Fire Soul Bird is a flame technique used by Sailor Mars and a direct evolution of her Fire Soul, distinguished by fire that strikes in the form of a bird. It surfaces only in the 1990s anime and a handful of tie-in games, with the DiC dub renaming it Mars Firebird Strike.
Fire Soul Bird is a burning technique cast by Sailor Mars and a straight evolution of her Fire Soul, set apart by flame that attacks in the shape of a bird. It shows up only in the 1990s anime and a few tie-in games. The DiC English dub retitled it Mars Firebird Strike, and its Japanese name reads Faiyaa Souru Baado.
The avian form nods to the fenghuang, the phoenix of Chinese legend said to rule over every other bird. That eastern creature stands apart from the western phoenix rooted in Egyptian myth, though both traditions tie the bird to imperial power and heavenly favor.
Mars readies the move much as she does Fire Soul, chanting while she holds an ofuda before her. She hurls the paper charm, shouts the attack's name, and looses a fireball from her index fingers. The flames swallow the ofuda and stretch into a phoenix-like form. In the Viz Media dub she recites a different kuji-in incantation than the one preceding Fire Soul.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

There are no women on Namek. That isn't an oversight, it's the biology. Why we handed Piccolo the one thing his own species rules out, and why it had to be trap soul....
Sailor Mars is the sole user. Her first casting came in episode 54 against the Cardian Siren, who had shredded her music sheets; an ordinary Fire Soul failed when Siren's water doused it, so the upgraded bird tore through the water and destroyed the enemy, freeing all the energy it had gathered. She reached for it again in episode 59 against Ail and An, this time without chanting, and the weakened version could not pierce the aliens' shields.
Across games the technique appears in Sailor Moon R, in Sailor Moon: Another Story where it strikes multiple foes for four energy points and feeds the link routines Fire Dragon and Love-Me Bird, and in the S fighting title Jougai Rantou!? Shuyaku Soudatsusen.
Fire Soul Bird is a fire technique used by Sailor Mars and a direct evolution of her earlier attack, Fire Soul. It is distinguished by flames that take the shape of a bird as they strike.
Sailor Mars chants while holding an ofuda charm, then hurls it and releases a fireball from her index fingers. The flames engulf the ofuda and stretch into a phoenix-like shape as they fly toward her target.
Fire Soul Bird debuted in episode 54, when Sailor Mars used it against the Cardian Siren after an ordinary Fire Soul failed to work through the enemy's water.
In the DiC English dub, Fire Soul Bird was renamed Mars Firebird Strike.
Fire Soul Bird eventually gives way to Sailor Mars's stronger technique, Burning Mandala.
