My favorite character is indeed Don Bruno FNAF, because he is goofy but becomes serious when he needs to be. The nonsensical things he says and the constant back-and-forth between their waifus—Juninhjo being Pinkie Pie and Bruno being Chica—are hilarious. Also, their justification for consuming clop or FNAF porn is funny as hell XD. But yeah, Bruno was a gold-tier villain, and the stoner guy from South Park was pretty funny as well.

Update: My idea is that “moral” refers to an individual, not an abstract concept. In other words, it represents the victorious superior—similar to the internet labels “chad” or “swag” from the early 2000s. It signifies someone who is ired, feared, and holds high status—a person with a history of being a “badass,” someone who succeeds in everything they do.
That’s what “moral” signals in this context. So, the title The Great Moral isn’t a concept but rather an individual—someone highly regarded as “moral,” possessing the power and authority to command, invoke fear, and earn respect from others. However, this title is never absolute—it can always be challenged, and it can be lost.
I guess the characters in the movie are trying to personify The Great Moral in their fight, or at least prove that their mafia (fandom) is superior and commands the others.
