For the Irken, yes. But I always thought they could put the PAK on someone/something else and it would carry on like normal. Except the personality would be confused. XD You're welcome!
Just think... If that works... You could get an Irken stuck in a chicken's body. XD If only we knew for sure, but I'm having it so PAKs can use anything, because that can be used in a duckton of ways.
