This is probably the one movie with the most on-screen animated Transformations I've seen in a while. The male ones are literally everywhere, the female ones start occurring from half the movie onward. I will try to list them as best as I can
Around 56 min , the protagonist's wife turns into a body-horroresque half monster.
Around 59 min, the protagonist's daughter becomes quickly a muscly monster.
Around 3 or so minutes later, Bem goes out and many civilians turn into those same monsters, one of them being a lady.
Around 1h 15-20 mark, the main female monster turns offscreen into her monster form, and instants later a female villain turns onscreen into another kind of monster.
Tell me if I missed anything
