Battalia, known as Penne in Japanese media, emerges as a pivotal figure in Team Freedom, debuting in the fifth episode. Orphaned by bandits in her youth, she escaped to an orphanage with her scorpion-type Zoid, Scorpear—also named Needle. As the oldest orphan, she adopted a protective role, sustaining the home through bounty hunting. Her proficiency in stealth and ambush tactics, amplified by Scorpear’s capacity to paralyze foes, proved lethal in coordinated strikes, though she faltered against larger Zoids in open combat.

Compelled by the Dark Metal Empire’s Numb-Lock, she accepted a perilous pact: secure 100 bounties to guarantee the orphanage’s future. Her final target, Arashi—a comrade from Team Freedom—tested her resolve. Intending betrayal, she instead turned on the Empire, securing Scorpear’s Zoid Key and severing ties with her manipulators.

A clandestine mission to undermine Team Freedom exposed her fractured loyalties. Cornered by Arashi and Analog during a confrontation, she grappled with survival versus allegiance. Deploying Scorpear’s venomous stinger against Arashi’s Wild Blast, she incapacitated both with a soporific toxin, fleeing the fray and discarding her Empire badge—a definitive renunciation of her past.

Her dynamic with Arashi oscillates between rivalry and camaraderie, rooted in shared respect. The orphans’ welfare anchors her choices, initially binding her to the Empire and later fueling her redemption. She further cemented her legacy by crafting Team Freedom’s emblem and bestowing its name, showcasing ingenuity and leadership.

While less adept in direct combat, her technical mastery in Zoid modification and tactical deployment of Scorpear’s capabilities rendered her indispensable. Evolving from a shadowy mercenary to a steadfast ally, her journey culminates in prioritizing familial bonds over personal ambition.
