Penne

ペンネ

Also known as Battalia in the English dub.
Arashi meets Penne in episode 5, and following the events of that episode, Penne joins Team Freedom. Penne significantly re-names the team to "Freedom" and designs the logo, a substantial improvement over Arashi's attempts at a name and logo for the team in the previous episode.
Penne has a sordid background. Her parents were killed by a group of bandits when she was young. This forced her to flee to an orphanage with her Scorpear. Being able to ride Zoids, she took up bounty hunting. She was quite successful, even capturing the bandits that had attacked her parents. Eventually, she hears of the Death Metal Empire, which was seeking the Wild Liger. She teams up with Arashi to gain his trust and plans to double-cross him for the reward.
She nearly succeeds, but gives up and instead double-crosses Foiegras, one of the Four Heavenly Kings of Death Metal. It is not until after turning on Death Metal that the Scorpear bestows her with its Zoid Key.
