Beatriz Bonilla da Costa, known as Fire, is a prominent superheroine in DC Comics, recognized for her pyrokinetic powers and Brazilian heritage. She first appeared as Green Fury in Super Friends #25 (October 1979), created by E. Nelson Bridwell and Ramona Fradon, establishing her as one of the earliest Latin American female superheroes in mainstream American comics. Her integration into the primary DC Universe occurred in DC Comics Presents #46 (June 1982). As a former operative for the Brazilian government, da Costa acquired her abilities following exposure to an experimental pyroplasm substance during an explosion, which permanently turned her hair green and enabled her to generate and manipulate green flames, transform into a plasma-like fiery form, fly, and project powerful energy blasts.

Early in her career, Fire served as a member of the Global Guardians, an international team of superheroes, initially operating under the aliases Green Fury and later Green Flame. After the team's dissolution in the wake of broader DC Universe events, she joined the Justice League International in 1987, adopting the name Fire and forming a close partnership with Ice (Tora Olafsdotter). The duo became iconic during the lighthearted and critically acclaimed Justice League International era, where Fire's passionate, outspoken personality complemented Ice's calm demeanor, contributing to memorable team interactions amid global threats and comedic scenarios.

Over subsequent decades, Fire's narrative incorporated deeper personal and power-related challenges, including a stint with the espionage agency Checkmate as the Black King's Knight. She endured significant developments, such as temporary loss of control over her abilities, leading to a phase as a pure energy being before restoration. In The New 52 continuity, she appeared as a member of the reformed Justice League International but was gravely injured early in the storyline, limiting her involvement. Fire has maintained a recurring presence in various DC titles and adaptations, embodying themes of cultural representation, friendship, and resilience.
