Now we know that four of madara's brothers were killed then it proves that he had 5 brothers in total.Then if all of his brothers awakened mangekyou and madara inserted all of their eyes in him then I think he may have awakened a new doujutsu which will be powerful than rinnegan or mangekyou sharingan to the power 5.What do you all people think about my theory.
