One of the reasons I wanted my villain to have some form of omnipresence or something that's consistently seen by the viewer.
After going through multiple fantasy books of different genres and some of the best works, I've noticed a pattern that every single villain or an idea is always present. It's like a subtle reminder.
A great example of this is the wolf from puss in Boots.
The wolf barely has any scream time in the entire movie and only shows up near the very end and it's the climax of the entire movie.
In almost any other scenario that little time to introduce the character and barely any time on the screen wouldn't really pay off.
But I think the reason why it's paid off so well is the idea of the wolf always being present because of the whistle and the association with death, it's an omnipresent force that is a constant reminder and motivator.
Another great example of this is dystopian novels with the government. I think that's why they're so enticing, is because of an omnipresence of these ideas.
It's also explains our obsession with supernatural beings or creatures that can be found around different cultures, it's the omnipresence of these items or phenomenons in everyone's life.
