Manga. Japanese comics that are in black and white and usually follow the stories of teenage protagonists. The plots are usually heavily cliche' but you know what? I still love the stuff.
In case you can't tell by looking at the visuals in this entry, some of my favorite manga is of the Shonen variety. In fact, Shonen manga was the first manga I ever picked up. I bought four graphic novels on a Thursday before work five years ago. What were they? Dragon Ball vols. 1-2 and Dragon Ball Z vols. 1-2. I would have bought InuYasha manga that day, but the asking price for the slightly bigger sized editions of those books was $15.99 so I passed I brought Goku and the gang instead. I've been hooked on manga ever since.
Some of the most popular manga artists have admitted to being huge fans of Akira Toriyama's Dragon Ball (in Japan, the manga for second part of the DB series, DBZ is also called Dragon Ball) and you can see the influences in their works. As repetitive as it can get, I love all these colossal fights that wipe out buildings and tear up the landscape. There have been a number of fights like these in other manga like Bleach, and Naruto. Some of my favorite fights in these series? Gohan vs. Cell. Gohan going Super Saiyan 2 and beating the crap out of Cell and then defeating him with only one hand is still one of the greatest moments in that manga. For Naruto, well Naruto vs. Gaara is still at the top of my list. Yeah, I realize the constant power-ups Naruto and Sasuke had during their fight made for an epic battle and Naruto used even more power from the demon fox within, but I'll still take Naruto vs. Gaara over Naruto vs. Sasuke any day. I think protecting one's friends made for a better battle as opposed to trying to save a friend from leaving who was clearly being more of a jerk than usual. Naruto's 2000 hit combo, summing Gama-Bunta, transforming into the demon fox, man, that fight was awesome!! For sweet Bleach fights, well I've always been a fan of Ichigo vs. Kenpachi for a number of reason. Ichigo literally came back from the dead, much to Kenpachi's surprised and really pushed him to his limits. Kenpachi is one of the few truly bloodthirsty, combat junkies in the Bleach world. This guy loves to fight and I thought that brought even more to the table in that battle.
Rurouni Kenshin has what I'd consider probably one of the best stories in all of manga, surpassing everything else I've mentioned. On top of that, I feel that Nobuhiro Watsuki draws some of the best action sequences, and I'm not just talking about manga, I'm talking about in general. Watsuki is also a huge fan of American comics and some characters models from Marvel comics have crept their way into a few of his designs. As for my favorite fights in RK, well there are far too many to list. So I'll just say that I don't think there's been a fight in this series that I didn't like. No joke.
I was originally gonna mention a few other mangas but this entry is already turning out to be a bit longer than I planned, so I cut it off right here and discuss more manga in another entry.
