Warbird responds to Agent X's request with a personal history lesson.
"I entered the Air Force after graduating high school to pursue my love of aircraft and my dreams of flying. I was a top student at the Air Force Academy and eventually rose to the rank of Major before being recruited into the intelligence field, where I met Nick Fury. After that, I took a position with N.A.S.A. as the security director for Cape Canaveral, which is where I first met Captain Mar-Vell, the Kree warrior. I was charged with unraveling the mystery of this alien soldier until his enemy, Colonel Yon-Rogg, kidnapped me to use as bait against Mar-Vell. In the course of the battle, Mar-Vell and I were caught in the explosion of a Kree Psyche-Magneton device. The energy bombardment somehow caused my genetic structure to be melded with Mar-Vell's, making me a perfect hybrid of Kree and human genes. Through this transformation, Ms. Marvel was born.
Eventually, I...moved to San Francisco and battled Rogue, from the Brotherhood of Evil Mutants. She absorbed my powers...my memories...my personality...Charles Xavier helped me recover for a while...and later I ended up with the Avengers...I call myself Warbird now. Convenient, since that new girl with the Fantastic Four seems to be using the Ms. Marvel moniker now. So here I am. What's your story?"
Agent X can tell that several of Warbird's pauses were intended to cover periods in her past she'd rather not discuss. Apparently, she has some pretty painful memories she's rather not revisit.
