Metafictional Manipulation – The ability to manipulate the line between fiction and reality. This is presumably a power all creators of fiction have.
Literary Critique of Metafictional Manipulation
Stan Lee is the creator of many of the characters of the Marvel Universe.
Sometimes characters go beyond having awareness of the fourth wall but break the fourth wall and try to manipulate events and/or objects beyond the fourth wall.
Deadpool (Marvel) gets some very powerful metafictional tools from Galactus in What If V9 #1.
Mephisto (Marvel) has a very long combination with the readers and thinks they will meet again as shown in the Infamous Iron Man #12 (2017).
Superboy Prime (DC) talks to the reader in Final Crisis: Legion of Three Worlds #5.
Death Rattle V1 #1 (Kitchen Sink)
Bunko the Dog appears in America’s Best Comics Special Giant (2001).
Captain Justice V1 #1 (Marvel)
Creepy Yearbook (1969)
The Droste Effect – Is a cover within a cover. I consider a cover of with this effect to be inherently self-referential and therefore an example of metafictional manipulation for artists who would never consider a plot line that was self-referential. The Droste Effect is an example of cookie cutter metafictional manipulation. Since the cover occupies a central position in comic book fiction this effect can be very powerful.
