YMMV / Pluto

  • Iron Woobie: Gesicht
  • Nightmare Retardant: Behold Pluto's true form, gaze at that which has murdered and destroyed and- Hey, stop yawning!
  • Some Anvils Need to Be Dropped: 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, serving as a lackey to Dr. Roosevelt and not much else.
  • Viewer Gender Confusion: 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 "female".
  • The Woobie: Pretty much everyone qualifies for some variant of the trope. Heck, this manga might as well be titled "Robots and People Cry"
  • Woobie, Destroyer of Worlds: The eponymous Pluto, once you find out he's actually Sahad.
