Twisted Wonderland: Disney Character Theme Songs [Contains Spoilers] 

As promised, the reasons:
Riddle - Emotionally manipulative mother anthem
Ace - I couldn’t find any that suited him perfectly but this song kind of matches his energy??? It sounds like how he describes himself at least.
Deuce - He’s going the distance, he’s finding his own way
Cater - I personally believe that Cater is based on Cinderella, and even disregarding that, in this song the stepsisters are causing mayhem and Cindy is trying to stay zen but failing (like Cater)
Trey - Chapter 1
Leona - Because in chapter 2 he decides to try one last thing and then fails. Also he’s lazy like in the song, and he trains people for spelldrive.
Jack - He came to the school to learn from Leona and that’s very cute so
Ruggie - Sneaky Broke/Sneaky Broke solidarity
Jade - Because mushrooms = high
Floyd - because he doesn’t worry and I couldn’t think of anything better
Azul - Because he traps people into contracts and makes them his badaboom ‘I put a spell on you and now you’re mine’
Azul 2 - Because he put so much work into becoming a not a loser (he’s still a loser but we love him for it)
Kalim - His friendship with Jamil (however one-sided) reminds me of this song
Jamil - BECAUSE HE WANTS TO BE OUT THERE. HE WANTS TO BE FREE
Vil - He believes in putting in the work towards his goal and does it every day, plus he was raised by his father so even better
Vil 2 - This one is self-explanatory
Rook - He’s very welcoming and enjoys the finer things (also French)
Epel - THEY WANT A DOCILLLLLLE LAMB NO ONE KNOWS WHO I AMMMM
Ortho - :(
Ortho 2 - Because he wants to get out there and experience life
Idia - There were no songs about being a shut-in otaku so I went with the keeper of the dead/dead brother angle
Sebek - This whole song is just a simp’s ballad and if that doesn’t describe Sebby idk what does
Lilia - Because…he has children? He lives in the woods? I swear I had a reason but I can’t remember it
General Vanrouge - Just suits his story super well I think
Silver - Because he’s often called different than everyone around him, + he’s beautiful, + I like the song
Silver 2 - Chapter 7 :(
Malleus - He’s desperately trying to convince himself he isn’t lonely but we see past it (+ parallels to Silver)
Malleus 2 - HIS RELATIONSHIP WITH YUU (platonic or romantic, whatever floats your boat), + he’s resigned himself to being alone forever and knows he’ll probably never be loved :(
[Very poorly worded but here you are. Thank you for watching :D]
