.

Generation III

In Generation III, if the opponent has the Liquid Ooze ability, the user takes damage instead.
