Well Wukong was able to lift Ruyi Jang Bang (his staff) when it was supposed to be impossible (weighing in at 17,750 lbs) and besides being born of stone he stood in Lao Xi's 8 trigram furnace which made him indestructible on top of his other things (i.e. his armor and such). Though I suppose I could just say he has these abilities in his true form.
