Let's say Itachi never transferred Amaterasu to Sasuke. Using your imagination, what do you think would be Sasuke's Mangekyou Sharingan power? I can't think of anything right now, but I want to hear everybody else.
good onei think sasuke would have had ameterasu even if itachi didnt give it to him now in addition to his black flames he can control him (i think thats his second power to be able to control the amerutrasu)
