Well, at least in the Metal Gear universe, Khrushchev was bilingual with Russian and English (based on his call with Johnson, and its extremely doubtful the latter would know Russian). Granin's likely to be bilingual due to his speaking with a Russian accent when talking to Naked Snake, which technically wouldn't exist had he been speaking actual Russian as the game heavily implies with most of the Russian characters that Naked Snake met, which is even more likely with his interactions with Huey. The San Hieronymo Personnel are implied to be skilled in both Russian and Spanish due to their cooperation with FARC. Maybe English as well, assuming the FOX members and Roy Campbell can't speak Russian. Zadornov is implied to be fluent in both English, Spanish, and Russian (the last being his native tongue). Kaz was mentioned to be fluent in Spanish, English, and (due to being born in Japan) Japanese, and may have at least a working knowledge in French if we go by his briefing file on Bon Curry in the Japanese version. Raiden knew at least some Spanish, and may have known some French as well, the latter based on his telling Dolzaev that Mistral's last words were not directed at him. Elisa/Ursula were likely to also know German due to originally being from East Germany, maybe Russian due to their parents working at the Ural facility. Gene's likely to have known Russian and German, maybe Spanish in addition to English. Raikov might know at least some English, due to his conversation with Roy Campbell (assuming, of course, Campbell wasn't speaking in Russian). Sokolov might have also known at least some English (most likely learned in preparation for defection to America), although his conversations with Naked Snake, at least during their first meeting, were implied to be in Russian. Cecile has at least enough knowledge of English to speak with Naked Snake, though by her own admission she isn't knowledgable in it. Coldman might know some Russian based on his interaction with Zadornov. Since Amanda and Chico used Spanish slang throughout their sentences, its very likely that they know English as well. Paz, aside from knowing Spanish and English, most likely knows some Russian as well, due to her working with Zadornov as a fellow KGB agent. Strangelove might know some French, based on Cecile's admission that she's weak in terms of English and their conversations during the latter's imprisonment. Madnar's mentioned to be fluent in Russian and English, and based on his daughter's conversing with Snake in Metal Gear, she may have the same bilinguality as well. Since Holly White's mom is French, she's likely to have known French as well, plus as a CIA agent, she's likely to need to know more languages than just English to get her job done. Revolver Ocelot, besides English, is implied to be fluent with Russian as well. Mistral's likely to be bilingual in French and English. Monsoon is fluent in Chinese, Khmer, and English. Since Samuel Rodrigues is Brazilian, he is very likely to know Portugese as well as English. Vamp's Romanian, so he most likely knows Romanian as well, and since he acted as Subcommander to Outer Heaven (which has French and Russian PMCs), he likely knows Russian and French. Dolzaev and Boris fluent in Russian and English, and the former is also implied to have a working knowledge on French, based on his reaction to Mistral's last words (which were given in French). The latter might have some knowledge on Czech, due to his working with the Paradise Lost as well as being implied to have given them a job after the events of Third Sun. Psycho Mantis is very likely to know Russian due to his heritage, and assuming the claims about Decoy Octopus are true, he is a master at a dozen languages, including English, German, Spanish (likely native language due to allegedly being Mexican) and Ebonics (although that's technically not an actual language as much as an accent, but still...), and due to Sniper Wolf being a Kurdian Iraqi, she's likely to know Iraqi in addition to English. Since the Cobra Unit worked alongside the Allied Powers during World War II, its very likely they all knew English in addition to Russian. The Boss most likely knew Russian, since she taught Naked Snake the language. Screaming Mantis, depending on where in South America specifically she was raised in, might know either Spanish only or Spanish and Portugese, but in either case certainly knows English alongside those two. Since Drebin 893 and Crying Wolf are from Africa, they most likely know some sort of African language, alongside English. Raging Raven most likely knows Indonesian due to her heritage there. As far as Laughing Octopus, depending on which part of Scandinavia she was born and raised in, she most likely knows either Swedish, Norwegian, Danish, or Finnish in addition to English. Since Kevin Washington is a former UN member, he's most likely fluent in a lot of languages in addition to English. The Desperado Scientist in Mexico was clearly knowledgeable of both Spanish and English. Apparently, Code Talker knows the Navajo language, although its unknown right now if he knows English or any other languages as well. Gustava Heffner is obviously bilingual in Czech, Slovak, and English. Kio Marv, assuming the Czech Republic and Slovakia have indeed split apart just as they did in real life before MG2, most likely is fluent in both Czech and Slovak. Gray Fox knows German, English, and, assuming he chatted with the Portugese soldiers while getting them to drop their guards, he might know Portugese as well. The Gurlukovichs are very likely to be bilingual, knowing Russian, yet speaking English frequently (aside from the accents, which is a dead giveaway that they aren't actually speaking Russian, Olga and her father pretty obviously spoke English to Raiden and Scott Dolph, respectively, as neither of them knew Russian). The Pieuvre Armamant PA announcer might know both French and English, due to her speaking with a French accent. Basically, if a character is speaking English without an accent, unless they are native to an English-speaking country, assume they are speaking the language of their country of origin. If they are speaking with an obvious accent or are otherwise peppering their English with a few or more words from their mother tongue, assume they are speaking English. Oh, and Doktor obviously is fluent in both German and English. That's pretty much all of them that I can think of, and since you mentioned the Twin Snakes, EVA, and Big Boss, we're not getting into them.
