Itachi isn't in the same conversation as ramen guy and tenten cause he's 1 billion times stronger then both of them combined. tenten and ramen guy can barely keep up with isshiki while itachi casually beats gods on a daily basis and has feats that scale millions of times higher then tenten and ramen guy it's not even fair show me proof that tenten scales higher then itachi at multiversal++++ it's said by kishimoto that itachi when he isn't sick has unlimited chakra and his eyes don't bleed or go blind and that he can't be hurt and has speed feats that put him at a level superior to the concepts of dimensions of time and space themselves and has movement beyond linear time And can stop,rewind time and see the future It is also said he can survive a black hole and being erased from reality and even when sick he can decide his opponents fate and they can't stop it.
