#fun fact: Emmet has a heart scale pattern! it's dead center on his face‚ which is why he tends to show up on more promotional advertising

Snakemas! Based on these guys, Iwakuni snakes (albino Japanese rat snakes):

This AU is (unfortunately) still in early development while I'm busy with school but there's some basic lore bits.

Half-monsters (hanmon) are a third group of organism between humans and pokemon. They are the result of ancient species from both groups combining and evolving over millenia to become specialized species of their own. They have monstrous appearances akin to pokemon, but wield only physical abilities like humans. Due to the nature of how they were formed and how they are viewed, most live in hiding, with only a few thousand individuals being observed and recorded

White Mountain Snakes are native to the Sin-Joh regions, showing up in traditional manuscripts as messengers of regional deities to guide and bring good luck to humans. Ingo and Emmet are children in a family that moved from Sinnoh to Unova. As such they consider themselves part of three cultures, and speak three languages

The twins are one of the only well known examples of hanmon in the present day. Most people are divided on their feelings about half-monsters, so they try very hard to skew the perception in a more positive direction. They act very proper with others and in public, only letting up and relaxing at home

Ingo does end up falling through the rift to Hisui. His main concern is that he fell right as the different clans were fighting over who was right, and having a "divine messenger" appear in Pearl Clan territory has caused a whole new mess for Ingo and the clanspeople

As for the serpents themselves:

The twins are constrictors, lacking fangs and instead having insanely muscular lower halves for wrapping and crushing prey in their grip. Depending on the size of the food they're eating, they might also just crush it with their bare hands to make it more manageable to swallow quickly

They are looooong, something like 10m in length from head to tail. The subway has multiple posters up warning patrons to watch their step in case they trip over them in traffic

They are awfully sensitive to temperature change. They sleep under a giant electric blanket, wear thick uniforms, and set the driving car temperature to be warm. Summer is their best working season, however they tend to stop working in winter to hibernate for about 4 months, much to the dismay of Battle Subway fans, staff, and local grocers

They'll shed about thrice a year and assist each other with peeling it when possible. This is mostly since they aren't dexterous enough to reach parts of their back. Shedding time means it's time for this little competition of theirs where they attempt to pull the longest pieces of shed possible off the other. Ingo is not very good at dealing with Emmet's dry ass and ends up accidentally cracking it most of the time. They sometimes give the scrap shed to Elesa for use in fashion outfits

Ingo's mouth is much narrower than Emmet's, he often has to stretch his jaws to accommodate something Emmet can eat easily. As a result the tissue connecting his jaws in the front is more stretchy

The twins have different organ locations due to their long structure. This usually doesn't affect their job but if you give them a hug you will feel the heart pumping in their abdomen

Thanks to all for reading this far. As a treat have Ingo and Emmet in their separation outfits, Emmet in his uniform and Ingo in the garb gifted by the Pearl Clan.
