Created by writer Bill Mantlo and artist Sal Buscema, the character first appeared in Incredible Hulk vol.

She joined with other Southwestern heroes (forming a team called the Rangers) and fought the Corruptor, rescuing Rick Jones in the process, who had actually sent the signal.

[15] She assisted the Avengers during the following adventures, and desperately wanted to be invited to join, something to which chairman Hawkeye remained oblivious, since he was trying to recruit the Thing.

[20] Eventually, she reappeared as La Espirita and arrived in the nick of time to stop Hank Pym's suicide attempt.

She assisted Hellcat, Monica Rambeau, Moondragon, and Black Widow in subduing the Awesome Android,[28] and encountered a small platoon of Atlanteans in Mexico getting help from a few Avengers.

[30] Her immunity to radiation later made her indispensable when a mysterious energy field engulfed a small Russian country and turned everyone into zombies during the first blows of the Kang War.

[31] When Captain America is briefly transformed into an energy zombie, Thor, briefly believing him dead, begins to fear that he has become too close to his mortal comrades despite his knowledge that he would outlive them when forced to face such vivid evidence of his allies' mortality, and contemplates leaving the Avengers after the war was over.

In recognition of her advice, Thor toasted her when he arranged for Asgardian cooks to prepare a feast for the Avengers to celebrate Kang's defeat, commenting that she had taught a god a lesson by treating him as the fool he was.

Captain America's dialogue implies that the new members, including Firebird,[34] are registered heroes who have nonetheless turned against Iron Man's forces because of the Bill Foster debacle.

Weeks after the conclusion to the Civil War, Firebird is seen as one of the members of the revived Rangers, as part of the 50 States Initiative Program.

[36][37] The Rangers come into conflict with Kaine, alias Scarlet Spider in Houston,[38][39][40] then they joined forces with him to battle a monster made of pure energy.

[39][41] Bonita Juarez acquired a range of superpowers due to bombardment by radiation from a meteorite containing energy waste from an alien's scientific equipment.

She can channel her powers through her hands to seemingly project searing thermal blasts from her body (actually from her mind), capable of melting steel.

[45] Firebird also seems to be immune to most forms of radiation and poison (and even demonic possession) as well as the physical effects of her mental powers, and has displayed the ability to survive in the vacuum of space.

Jason Wiese of CinemaBlend asserted, "Firebird is one of the most popular and important female Marvel superheroes of Latin origin.
