Cherno Alpha was my favorite.. she had a good run I suppose. Pretty tough, took 2 Kaijus to finally bring it down. Crimson Typhoon's presence was a bit more brief, and you might feel that it was underused. At that point in the film, though, they make it clear that these new Kaiju are bad mothers, and they've also never had a double event with 2 of them.
I bought it that they were badasses, protecting their home countries for years. It kind of made it harder to watch them just get stomped.
Expect some incoming Cherno fan art from me later, damn straight.
