What a nice phrase there, the world's tiniest hero. Japanese hero media seems to be rather popular; my favorite is Ratman~ Seems the English official releases got cancelled(as they usually do sheesh), but the original JPN volumes are still out there to read~

I like the summary they gave for this series. Suits it perfectly. I'm only on chapter 21, but so far I'm sold. A large portion of parody and humor, some good amount of action and intrigue, some nice warm fuzzies, and who cares if it's got a few cliches here and there. It's self aware enough that doesn't bother me.

The setting is a lot like Tiger and Bunny, where you have commercial "heroes" who are pretty much a mixed bag of those who work for the fame and glory and those who do for justice. And those who are just there to sell stuff. The "villains" are not so villainous as they appear... OR ARE THEY? The "evil" minion Jackies... are hilarious. The protagonist Shooto is just a kid who reeeaaally wants to be a hero and somehow or other gets contracted to be the opposite. He's cute, stubborn, determined to carry out justice at any cost, powerful (and kind of scary) when it counts, pretty much your typical shounen protagonist.

The story is funny, it's got good art, there's some mystery to it all and a tiiiiny bit of romance so far. Nothing too deep but enough to entertain and interest.

Falls Off

This manga started out really good. It had an interesting world and fun characters. My only gripe is minor enough that it does not bear mentioning.

However, after the existence of Ratman becomes public knowledge, the series starts to fall off. I thought that would be the time when things got serious, where the themes that had been alluded to in the beginning of the series would be explored more thoroughly, and possibly when we explored the political and social repercussions of the existence of heroes.

However, that doesn't happen. Volume 11 brings almost every important plot points to an abrupt and unsatisfying close, in a way that doesn't really make sense.

My best guess is that Ratman wasn't as popular as the publisher thought it would be and they told the mangaka to finish it in less than ten chapters. The same thing happened to Battle Angel Alita, which was then continued by a different publisher under the name Last Order.

Hopefully the same thing happens to Ratman. Until then, the 8/10 only applies up until Volume 10.

Its all come down to what do u want in a manga. This manga is typically a happy manga with light drama that really wont bring u to tear. However, it have some decent comedies with the jackies in the early chapters. Not only that, decent art too. If u want a fun and relaxing thing to read, this is for you. If you r looking for some grand advanture, this isnt the right one.

Ratman was a good series until about 30 or so chapters in which the author writing skill deteriorate to a point of him writing a random plot out of no where and can easily be pick apart for all of its plot hole that all end with Ratman being consider more and more like a hero which is good in some way but it get old after 30 or so chapters, to a point where there aren't really much plot creativity left for the author.

ok give a good guy a super suit..... then tell him he (by contract) is a villian.... i just got to laugh at the sad turnout for our little illfated "hero"... then you throw in the escapades of the mime-like jackies and its perfect.... i mean those dudes just know how to be in the worst place at the worst time.... then when you think they are completely useless they do something right, and to be honest in my opinion i mostly kept reading to see what the heck they will pull off next.... the jackies are just awesome smile

The "antihero" category is misleading

It is hard to have an antihero main character in a shounen manga. Sometimes it works /Majin Tantei Nougami Neuro/ but without making it borderline seinen it feels half-assed.
Spoiler (mouse over to view)
The main character is typical shounen male lead, in other word a hero with strong moral compass, witch is a polar opposite of the egoist, manipulative antihero. The method of accomplishing their goal is just too different
. The other characters are great,
Spoiler (mouse over to view)
except the sempai who is just a female clone of the main char
. The comedy is generally good but nothing groundbreaking. If you like shounen manga check it out.

The usual crap

Kid gets superpowers. Kid has ideals questioned. Kid's power of friendship and kindness triumphs over child soldiers, human experimentation and black box organizations. Everyone goes home happy.

(6 volumes translated) This is shallower than a Saturday morning cartoon plot. The story keeps hinting at the darker aspects of human biological weapons development but never goes anywhere with it. Instead, the story plays it safe with the usual "beat up enemy = become their friend" pattern. The whole synopsis about becoming a villain? Never explored. The heroes? Never explored.

I know most people hate the cliche hero story but Shooto is a genuinely nice guy with his own faults so he's both likable and the reader can relate to him. The art isn't the greatest in the world but it's decent in its own sort of charm. The characters are all pretty cool and Ratman is such a badass looking kamen rider inspired anti hero that you just can't hate him, kinda reminds me of a cross between Venom, Batman, and Kamen Rider.
