Serpo

* Disguise
* True Form

The **Alien Serpo** (セルポ星人, *Serupo Hoshibito*?, *Viz*: Serpoian) are an entirely male alien race who come from Planet Serpo.

In *Dandadan*, they serve as minor antagonists during the Turbo-Granny Arc and primary antagonists during the Serpo Arc.

## Overview

Due to their race being exclusively all male, the Serpo have no way of reproducing naturally and resort to using cloning technology. However, since biological evolution cannot occur within identical beings, the Serpo found this solution to be ineffective and seek to gain reproductive organs by abducting humans from Earth and stealing their sex organs (or "bananas").

## Physical Characteristics

The Serpo wear oddly male humanoid disguises, along with human clothes, which is a collared, button up shirt with a left breast pocket that is tucked into their pants, a belt, and shoes.

The true bodies of the Serpo are slug-like head aliens with large, prominent lips and a line pattern body with a fat stomach. They have two fingers and two thumbs in each hand, while their feet possess no toes but are split to resemble as such.

## Psychological Characteristics

The Serpo behave forceful and violent towards the human species when choosing to abduct them but are oblivious to this, believing that their actions are peaceful. They also prefer to abduct female humans rather than male humans and have stated that they despise encountering ones that act barbaric. Another interest they have are the supernatural powers of humans who have gained powers from spirits that surpass their own knowledge of science and technology.

Other than being obliviously hostile towards humans, the Serpo also behave cruelly towards their subordinates, having no concern for the hired help's well-being and viewing them as nothing but cheap and easily replaceable. While the Dover Demon took on the task of fighting Momo, Okarun and Aira, the Serpo induced force labor whenever it performed poorly by deducting its salary and forcing an upgrade in power in spite of its objection.

The Serpo have tools stored between their legs for various purposes:

* **Reproductive Tool**: A cable used for sexual intercourse with a human female to extract their reproductive organs. The cable can also be used to increase the power of an alien.

* **Scissor Tool**: A single large scissor that can be used to extract reproductive organs other than using the sex organ tool.

* **Amalgamation Cables**: Two cables used to fuse a Serpo's body with one or more lifeforms.

## Abilities and Powers

**Super-Intelligence**: The Serpo are incredibly intelligent, possessing advanced skills in science and technology. With their advanced technology, they are able to create clones of themselves, construct tools within their bodies, a UFO, and a device that can cast the Empty Space.

## Synopsis

### Turbo-Granny Arc

At the Nagi Hospital, the Serpo encounters Momo Ayase and forcibly abduct her to extract her reproductive organs. Before they could begin their procedure, a possessed Okarun unexpectedly appears out of Momo's phone and attacks the aliens. After managing to subdue him with their psychic powers, the Serpo proceed with the procedure on Momo, however, after overstimulating her brainwaves, the Serpo accidently unlock Momo's psychic powers and are defeated after the girl destroys their ship.

### Serpo Arc

After becoming intrigued by what they saw from Okarun after being possessed by the Turbo-Granny, the Serpo, along with the Dover Demon and Nessie as subordinates, locate and confront him at school with the intention of taking his supernatural abilities for themselves. However, they are met with an unexpected interference from Aira Shiratori, a spiritual aware human girl who awakens the power to use Acrobatic Silky's abilities. The Serpo have the Dover Demon fight back against her and use their combined psychokinesis to subdue both Okarun and Aira. However, the Serpo become shock to see Momo's arrival and her using her psychokinesis to repel theirs to allow Okarun and Aira to move about. To gain the upper hand, the Serpo forces an alteration on the Dover Demon but are disappointed to see that it is fighting poorly against Okarun and Aira's coordinated attacks. The Serpo then find themselves attacked by Nessie, despite bringing along the undersea monster for their mission.

With only one member left alive, the Serpo uses his Amalgamation Cables to merge himself with Nessie and the Dover Demon to eliminate Okarun, Momo, and Aira. The Serpod Dover Demon Nessie then starts to attack them with high-compression water blasts from its mouth but soon runs out of water after the three managed to evade his beams. After absorbing the water from his neck to reload, Okarun, Momo, and Aira realized that the Serpod Dover Demon Nessie can't fire the blasts continuously and believes that attacking his neck will cease his assaults. The Serpod Dover Demon Nessie then finds its neck grabbed by Aira's hair and sees the girl coming towards him with a kick aimed towards his vital spot. However, the fused alien intercepts her attempt with a punch, stating that, despite his appearance, he is a close-combat fighter due to having the Dover Demon's mantis shrimp arms and hits them with a barrage of air compressed punches that separates them.

Viewing Momo as being dangerous, the Serpod Dover Demon Nessie confronts her with the intent to beat her to death and dissect her body later. However, before he could land his attacks, Momo turns the tables by using her psychic powers to divide water, knowing that the Serpod Dover Demon Nessie's mantis shrimp arms would be ripped apart due to it not being able withstand the shock from its own punch when out of the water. The fused alien then catches Momo by his teeth, attempts to drown her in the water, and prepares to fire another high-compression water blast to see to it that she is eliminated. However, the Serpod Dover Demon Nessie finds his neck caught by Aira's hair once again and panics as Okarun uses it as a runway to launch himself and destroy the Serpod Dover Demon Nessie.
