Firestar was one of the feature characters in the 2011 six-issue limited series Fear Itself: Youth in Revolt.At the 2013 San Diego Comic Con, it was announced that "Firestar is going to take her place as a major X-Men character for the first time" starring in the new comic book Amazing X-Men in November 2013.She was later approached by Cyclops, Angel and Iceman to join the X-Men.She accepted and was seen helping them against Magneto and the Sentinels.After the special Firestar one-shot issue (April 2010), Firestar returned to full-time superheroics as a character in the short-lived comic series Young Allies.Firestar appears as a main character in the I Am an Avenger comic book mini-series.
This story takes place shortly after up-and-coming hero Firestar becomes a founding member of the New Warriors.
The Firestar four issue mini-series depicts events both before and after Firestar's appearance in Uncanny X-Men #193, showing her development from a shy, insecure girl afraid of her developing powers to a confident young woman capable of easily defeating Emma Frost.
The mini-series also established that Firestar's powers were microwave-based, rather than the more common fire-generation power that her animated counterpart displayed; the comic-book Firestar essentially harnesses ambient microwave radiation from her environment, making her powers far stronger in an environment such as space, where the concentration of microwaves is much greater than within a planetary atmosphere.
Despite the mini-series' efforts to flesh out the character, Firestar was not featured in any stories for a few years and seemed destined to fade into obscurity until she joined the New Warriors.
She would go on to appear as a regular character in Avengers, and the informal all-female team "Marvel Divas".
The animated series and the one-shot Spider-Man and His Amazing Friends comic book (which adapted an episode for print) are not considered part of standard Marvel Universe continuity.
