Ok list of all the hermits and what they will be for Halloween. I'm going in the order I decided it in.

Zedaph: Unicorn(because I can)

Mumbo: Charrot

Grian: Cat

Scar: Stitch (I want to draw this so bad)

Stress: Fairy

Iskall: Pirate (because I can't think of anything better)

Cleo: Spider

Joe: A Librarian (Seemed fitting)

Etho: Elf

XB: Sheet Ghost (I know nothing about him)

Ren: Obi-wan Kenobi (Seemed right with his base and all)

Impulse: Ghast

Xisuma: He's always in a costume so who cares 

Cub: Vampire

Vintage Beef: Llama (Self explanatory)

Keralis: He just reuses his bee outfit

Tango: Werewolf (I thought it was interesting)

BDubs: Phantom (This one is for pure irony)

Doc: G O A T

False: Someone who looks like they just came out of a zombie apocalypse 

Hypno: A Magician

Xander: Panda (You can't tell me that it wouldn't be adorable)

Chocolate Unicorn: Dragon (Note: I am not going to be a dragon myself)

Wels: Thunderbird

Hels: He won't even celebrate

TFC: Captain Nemo (I had to have TFC be some really old character) 

Jevin: Doesn't really like costumes (mostly because being part slime makes it a hassle to change clothes)

If I missed anyone please tell me.
