The tagline from Marvel reads “A Long Awaited Return….” while the quote on the teaser itself reads “I knew this was my chance to be a hero.” The image shows a simple gold cross star emblem and with the Avengers: Standoff stamp below it. With very little to go on, thanks again Marvel for allowing us to theorize.
First we have to notice the focal point of the image, the cross star, this could be one of three symbols:
Nova: Currently Richard Rider was last seen in the Cancerverse after sending Star-Lord back home and Thanos hitching a ride with him. Rider is also a fan favorite and fits the “A Long Awaited Return….” tagline. The Nova star symbol is usually red, and has multiple points.
Captain Marvel: Mar-Vell died but has been brought back and teased in many ways over the years. The current Captain Marvel is Carol Danvers and with a movie coming and Marvel being big on diversity I doubt they will be bringing back Mar-Vell, despite how well liked he is. Then again they could be bringing him back to go along with the Captain Marvel movie to tie it in with Carol’s origins, but I still doubt it. Mar-Vell isn’t the only Captain Marvel that could be returning since his son Genis-Vell is also gone at the moment and could be returning. Then we have Rick Jones who was once Captain Marvel, and is a part of Avengers: Standoff. But like the Nova star the Captain Marvel star is a bit more detailed with more points in it.
Quasar: Wendall Vaughn, Phyla-Vell, and Richard Rider all took on the mantle with Wendall Vaughn being the most known as Quasar. Giving that currently they are all gone they all fit the return aspect but only one I think would fall under the “A Long Awaited Return….” and that would be Richard Rider, who is a fan favorite. But there are two other factors to work into the equation, the quote “I knew this was my chance to be a hero.” and the Avengers: Standoff stamp, they could point to Wendall Vaugn who was an Agent of S.H.I.E.L.D. before he took on the bands and became Quasar. Out of all the star symbols this most resembles that of Quasar.
