Just in time for International Women’s day, Captain Marvel is making her debut. However, the arrival of her awesome trailer resulted in a series of questions for those who are casual MCU fans. Who is Captain Marvel? What does she do? How will she help save the Avengers? Well here’s a short rundown of what’s going on.

Carol Danvers, a former Air Force pilot with hopes of working for NASA, finds herself in trouble one night. Working as a NASA security guard to investigate the sudden arrival of Kree and Skrulls, she gets caught in the middle of a battle between Mar-Vell and his nemesis Yon-Rogg. Now exposed to a certain Kree technology called Psyche-Magnitron, which turns the imaginary into reality, she finds herself with powers similar to that of Mar-Vell’s.  Those powers include flight, superhuman strength, and energy blasts.

Dealing with the aftermath of having her DNA rewritten, she tries to put her powers to good use by fighting alongside her mentor, Captain Mar-Vell, and making a name for herself as Ms. Marvel. It wasn’t until the tragic death of Mar-Vell that she took the title of Captain Marvel as a tribute to her friend.

She also adopts her cat sidekick, Chewie, who happens to be Flerken (An alien breed that looks like cats). She goes on to have many adventures, both in space and on earth.  She also helps out the X-men and Avengers in a few issues, going on a tiny love crusade with War Machine for like, five seconds before he dies. It’s no question that Marvel Studios knows she’s powerful enough to defeat Thanos, maybe not as powerful as Squirrel Girl, but still very, very powerful.
