Slugterra (mostly Saturday) headcanon dump since I haven't done one in a while :D
Mr. Saturday suffers from myopia (short sightedness) but refuses to get glasses because he doesn't think they would look good on him. Main reason behind this one is that scene in Dawn of the Slug where he doesn't realize there's suddenly a fucking CAVE TROLL in the crowd and in Mission: Improbable where he somehow doesn't see Pronto when he's calling the kitchen
On the topic of Saturday's poor eyesight, he's also easily irritated by bright lights because black is the color that absorbs the most light and is also the color that makes up 95% of his eyes. This one came to me after randomly remembering a part in the Wild Kratts episode about cheetahs where they explain how that black sports paint keeps the sun out of people's eyes so Saturday has that but like it just goes straight in his eyeballs.
Darkbane do not know the difference between a name you give an inanimate object, and a name you give a living being (like a pet or a person) but they think the names for inanimate objects sound more intimidating so they prefer to name themselves (or in rare cases, their children) after those.
C.C has a tendency to act like any minor inconvenience is the worst thing that's ever happened to him in his entire life, this habit stopped after the Shadow Clan got him in Lightwell.
Saturday has an anonymous slugnet account where he talks shit about the other people in the citadel.
And last but not least, Blakk at one point had a phase where he almost exclusively listened to the closest thing Slugterra has to fallout boy, this phase was more recent than you probably think it is.
It's been a bit since I made a post like this, I forgot how fun it is to write these!
