It could start with Tony Stark calling everyone to the common room to check out this new trailer. 'Hey, guys, we've got to see this. It's the new Captain Marvel!' he'd say. Everyone would gather around, some with snacks in hand.
Another fanfiction idea could be a prequel to her role in Avengers: Endgame. It could show what she was doing in the cosmos just before she received the call to return to Earth. Maybe she was facing a different threat that was related to Thanos in some way, and this backstory could add more depth to her character in the movie.
She could simply overpower Thanos. Captain Marvel has shown incredible strength, so she might be able to directly take on Thanos and win in a one - on - one fight, preventing him from snapping his fingers.
Tony Stark would likely be his cocky self, making witty remarks about the Venom trailer. He might say something like 'That symbiote looks like it needs an upgrade in the fashion department.' Steve Rogers, on the other hand, would be more serious, perhaps seeing it as a new threat to protect the world from.
It could be a powerful alien warlord who has set his sights on Earth. This antagonist might have an army of powerful minions and technology that rivals Captain Marvel's and the Avengers' combined powers.
They would be shocked. The trailer might show new and powerful enemies that they haven't faced before. For example, Thanos looks really menacing. Some of them would be excited to see their new powers or weapons on display. Captain America might be thinking about how to lead the team better against these threats. And Black Widow would be sizing up the potential new allies or enemies in the trailer.
Annihilus could be a likely villain. He is a powerful being from the Negative Zone. In the fanfiction, Annihilus could be drawn to Earth because of the energy signature created when the Avengers and Captain Marvel meet. He sees Earth as a prime target for conquest. His powerful cosmic control rod gives him an edge in battle. The Avengers and Captain Marvel have to quickly learn about his weaknesses and use their combined powers to stop him from destroying Earth and spreading his reign of terror across the universe.

Captain Marvel and Thor make an interesting pairing. Their powers are both related to cosmic elements, with Captain Marvel having her energy - based abilities and Thor his godly powers.
