Torrent (Ability)

Torrent is an ability possessed by Water type animals, most typically starter animals of a region.

In Battle Use
Animals with the Torrent ability have their Water type attacks powered up to 150% when their health is at 30% or less.

Speculation
This ability may have derived by the full power animals would deliver within a battle while facing off against an opponent. Victory can only be declared for the stronger animal and either fleeing/fainting would result in a loss; thus, animals must fight with their true power.
