* CompleteMonster: [[MasterComputer Dr. Roosevelt]] is the [[NonActionBigBad immobile]] supercomputer who serves as the President of Thracia's personal advisor, and is [[GambitRoulette ultimately the root of all the trouble]] in this reimagining of the ''Manga/AstroBoy'' story arc "The Greatest Robot on Earth". Seeking total subjugation of all humans and robots alike, Roosevelt [[ManipulativeBastard manipulated Thracia]] into going to war with the seemingly-peaceful country of Persia, resulting in the deaths of millions of robots and hundreds of humans. Afterwards, with Persia now a desolate land of poverty, Roosevelt manipulates events to allow [[TheHeavy Dr. Abullah]] to create Pluto, a powerful robot that murders numerous good-natured robots as "revenge" for Persia's decimation, all according to Roosevelt's plan. In the end, Roosevelt is revealed to have assisted Abullah in planting an Anti-Proton bomb that will first lead to the obliteration of Thracia, then the deaths of [[KillAllHumans 90% of the human race]], at which point Roosevelt plans to rule supreme over whatever is left of human and robotkind. Leaving death and destruction galore across the world with his machinations, Roosevelt stands as a testament showing that, just as a machine can develop a soul for good, nothing is to stand in the way from one becoming selfish and sociopathic.
* IronWoobie: Gesicht
* NightmareRetardant: Behold Pluto's true form, gaze at that which has murdered and destroyed and- Hey, stop yawning!
* SomeAnvilsNeedToBeDropped: Pluto has a few messages that it presents in a pretty upfront fashion, but they're things that were of supreme importance in its day and are still important now.
** Hatred is one of the defining traits of humanity, but is also completely poisonous, consuming people's lives and nothing good ever comes of it outside of generating more and more hatred and suffering.
** The 39th Central Asian War, in which Persia was invaded by The United States of Thracia under the pretense of them having "robots of mass destruction", is very transparently an analogue of the Iraq War (which was happening around the same time), and functions as a heavy critique of that conflict, lambasting the ideas of imperialism and american exceptionalism that surrounded the conflict. The President of Thracia is even portrayed as functionally inept, [[spoiler: serving as a lackey to Dr. Roosevelt and not much else.]]
* ViewerGenderConfusion: Epsilon. What makes it even more difficult is that ''Pluto''[='=]s Epsilon is a composite character of the original & 2003 series Epsilon, the latter of which was "[[RobotGirl female]]".
* TheWoobie: Pretty much everyone qualifies for some variant of the trope. Heck, this manga might as well be titled "Robots and People Cry"
* WoobieDestroyerOfWorlds: The eponymous Pluto, [[spoiler: once you find out he's actually Sahad.]]
