The Human/Hero/Cage
Smeargle = lots of "Kris is an artist" implications lately...also is a dog technically
Bisharp = imagery relating to both knights (Kris' dark world outfit) and knives
Luvdisc = ...it's a heart lol...
Lycanroc = obligatory "changing in the dark" reference... could go to any lightner realistically- I see it more as a group Pokemon between the Fun Gang than anything tbh
The Monster
Tyranitar = basically the Godzilla Pokemon...
Deino = reminds her of Kris... plus evolves into a cool dragon
"Angel"
Sawsbuck/Delibird = Christmas/winter themes
Dedenne = caught after she gets over her fear of mice
Cramorant = it reminds her of Berdly lol
"Number 1 Student"
Unown = being the smartest guy in class, he took it upon himself to seek out every Unown and study the language associated- hoping desperately to find something everybody else has missed
Inteleon = looks very smart in his opinion- Intel (ligent) (Chamel) eon
They could very well keep parts of their Light World teams, for what it's worth.
The Human/Hero/Cage
Gengar = scary face/trickster type... would help with pranks
Corviknight = bird/cage+knight references... not very stuck on this one
Lycanroc = "changing in the dark" to fruition !
The Monster
Tyranitar = basically the Godzilla Pokemon...
Deino = reminds her of Kris... plus evolves into a cool dragon
"Angel"
Cryogonal = snowflake... ice thing... ice powers....
Froslass = also snow/ice powers- has a white cloak thing- and also Froslass lore is kind of thematic for snowgrave
Eiscue = I mean... bird in ice... would only have on snowgrave

Inteleon = looks very smart in his opinion
