Favourite Group of Bosses?

I'd say FoxHound. They're a pretty good five man band. They interact with Snake well and all have some memorbale backstory with the exception of maybe Raven. He's probably the weakest link and even then, I can still think he's memorable. Wish we'd seen more of the shaman side to go with the big guns though. 

Dead Cell is fine. Fortune and especially Solidus do a lot of heavy lifting for them. Fatman is just an annoyance responsible for my second least favorite part of MGS2: running around Shell 1 defusing bombs. Vamp is okay.

Cobras as characters are pretty dull. The Pain and Fear especially. The Sorrow, who's literally dead, is more interresting. Now I will say they had great boss fights, especially The End and the rest onward so gameplay wise, best so far.

Still haven't played PW or MGS4 (stop being a PS3 exclusive!) so onto PO.

FOX is better than it has any right to be, probably because it has so many throwbacks to Foxhound, like being the protagionist's older squad. Gene is supposed to be a successor to The Boss and has to fight the other successor (Solid/Liquid dynamic), the torture expert is second in command and has his own agenda and is planning on betraying his boss, there's a psychic on the squad, a guy who likes the cold you have to play hide and seek with in a frozen room. I do like how they interact with Big Boss. I wish Python had a bigger role in the game if you recruit him. 

I haven't pleyed MGR since like 2014 or so, so I won't comment on Deaperado. Anytime I see MGR referenced, it's usually Armstrong since he's an over the top meme machine.

The Parasite Unit are just harder enemies that look more menacing.
