Serpo Dover Demon Nessie

Three creatures are stitched into one body here. Crowning it is the Serpo's square skull, which can part into four sections, while the bulk below belongs to Nessie, a long flippered shape carrying banded Serpo stripes that trail down the neck. The usual front flippers are absent, swapped out for the mantis-shrimp limbs of the Dover Demon.

Command rested mostly with the Serpo skull, yet it spoke of itself using the plural ware-ware, an acknowledgment that the Dover Demon and Nessie were folded into the same flesh. Savage and fixed entirely on its goal, the hybrid had been improvised as a hasty final move to close out the Serpo's losing battle against the three teenagers. Of the trio it picked out Momo as the deadliest, hungry to slay and dissect her above the rest.

As Nessie spun further out of control, the last living Serpo paddled over to the Dover Demon, bonded with both monsters, and locked onto the trio at once. Its opening assault came as pressurized jets of water spat out of the mouth, though the reservoir ran dry the moment its targets slipped clear of the beams. Drawing fresh water up through its neck to reload tipped the three off that the barrage could not be sustained and that the neck itself was the place to strike. Aira lashed her hair around it and drove a kick at the weak point, but the chimera blocked her, revealing that the mantis-shrimp arms it had taken from the Dover Demon made it a close-quarters brawler, then scattered the group with a flurry of compressed-air blows.

Fixing on Momo as the prime danger, it moved to club her dead and dissect the corpse afterward. Momo turned the situation around with her psychic grip on the water, splitting the surrounding flow so the mantis-shrimp arms lost the cushion they needed and tore themselves apart under the recoil of their own strike. The hybrid snatched Momo in its jaws, tried to drown her, and readied one more pressurized burst to finish the job, only for Aira's hair to seize the neck a second time. Okarun sprinted up the taut strand as if it were a runway, launched himself, and shattered the fused alien, pulling Momo free.
