Captain Marvel is Carol Danvers. She gained her powers through an interaction with alien technology and has become a powerful hero in the Marvel universe.
In the first 15 minutes of Captain Marvel's story, we are introduced to Vers. We see her on the planet Hala, training with the Kree. She has some flashbacks that hint at her past, but she's fully committed to being a Kree warrior at this point. We also get a sense of the Kree's military - like atmosphere and their technology.
The debut Captain Marvel graphic novel comic book was 'Marvel Super-Heroes #12'. It marked the beginning of the character's adventures in this format. Over time, the series has evolved and gained popularity.
One idea could be a story where Captain America and Captain Marvel team up to face a new cosmic threat that's headed towards Earth. They have to combine their unique skills, with Captain America's strategic mind and combat experience on the ground, and Captain Marvel's incredible cosmic powers in space battles.
