|Shishio Makoto is the most powerful character and villain. all he had to do was punch kenshin in the middle of their battle and he goes down. and if he had kept attacking after kenshin was down he would have killed him. shishio rulez. |
I have only seen the anime, "Samurai X" and My favourite Kenshin opponent is Shogo Amacusa A.K.A. The Son of GOD. I dont know if he appears in the manga.
Shishio Makoto is not the most powerful character in the series/manga. The most powerful character is Hiko Sejiro XIII (Niitsu Kakunoshin), Kenshin's master. He is a true master of the Hiten Mitsurugi Ryu and also has the body stature to utilize it to its maximum potential. He is virtually unbeatable. Kenshin only defeated him because Hiko allowed him to (necessary to teach the Ama Kakeru Ryu no Hirameki). And you can technically say that he was an opponent of Kenshin when he taught the technique, so I will say Hiko Sejiro XIII is my favorite character.
