What are the general characteristics of the serpentine in OBNL? Do they have eyelids? Are they exclusively carnivorous? Do they have a plantigrade or digitigrade leg structure? Do they have sensory pits near their eyes? Can they hibernate? Do they experience indeterminate growth? Etc.
Hey! Thanks for the ask! Worldbuilding and weird biology questions are always welcome!
A large part of my Serpentine biology hcs comes from 2 underlying principles in my AU: 1) Humans bit by Fangpyre become fully Serpentine themselves, not just green snake creatures like the Fangpyre-bit vehicles and 2) Humans becoming Serpentine is a common enough phenomenon that all living Serpentine by the start of S1 canon have some degree of Turned (former human) blood in their ancestry.
The original Serpentine who came to Ninjago (hoo boy, not going to get into that one right now, thatâs a whole other lore deep dive), may have had more exclusively reptilian features, but when they started Turning humans, more human-like features started to creep into the gene pool.
For instance, I hc OG Serpentine as having the lower half of their torsos being pure snake. Two-legged Serpentine didnât start happening until human Turnings.
(This is how I justify Aspheera and Char having tails despite not being generals- they lived in a time where Turned traits havenât yet become widespread enough to affect the overall phenotype of the general population.
Conversely, the modern Anacondrai have retained their tails because their blood has remained the most ancestrally pure. Turnings rarely, if ever, result in new Anacondrai.)
Although not true mammals, some of the human traits I assign to Serpentine are
Warm-blooded. While their metabolism runs slower the average human, they are not impacted by cold the way reptiles are. Serpentine are capable of hibernating, but itâs not a deep sleep. Itâs more similar to torpor experienced by bears, where body temperature remains relatively high and can wake up and move around when necessary (Hence the Hypnobrai rousing fairly quickly when Lloyd stumbles into their tomb)
Yes they can eat other foods besides meat. While Serpentine are primarily carnivorous, their bodies can digest plant matter when needed. They can also taste/crave sweet, a holdover speculated to arise from their post-human biology.
No indeterminate growth. Serpentine undergo a rapid maturity process, hitting puberty at around 12, adulthood at 30, and living until theyâre 250-300 years old.
As for sensory organs, I do see the tribes as having different abilities when it comes to that. For instance, Constrictai have an electromagnetic sense that enables them to find their way around underground while Fangpyre can sense heat and are especially sensitive to the rush of blood in a potential targetâs arteries and veins.
