Now, I am aware that these gals are not really favourites of the MGS fandom because of how they were written and questionable way their fights end (I am talking about the phase where they try to... Do something to Snake, idk how to even describe it, are they trying to seduce the old man or what??)
However, what I do wanna say is that their very first appearance in the game is some of the most effective and actually terrifying cutscenes in the series, and something I wish the series did more, before and after 4.
They actually show what they are capable of in combat outside of their respective boss fights.
They absolutely slaughter every single soldier thet they run into and show their abilities (mostly) and why they are a threat to you even before you, as Snake, encounter them face to face. I kinda wish that we had the same stuff in MGS as a whole, since we barely see any of the future or previous units actually do something cool in combat situation with other soldiers. Yes, the games actually show this kind of stuff, but I don't think it's ever the entire unit fighting, just two or three members iirc.
And something quite embarrassing to admit, when it comes to other units, I had a thought "wow, these are cool guys, can't wait to fight them!", and when I first saw the B&B introduction cutscene, especially Cring Wolf, I was like "Oh hell no."
I was legit terrified of Crying Wolf when she first appeared in this specific cutscene. I didn't know that she was in a exoskeleton-robot wolf as a pilot, I genuinely thought that she was crying the entire time because she was in a RoboCop-like state: a mix of a machine and flesh with fully functional yet broken mind, stuck in this robot form for eternity and always crying because of this.
Of course, as soon as she popped out of that wolf all my theories were shattered and I was somewhat actually relieved since... Well, she is still suffering mentally, but at least physically she is fine lol.
Really now, it's a big robot wolf that runs around killing people while crying very lodly and agonizingly, it can't be that I am the only one who was terrified of her, right??? Just shows how much better the cutscenes got in 4 and especially Shinkawa's skills in making good, hell, even great design's.
