These latinas are, please excuse the dreadful cliche, "hot"

Fire - Firebird

In which prominent Latina super heroines with fire-based powers are paired with one another. And apparently brazilians can, despite not being recognized as such by the U.S. Census, be classified informally as “latino.”

Commonalities:
Both characters bear Latin American roots and have fire-based abilities…

Differences:
…but Fire physically becomes flame, whereas Firebird manipulates said element. And Fire is a tempestuous Brazilian hedonist (a stereotype, natch), whereas Firebird is a very religious Mexican American.

Alternate histories:

FI: Beatriz da Costa is a young Brazilian-American woman who encounters and is altered by a radioactive meteor in a desert in the Southwest: she is thus imbued with the ability to transform herself into a being of pure flame. She assumes the codename Green Flame and then simply Fire and soon joins a West Coast expansion of the Justice League. Fire has served therein occasionally while working as a social worker.

FB: Bonita Juarez is a young Mexican model who finds herself as an agent of that country’s secret service; she encounters and is altered by a pyroplasmic explosion that grants her pyrokinetic abilities. Taking the codename Firebird, Juarez joins an international organization of super-heroes and later an global iteration of the Avengers. Firebird has since worked as an agent of the international intelligence agency SHIELD and with the Daughters of the Dragon.
