what 4-0?
Please stop with that BS fanfic
OT:
sasuke is not a main character that's why he is far weaker than Main Character.
sasuke didn't work for his power-ups unlike naruto that's why he is too weak.
Sasuke's every power-up is due to itachi.
Sasuke beat Naruto in the academy,Valley of the end and at the begining of part 3 so thats 3 wins.Im missing the fourth,i don't know where they got that from.But did Itachi give Sasuke all Sharingan tomoes? Did Sasuke not activate each tomoe through battle?
-1 tomoe in each eye - Uchiha massacre,while chasing after Itachi.
-2nd tomoe in one eye - Against Haku
-2nd tomoe in 2nd eye - against Lee
-3rd tomoe in both eyes - Against Naruto.
He awakened his Sharingan tomoes through battle,and mastered it through battle experience and training.
The MS was awakened through finding out the truth about Itachi,and the murders of his family.Itachi let Sasuke win and planned out how Sasuke would become stronger so he could get revenge but deos that mean Sasuke was given everything? No.As i just explained he awakened the Sharingan through battle and learned how to use it from battle and training.
He fought Itachi til the piont where he passed out from exhaustion and awakened the MS from learning the truth.Did Itachi think Sasuke would ever find out the truth? No,he planned on Sasuke never learning the truth.
Sasuke learned how to use the MS through battle experience,hence amaterasu on Bee and Raikage and Susano'o throughout the Kage Summit.As for EMS,all he had to do was transplant Itachis eye in order to gain power,but he still needed to learn how to use it.
