Quick breakdown for my best guess. Please post your disagreements or changes you want.
Alani: used to sing constantly. Then Pendles teased her constantly and she now sings alone only
Boldur: A series of ballads about bears
Kelvin: A nice bass, much more classic songs
Miko: Thousands of tiny voices coalescing into something absolutely terrifying. None can tolerate it but Kelvin.
Mellka: Not great, but appreciates punk rock
Thorn: too angry. Screaming if anything
El Dragõn: his own song from when entering the ring. Quite good now that he’s sung it so often
Kid Ultra: hums while playing the corresponding cartoon on his visor. Had all theme songs memorized
Kleese: no ability. He does not care in the least
ISIC: “Hahaha, not a chance”
Marquis: “the only music I make is the sound of hobos screaming”
Phoebe: sings along to classical music, absolutely terribly. Refuses to accept when other people inform her of such
Ambra: too high pitched. Burns ear drums
Attikus: tunes about killing his prior masters and.songs common among Thralls
Caldarius: physically can’t in his suit. He may pretend it doesn’t, but it bothers him very slightly
Deande: good voice. No interest. A waste of time and telegraphs your position to potential adversaries
Rath: loves opera. Strong baritone
Pendles: smooth jazz. To relax when slicing necks
Reyna: I honestly don’t know. Send help
Shayne and Aurox: “C’mon Aurox, sing!” " I’m going to rip out your intestines and whip you with them " “That’s not singing Aurox!” " I have been singing for thousands of years"
Toby: Blares metal music. When he dies repeatedly he takes out ear buds and plays some encouraging wiggles music
Whiskey Foxtrot: Classic Rock? Not sure
Benedict: only ever to Rick roll
Ernest: is yelling commands singing?
Galilea: soothing music. Loud music makes her… excited. She’ll lose control
Ghalt: baritone. Step into my offffffice
Montana: his own song
Oscar Mike: 3 songs
Seriously please help
