EON recognizing that Billy Mar-Vell needs assistance in his battle against Thanoseid (and while loathe to do it*) calls forth the Eternitron Bands. Sending these to Earth so they are discovered by shy, naive Carol Batson. When she taps the bands together and utters the word "KREE-ZAM!" she transforms into The Worlds Mightiest Cosmic Warrior Maiden - Ms. Mary Marvel.
*Seems Miz-Maree is a bit of a hot tempered warrior maiden who disobeyed some orders in a previous war with Thanosied and got herself trapped in the Eternitron Bands in the first place.
Nice background story. I just wish the costume wasn't so dark..you'd figure that in the midst of a lightning strike then there would tend to be more light hitting the costume. Still a good concept.
The Cosmic Warrior Maiden who disobeyed orders, and got trapped in the Eternitron Bands is named Miz-Maree. See the asterisk/footnote in the posting text. So when Carol slams the bands and shouts "Kree-ZAM!" she changes places with Miz-Maree the Mar-Vell warrior. ;)
