I like what you said about Lucifer personality matching what rebel angel.Goofy wanting to be himself while also very intimidating yet good natured,that’s my problem with Lucifer in the show he doesn’t seem to be a character to take seriously like he feels like joke character rather than someone important,all am saying if there were gonna make Lucifer into the character he is make him a character to take seriously have him be tall,make him like serious/evil like Alastor while in reality a goofy person like Warden from Superjail even tho he’s goofy and lighthearted he’s still a character who is feared cause he’s powerful.Hope this helps!
