Merge! Serpo Dover Demon Nessie! (合体!セルポドーバーデーモンネッシー! Gattai! Serupo Dōbā Dēmon Nesshī!?) is the twenty-fourth chapter of the Dandadan manga series.
Summary[]
Momo, Okarun, and Aira swim away from the Serpo Dover Demon Nessie as he starts firing off Nessie's water blasts from his mouth. After the water blasts cease, Momo, Okarun, and Aira notice the fused creature sucking in water from his gills, revealing to them that he needs to recharge to continue attacking. Using her Acrobatic Silky hair, Aira grabs onto the Serpo Dover Demon Nessie's neck to pull herself towards him and send out a flying kick. However, the Serpo Dover Demon Nessie intercepts her attack with a punch and sends out a volley of shockwave punches as he explains to them that he is a close combat fighter due to possessing the crab alien's arms. After catching Aira, the three become conflicted with trying to figure out a way to fight against the Serpo Dover Demon Nessie, however, after Okarun points out that the Serpo Dover Demon Nessie has the mantis shrimp arms from the crab alien, Momo develops an idea after Okarun points out the fused creature's mantis shrimp arms. The three then become separated after being hit by one of the Serpo Dover Demon Nessie's shockwave punches.
Viewing Momo as being the most dangerous, the Serpo Dover Demon Nessie prepares to beat her to death after having used up his water blasts. As he prepares to have his fist close in on her, Momo uses her powers to separate the water, resulting in the Serpo Dover Demon Nessie's mantis shrimp arms ripping apart due to them being unable to withstand the power when out of the water. The Serpo Dover Demon Nessie then resorts to trapping Momo by his teeth and dives down into the water to recharge another water blast that will split Momo in half. However, after being grabbed by the neck by Aira's Acrobatic Silky hair, the Serpo Dover Demon Nessie is defeated after Okarun uses her hair as a road to launch him and split the fused creature in half while also catching Momo in his arms
