First of all Thankyou for reading my fanfiction and sorry if i have harmed your sentiment in any way but my reasoning for Madara matching up to Garp is because of haki as well as chakra.Haki of Garp is obviously stronger than Madara.And 2.5 year is enough for Madara to condition his body physically because he also had Hashirama fast healing.From what I have seen Uchiha can copy handsign for jutsu as well as any taijutsu style if he has the physical capabilities just like sasuke has copied Lee lotus move and Madara not able to copy 8 gate because it doesn't need handsign and it's a internal technique where user opens the gate present inside their body while Rokushiki is all external move just like any taijutsu style.If we bring up a debate which character is strong and which character is weak from two entirely different anime then their will be no end to the argument because one piece fan will defend one piece character whereas naruto fan will defend naruto character.

I really hate this chapter.

This arc is getting on my nerve.
