Who are the Serpo aliens in Dandadan? Explained

The Serpo aliens, or Seropians, are among the most chilling antagonists in Dandadan, Yukinobu Tatsu's bizarre blend of supernatural and sci-fi elements. Hailing from the planet Serpo, these humanoid aliens possess unsettling physical traits, including slug-like heads and black body patterns.

With no females in their population, the Serpos rely on cloning for reproduction, leading to a sinister agenda on Earth: abducting women to harvest their reproductive organs. Their dark intentions and eerie appearance make them a disturbing presence in Dandadan, adding a layer of horror to the series' already unpredictable and paranormal world.

The Serpo aliens, also referred to as Seropians in some translations, are an eerie humanoid species from the planet Serpo. Their physical features are simultaneously familiar and alien. With two eyes, two arms, and two legs, they bear a superficial resemblance to humans.

However, their slug-like heads, exaggerated lips, and bizarre body patterns set them apart. Their bodies are adorned with black line patterns that snake around their form, and they possess four fingers, toe-less feet, and a distinctive pale complexion.

Although their natural appearance is unsettling, the Serpos can disguise themselves, appearing as pale men dressed in simple, white button-down shirts and slacks. Despite this attempt at blending in, most characters in Dandadan can see through their charade relatively quickly. Still, their appearance, combined with their dark intentions, makes them a formidable presence.

The biology of reproduction and evolution in Serpo aliens

One of the most unusual aspects of the Serpo species is their biology. The Serpos do not have female members within their population, and as a result, they rely on cloning technology to reproduce. This method of procreation has stunted their natural evolutionary process, rendering them incapable of genetic diversity or adaptation.

The Serpos' reliance on artificial reproduction has made them desperate, as they cannot evolve or produce offspring through natural means. This desperation leads them to Earth with a horrifying purpose: to abduct and sexually assault women, aiming to harvest their reproductive organs in a bid to continue their species.

Role of the Serpo Aliens in Dandadan's plot

The Serpo aliens are introduced when Momo and Okarun make a paranormal bet to prove each other wrong. In their first major appearance, the Serpos abduct Momo, taking her to their UFO. What follows is a tense battle as Okarun, with the help of Turbo Granny, an eccentric and supernatural entity who possesses him, fights against the Serpo aliens to save Momo.

In the process, Momo, previously unaware of her latent psychic abilities, awakens her powers. She uses a devastating spin-kick to defeat the Serpos, a moment that cements her as a powerful force in the series. Though the Serpos retreat after their initial defeat, their role as antagonists is far from over. Trailers for the series suggest these aliens will continue to haunt Momo and Okarun, indicating their recurring role as intergalactic foes.

What makes Serpo aliens particularly disturbing is their motive for coming to Earth. Without the ability to reproduce naturally, they resort to kidnapping women and forcing themselves on them.

In their introductory scene, they attempt to s*xually assault Momo, stripping her down to her underwear in an effort to steal her reproductive organs. This moment, although short, is a stark reminder of the dark themes that Dandadan is willing to explore despite its comedic tone.

Although the Serpos are somewhat comical in appearance, their actions are anything but lighthearted. They are a violent and cruel species, both to their enemies and their subordinates. This mix of dark intentions and bizarre appearance creates a complex antagonist that fits well within Dandadan's strange and often unsettling universe.

Final thoughts

The Serpo aliens in Dandadan are more than just another group of antagonists. Their disturbing biology, cruel intentions, and ties to real-world Ufology make them a standout threat within the series.

Their presence adds a dark, unsettling layer to the world of Dandadan, where the line between the horrific and the comical is constantly blurred. As the series continues, viewers can expect the Serpo aliens to play a significant role in Momo and Okarun's ongoing battle with the paranormal.
