Marvel.com unveiled this teaser heralding Captain Marvel in July 2012. All will be revealed Saturday, March 17 at the Talk To The Hat panel, 4:00PM PST, during WonderCon 2012.
An earlier preview for the cover of Secret Avengers #27, the AvX tie-in showed Captain Marvel bursting out of what appears to be Phoenix energy and flanked on each side by Ms. Marvel and Protector.
Could this mean the entity of death and rebirth could give birth to a resurrected Mar-Vell?
