This is my first review, so please bear with me if it's kind of bad.

This Manga could go either way for the reader really, it had quite a bit of potential and could have went further if it had a little more support. It is a shame that it didn't, Zombie powder had an interesting story and plot line, the story of the Rings of the Dead and the Zombie Powder is rarely something seen in Manga making its story more original than most, along with good action scenes excellent fight sequences and some bizarre moves, and plot twists, it's more than enough to keep someone interested.

The artwork was good and clean with attention to detail, there was isn't a scene where to much there is to much happening in one image that could be eye distracting for the reader. Good character art, loved the main character Gamma's hair do. The only real downside is that it could be considered somewhat simple.

The characters of the story, are fairly well balanced and developed, each have their strengths and weaknesses, and can take care of themselves during a battle without relying on the main character to help them out all the time, compare it to the Bleach Soul Society arc, Ichigo being the strongest of the group, was depended on the most , this annoys me in Manga's when most of the main cast are dependent on the main character, it lowers the value of the characters till later on in the series (clearly evident in Bleach).

The main character Gamma along with his partner/friend CT Smith provide the major fighting power for the group and action scenes for the story, Gamma providing comical humour usually more present in his actions whereas CT Smith provides more sarcastic, subtle and somewhat mocking humour to balance it out. Gamma being the swordsman uses a wide variety of techniques and battle skill easily over powering the majority of enemies (with some techniques vaguely reminiscent of Ichigo's techniques), CT Smith provides marksmanship with incredible skill seen shooting out the pins of the wheels of a moving train without missing a shot. These two provide the main force and best battle scenes of the story.

The setting for the story is in a somewhat futuristic/sci-fi western universe, with guns, outlaws, bandits,etc, has a slightly more original setting and is similar to the Trigun series setting.

Overall, if your a fan of Bleach, then you should enjoy Zombie Powder (since it was done by the same Mangaka Tite Kubo), or at least give it a look. The story, characters and action scenes are great and it gave me a good laugh. My only problem is that it ended to abruptly and was left with that unfinished feeling, so for that i would give a 7 overall, i would like to have given it a 7.5 but that score isn't there, and if lasted longer and finished off without leaving such an open ending i would have probably given it an 8 or 9.

Still worth a read anyway.
