Test pilot for "Lone Wolf" she's only known as Frost Thunderstrike ironically matches her cold determined personality who follows every mission without any question, her piloting aptitude is incredibly off the chart with every TSF she pilots. She is able to take down hostile target at extreme distance with just a few burst of an assault gun. Frost is hired by the Company because of her talent and she's not affiliated with any government or military force.
I thought F-4 Phantom or Gekishin is a good machine, its rather heavy and suffers from poor mobility and the first generation TSF, but I like the design it reminds me of something. I made a little changes to them so they're no longer called Gekishits.
