Marvel's Thunderbolts and Captain America: Brave New World – Fresh Trailers Unveiled

Marvel Studios also had a strong presence at D23 Brazil, showcasing new trailers for upcoming projects that are sure to get MCU fans buzzing.

Captain America: Brave New World: New Glimpses of Red Hulk and Sidewinder

The much-anticipated Captain America: Brave New World gave fans a closer look at its star-studded ensemble and new villains. Harrison Ford, who joins the MCU as Thaddeus “Thunderbolt” Ross, is seen in his role as Red Hulk, a character that has been teased for a while. The trailer also revealed a glimpse of Giancarlo Esposito as the mysterious antagonist, Sidewinder, leaving fans eagerly awaiting his confrontation with Sam Wilson’s (Anthony Mackie) new Captain America.

The film’s poster was also revealed, giving us a better sense of the movie's tone and visuals. Fans are excited to see how this new chapter in the Captain America saga will unfold, especially with the addition of Ford’s iconic character.

Thunderbolts: New Misfits Take Center Stage

In another highly anticipated reveal, Marvel released an extended trailer for Thunderbolts, the upcoming film that brings together a new group of antiheroes. The trailer showcases the various characters, including Florence Pugh as Yelena Belova, Sebastian Stan as Bucky Barnes, David Harbour as Red Guardian, Wyatt Russell as US Agent, and more. The dynamic between these flawed characters promises to deliver plenty of action, humor, and conflict.

The extended trailer highlighted the chemistry between the misfits as they come together for a mission, and fans are eager to see how these characters, many of whom have previously been introduced in other MCU films, will come together in this ensemble film.

Marvel also revealed a cinematic poster for Thunderbolts, teasing the tension and drama that will unfold among this new team.

Miles Morales in the MCU: Updates on Spider-Man’s Future

One of the biggest MCU updates from D23 Brazil came directly from Marvel Studios head Kevin Feige. Feige confirmed that Miles Morales, the fan-favorite Spider-Man, will make his live-action debut following his appearance in the Spider-Verse films.

However, fans may need to wait a bit longer for Miles to swing into the MCU. Feige confirmed that Miles will first appear in the upcoming Spider-Verse film, Spider-Man: Beyond the Spider-Verse, which is currently facing delays. The live-action debut of Miles Morales is expected to happen shortly after Spider-Verse 3, potentially around 2027. While fans are eager to see Miles in live-action, they’ll need to be patient before his official MCU introduction.

X-Men’s Storm Coming to Disney+ in What If...? Season 3

Another exciting announcement from Marvel was the confirmation of Storm’s debut in the What If...? animated series. The veteran X-Men member will appear in Season 3 of the popular Disney+ series, which explores alternate realities and “what if” scenarios within the Marvel multiverse. This marks an exciting step for X-Men fans, as Storm’s appearance in the MCU has been highly anticipated, especially as the mutants are expected to make their live-action debut in future Marvel films.

The Road Ahead for Disney and Marvel Fans

D23 Brazil has given fans plenty to be excited about, from new updates on Avatar 3 to thrilling trailers for upcoming Marvel films. With new characters, expanded universes, and exciting plot twists on the horizon, both franchises are poised for even more success in the coming years.
