Does Transform copy a target’s original or current ability?

Question

Let’s say I’m in a battle, and for some reason, my opponent’s Audino has copied my Gengar’s Cursed Body with Entrainment. If I switch out my Gengar for a Ditto, will my Ditto gain Cursed Body if it transforms into the opponent, or will it be stuck with the original ability, Healer?

Answer 1

It will copy the current ability.

Imposter/Transform work the same and copy the opposing Pokémon's current ability and current stat boosts among others. It will not copy the previous ability if it has been changed.
