Dusknoir have long been renowned for being able to withstand countless attacks before being knocked out, for they carry more souls at a time than Spiritomb. These souls, however, are not their own; the reaper cloth which makes Dusclops evolve carries with it the sacred duty to ferry souls to the underworld, and even trained Dusknoir will never shirk this obligation.
Dusknoir do not, however, feel any responsibility to complete this task in a timely manner, reasoning that if a soul could spend decades on earth it can wait a few days or weeks to reach the afterlife. Dusknoir's roundish shape is the result of carrying so many souls at a time, and no one has ever seen a thin Dusknoir, for the souls are never released all at once. Humans and pokemon alike are reluctant to disturb those involved in the journey of souls to the next life, and Dusknoir soon realized that if they were always involved in said journey, then they could become untouchable.
Yet all make an exception to this rule when in the confines of a pokemon battle, reasoning that any Dusknoir willing to enter one has renounced its traditional immunity, and Dusknoir are fiercely competitive and despise losing. Before major matches, a Dusknoir will accumulate even more souls than usual, and use the power of assembled souls to protect themselves from most types of harm. There is thankfully no risk to the souls involved; at worst, a particularly strong attack will eject them, leaving them to typically drift around the battlefield until the Dusknoir scoops them up again and resumes the fight. However, a few spirits unwilling to depart have used this opportunity to escape and remain in this world as ghosts for as long as they can avoid Dusknoir and exorcisms.
