Hometown: Pallet Town (Kanto)
A hotblooded trainer on both the competitive circuit, as well as Pokéthlon events, Fira was always eager to impress her friends and family, as well as show up her little brother. She spent a few years climbing the ranks in the Battle Tower of Hoenn, but immediately came home upon seeing her little brother somehow becoming the champion of the Kanto Region. How did the little squirt manage that so quickly?
Growing up, Fira adored her starter Pokémon Cyndaquil, always flaunting her to her little brother before he got his Charmander. Becoming a mainstay of her team as a Typhlosion, it was soon joined by her Litten, a Pokémon with a massive ego that's reckons it can take a whole horde of Pokémon at once. which is probably true when it enters its Gigantamax Form. Both Pokémon serve as powerhouses for Fira's specialist team, though despite the sibling rivalry of Fira and her little brother, the two Fire-types get on really well with Houtaru's Charizard.
As for the rest of her Specialist team, her Scovillain is more of a menace, often spraying nearby trainers Pokémon with its spicy spray, while her Cylizard joins the fire-type focus with its terastallization, and is also a mainstay of her side hustle as a Pokéthlon star. Her orange-flamed Chandelure is a eery phantom, unleashing phantasmal flames to tear through the competition, and her Turtonator will unleash explosive force on any Pokémon that comes too close.
As for her freeform team, her Empoleon was always prideful, even as a Piplup, always puffing up his chest to imprint its importance, and has a one-sided rivalry with Houtaru's Sceptile. Similarly, her Drapion has a rivalry with Houtaru's Lokix, though in this case, Houtaru's Lokix see's Drapion as the villain to its heroic masked rider. And then falls to Fira's Grimtaceous to end the conflict between the two sibling's teams... and often the two siblings themselves. Fira's Haxorus is an aggressive striker, slashing opponents with its axe-like tusks, while her elegant Togekiss bombards opponents with Aura Spheres and Moonblasts. And her Aerodactyl is a violent Pokémon, only listening to Fira herself. Must've been a hell of a job, since she somehow developed a bond strong enough with it to allow it to Mega Evolve.
So with her little brother being Kanto's champion, of course she made a beeline to Akkadios with her boyfriend Silas as soon as she heard Houtaru would be entering the Pokémon World Tournament to knock him down a peg or two. After all, what are siblings for? And she's certain she's winning that particular match-up if it comes up.
