I didn't find a thread on this so here it is. Rurouni Kenshin (or Samurai X as it's known by some) began as a manga by Nobuhiro Watsuki run in Weekly Shonen Jump before it became the classic anime. I was a fan when it's anime ran on Toonami but became a bigger fan when I read it's manga which is really cool.
Also given it's historical setting Kenshin surprisingly also has a lot of cool shonen/fantastic elements, many of which are inspired by comics like those of Spiderman, X-Men, Spawn, and even Blade to name a few. Is there anyone else that's a fan of this manga?
