User copies the target’s species, weight, type, ability, calculated stats (except HP), and moves. Copied moves will all have 5 PP remaining. IVs are copied for the purposes of hidden power, but stats are not recalculated. choice band, choice scarf, and choice specs stay in effect, and the user must select a new move. This move cannot be copied by mirror move, nor forced by encore.
