the performers are:

Geega doing the initial narration as Cruella De Ville

Apricot (Froot) as Scar

Hime Hajime as Oogie Boogie

Matara Kan as King Louie

Zentreya as Gaston

Haruka Karibu as Ernesto de la Cruz

Projekt Melody as Rasputin, performing "In The Dark of the Night" from "Anastasia". With Disney buying Fox, it falls under the umbrella now, I guess...

Kson Onair as Jafar

Michi Mochevee as Bruno Madrigal

Kuro Kurenai as Mother Gothel (having the one guy in VShojo doing a woman's villain song, of which Disney really has few, is kind of hilarious)

IronMouse as Dr. Facilier

Not appearing: Henya the Genius, who was recovering from COVID-19 induced pneumonia at the time, but if you look at the end, you can see we missed out on Agent Teakettle singing "Poor Unfortunate Souls"...

And yes, for those that don't know them, Zentreya's voice is synthesized. For reasons she keeps to herself, she doesn't use her natural voice and that's totally fine.

oh, wait, that's right, Henya got one line in, she does "So where do we feature?" in "Be Prepared".
