Naruto & Kyuubi 4 form will he be able to contol it
Do you think in the future as Naurto ages and because more in control of his power do you think that he will be able to control KN4 form and even add more tails to the form? Personally I think Naruto is still young and out of control but as time progress I think he will be able to control the KN4 state but no for long period and he can regain control and go back to regular naruto form or a safer Kyuubi form. Sorta like if you read Bleach ichigo and his hollow form.
