- Alternate Character Interpretation:
- Some of the Western fanbase theorizes that Dororo is transgender (specifically a transgender boy); the child identifies and refers to herself as a boy after being Raised as the Opposite Gender, so they see it as fitting the definition of "identifying as a gender different than the one assigned at birth." Other theories have it as Dororo subconsciously realizing what dangers await her if she lives as a girl in their Crapsack World of an era, so she just lets people presume she's male.
- Dororo and Hyakkimaru's relationship in the live action film. Dororo doesn't seem to hold any romantic feelings for him and only sees him as a friend... or is she simply waiting for him to regain the other half of his body back and become a real man before dropping her masquerade?
- Catharsis Factor: After seeing Daigo's men murder Mio and the kids she's taking care of, watching Hyakkimaru slaughter them all definitely counts as this.
- Ear Worm: GET IT OUT OF MY HEAAAAAD!!
- Ensemble Dark Horse: Hyakkimaru's adopted father Jukai is loved just as much by fans as by Hyakkimaru. His 2019 incarnation especially is the source of fan affection, for havingmore development as a character and as Hyakkimaru's Parental Substitute.
- Fan-Preferred Couple: Hyakkimaru/Dororo has had supporters for decades, and most have them be a couple after the latter comes of age or is an adult in some continuities.
- I Am Not Shazam: No, the Dororo of the title isn't the tall one with prosthetics, that's Hyakkimaru. Dororo is the younger one that travels with him.
- It Was His Sled: Dororo being female is a twist people have known for ages, and people usually either exaggerate it or openly show it in later adaptations.
- Nightmare Fuel:
- Picture a little baby, with its big head, no hair, and large eyes. Now, take away those eyes and leave holes behind. Now take away the ears and the nose. Take away the limbs, leaving only a torso. Now, to top it all off, take away the skin of that baby, leaving behind what looks like a tiny skull covered in blood. And that baby? It's alive. And breathing. That's what happened to Hyakkimaru. The demons left him with the barest minimum of humanity. Most people who find the baby are astonished by not only the fact that he's alive and breathing but that he is apparently running on sheer determination to live so much so that everyone can pick up on it from the midwife to the doctor who finds him.
- Nightmare Retardant: The demonically possessed katana Nihil corrupts its user. When Dororo picks it up, his Bratty Half-Pint dialogue doesn't change at all, so the audience is briefly entertained with the thought that the only difference between that trope and a mass-murderer is will and means.
- Torn down quite a bit in the 2019 anime, in which during the first time the soldier held Nihil, he was fine too. He only changed after forced by his daimyo to kill numerous people as a sick experiment. Dororo is never seen to kill with the sword - even tugging at it and holding it back.
- Thoroughly averted in Blood Will Tell. The instant Dororo picks up Nihil, his skin turns ashen, his eyes blood red, and his mannerisms and movement in the subsequent boss fight are jerky, stilted and bestial, all while he growls, roars and screams like a deranged, wild animal.
- They Wasted a Perfectly Good Plot: Later fans of the series would usually say this in regards to the treatment of Hyakkimaru's missing parts in the original manga. While the adaptations tried to play with how messed up his body really is, they argued that the original didn't go far enough to show us his condition, and he was otherwise a normal person if you ignored the telepathy explanations.
YMMV / Dororo
