The teasers for Avengers: Doomsday and Spider-Man: Brand New Day have leaked. While the Avengers ones have probably leaked due to their attachment to Avatar: Fire and Ash, Spider-Man’s leak is a breach that has Sony copyright striking any whiff of posted material.
Four different teasers for Doomsday are planned to play in front of Avatar: Fire and Ash with a different one playing each week.
The first Doomsday teaser seemingly confirms the return of Chris Evans. He is shown riding a motorcycle, looking at his Captain America uniform, and holding a baby. The teaser ends with a confirmation that Steve Rogers will return to Doomsday.

The audio for the Thor teaser is allegedly out there. Audio descriptions purport it supposedly being Thor praying to his father Odin and wanting to return to his daughter, Love.
The third teaser is purportedly going to be about Robert Downey Jr’s Doctor Doom while the fourth and final teaser will be a proper teaser trailer.
The Spider-Man teaser leaked from a marketing research app. It has Peter Parker acknowledging him being wiped from people’s memories from the last film, Sadie Sink threatening Peter Parker, and appearances from Mark Ruffalo’s Bruce Banner and Jon Bernthal’s Punisher.
