I would like to give a mention to one of the most influential manga creators (on me) at least. The highly prolific Go Nagai!
This man created diverse comic series starting in the late 60's and they ran the genre gamut..raunchy comedies, apocalyptic gory horrors, countless heroic Giant Robots fighting to save the earth..juvenile delinquent gangs fighting tyrannical armed teachers, super heroic female heroes fighting evil cyborg lesbians..(hey wait a minute..).
.I think every comic he made was animated later by his own production series
and the guy is probably worth many millions of dollars. The guy is a living legend in Japan. His comics are way popular in Asia and Europe (especially France, Spain and Italy). In the US he is a cult figure and I was lucky to live near a large Japanese expatriate community and their book stores which had the mangas..I would buy what I could but alot of stuff I skimmed..
His art style is extremely cartoony but there is an intensity of violence and over the top rebelliousness that is amazing. This is the most un PC stuff you will ever see, although his giant robot stuff was more kid friendly (some of it anyway). Many of these were known as "Shogun Warriors" in the 70's and 80's the precursors to stuff like Transformers.
Of course there is subliminal influence and artistic influence on me..the dynamic action, the crazy spiky hair, the overturning of political correctness, the extreme and I mean extreme disdain for police and authority and also ultimately..the way he connects all his disparate series together (at the end).
Some Notable series
spoilers!) All from the 1970's and by no means exhaustive..this guy drew like ten series at a time (with assistants).
DevilMan- A series which starts out with a young good meaning punk possessed by a Demon who learns to control it to fight other demons.
What starts out as a villain of the week series takes an apocalyptic and extremely bleak turn where a human versus Demon war actually makes the humans seem more cruel..The children of Wrath indeed. And then the hero fights the main villain in the final battle..and loses. And the earth is destroyed.
Mazinger- The FIRST giant Robot series where the hero controls it as a pilot. Mazinger fights the countless enemy robots from an evil mastermind who wants to take over the world. EVERY Japanese giant robot show is descended from this series. Mazinger was best known for his famous Rocket Punch weapon..where his fists would detach and attack like missiles.
Getter Robo- The first giant Robot story where vehicles transform and combine to form the Robot. The misfit pilots of the three vehicles must fight an empire of intelligent Dinosaurs who emerge from underground and who want to take back their original home. More violent then Mazinger with nearly psychotic good guys!
Cutey Honey- A straight up super heroine story with a female student in a boarding school fighting an army of evil amazons (who are the teachers!) with her alter ego..Cutey Honey. Her male friends are next to useless and comedy relief. Crazy and fun and very non PC.
Guerilla High School- A dystopian tale where the violence in school gets so bad, the teachers arm up and become tyrants. The heroes are an odd duo..a bazooka packing rebel and his cross dressing androgynous (but two fisted) buddy. Crazy..
Violence Jack- A post apocalyptic tale from 1973, where a mysterious large knife wielding wild man avenges (but does not always protect) the weak and good hearted survivors who are at the mercy of biker gangs and other violent groups.
It is in this series where Nagai later links all his series together. Violence Jack gets expanded to basically be a sequel to DevilMan..it seems God(aka Go Nagai) did not like the ending of Devilman and then starts the world over..making nearly every Go Nagai character from all his series end up struggling in this post Downfall world. Jack himself turns out to be a part of Devilman and things go to their universe rending conclusion. This is Meta storytelling taken to an extreme. Seeing Cutey Honey, the guerilla high school duo and even some Robot characters going through hell and torture in this very grim series is cathartic. The heroic fun of before giving way to scarred survival.
You can see samples of what these character look like in my fave gallery.
To sum it up Nagai is a huge influence on both my art and crazy connecting of things (although I always like things taking place in the same universe form many creators).
