Pluto (プルートウ, Purūtō?) is an on-going manga serial by Naoki Urasawa published in Big Comic Original starting in 2003. It is based upon events from the classic series by Osamu Tezuka, Tetsuwan Atom (a.k.a Astro Boy, literally Iron-Arm Atom). Specifically, the series uses the characters and original story from the popular "Chijou saidai no ROBOTTO" ("The World's Strongest Robot", Dark Horse's version: "The Greatest Robot on Earth") storyline from the 3rd volume of the manga (as well as a few elements from the 2003 anime series version of the storyline with bits and pieces added from other stories by Tezuka) and reinterprets the plot as a murder mystery and noirish suspense thriller. In terms of both tone and visual style, the series is a complete and modern re-envisioning of the Astro Boy universe dissimilar to the original manga.
But isn't Abra human? He was human during that war (what's that place called again?), then after the war he became half robotic, but Bora existed during the war, that's why I don't think Abra is Bora, unless he was a robot to begin with. Also, the Bora from Wassilly's mind was completely different than Abra, the sound it makes, the shape, etc/ Wassily isn't a robot to be able to tell when a robot switches bodies, that also lead to my understanding that Abra isn't Bora. Of course I could be wrong, so we all have to wait and see
