Secondarian (Ability)

Secondarian is an Ability. It is the signature ability of the Puffpus line, and is original to Pokémon Beryl.

Effect
Immediately before using any move (except Struggle), a Pokémon with Secondarian as its Ability will change its primary type to be the same type as the move it is using. However, unlike Protean, a Pokémon with Secondarian will keep its secondary typing, in the case of the Puffpus line, Poison. The Pokémon will become a dual-type Pokémon with the move's type as the primary type and Poison as the secondary. For example, if the move used is Dark Pulse, Sauerpus would become Dark/Poison.

In all other aspects, the ability is identical to Protean.
