Okay so this book at this point has just become head cannons I have for characters though mostly being sanders sides ones.

So anyway hear my head cannons for The subway masters

INGO-

Has claustrophobia
Is Demi-ace
Has adhd
Is basically a cat person (we treat the hisuian Sneazle line as cat's, so that is the biggest reason behind it)
(Based on a comic I have seen) has built up a tolerance for static electricity due to a joltik collecting phase Emmet had
If he is ever brought back to present time, he ends up in present day Shino while the protagonist of legends Arceus ends up in Unova.
Disappeared while the protagonist of black 2/white 2 was taking on the elite four

EMMET-
Has adhd just like Ingo
Has a fear of heights and being isolated (he's fine in small spaces, he just can't handle being alone)
Went through a phase where he just hoarded joltik
Would definitely end up befriending Volo without realizing he's the reason Ingo's gone (not immediate friendship + enough distrust for him to be suspicious)
Genuinely thought his first shiny joltik was sick.
Has gotten carried away with battling on the subway three times (One time he accidentally messed up the wheels, which is why his galvantula no longer has electro ball)
While being one of the people who is most on top of the search for Ingo, does not have that crazy conspiracy board most people depict him with.

For both-
Unintentionally adopted Rosa as their niece (she claimed them as her uncles and they just rolled with it)
Tears Will 100% be shedded if they were reunited
Befriended Elesa well trying to help her calm down one of her Pokémon ( twins were 15, Elesa was 16)
Both are very knowledgeable about hisui due to Ingo getting kidnapped by God & Rosa showing Emmet The lead she found while searching for Ingo

(Bonus headcanon for my interpretation of Rosa)
If Emmet is an angel of death, Rosa is a demon of mercy
Has a little Korean plastic baton (similar to what my family has) and uses it mainly to intimidate passengers that are not respecting the trains/harassing others
Had a dream of becoming champion and then gained a dream of becoming a Subway boss that rivaled the dream of championship
Upon Ingo's disappearance being announced, immediately forfeited the elite four challenge.
Has the following Pokémon: Serperior(ivy), Stoutland(Scout), Leavanny(cloak), Scolipede(stampede), Volcarona(radiance), Lilligant(petal), & Zoroark(Trix)
Runs a newer Subway system for the rotation battle system.
Is actually willing to fight God
Immediately saw the Subway Masters as uncle figures & Began to call them uncle Ingo and Uncle Emmet
Is a homoromantic asexual
Is the one with the conspiracy board on Ingo's disappearance

Take with these head cannons as you will
