In Thunderbolts*, there was a new Marvel Studios logo that combined elements from the 2013 logo (flipping comic book pages and panning) with the design of the 2016 logo.
Thunderbolts* had a variant of the new logo with the comic book pages showing Yelena Belova, Red Guardian, U.S. Agent, Bucky, and the Sentry, but then the logo got consumed by the Void, with the music fading out one-by-one, causing the logo to look black on a black background. Will the Phase 6 movies do something similar to Thunderbolts*?
For example, The Fantastic Four: First Steps will likely have the comic book pages show the Fantastic Four, the Silver Surfer, and Galactus, and the background will be blue, Avengers: Doomsday will likely have the comic book pages show Doctor Doom and the background will be green, Spider-Man: Brand New Day will likely have the comic book pages show Spider-Man and Venom, if Blade is part of Phase 6, it will likely have the comic book pages show Blade, and if Armor Wars is part of Phase 6, it will likely have the comic book pages show War Machine and pages from the Armor Wars story arc.
