The story where he first gains his powers is a classic. It's a great origin story that sets the stage for all his future adventures. We see young Billy Batson transform into the mighty Captain Marvel, and it's really inspiring. It shows how an ordinary boy can become a superhero, which was a really novel concept at the time.
There's a story where Captain Marvel battles an ancient evil from another dimension. This story is filled with action and adventure. Captain Marvel has to use his wits as well as his super strength to defeat this otherworldly foe. It really emphasizes his role as a protector of the Earth from all kinds of threats, whether they be from Earth or beyond.
It depends. Marvel Unlimited has a collection of Golden Age comics, but not all titles from that era are included. You might find popular and significant ones, though.
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.
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.
I don't think so. The concept of 'strongest' is relative in the Marvel universe. Different heroes have their unique powers and moments of greatness, so it's not a straightforward answer to say Captain Marvel is the strongest.
Yes, Captain Marvel is definitely a significant character in Marvel Comics. She has her own storylines and plays an important role in the Marvel universe.
