After the destruction of Kashgar Hive, a full plan to clean sweep the remaining hives on earth is initiated. Unknown TSFs sighted in battlefield either affiliated by a country or some of them are mercenaries sporting new tech from companies.
Type-97U Fubuki an upgraded version from Japan, equipped with thruster on legs powerful enough to make critical turns its armaments consist of large caliber automatic rifle with bipod and long barrel(long barrel can be disengage for high rate fire and close range combat), type 65 PB knife, and type-74 PB short blade. Cockpit is improved thanks to the XM3 OS now you can pilot with just pajamas and do a barrel roll as much as you want.
The YF-23 "Lone Wolf" is a heavily modified YF-23 Black Widow II which is bought by a distinguished rivaled Company. The development started in Alternative IV timeline, their goal is to make an energy type TSF to once again dominate the sky also it should be able to use laser type weaponry, impressive speed than a normal TSF while in the surface, and a flight ability at high speed to avoid laser class BETA. The company didn't produce the unit as it cost a multi-billion dollar but the data they gathered will be useful for their future production of TSF. Only one unit is made and currently on testing phase somehow the result is satisfying unless the Lone Wolf is tested in real combat against BETA.
I decided to create one, most of the TSFs are obviously good enough to fight BETA or TSF one exception to BETA is, just like what Prophet said "Not just New York. Not just Lingshan. The Ceph have been around... forever, man.", they're just too damn many to handle.
