*Mira Fermin (ミラ・フェルミン, Mira Ferumin?)[2] is the 16-year-old Vestal leader of the Bakugan Battle Brawlers Resistance and a Subterra brawler. Magma Wilda is her Guardian Bakugan and she uses Baliton as her Trap Bakugan.

She was the daughter of Vexos scientist Clay Fermin and is the younger sister of Spectra Phantom. When she first played Bakugan, she thought of them as just feral creatures. That was until she witnessed Alpha Hydranoid, while being tortured, speak out in vengeance. It was then that she realized that Bakugan were alive, so she formed the Resistance with Baron Leltoy and Ace Grit.

She is one of the main characters in Bakugan Battle Brawlers: New Vestroia and a supporting character in the second arc of Bakugan: Mechtanium Surge.

Mira's height makes her look young, though she is 16 years old. She has short orange hair, large busts, wears a small silver jacket, white gloves, blue earrings, has sapphire blue eyes, and wears a rouge jumpsuit with uneven sized boots and leggings. She sometimes wears a yellow helmet with her matching motorcycle and a locket with a picture of her brother inside.

In Bakugan: Mechtanium Surge, Mira wears a white track jacket with blue stripes over a blue dress, as well as a black collar. Her hair is slightly longer and she wears lipstick.

Mira's personality can be described as a stubborn tomboy, much like Runo Misaki. Mira has shown that she could act girly, when she fooled some guards by acting like a crazed fan girl while she, Baron Leltoy, Dan Kuso, and Marucho Marukura were looking for the Dimension Controller in Alpha City. She could also be flirty when she wanted to be as shown the day she saw Alpha Hydranoid being tortured when she flirted with the guards at her father's lab.

She will do anything to get her brother back, even if it means going off on her own and getting in danger. It is because of her desire to find her brother that she gets into fights with Ace a lot, like Dan and Runo do.

As the Resistance's leader, Mira always tries to get the team moving. She's the one who pushes Baron to battle strong and also attempts to get things straightened out whenever the group gets into an argument.

Mira as also shown to feel empathy even towards people who have wronged her as despite the many crimes Spectra Phantom had committed, she still felt bad when Spectra mentioned how Gus had died fighting Zenoheld. She also felt sad for Gus when he presumingly died even though Gus treated her awful throughout the second season. She was even willing to forgive Mylene and tried to save her from being sucked in (despite the fact that Mylene tried to kill her using Macubass) which sadly Mylene did not except.*
