If Greninja uses Role Play, will it stay Psychic-type?

Question

Say my Protean Greninja uses Role Play on, I don't know, Intimidate Arcanine. Protean will turn Greninja into a Psychic-type Pokémon, but upon copying Aranine's ability, it will no longer have Protean. Because Protean is no longer in effect, will Greninja stay Psychic-type or revert to being Water / Dark?

Answer 1

Greninja will remain a Psychic type even if Protean is replaced.

The user's new type remains in effect until changed again or until the user is switched out; negating or replacing the Ability does not change the user back to their original type.
