As Shanks though, since Future vision, Mind reading, and Life Return (Seimei Kikan) merged into one, El is not afraid of anyone not only in terms of swordsmanship but as long as it is a one-on-one battle, even if the opponent is Whitebeard, the strongest man in the world and Kaido, renowned as the world's strongest creature, El is not afraid of them, not to mention Shanks who lost an arm and with his Haki greatly consumed.
