*the hand did not degrade and niether did the wall* "you cant hurt me" the figure says as it rips its hand out from tobi body "i can not be hurt......i can not be killed......i can not be touched" he says (the astrons wall didnt degrade since its been around for hundreds of thousands of years so i doubt it will begin to degrade if it is still pristine after all the battles and wars its been through lol)
