Of course, I can't talk about robot manga without talking about this one. While it's only tangentially connected to one of mecha's founding works, it's one of the most critically acclaimed manga in the US and it's time for me to add my own praise to that pile.
PLUTO, by Naoki Urasawa. First published in 2003 and first published in North America in 2009.
PLOT:
Mont Blanc was considered one of the world's greatest robots, a beloved mountain guide and forester in his home land of Switzerland. Then he was found smashed to smithereens in the remains of a forest fire. That same day, a notable robot politician in Germany was also killed. It's up to the android detective Gesicht to investigate these cases. As his investigation grows, he believes that these deaths are connected to a terrible conspiracy to destroy both the world's greatest robots and the humans who want to protect them, and that whomever is behind it may not be human themselves.
