Waterfall (Japanese: たきのぼりCascade Ascent) is a damage-dealing Template:Type2 move introduced in Generation I. It was the first move to gain HM status in a generation after it was introduced, doing so in Generation II.
Allows players to climb waterfalls. Note that in Generations II and III, the HM move Waterfall is not required to go down waterfalls, whereas the first two games of Generation IV requires the HM. However, in Pokémon Platinum, the HM is not required to surf downwards.
