Because Kakashi > Itachi, that's why
Because Obito gave Kakashi his chakra and Sharingan. That's why he was able to use it so quickly without having to go through stages.
Obito never ever used da susano'o tho. So first time he get it he just shits on Madara and Sasuke Life and then most importantly tries to cheat the Solo God Itachi ??????
Just because we never saw it doesn't me Obito didn't have Susanoo. After all, every Uchiha who has been shown to have MS/EMS/Rinnegan has been shown to have a Susanoo. Madara, Itachi, Sasuke, even Shisui has been given Susanoo by Kishi. Why wouldn't Obito have it?
not valid sir, why would he hold out on one of the uchihas most powerful techniques if he had it?
sorry sir but you are being quite foolishObito was over confident. Not only did he have all of the former Jin (excluding Gaara), Kabuto's Edos, and Madara, but he had the Rinnegan and Kamui which made him intangible (until it was figured out anyway). Even when things started going badly for him, Madara was there to help control the Juubi. And THEN Obito became the Juubi Jin. In that span of time he had no reason to use the Susanoo.
LOL That Is Funnywhat if kakashi copy itachis aids?
sorry sir but you are being quite foolish
ayo how Solo God Itachi got no perfect Susano'o but Kakashi who got solo'd by the solo god got the perfect Susano'o?
