And how is Sasuke rivaling the protagonist now? thought so,It seem your brain can't comprehend the manga if you think a Madara is just a powerful shinobi i can't believe you even bothered to post that crap, if he wasn't a genius how is it his the one that unlocked the Rinnegan and found out the secrets about the sage and the Juubi all Sasuke has is part 1 hype which lee and neji was also said to be genius.
Actions speak louder that word of mouth.
Lol as expected, you don't understand storytelling,
it's not my brain who can't understand, it's YOURS
Madara does not fit the role of rival to the protagonist because he doesn't have the rival bond with the main hero as does sasuke and naruto
Genius doesn't mean abilities, it means the relationship between characters
let's look at it
Madara: Never Developed a bond of naruto
never grew up with naruto
never was friends with naruto
Never teamed up with naruto
Madara Has NO CONNECTION with naruto, as a rival does to a MAIN HERO
let's look at sasuke
Sasuke: Developed a bond with the main hero
grew up with the main hero
Had the rivalry theme with Main hero,
Has teamed up with the main hero.
Madara is not the Yin to naruto, SASUKE IS
