* Most rappers have a distinct style that fits the character that the public knows them as (Mr. Rogers talks softly and gently, Mr. T yells a lot, Skrillex uses the "stutter" technique that's popular in dubstep during his vocals, etc.). Two things that stand out are Sherlock Holmes and Shakespeare's raps. They both make very good use of multis (multisyllabic rhymes-- i.e., "Deuce stain," "Bruce Wayne." The two phrases rhyme, as opposed to just one word rhyming with another), and they rhyme on the same line impressively ("No gonads, egads, it's so sad"). This could be because Sherlock Holmes is always portrayed as an amazingly quick thinker who can formulate brilliance in almost no time at all, and Shakespeare because, obviously, he's a literary genius. Their rhymes seem to stand out from the other rappers', most of whom use basic rhymes, and sometimes words that don't rhyme at all.
** Any time there's a composer involved (such as Mozart, Beethoven, etc), his music is worked into the hip-hop while he's rapping.

[[folder:Season 1]]
[[AC: Music/JohnLennon vs. Bill O'Reilly]]
* Why does Lennon hate Bill O'Reilly so much? Well Lennon was a leftwing activist. If he was alive today, he ''would'' hate O'Reilly and his ilk.

[[AC: [[Franchise/StarWars Darth Vader]] vs. UsefulNotes/AdolfHitler 1]]
* Hitler hating Darth Vader makes a lot of sense when you consider that a lot of the cast of Star Wars is Jewish (Harrison Ford, Carrie Fisher, Frank Oz, etc.).
** And Darth Vader himself was voiced by a black actor, James Earl Jones.
* Hitler says that he prefers the [[Film/{{Spaceballs}} "Rick Moranis version"]] of Darth Vader. Rick Moranis is Jewish. Either he doesn't know about Moranis's ethnicity, or [[UpToEleven he hates Vader more than he hates the Jews.]] Either way, it's hilarious.
* "Little known fact, also dope on the mic" - Not just about the rap battle thing, but referencing how Hitler motivated Germany with his renowned speeches.
* Hitler claimed he went BACK in time to mess with Vader in the prequel. The Star Wars movies were set a long time ago, in a galaxy far far away.
** Also why Vader claims he's the one who invented everything that Hitler did.
* Why does Vader claim Hitler's stormtroopers look like “someone took a piece of shit and cloned it”? Hitler's soldiers often wore black or brown, the color of, well, Skrillexcrement, while Vader's stormtroopers wear white. In terms of quality, they're also much more technologically advanced and managed to invade an entire galaxy.
* Hitler saying Vader is "not even a real person" seems to be a reference to the fact that Vader is a fictional character. However, Vader is also severely disabled, which in Hitler's view would make him not qualify as human.

[[AC: UsefulNotes/AbrahamLincoln vs. Creator/ChuckNorris]]
* Lincoln ''did'' win the Civil War "Four Score and Sixty-Five years in the past". The battle was released in 2010 and was exactly 145 years since the Civil War ended in 1865.

[[AC: Hulk Hogan vs. Kim Jong-Il]]
* Hulk Hogan's mention of owning Kim Jong-Il in a way akin to a "''WesternAnimation/SouthPark'' puppet show" might seem like [[CriticalResearchFailure an obvious mistake]] [[DumbMuscle on his part]]. However, he's probably thinking of ''Film/TeamAmericaWorldPolice'', also created by South Park creators Creator/TreyParkerAndMattStone, which also featured the so-called Glorious Leader as the primary antagonist.
** In addition, when Hogan says he'll leg drop Kim Jong-Il 'back to Beijing' it's easy to discount that as an ignorant mistake. With that said, North Korea were aided by Chinese forces during the Korean War. A mistake by Hogan, but not by the creators.

[[AC: Sarah Palin vs. Lady Gaga]]
* Why is Lady Gaga played by [=NicePeter=]? Because, as Sarah Palin alludes to, when she first debuted, many people thought she was a transvestite.

[[AC: Justin Bieber vs. Ludwig von Beethoven]]
* Beethoven's comment "Ask Bach, I got more cock than Smith & Wesson" seems inexplicable when you know that Bach died twenty years before Beethoven was born. Then you realize Beethoven is probably not talking about THE Bach (that would be Johann Sebastian) but one of J.S.'s equally musical sons, Wilhelm Friedemann and Carl Philipp Emanuel. EpicLloyd (who portrays Bach in the Beethoven vs. Justin Bieber rap) even looks a bit like C.P.E Bach.
* Beethoven's remark about Justin Bieber being a "Little White Usher" has a double meaning. The obvious meaning is what is shown in the video, where Bieber turns into a ticket usher; but it also refers to the fact that Music/{{Usher}} is the name of a musician who helped promote him.

[[AC: Albert Einstein vs. Stephen Hawking]]
* Stephen Hawking sings "I've got 12-inch rims on my chair, that's how I roll y'all". It turns out that really is how Stephen Hawking rolls.

[[AC: Genghis Khan vs. the Easter Bunny]]
* Genghis Khan vs. the Easter Bunny seems to be a battle of opposites, but they do have one theme in common: Genghis outright stated that he has an enormous amount of descendants in the present day, and [[ExplosiveBreeder what are bunnies known for?]]

[[AC: Napoleon Bonaparte vs. Napoleon Dynamite]]

[[AC: Benjamin Franklin vs. Billy Mays]]
* The only thing Mays liked about Franklin was that he founded the U.S. postal system. Since all the products he sells are mail order, he really would appreciate that.

[[AC: Gandalf vs. Dumbledore]]

[[AC: Dr. Seuss vs. Creator/WilliamShakespeare]]
* Many fans claimed that Shakespeare's first verse didn't flow well. Then there's the lyric "I hath gone iambic on that ass, ye bastard". Shakespeare's first verse is actually in iambic pentameter and once you realize that, the first verse flows perfectly with the beat.
* When the Cat in the Hat raps about Theatre/{{Macbeth}}, the blackboard behind him has the equation "1+2=SO MUCH BLOOD". [[{{Foreshadowing}} Later,]] Things 1 and 2 show up and start threatening to stick their feet up Shakespeare's ass.
* The reason why Dr. Seuss never spoke himself and let his creations rap for him? The real Dr. Seuss died from cancer in his jaw/throat area, which made it very difficult to speak in the days before he died.
* Dr. Seuss uses his book-written characters to duel Shakespeare. Shakespeare can't do that since all of his are dead.
* Shakespeare's SophisticatedAsHell style makes a lot more sense when you realize how many dirty jokes he put in his plays.

[[AC: Mr. T vs. Mr. Rogers]]
* Mr. Roger's break dancing is not just a random juxtaposition against his calmness throughout the battle. [[https://www.youtube.com/watch?v=Fw_GnjE-des Watch this and see for yourself]].

[[AC: Christopher Columbus vs. [[Franchise/StarTrek Captain Kirk]]]]
* The reason Captain Kirk hates Columbus so much is because Columbus is one of the greatest examples in history of why the PrimeDirective is necessary.
** Also why Kirk's rap derails towards the end into an attack on Queen Isabella.
** Columbus's claims he has "a neck chop for Spock, I'll put my sword through Sulu" aren't threats, they're boasts - Spock is famous for his 'Vulcan neck pinch' and Sulu is a fencer.

[[AC: Nice Peter vs. Epic Lloyd]]


[[folder:Season 2]]
* At first, Beethoven's inclusion in the season 2 trailer seems misleading, but then you remember that the Mozart Vs Skrillex battle had a similar premise to the Beethoven Vs Justin Bieber battle: Classical musician Vs modern musician.

[[AC:Darth Vader vs. Adolf Hitler 2]]
* Darth Vader raps the line "Ask Indiana Jones who the fuck I am". The Indiana Jones movies (or at least the original trilogy) take place in the 1930's, and the Nazis are recurring enemies in the movies. Hell, Indy bumped into Hitler at one point in ''[[Film/IndianaJonesAndTheLastCrusade The Last Crusade]]''. So Hitler had the chance to ask this to Indy in person! Also, obviously, an ActorAllusion as Indiana Jones was played by Creator/HarrisonFord, who had more than a few run-ins with Vader in his role as Han Solo.
* Hitler tells Vader that he appears to be in pain, right after the latter removes his iconic helmet.
** He also tells Vader to take a trip on his train. The obvious joke is a reference to the transportation of Jews to concentration camps, but it also references one of the several ways his opposition tried to assassinate him; where they bombed the train Hitler was supposed to be on.
* Hitler refers to Vader as "black". This is not only a reference to his armor's color, but also to the fact that he is voiced by Creator/JamesEarlJones.

[[AC:Master Chief vs. Leonidas]]
* Leonidas chides the Chief, saying "I've had better battles with my six-year-old son!" John (the Chief) was taken from his parents when he was six years old, and it was then that he began his forced training and transformation into the Master Chief we know today. Sure, doesn't really work its way into the dis, but it's still a nice little tidbit they slipped in.

[[AC:Wright Brothers vs. [[Franchise/SuperMarioBros Mario Brothers]]]]
* Why [[ButtMonkey Lu]][[LovableCoward igi]] is the AxCrazy LargeHam? It could be part of his [[SuperPaperMario Mr. L]] personality showing through, partially summoned by his anger towards the Wright Brothers.
** Or it could be because Luigi has [[VideoGame/LuigisMansion previously]] had to fight a dude named Orville.
** It's because the Marios are doing the PublicEnemy bit, with Luigi playing the role of Flava Flav. Notice his bling is about the size of an alarm clock.
* Why are 8-bit fists more badass than quarters? Because quarters are only 2 bits.

[[AC:Michael Jackson vs. Elvis Presley]]
* The first verse shows both singers in their primes. The second shows them as the trainwrecks they became later in life.
* During Jackson's second verse, Elvis begins eating sandwiches. He is first shown just casually taking a bite of one like it's a lunch break, but then after Jackson's line "Then you made one daughter, she came to me", he starts wolfing them down faster and looking enraged. He got his BerserkButton pressed by that line and tried to get his anger out by eating while waiting for his second verse, and in that time ended up gaining a lot more weight, hence his transition into "fat Elvis".
* When Elvis tells Michael Jackson that he has a rap for his monkey, it might refer to Bubbles... or, given Jackson's [[MemeticMolester status among many]], it might refer to [[DoubleEntendre his other monkey]].
* On the other hand, there's Elvis's line: "You lost your damn mind! that's why they cast you in ''Theatre/TheWiz''!" where Jackson plays the supposedly-brainless scarecrow.

[[AC:Cleopatra vs. Creator/MarilynMonroe]]
* Marilyn got 3 verses, the first, middle and last, while Cleopatra only got two. The third one was clearly a sort of "free throw" for Cleopatra's disgusting "Miss Carriage" joke. Evidently the announcer was ''not'' amused.
** Alternately, Marilyn got a pretty short first verse compared to Cleopatra's first verse, so she got an extra verse to make up for it.
* Cleopatra has a serious case of OohMeAccentsSlipping, half the time she sounds like she's from Queens, NY. Wait... Queens?
** It could also be since she's from ancient times and no one really knows how similar accents were back then.
* "You can't have children" is probably the most devastating insult Cleopatra could come up with. Not for emotional reasons, but because Cleopatra, as an ancient queen from a long dynasty, would have heard all her life that having children was the only way to ensure her family's continued rule. And unlike, say, [[UsefulNotes/HenryVIII Catherine of Aragon]], she ''was'' successful here, having three sons and a daughter. (Granted, one of her sons was murdered and the other two disappeared from the historical record, and this after she died and her kingdom was absorbed by Rome.)
** Likewise, this fact meant her remarks just slammed Marilyn Monroe's BerserkButton even harder - not only is [[DudeNotFunny Cleopatra crossing a line even she'd consider taboo]], but her LackOfEmpathy of the situation - i.e., [[ManipulativeBastard seeing children as tools to]] [[ItsAllAboutMe carry on one's personal legacy]] - probably indicates that Cleopatra would've been an EvilMatriarch, and would've given ParentalNeglect at best, and [[AbusiveParents would've been a nightmare at worst]]. Even though Marilyn didn't get any children, her TheReasonYouSuckSpeech to Cleopatra's TakeThat shows she would've been one HELL of a MamaBear if she did have them.

[[AC:Steve Jobs vs. Bill Gates]]
* Steve said that 'Windows bit off Apple'. Apple's logo is indeed a bitten apple.
* [[spoiler:The HAL 9000]] going up against Bill Gates makes sense when you remember that [[spoiler:HAL was a [[TakeThat potshot]] at IBM]].

[[AC:Frank Sinatra vs. Freddy Mercury]]
* The real reason Freddie Mercury got on his feet was Music/FrankSinatra implying that ''he was using his bisexuality for publicity'' ("You'll do ''anything'' to get famous!")
** It's also a roundabout [[HypocriticalHumor jab at Sinatra himself,]] who's rumored to have such a background, as well as being resentful of the rise of rock taking away some of his fame. Mercury, in contrast, was out most of his adult life, even when it was more taboo in the 80s, which makes Mercury's [[{{Pun}} rebuttal]] all the [[CrowningMomentOfAwesome stronger.]] It's somewhat implied that Sinatra really ''is'' bisexual (at least in the ERB) review, but made fun of Freddie for being [[ReallyGetsAround too promiscuous]] - as evidenced by the line "[[EveryoneIsBi Look, we all want to swing, baby]], [[EveryoneHasStandards but you took it to far!]]".
* Of course the man credited for desegregating Las Vegas practically overnight[[note]]''(by threatening to not play at venues that turned away his friend Sammy Davis)''[[/note]] "can't stand a racist!"
* Also, some of Sinatra's lyrics references some of Queen's more well known songs. Another One Bites the Dust and Bicycle Race.

[[AC:Barack Obama vs. Mitt Romney]]
* Barack Obama says that Mitt Romney has a "[[ComicBook/FantasticFour Mister Fantastic]] face." Of course he would - [[OneOfUs Obama grew up reading Marvel comics]].
* Obama vs. Romney is unique in that it was right before an election, and had the power to influence voters. The implications of a one-sided battle would have been enormous, and an indicator of ERB's political leanings. The candidates' bickering and [[spoiler:Lincoln's intervention]] do a crucial job of keeping things balanced.
** It can be said that [[spoiler:Lincoln served as an AuthorAvatar with his KirkSummation telling]] what ERB thought of both Obama and Romney at the time - that [[NiceGuy the former is extremely likeable]], but [[WindbagPolitician didn't have the guts to fulfill his promises]], and [[CorruptCorporateExecutive the later was a blatantly pro-business miser]], [[SleazyPolitician who had to resort to dirty tactics and low insults to compete against Obama]] - [[CheatersNeverProsper and was STILL coming out the loser because of it]]. Therefore, ERB can be said to have preferred Obama to Romney but only because Obama was[[spoiler:, as Honest Abe said,]] "[[DamnedByFaintPraise the shiniest of two turds]]", and if ERB had their way, [[TakeAThirdOption neither would be President]] (or at least Obama would've gotten his act together during his first term).
** Lincoln also calls out both candidates, even Romney who was a Republican like Lincoln. This is another way of keeping it politically balanced, but both parties platforms have changed significantly since Lincoln's time, with the Dems and Pubs switching places as the right and left-wing parties. Perhaps Lincoln's calling out of the Republican candidate as well as the Democratic could indicate he's unsatisfied with the direction the party has taken, as the Headscratchers page suggested.

[[AC:Doc Brown vs. Doctor Who]]
* Out of eleven Doctors to choose from, they chose [[spoiler: the Tenth and Fourth]]. These Doctors have been considered to be the most iconic and received great acclaim from fans.
** [[spoiler: Not to mention David Tennant, the actor playing the Tenth, has been on record saying that Tom Baker's run is the first he remembers- that is, the earliest Doctor he remembers is the Fourth.]]
* Doc Brown's opening CatchPhrase, "Great Scott! (Not!)" has double-meaning here -- Creator/DavidTennant, the actor who played the 10th Doctor (the one of the first verse) was Scottish.
* Doc Brown tells the Doctor to not bother trying to out-rhyme him. If you check their lines, you'll see that the majority of the Doctor's lines in either incarnation don't actually rhyme, while Doc Brown had at most one PainfulRhyme (which was the rather excusable Hot-Watts).
* At the end of the rap, the announcer proclaims, "Who won? Who's next?" as he always does. [[spoiler: Then the Doctor comes back to start the rap over and finish it early, thereby winning the battle. Who, indeed.]]

[[AC:Clint Eastwood vs. Bruce Lee]]
* Why is Clint Eastwood so racist towards Bruce Lee? It's a reference to his character in GranTorino.
* Clint Eastwood was playing dirty. Fitting, as Clint Eastwood (the actor) also played Dirty Harry.
* At first, Clint Eastwood saying "Those little dances you do don't threaten me, Bruce" seems like a derogatory remark fitting to the battle's Film/GranTorino references... until you realize that might not be as unfair a comparison as it sounds. Martial arts movies in general are in fact carefully choreographed to a point where they are often compared to dances. In fact a lot of Martial Arts stars even got their start as dancers.
** It's also doubles as a reference to Bruce Lee's status as a champion cha cha dancer.
* Clint Eastwood's line "You should spend more time matching your voice up to your lips" may actually be a very subtle case of HypocriticalHumor. Eastwood's big acting break was playing the Man With No Name in Creator/SergioLeone's "Dollars Trilogy", but one of Leone's trademarks was his tendency to cast American actors in the lead with supporting actors from wherever he could get them. On set actors would speak their native language, be it English, French, German, Italian, or any other language and the films would then dub over certain actors based on wherever that version of the film was being marketed to, so in the case of the Italian versions of those movies, Eastwood himself was dubbed over much like Bruce Lee.

[[AC:Batman vs. Sherlock Holmes]]
* Of course Batman would call Sherlock a dork. Deerstalker hats (Sherlock's signature hat) aren't supposed to be worn in common, even during Sherlock's time. Those hats are supposed to be worn by hunters or when people go to the countryside, not for everyday city wear.
* Delegating Alfred to do research seems very out of character for Bruce, who is extremely thorough and the world's greatest detective. But given the nature of his lines, he doesn't think Holmes is worth any effort at all.
* Sherlock Holmes' first verse begins with his deduction that Batman is Bruce Wayne. Almost no one in the DC Comics world knows this, yet Holmes was able to figure it out immediately. How was he able to do so? He's a master sleuth who can make connections between entities that almost no one else may have even considered.
** It does help that this Batman mentions Alfred in his first verse, making it even easier to pinpoint who's un der the cowl.
* Invoking Robin when "he's needed:" Sherlock Holmes cannot function without Watson in the stories, because Watson is the readers' surrogate. And Watson usually does very little in unraveling the mystery, because Holmes always solves it and has to explain it to Watson. Robin at least does things. And Batman also dismisses The Boy Wonder when his aid is no longer needed in the video.
** Robin's insults are much more juvenile (about screwing Holmes' girlfriend, breaking his fiddle, etc). Why? He's an impulsive teenager.

[[AC:Moses vs. Santa Claus]]
* It's pretty clear that in America, more people celebrate Christmas than they do Hanukkah. (And the few people who can spell ''that'' may not have heard of Passover, which actually does originate from the story of Moses.) Normally, that lack of popular knowledge would lead to Santa Claus winning. But since they got Snoop Dogg (who is both well-known and raps for a living), it acted as the ultimate CurbStompCushion and made Moses the popular vote.
* Why do Santa's elves love bacon so much? It's a great way to keep warm at the North Pole. [[ShapedLikeItself Also, because it's bacon.]]

[[AC:Adam vs. Eve]]
* The inclusion of someone named Steve in the Adam vs. Eve fight makes no sense until you remember one of the anti-same-sex marriage arguments was "Adam and Eve, not Adam and Steve".
* Adam gets the line "When things are good they're great and it's like I'm dreamin', until your junk starts bleeding and you turn to a demon!" This has two different meanings; the first is the obvious reference to females becoming crankier when on their period; "turn to a demon" as in turning into a demon. However, in the traditional Adam and Eve tale, Eve was the one who first accepted the forbidden fruit from Satan; hence the second, more subtle "turn to a demon" as in turning and listening to a demon or devil.

[[AC:Martin Luther King vs. Mahathma Gandhi]]
* One of Gandhi's lines is "Leave your thoughts on the door, like the real Martin Luther." Martin Luther was also the name of the 16th century founder of Protestantism (a division of Christianity) who famously nailed a list of his "95 theses" to a church door in Germany.
* Gandhi's suggestion that MLK plagiarize from him seems a bit odd at first. However, MLK did commit plagiarism in college, which Gandhi was mocking him for. Also, MLK did borrow a lot of his philosophies from things Gandhi said.
* Gandhi's comment about staying away from the hoes seems out of place, but Dr. King was known for having a number of emotional trysts. This actually caused him a lot of guilt, which means what looks like an inexplicable opportunity for an awful pun is actually a surgical strike on King's self-confidence.
** It's a double-whammy: He said it applies to protests as well. Hoes in protests? Not so much. But ''hose'' (as in fire hoses being used to disrupt protests)...
* MLK's line about having a "No-Bell Prize" must have cut Gandhi deeply. Why? Because Mahatma Gandhi [[AwardSnub never won the Nobel Peace Prize]].
* Why did Gandhi reject MLK Jr's forgiveness at the end? Because despite Gandhi being a pacifist spreading peace and love, he was borderline racist against black people. See [[http://www.huffingtonpost.com/irene-monroe/the-gandhi-none-of-us-kne_b_842941.html here and ]] [[http://www.dailytimes.com.pk/default.asp?page=story_23-3-2005_pg4_24 here]] [[http://www.gandhism.net/hisownwords.php also here]] [[http://www.theguardian.com/world/2003/oct/17/southafrica.india this one too.]] \\
[[http://www.trinicenter.com/WorldNews/ghandi5.htm This one supported the caste system and detested the "Untouchables."]] \\
[[http://books.google.com/books?id=f6vvy-J7vhcC&pg=PA54&lpg=PA54&dq=gandhi+treatment+of+untouchables&source=bl&ots=ybGwaIHo9e&sig=SfxLfE6FBLJO23dajySN0NIRkrc&hl=en&sa=X&ei=5_VmUuu8HrKy4APr4YHYAw&ved=0CHAQ6AEwCQ#v=onepage&q=gandhi%20treatment%20of%20untouchables&f=false Page 56 of this excerpt on Google Books talks about how poorly Gandhi treated the Untouchables, despite allegedly fighting for their freedom. He basically looked down on them as helpless, stupid subhumans who had to be rescued and couldn't think or act for themselves.]]
* The beat to Gandhi vs Martin Luther King Jr. ended with a gunshot. Both men were shot and killed by assassins.

[[AC:Nikola Tesla vs. Thomas Edison]]

[[AC:Babe Ruth vs. Lance Armstrong]]
* Babe Ruth rips into Lance Armstrong pretty bad for his admission of cheating, but he also makes a reference to calling his shots- there's been a strong debate over whether or not Babe Ruth was cheating by instructing pitchers to throw specific pitches. In "The Babe" he makes several enthusiastic points into the air as if he's eager to hit a home run, while [[http://www.youtube.com/watch?v=15XqYErtEfc actual footage of that very same event from the original game]] shows him merely making a hand gesture to someone- exactly where has been largely debated. Though despite the debate, no actual proof of Ruth cheating ever came to light and the general agreement was that the shot was not called in the manner of cheating, but rather he simply pointed his intent to hit a home run as a taunt to the Cubs and then hit the home run.
* When Ruth hits his home run, the pitcher was Babe Ruth as well. Ruth was primarily a pitcher when he played for the Boston Red Sox in the 1910's.
** Pitcher!Ruth then throws a tantrum. Ruth lost his cool a number of times, like when he [[http://m.mlb.com/cutfour/2015/06/23/132245176/ernie-shore-threw-quasi-perfect-game-after-babe-ruth-ejection got ejected for swinging at an umpire after one batter]]

[[AC:Skrillex vs. Wolfgang Amadeus Mozart]]
* The Skrillex side of the instrumental has segments that sound like various actual Skrillex songs, whereas the Mozart segments shift over to a more classical music sound.
* First, Mozart makes the crack, "I'm a prodigy, sonny, and I'm about to smack a bitch up!". Music/TheProdigy's most famous song is [[Music/TheFatOfTheLand "Smack My Bitch Up"]], and Skrillex's first name is Sonny. Then he says that Skrillex "reeks of dead mouse", a pun on Skrillex's friend/rival Music/Deadmau5.
* Mozart refers to Skrillex's music as "skrill-excrement". Considering Mozart's apparent documented love of feces-related humor throughout his life(of which Skrillex insults him for in the prior verse), this crack makes even more sense than being a one-off pun. He does it AGAIN in his next verse when he refers to a part of a Skrillex song as "the 68th measure of diarrhea".
* Skrillex's line "I'm a rock star, mix you with the bass and drop ya!" seems pretty straightforward; he's making a pun on "drop the bass", saying he'll mix Mozart with said bass so he can drop Mozart while he drops the bass. However, "mixing" in music terminology is when you put a song together and add effects to it so it sounds good. So Skrillex is also making a subtle pun on the term "mixing".
* "You go piano to fortississimo! (That means 'soft' to 'very, very loud' '''CAUSE I'M GUESSING THAT YOU DIDN'T KNOW!'')" For one line, if only to make fun of it, Mozart is indulging in this trick himself.

[[AC:Grigori Rasputin vs. Josef Stalin]]
* The beats start off grim, then happy, then triumphant. Why? The beats reflect Russia's history. Rasputin's and Stalin's are dark because in their times, Russia wasn't a great place to live in. Rasputin was manipulating the king and millions were starving. Then under Stalin's time, millions of people were dying in camps or getting shot, Poles were being massacred and the Germans were attacking Russia. [[spoiler:In Lenin's time, the people were starving and killing off the Tsars and starting a revolution. However, by Gorbachev's turn, where the beat gets very cheerful, Russia was slowly opening its arms to the West and things were improving. When the wall was torn down, Russia was happy for the first time in years. And if you're wondering why Putin's beat is triumphant and uplifting, it's because by the time he was in power, Russia was truly happy and no one was starving anymore.]]
* Each rapper only gets a single turn. However, if you pay attention NicePeter and EpicLloyd do alternate turns the entire time, keeping with the usual (if modified) formula.
* "Who built a superpower, but he paid the price!" Possibly, in addition to its obvious meaning, a subtle call forward to when Rasputin says "If you're the Man of Steel, I spit kryptonite!"; both are Superman references. The first by bringing up superpowers, the second with "Man of Steel".
* In his verse, Stalin yells "Shot!" four times. Exactly as many times as Rasputin was shot when assassinated.
* Why is [[spoiler:Lenin]] so angry at Rasputin and Stalin? The peasantry of Rasputin's times blamed him for [[TreacherousAdvisor using his position with the Tsarina]], making a corrupt regime worse, and before [[spoiler:Lenin's death he had specifically stated he didn't want Stalin to succeed him. After Lenin's death, Stalin went so far as to doctor photos to "prove" Lenin favored him.]]
* "If your name end with '-in', time to get out." Not just a potshot at the [[spoiler:three standing there]] or foreshadowing [[spoiler:Putin]], but a bonus jab at Boris Yelts''in'', who was mentioned in Napoleon vs. Napoleon back in Season 1.
* Why does Rasputin keep dancing during [[spoiler:Putin]]'s verse? Because [[spoiler:Putin]] mentioned "schooling every communist сука" and Rasputin isn't a communist, so it doesn't offend him.
* When [[spoiler:Putin]] says he's "a President in [his] prime", it works in two ways: when he first became president, he was in his 40s, which is relatively young for a democratically-elected leader to hit the head of state; also, he served as the prime minister of Russia, both before his rise to the presidency, and from 2008 to 2012 (while there are no hard term limits on the presidency in Russia, no president may serve more than two consecutive terms).
* "So comrade come at me" = rephrased from the phrase [[Series/JerseyShore "come at me bro"]].
* Notice how Stalin is having difficulty with ThatRussianSquatDance during the Epic Dance Battle at the end? That's because ''he's not really Russian''. He's actually from Georgia. All the others are from Russia proper: Rasputin was born in Siberia, [[spoiler:Lenin was born up the Volga from Moscow, Gorbachev was born in Stavropol at south of Moscow, and Putin was born in St. Petersburg.]]
* One could say that the episode goes from a rap battle to a... Russian Roulette.


[[folder:Season 3]]
[[AC:Darth Vader vs. Adolf Hitler 3]]
* Stephen Hawking and Abraham Lincoln being on Vader's side seems unusual considering they aren't generally thought of as villains. However, considering who his opponent is, Vader ''is'' the good guy.
* Hitler makes the IncrediblyLamePun of "A War on Two Fronts" to start off the third rematch. This actually becomes a very clever foreshadowing of the end when you realize [[spoiler:that was precisely what led to everything crashing down on him toward the end of World War II.]]
* Vader asked Hitler if Napoleon didn't tell him to pack some winter clothes when he invaded Russia. This might seem straight enough, but on a much earlier battle (Napoelon Dynamite vs. Napoleon Bonaparte), Dynamite subtly insults Bonaparte for being one of the things that has failed in Russia, which refers to Bonaparte's failed invasion to Russia. This adds three layers of brilliance:
** Layer one, a Napoleon did indeed say something about Russia, albeit implicitly.
** Layer two, that Napoleon told it to the other Napoleon, so in a sense, Napoleon never told Hitler anything about the whole stuff.
** Layer three, Napoleon Dynamite and Napoleon Bonaparte are played by Peter and Lloyd respectively, who also plays Vader and Hitler. So, in a sense, Napoleon did tell Hitler (or perhaps, Vader himself told Hitler).
* [[spoiler:Boba Fett is only on screen for a short while, barely getting to say anything, but leaving an impact before being unceremoniously killed off.]] [[Film/ReturnOfTheJedi This sounds about right.]]
** [[spoiler: Fett has four lines, followed by a scream as he's being killed...exactly the same as his dialogue in the original trilogy.]]
* Hitler screaming that "You're not going to cheat me!" after [[spoiler:shooting Boba Fett]] is a reference to how Vader was always a CombatPragmatist in the Rap Battles, first by [[TakenForGranite freezing Hitler in carbonite]], then dropping him into the Rancor pit, [[spoiler: before finally [[HalfTheManHeUsedToBe slicing him in half]] with his lightsaber]].
* The fact Vader [[spoiler: [[WhyDontYouJustShootHim only slices Hitler]]]] after [[spoiler:Boba Fett was shot]] also makes sense when, during his lyrics, he establishes the two being TrueCompanions by calling [[spoiler:Fett]] his "homeboy". Vader made [[ButtMonkey Hitler]] TheChewToy ForTheLulz (it would be ForTheEvulz if Hitler wasn't... well, [[AssholeVictim Hitler]]), but [[spoiler:[[KickTheDog killing Fett?]]]] Now ItsPersonal.

[[AC:Blackbeard vs. Al Capone]]
* Blackbeard starts by trying to distinguish pirate stereotypes from the reality. Later on, Al Capone makes a bunch of remarks about him having a bunch of crumbs stuck in his beard. This is obviously a case of ShownTheirWork in realizing that the life of an ''actual'' pirate was really quite horrific due to the terrible living conditions of any sailing ship at the time (though pirates would have it especially bad since they'd have to spend the most time at sea). Among other things, most sailors would have very bad hygiene (or in Blackbeard's case, plenty of stuff caught in his extremely thick beard) because they were unable to wash themselves due to a need to conserve their supply of drinkable water.
* Al Capone comments how he's been 'slapping bitch-ass teaches back since I was 14.' Makes more sense when you remember Blackbeard's real name was Edward '''Teach'''.

[[AC:Joan of Arc vs. Miley Cyrus]]

[[AC:Bob Ross vs. Pablo Picasso]]
* When Pablo Picasso is switching channels on the television, it shows clips of previous battles. In addition to the channel number being the number of that battle, every character who appears on it (Billy Mays, Mr. Rogers, the Fourth Doctor, and Bob Ross) are famous for being on television - Billy Mays for his commercials and everyone else for their own television shows.
** Furthermore, three of those four have been on PBS. (There was a time when ''Series/DoctorWho'', like a lot of imported British shows, ended up there).
* Bob Ross's remark about "dropping bombs like this is Guernica" makes sense when you realize that ''[[http://en.wikipedia.org/wiki/Guernica_(painting) Guernica]]'' was an actual painting by Picasso. Furthermore, the fact that Bob Ross taunts Picasso by making a joke out of it makes sense when you consider the fact that Picasso made it in response to the innocent people killed [[http://en.wikipedia.org/wiki/Bombing_of_Guernica during an actual aerial bombing]] that happened during the Spanish Civil War.

[[AC:Michael Jordan vs. Muhammad Ali]]
* Many of UsefulNotes/MuhammadAli's insults towards Michael Jordan are in the same vein of the insults he used in real life to taunt upcoming opponents. He would call them ugly, claim that they were sell-outs to white people ("Uncle Tom" is the term Ali used towards numerous fighters in his career), tell them they look more like a creature than a person, etc. In the battle, he even uses the term "whoop" (as in "I'll whoop you"), and he doesn't use it the way the current generation tends to (usually saying "I'll whoop your ass"), because that's not how he used it in real life.
* The line "You fight like the little girls who made your Nike shoes." becomes a much stronger diss after you realize it's coming from a professional boxer.
* After his conversion to Islam, calling Muhammad Ali "Cassius" (or "Clay") was [[BerserkButton an easy way to get him pissed off.]] After Jordan actually DOES refer to him as "Cassius," Ali's tone becomes more aggressive and he even threatens to "leave [Jordan] flat on [his] ass."
* Putting Muhammad Ali in a rap battle is very fitting, considering his use of rhyme schemes and spoken word poetry ended up being a major influence on rap as a genre.

[[AC:Donald Trump vs. Ebenezer Scrooge]]
* Initially, Trump's beat starts slowly, as Marley took a while to convince Scrooge he was there. After that, Scrooge's beat initially starts out chilly, the high-pitched spikes calling snowfall to mind. The beat gets moving [[spoiler:during J.P. Morgan's verse, representing the beginning of Scrooge's road to redemption. Scrooge's second verse retains the chilly atmosphere of his first, but parts of Morgan's theme are still found, meaning that although Scrooge says he wasn't affected, he was shaken slightly. The sudden change starting from Kanye West represents that, in the book, Christmas Present deals Scrooge a few blows that begin to shatter his perception of Christmas as a "humbug". It is kept in Scrooge's third verse, representing the fact that, after the encounter with Christmas Present, Scrooge is truly shaken. Yet to Come changes the beat ever so slightly, as he really drove the point in and made Scrooge understand. Scrooge finally changes his ways in the fourth verse, and the same beat is kept.]]
* Notice how [[spoiler:J.P. Morgan appears as ''soon'' as the clock in the background strikes one, and the Ghost of Christmas Yet to Come begins his verse (with "Boo!") as soon as the clock chimes a third time (you have to listen really carefully to notice it chime more than once). However, Kanye appears a second or two ''after'' the clock chimes a second time. In the original ''A Christmas Carol'', Scrooge was confronted by the first ghost the moment the bell tolled one, and the third ghost appeared "when the last chime of midnight [ceased] to vibrate"; however, the Ghost of Christmas Present (whom Kanye replaces here) had waited for Scrooge outside his door, and Ebenezer failed to approach him until appears a little bit after the clock strikes two.]]
* Why does Scrooge refer to "the Dead Donald's lecture" when Donald Trump is still alive and there was no indication of him dying in the battle? Donald Trump's role in this battle was to inform Scrooge that there are problems with his lifestyle and that he shall be visited by three ghosts who will help him change. In Literature/AChristmasCarol, this role was played by the ghost of Jacob Marley, who had died shortly before the beginning. This is even alluded to when Donald Trump displays a briefcase chained to his arms over his back, similar to how Marley is often depicted being heavily bound in chains with money boxes and various items associated with his life and warns Scrooge that a similar fate awaits him if he doesn't change.

[[AC:[[Series/TheWalkingDead Rick Grimes]] vs. [[Series/BreakingBad Walter White]]]]
* Rick keeps calling out for Carl at the start of his verses. Note that he has his hat on - in the series, Carl is known for inheriting the hat at the same time he TookALevelInBadass, so it's justified here.
* Rick pointing out how Walter gets messages written on his pancakes becomes funny if you know about Rick's mention of his wife Lori's pancakes, which were... not up to standard.
* In the BTS of ''Rick Grimes vs. Walter White'', it was revealed that the 'heroin joke' was dead. There are two reasons why, and they have to do with both shows:
** With ''Series/TheWalkingDead'': The show is about a ZombieApocalypse, and considering the 'heroin joke' was [[AnthropomorphicPersonification personified]] in the battle's BTS, it's safe to assume that it doesn't survive the apocalypse.
** With ''Series/BreakingBad'': Lloyd was the one who kept using the heroin joke in the BTS videos, essentially making him a mock drug dealer. In the rap battle, he played an ''actual'' drug dealer, selling drugs that are possibly even more deadly than heroin. Thus, Lloyd has officially played the heroin joke. Any further attempts to do so in the BTS videos would be considered moot.
* The ragged zombie in Rick's reality instantly changes to an unkempt meth addict in Walter's, without changing physical appearance. In Rick's reality it lunges at Walter to devour him. In Walter's reality, it lunges at him to get the Blue Sky meth.
** Shortly thereafter you see the zombie/addict scratching his neck. Compulsive scratching is a classic symptom of methamphetamine addiction.

[[AC:[[Franchise/DragonBall Goku]] vs. Franchise/{{Superman}}]]
* A couple of Youtube comments mentioned that Lloyd doesn't quite have the build to portray Superman. They probably never heard of George Reeves.
* Both Goku and Superman have lines about banging the other's girl - both heroes have notably averted ManOfSteelWomanOfKleenex ''and'' fathered children in at least one version of their stories.
* Superman's comment about how he's going to drop bombs on Japan with his rap seems [[ValuesDissonance off-color]] and [[SuperDickery out of character for him]]... Until you remember that in the 1940's he was used as propaganda against the Japanese Empire. [[http://www.headinjurytheater.com/images/oc%20slap%20a%20jap%20superdickery.jpg Here's a sample.]]
* Superman referring to himself as "the OG" makes more sense if you consider that Goku's origin story was deliberately based on Superman's.
* Superman being confident he'll win makes sense if you remember [[WebAnimation/DeathBattle the last time these two clashed.]]
* Superman's 'tiny genitals' line isn't just a generic diss, it refers to the fact that genitals really did come up in the original ''Manga/DragonBall'' anime, before they were [[{{Bowdlerise}} rendered nonexistent]] in ''Anime/DragonBallKai''!
* After you watch the Goku vs Superman WebAnimation/DeathBattle you can better appreciate Superman's "My level is incredible" line. His power has no known upper limit. He only applies as much as necessary to defeat the bad guy without killing him or causing collateral damage. He is literally [[StrongAsTheyNeedToBe As Strong As He Needs To Be]]. Thus, it makes sense for his PowerLevel to simply be "incredible" rather than an astronomically high number.
* When Superman says he'll "freeze (Goku's) whole measly species", it seems like just a stock example of him using his powers... until you realize Goku's entire species WAS snuffed by a villain named... Frieza.
* Superman says the line "you live in a village of idiots" which doesn't make sense, because it's never completely clear where Goku lives, but, in the same universe, [[Manga/DoctorSlump there is a very silly town of people]].
* Goku's line about "One more Superman who's never gonna walk again" is not only a reference to Christopher Reeve who broke his back and became limp, but also a reference to the ''other'' "Man of Steel", [[spoiler:Stalin]].
* Goku turning Super Saiyan right at the start of his verse makes sense considering not only Superman got the first turn and thus is the first to diss Goku, but he made ''two'' disses that are probably very personal for him (his planet and his wife).

[[AC:Stephen King vs. Edgar Allan Poe]]
* Like Dr. Seuss vs. Shakespeare, Poe's first line has the same problem of not flowing well to first time listeners. It's in trochee, which is the inverse of iambic.
* [[https://twitter.com/StephenKing/status/473571946316443648 Here]] is Stephen King's reaction to his battle against Edgar Allen Poe. He literally says Poe ''shut him down''. Because King admitted he lost, Poe gets the '''FIRST HISTORICALLY CONFIRMED WIN''' out of any Epic Rap Battle. This didn't happen again until [[https://twitter.com/D_Copperfield/status/608021111473872898 David Copperfield vs Harry Houdini]].

[[AC:Sir Isaac Newton vs. Bill Nye]]
* Nye didn't have many insults so much as backhanded (or even outright) compliments. His persona in ''Bill Nye the Science Guy'' has always been as cheerful and goofy, so in a rap battle, he naturally wouldn't know exactly what to do.
* Bill Nye's insults are based on the previous line IE "You wrote the book on Gravity but you couldn't attract no body". Gravity is the force of attraction between two bodies.
* In Newton's second verse, you can see Nye mouthing along with Newton's lyrics at one point. Nye's job on his show included having to memorize long scientific speeches from scripts; perhaps [[RealityWarper he memorized Newton's lyrics]] [[LeaningOnTheFourthWall from the episode script]] before the fight began?
* When [[spoiler:Neil [=deGrasse=] Tyson]] does his line about Newton's calculation - pointing out that the answer is "i" - his verse acquires a large amount of "i" sounds.
--> '''[[spoiler:Tyson]]''': As in '''I''' put the swag back in sc'''i'''ence wh'''i'''le '''I'''saac Newton was l'''yi'''ng and sticking daggers in L'''ei'''bniz and h'''i'''ding up ins'''i'''de his attic on some Harry Potter business!
** The equation itself is a GeniusBonus if you are aware that the answer to the integral is simply the natural log of the square root of 3, meaning Newton was literally asking Nye for the 64th root of 1. i is a valid answer, but so is 1, or -1, or -i, or any square root of i, or square root of that, or...
** It's also taken wholesale from a [[InsideJoke calculus limerick]]:
--->"The integral sec y dy[[note]](pronounced "seek y dee y")[[/note]]\\
From zero to one-sixth of pi\\
Is log to base e\\
Of the square root of three\\
Times the 64th power of i"
** Also a clever VisualPun: [[spoiler:Tyson]] enters the battle when the equation Newton wrote on the blackboard transforms into him. "The answer to your little calculation is ''I''," indeed.

[[AC:George Washington vs. William Wallace]]
* The choice of William Wallace is particularly appropriate - [[http://www.cracked.com/blog/6-forms-modern-depravity-way-older-than-your-grandpa/ the concept of the rap battle originated in Scotland.]]
* George Washington's Continentals are a strong presence in the rap battle, while Wallace's soldiers are hardly seen. Why? The Continental Army post-Valley Forge was very loyal to Washington (in many cases it was the only thing holding the army together) while Wallace was betrayed to the English by a fellow Scottish knight. [[ProperlyParanoid Wallace is right not to trust them.]]

[[AC:Artists vs. Turtles]]
* Each of the four artists is wearing the signature color of their respective turtle. Raphael's red shirt, Michelangelo's orange coat, Leonardo's blue belt and hatband, and Donatello's purple hat and sleeves.
** Not only that, but like the turtles, each artist brandishes a WeaponOfChoice when the announcer says their name: Donatello's hammer and chisel, Michelangelo's mallet, Leonardo's sketchbook, and Raphael's paintbrush and pallet.
* There's a minor case of UncannyValley with the Turtles' suits in "Renaissance Artists vs TMNT" (the mouths articulate, but not the eyes), but as a dig at the upcoming MichaelBay movie, it makes perfect sense.
* A number of people have pointed out that the Artists get more screen time than the Turtles in their episode. This makes sense - unlike most ERB characters, the Artists aren't very well-known. Everyone knows Leonardo da Vinci and many know of Michelangelo, but only someone into Renaissance art has likely even heard of Raphael or Donatello. They need the extra time to establish themselves.
** Furthermore, the turtles are used to working together, each chipping it a little. The artists, on the other hand, have never worked as a team. Note how they have to tell each other when it's their turn to rap. It's not 4 artists vs 4 turtles. It's 4 artists vs a TEAM of turtles.
* Why does Donatello look like he's dancing up on Da Vinci during his verse? It is believed that he was gay. Da Vinci was generally believed to be gay, as well. "My man Donatello" indeed, but in his case this is less certain. It's equally possible that he was bisexual. Hence why he also gets the line "I love the ladies".
* Raphael concludes his verse by saying "I should pass it up to the man in the ceiling", but he doesn't mean it in the obvious sense, since Michelangelo seems to just be on a higher floor when he begins his verse. Raphael didn't mean "on the ceiling" as in standing on the ceiling, but rather as in working on the ceiling. One of Michelangelo's most famous achievements was painting the ceiling of the Sistine Chapel.
* The first line of the TMNT's first verse is split up in a way that matches the turtles' dynamic: "The wisdom of our master taught us not to rush to violence" is said by Leo and Donnie, who are the more sensible and responsible half of the team, whereas Raph and Mikey, the more likely to break the rules, are the ones that point out that their master "ain't here, dude!". They all still chant "SPLINTER!" together as despite their differences, they all still respect their father/sensei.
* Donatello not knowing about his Renaissance counterpart may seem out of character for the smartest turtle of the group. However, the traditional trinity of the Renaissance masters is Leonardo, Raphael, and Michelangelo, so Turtle Donatello ObfuscatingStupidity is him referencing how Artist Donatello is not part of that trinity and thus would not be as well known as the other 3.
** In addition, his "Gattamelata" pun is a reference to one of Donatello's statues (in fact, the same one he's working on when the camera briefly cuts back to him), so Turtle Donatello clearly ''does'' know what his artist counterpart does, making the above even more likely.

[[folder:Season 4]]
[[AC:Ghostbusters vs. Mythbusters]]
* Winston is not present in either the title card or the commercial, he only appears when the commercial is over (In fact, he's the one who turns of the TV). This makes sense when you realize that in the movie, Winston was recruited later.
* The line referring to Literature/TheLorax during the Ghostbusters' first verse initially seems a bit confusing and out of place... until you realize that they don't literally mean the creature from the Dr. Seuss book, it's probably meant as a derogatory nickname for Walter Peck (who cited environmental concerns as his reason for wanting to shut them down). This also seems reasonable when you consider the line is delivered by Venkman, who was the one that initially refused to co-operate with Peck and thus provoked his rage.
** It might also be a burn on Jamie's mustache.
* [[spoiler:The B Team only left Mythbusters three months ago!]] Bringing them "back from the dead" doesn't make sense... unless you're even farther in the future, after a few more seasons. ERB managed to [[InvertedTrope INVERT]] WereStillRelevantDammit!

[[AC:Romeo and Juliet vs. Bonnie and Clyde]]
* Romeo's "lick my ass" taunt also refers to [=NicePeter'=]s previous role as Mozart, who wrote a tune with that title.
* How did Juliet tell [[spoiler:it was poison when she was looking at Romeo's arse]]? Well, Romeo's FamousLastWords included "apothecary, thy drugs are [[BringMyBrownPants quick]]".
* Bonnie didn't expect [[spoiler:the death of both Romeo and Juliet because she never finished reading their play]]. Them Western types weren't into no sissy book-learnin'.

[[AC:Zeus vs. Thor]]
* Why is the rap battle between Zeus and Thor portrayed using LEGO bricks? Three possibilities:
** 1: This battle is a representation of a child pitting the two gods against each other, a la ''WesternAnimation/TheLEGOMovie''.
** 2: Viewing the gods going up against each other in their true forms [[YouCannotGraspTheTrueForm would lead to death]], so LEGO bricks are used to depict the battle as an alternative.
** 3. [[RealLifeWritesThePlot There simply would not be the budget to enact the special effects neccessary to show off their power]]. Note that the shots are all more dynamic than usual, with a bunch of background characters, including three ships and a cerberus. No way they could do that in real life, with the budget they have.
* Some folks may have noticed that Lego's official Thor and Loki figures are deliberately pushed to the back in favor of original builds like the alternate Thor. That's the whole point of Lego - original creations. The guys with Zeus can all be identified as Greek gods, so it clearly works.
* One scene uses slow-mo battle shots, meant to evoke the Greek-based ''{{Film/ThreeHundred}}'', but the trailers for ''Film/AvengersAgeOfUltron'' have been spamming these, so it applies to Thor too.
* Why does Zeus outright describe Thor as having "died" while Thor only claims he'll send Zeus "deep underground"? Because in Norse Mythology, death is the fate of all things ([[MutualKill with Thor dying at Ragnarok after slaying Jormungandr]]), but in Greek mythology, the gods have CompleteImmortality, so the closest Thor could come to killing Zeus would be to directly transport him to Hades.
* Thor says at one point, "I'd spit in your face, but you'd probably like it." This is likely a reference to the Greek tradition of (mostly) dry spitting at people as a blessing and a ward against the [[http://www.greeka.com/greece-culture/traditions/ evil]] [[http://www.thinkwedding.com/WedTraditions-Greek.htm eye]].
* In Valhalla, Loki and Sif are dancing in the background, far apart. In fact, on opposite sides of The Rainbow Bridge. Why aren't they dancing together? Well, Loki and Sif despised each other. In fact, Loki cut off her hand at one point.

[[AC:Jack the Ripper vs. Hannibal Lecter]]
* It's very sensible for Jack the Ripper to use the name the papers gave him. He killed women who wouldn't give him attention, and obviously no one would be paying attention to his rap if he used his real name; they'd be too confused. Plus it's way better than anything he could've come up with himself.
* Of course Hannibal Lecter would start his first verse by "diagnosing" Jack the Ripper as a megalomaniac. He was a ''licensed psychiatrist'' before he became a cannibal and was probably carefully taking the time to observe Jack as his restraints were removed.
* Hannibal Lecter calls Jack the Ripper a "Penny Dreadful version of O.J. Simpson." This seems to be an odd person to reference, until you think about it: Lecter is one of two villains in Silence of the Lambs. Who is the other one? Well, he shares his name with the team O.J. was famous for playing on: ''The Buffalo Bills.''

[[AC:Ellen Degeneres vs. Oprah Winfrey]]
* Ellen's line "I'll bite you in the ass like a tax on a free car!" alludes to the famous incident on Oprah Winfrey's talk show when she gave a car to everybody in her studio audience, but also acknowledges the infamous backlash which came about when audience members had to pay taxes on said cars.

[[AC:Steven Spielberg vs. Alfred Hitchcock]]
* If you pay attention to the soundtrack in "Steven Spielberg vs. Alfred Hitchcock", you'll notice the fact all the verses' beats mimic the director's distinctive soundtracks: Spielberg's has a grand, John Williams-like orchestra feel. Hitchcock's has the ScareChord and a tense atmosphere, [[spoiler:Tarantino's has a jazzy, pulpy tone. Kubrick's has the operatic, bombastic feel of 2001: A Space Odyssey (complete with a few notes reminiscient of ''Also Sprach Zarathrustra'') and begins with a very science fiction vibe. Finally, Michael Bay brings a Pop, over-the-top Hip-Hop like one.]]
** Also, it sounds like they recycled [[spoiler:Michael Bay]]'s beat from the previous battle, Oprah vs. Ellen, just like [[spoiler:Michael Bay recycles movie ideas (Transformers, TMNT)]]
** In a similar vein, each director, with the possible exception of [[spoiler:Michael Bay]], performs in their rap in a setting from one of their movies. Spielberg does his verse in Film/JurassicPark, complete with a Tyrannosaurus Rex appearing in the background. Alfred Hitchcock does his verse outside of the Bates Motel from Film/{{Psycho}}. [[spoiler:Quentin Tarantino's background references Film/KillBill. Stanley Kubrick rides through the motel from ''Film/TheShining'', and begins his rap on the moon and continues it in the Star Gate, both referencing Film/TwoThousandOneASpaceOdyssey.]]
** Kubrick also isn't riding on a tricycle; it's a Steadicam mount, being one of the pioneers of the format.
* Why did none of the directors in Spielberg vs Hitchcock get a second verse to respond? You could say it's just because there were five of them, but there's another possible reason: their styles are so wildly different, they don't actually find offense in anything any of the other directors say about them, so why respond?
* [[OneSteveLimit Both Stephen King and Steven Spielberg become]] [[PungeonMaster Pungeon Masters]] by using the titles of their own works, and those of their opponent in Spielberg's case. Fittingly, Alfred Hitchcock also tries to use Spielberg's own tactics against him, starting by referring to Spielberg exposing his anus as a "Close Encounter of the Turd Kind".
** [[spoiler:Kubrick]] also does something similar, but in downplayed form by keeping the puns much more subtle. His "I'm the bomb" remark, for example, is a reference to the popularity of [[spoiler:Film/DrStrangelove (which is widely recognized as the definitive anti-Cold War film)]]. He also uses the phrase [[spoiler:"Like Clockwork"]] in reference to [[spoiler:Film/AClockworkOrange.]] He even uses the term "ultraviolent", which came from that movie and the book it was adapted from.
* While all [[spoiler:four other directors]] in Spielberg vs Hitchcock take jabs at Michael Bay, Hitchcock's doubled as a slam at Spielberg, who produced the Transformers movies.
* "I squeeze screams out of chocolate syrup" is right. That's precisely how Alfred Hitchcock created the illusion of blood for the famous shower scene in Film/{{Psycho}}.
* The silences in some of [[spoiler:Quentin Tarantino]]'s last few lines can also act as censoring out some of [[spoiler:Tarantino]]'s cuss words (for example, "[[spoiler:Quentin Tarantino]] is a [[spoiler: fucking]] genius).
* [[spoiler:Tarantino's]] line "Scripts I write ain't the cleanest" is true, especially compared to Spielberg and Hitchcock's work, but he's also the first rapper to use expletives in that battle.
* Why does Tarantino specifically mention stubbing his toe in the shower? It's well established that Tarantino has a [[FootFocus foot fetish]].
* According to the description, [[spoiler:Stanley Kubrick was played by "The Ghost of Stanley Kubrick"]] and if you pay attention to his verse, he only includes a jab at ''one'' of the three directors who have previously rapped up to this point: Steven Spielberg. Why? Because the two of them were [[spoiler:supposed to collaborate on Film/AIArtificialIntelligence and Kubrick died before it could get made. Kubrick really entered the rap battle because he wanted to get revenge on Spielberg. His responding to Tarantino calling himself a genius was just an excuse to get in.]]
* During his verse, [[spoiler:Stanley Kubrick sits down in Tarantino's chair.]] [[{{Film/Spartacus}} Given his history of taking over troubled productions]], this makes sense.
* When [[spoiler:Kubrick]] points at his eyes at the line "Like ''Clockwork'', make you all hurt" it's not merely a nod to the make-up job on [[spoiler:AClockworkOrange]] (specifically, [[spoiler:the actor of Alex having eyeliner on his right eye, which Kubrick points to]]), but also to the infamous [[spoiler:Ludovico treatment scene where Alex is forced to watch movie reels of terrible violence and war set to classical music, with his eyes forced to stay open by wires, which actually hurt the actor while filming. This, along with the inclusion of the infamous "Do that scene again" 127 times from the filming of Film/TheShining, is another nod to Kubrick being an infamous PrimaDonnaDirector. ]]
* It's debatable if [[spoiler:Kubrick]] truly took a shot at Bay, or if Bay just interpretted him as doing so. He said AI was "the worst waste of potential since the Ninja Turtle." This implies Ninja Turtles came first...meaning he was taking a shot at the original film, not Bay's version.
** It might also be about the mixed reception of the TMNT vs. Artists battle.
** "Since" in a humorous context can be used to mean "other than"; Napoleon Dynamite said Napoleon Bonaparte was "the ugliest thing that's ever failed in Russia since Boris Yeltsin".
* [[spoiler:Michael Bay's]] appearance at the end of "Spielberg vs. Hitchcock" makes even more sense when you remember that all [[spoiler:FOUR]] previous rappers (Spielberg, Hitchcock, [[spoiler:Tarantino and Kubrick]]) included a jab at [[spoiler:Michael Bay]] in their verses.
** Also note that it's only the mention of the ''Ninja Turtles'' movie that sets him off. Why, you ask? Because [[spoiler:Michael Bay]] merely serves as producer, but has been MisBlamed countless times for directing, even on this very wiki.
* [[spoiler:[[MeaningfulBackgroundEvent Note the part where Michael Bay hurls the director's chair to the left side.]]]] [[BrickJoke That's where the nuclear explosion takes place.]]
* This may not have been intentional, but there's a StealthPun in [[spoiler:Michael Bay's]] lines "Got Milk money" and "silk money." [[spoiler:Michael Bay created the "Got Milk?" ads]], and Silk is a brand that makes milk substitutes like soymilk and almond milk.
* [[spoiler:Michael Bay]] performs a crotch grab, just like another [[spoiler:Michael (Jackson)]], ''also played by Peter.''
* [[spoiler:Michael Bay's rap has quite a few detractors who say that his rapping skills are bad, but looked good due to the music, action, and special effects... which is exactly what critics say about his films, too]]. Also like his films, he's one of the most popular rappers in the battle.
--> '''[[spoiler:Michael Bay]]''': ''"I give the people what they love, the critics say I'm evil!"''
* Alfred Hitchcock's shocked reaction to [[spoiler:Michael Bay's]] final line seems a bit odd at first, until you realize the VisualPun that he invokes. Basically, [[spoiler:Michael Bay]] flipped Alfred Hitchcock Film/TheBirds.

[[AC:Lewis and Clark vs. Bill and Ted]]
* Not only will Lewis and Clark walk all over their opponents, they will then proceed to hand back "a whole stack of maps and accurate charts" on where their footprints landed. In other words, Bill and Ted could be mashed flat enough to cover an area the size of the Louisiana Purchase, and Lewis and Clark would still be able to do their jobs on the new terrain.
* Throughout the rap battle, Bill and Ted reference numerous historical figures, which leads to an amusing series of [[ContinuityNod Continuity Nods]] as the ERB versions of those characters begin to appear. However, the choices of which historical figures appear during Bill and Ted's raps (Napoleon, Abraham Lincoln, Ghenkis Khan, Ludwig Van Beethoven, and Joan of Arc) make sense when you consider that all of them were among the historical figures Bill and Ted brought to 1980's San Dimas in their film.
** Additionally, Napoleon appears on his own, while the others appear in a group shot together. This makes sense when you realize that in the film, Napoleon was accidentally brought to San Dimas early on and spent a lot of time there on his own, while the others were brought to San Dimas as a group.
* Lewis and Clark get very excited when Lewis holds up the clownfish he caught, ignoring Sacagawea's much bigger fish. They have every right to be excited - Clownfish aren't native to any American waters. They just documented yet another new species!

[[AC:David Copperfield vs. Harry Houdini]]

[[AC:The Franchise/{{Terminator}} vs. Franchise/{{Robocop}}]]
* The Terminator makes a burn about Robocop being [[GroinAttack rebuilt without his genitals]] - something that was confirmed in TheRemake. Also note that Terminators are always NakedOnArrival, and nobody around them noticing anything out of the ordinary means that Skynet went and ''made them with intact parts despite not really needing them!''[[note]]And if the reaction from the [[https://www.youtube.com/watch?v=jp5KTSaFhY0 female bar patron]] who [[FemaleGaze looks down and sees]] the Terminator's [[UnusualEuphemism crank]] in ''Film/Terminator2JudgmentDay'' is any indication, Skynet made the Terminators very [[BiggerIsBetterInBed well-hung]].[[/note]]
* The premise of this battle is "Terminator vs. a man turned robot". This battle is also created to promote ''Film/TerminatorGenisys''. Turns out, in the movie, their main adversary is indeed a man turned robot.
* The Terminator claims Robocop 3 failed Detroit worse than the automotive industry. Not only was Robocop 3 generally disappointing, and did the auto industry downsize its workforce to where Detroit's economy lies in shambles, the city has begun to resemble the dystopia shown in the Robocop movies. What caused the auto industry to lay off its workers? Robotization.

[[AC:Eastern Philosophers vs. Western Philosophers]]
* When Nietzsche spells his name, an individual copy of himself slides onscreen for each letter. All the consonants show him standing straight as a pole, but the vowels have noticeably different poses.
* Each Philosopher has a counterpart on the other side that's their primary opponent - Nietzsche and Lao Tzu, Voltaire and Confucius, and Socrates and Sun Tzu. These all make sense - Nietzsche (Works embraced by fascism) vs. Lao Tzu (Works embraced by anti-authoritarians), Voltaire (Nontraditional) vs. Confucius (Traditional), and Socrates (Soldier turned philosopher) vs. Sun Tzu (Lifetime soldier).
** Alternatively for Nietzsche, one can argue that he's still the opposite of Lao Tzu when you compare Lao Tzu's ideals on acting in harmony with the Dao, opposed to Nietzsche's belief that a man should strive to make their own morality as the "ubermencsh"
** Nietzsche also remarks about dropping a "tao of poo[h] on Lao Tsu". You might think the captions got it wrong by spelling it as ''[[Literature/WinnieThePooh pooh]]''...until you remember [[https://en.wikipedia.org/wiki/The_Tao_of_Pooh that's the title of an actual book]].
* The one who [[spoiler:turns the Western Philosophers on themselves]] is Sun Tzu, which makes sense, considering he wrote the Art of War.
* Sun Tzu is often seen either alone or actively setting himself apart from his comrades, from him jumping at the three Westerners in his first verse to backing off when he tells his companions to drop some bars, and most of his verses have just him on screen. He also sneaks off, again by himself, to stealthily taunt the Westerners when [[spoiler:they start arguing,]] and then [[spoiler:picks an argument with both Lao Tzu and Confucius.]] This all goes to highlight that Sun Tzu is the odd one out in this rap battle - He's not a brilliant ''philosopher'' like the other five, but a brilliant ''strategist'', whose literal tactics are taken abstractly.
* Socrates mentions "tak[ing] apart [Sun Tzu's] Wu with [his] [[Music/WuTangClan method...man]] ;)". Aside from "Wū" (巫) meaning a supposedly magical shaman, it can also be heard as "woo", a derogatory term for pseudoscience and "alternate" remedies and processes with no scientific backing behind them.
* Socrates mentions that he is "toxic like a hemlock sip." What does poisoning have to do with Philosophy? Well, disgraced and disliked Philosophers were prone for executions, and many earlier ones were coerced into taking their own lives with poisoned wine. Socrates himself was sentenced to death by a "hemlock sip" by Athens for his work!
* Laozi and Confucius being referred to as "Yin and Yang twins" is a reference to their respective and opposite philosophies. Confucius encouraged rule by an enlightened elite, while Daoists like Laozi encouraged 'the power of the weak', or the massed peoples. Bonus points for YinYang being a Daoist concept!
* The fact that [[spoiler:the teams fall to infighting at all! Philosophers, especially from rival schools, were prone to petty squabbles and political maneuvering. Its no wonder 5 separate schools (and a general) would turn from two teams of three into 6 angry individuals!]]
** This is also why Confucius claims he's 'way above you weak rookies' - He lived during one of those time periods and eventually his school of thought won.
** It would have been strange if the battle didn't end with [[spoiler:the members of both teams arguing - philosophers constantly criticize each other through their texts. The best example for this rap battle is Nietzsche, who has criticized both Socrates and Voltaire. They argue over important aspects of life. And that means disagreeing with other philosophers. Placing such different ideologies in two teams had to lead to infighting at some point. If Sun Tzu hadn't started it on the Western philosophers' side, it would have started on his own.]]
* When Sun Tzu delivers his final line to Socrates, he turns his head slyly to the side when referring to 'both your students here.' From his perspective, he's not looking at Socrates but at Nietzsche, who his lines were ''really'' directed at.
* Socrates getting the first turn to rap and the fact so much of the Western Philosophers' lyrics were his. It wasn't just because he was the father of Western Philosophy, its because of his status as the 'mad gadfly', which he alluded to. His career as a philosopher was (in)famous for him spurring the political leaders of Athens into acting on issues. He is acting the gadfly by starting the rap battle to begin with! "It all starts with you", indeed.
* How did Sun Tzu know he could [[spoiler:provoke Nietzsche against Socrates? Several hints are dropped in the video that Nietzsche doesn't respect Socrates, hints the Master Strategist wouldn't have missed. The biggest one is at the beginning of Team West's second verse, when Nietzsche pushes past Socrates to deliver his line rather than simply moving a few inches around him. He's also visibly the angriest rapper, which would make him easily provoked.]]
* Nietzsche takes a turn for the violent in Team West's last verse, threatening to stick his knee up Sun Tzu's chi and attesting to his ability to end motherfuckers. This seems like him just taking offense to Sun Tzu calling him a student of Socrates, but in the previous verse, Confucius said the Nazis were inspired by his work. Thing is, Nietzsche was vehemently against antisemitism, proof being [[https://en.wikiquote.org/wiki/Friedrich_Nietzsche letters he wrote to his sister]], where he lambasted her for her backwards views on the Jews. Also, that very same sister reappopriated his work for the Nazi cause. Perhaps there's more than one reason why Nietzsche went ballistic in his last moments of the battle.
* Laozi's "A bowl is most useful when it is empty" observation actually makes complete sense. When a bowl is empty, you can put something in it, but when it's full, you can't. Laozi is saying that instead of [[spoiler:"filling" the Westerners' disagreement with their own verses, the Easterners should let it play out until the opposition leaves in disgust with each other.]]
** It can also be taken as Laozi agreeing with Sun Tzu: since an empty bowl is something you can put anything into, it also stands for oportunity, just as Sun Tzu pointed out ("Their chaos is our opportunity!"). If you don't put something in it, then it's useless.
* For both the Eastern and Western philosophers, [[spoiler:the infighting that breaks out between them occurs is almost identical in how it is structured, complete with each team member making the same decisions as their counterpart on the opposing team. Nietzsche and Lao Tzu both say something that angers the person next to them. Socrates then turns on Nietzsche while Sun Tzu turns on Lao Tzu. Then Voltaire and Confucius both try to stop their team's infighting and shift the focus back towards their opponents. Neither Socrates nor Sun Tzu is willing to accept this, instead opting to insult the other partner. Voltaire and Confucius then begin to argue with the other two as well. It shows that both sides are NotSoDifferent.]]
* Lao Tzu can be seen pulling ''tai chi''-esque movies in the DancePartyEnding. ''Tai Chi'' really did originate from Taoism.
* Nietzsche's line, "Call me Übermensch cause I'm so driven!" has a very subtle StealthPun. Yes, the Übermensch as a concept describes someone with the "drive" to take control of life, but there's another "Uber" which drives a lot of people...
** Nietzsche also gets a lot more aggressive during that verse, perhaps because there's also an "Uber" that [[VideoGame/TeamFortress2 Makes you temporarily invincible]]...
* Confucius's claim that he's "way above you weak rookies" can allude to the fact that he's played in the battle by MC Jin, the only one of the six cast members to gain fame as a rapper rather than gaining it from [=YouTube=]. He's also the only one to be a first-timer to [=ERB=].

[[AC: Shaka Zulu vs. Julius Caesar]]
* Many people questioned why Shaka Zulu was chosen, of all people, to face Julius Caesar. The choice makes a ''lot'' of sense if you know the basics about both men. They have a lot in common. Militarily, their armies would have been on a similar standing - Scholars often compared them to each other - and both were known for brilliant and innovative strategies. Socially, both of them brought massive changes to the societies they lived in - Specifically, both of them transformed their respective societies into Empires. Finally, both of them were assassinated by people close to them - Caesar by the Roman Senate, Shaka by his half-brothers.
* Caesar's claim Shaka 'can't outflank the best' isn't as much of a boast as it sounds. Caesar's two most important victories - [[https://en.wikipedia.org/wiki/Battle_of_Alesia Alesia]] and [[https://en.wikipedia.org/wiki/Battle_of_Pharsalus Pharsalus]] - were won despite the enemy both outnumbering and successfully outflanking him. In the latter battle, he was actually counting on it. And since the Zulu buffalo horn formation relies on flanking...
* The end of the battle showcases the fighting formations that typically led both leaders to glory. Shaka's "Horns of the Bull" vs a Legion formation.
* Shaka Zulu describes himself as "[[Franchise/ConanTheBarbarian Conan]] of the Savannah". This isn't just a reference to his strength, bravery, and fighting skill, but also a play on the fact that the historical enemies of the Roman Empire were known as "Barbarians".

[[AC:Stan Lee vs. Jim Henson]]
* When rappers have copies of themselves in the background, it's usually one, two or three at most. [[spoiler:In Walt Disney's section,]] there's an entire army of the same guy. More indication that this is [[spoiler:The Walt Disney Company as it is now]], and not [[spoiler:Walt Disney himself]] at all.
** Similarly, [[spoiler:Disney]] is practically angrily screaming all his lines. [[spoiler:Walt]] was well-known for speaking in a calm, grandfatherly way, and rarely losing his temper. And while most rappers at least speak normally and rarely use copies, [[spoiler:Disney speaks in VoiceOfTheLegion while his army of doppelgangers rap for him most of the time.]]
* [[spoiler:Walt Disney]] says "That's my dime you're wasting". Why not "time"? [[spoiler:This being Disney the enterprise, while it does care a little about not wasting time, it cares even more about not wasting money.]]
* [[spoiler: Walt Disney's]] line about "In fact I own this whole series" sounds like a weird BadassBoast until you remember that [[spoiler: Disney]] bought out Makers Studio back in 2014. Several high-profile Youtube producers, including the Epic Rap Battles crew, work through Maker Studios to create their content.
* This one of the few rap battles with no swearing. It makes sense since it's rappers include Creator/JimHenson and [[spoiler: Creator/WaltDisney]].
* [[spoiler: Everything being painted by Walt's artists is in some way owned by Disney.]]
* When [[spoiler: Creator/WaltDisney]] turns Stan and Jim to gaze upon his "empire of joy," they both look terrified, as if they know all too well they're about to become faceless cogs in the machine. Stan's smug confidence and Jim's tranquil calm are both evaporated in this nightmare.

[[folder:Season 5]]
[[AC:J. R. R. Tolkien vs. George R. R. Martin]]
* In the battle, George R. R. Martin brags about killing off his characters, while doing so in the video to [[spoiler: Jon Snow]]. Then, near the end of his first verse, said character [[spoiler: is seen rising up off a table in the background, having apparently come back to life.]] This mirrors a scene in ''Series/GameOfThrones'' Season 6 Episode 2, which came out a mere ''twenty-six hours'' before this battle went live on Youtube. ERB took a serious gamble on this scene appearing, as this battle would have been finished long before the Season 6 premiere.
* Tolkien's comment about Martin being "a pirate who even stole [Tolkien's] R.R." could be a reference to not only the accusation of Martin plagiarizing ''Literature/TheLordOfTheRings'', but also Martin's iconic fisherman cap. It could also be a reference to how Martin's father was a longshoreman.
* Tolkien referring to Led Zeppelin is a well earned boast; the band is the Trope Codifier of HeavyMithril, and frequently referenced Tolkien's works in their songs. In short Tolkien is truthfully claiming to have inspired one of the most famous rock and roll bands of all time.
* Tolkien's line about Shire-raq refers to the fact that ''both'' modern wars in Iraq were started by [[UsefulNotes/GeorgeHWBush famous]] [[UsefulNotes/GeorgeWBush Georges]] and wound up causing significant problems for them.
* George R. R. Martin's claim that you can tell what's going to happen in ''Literature/TheLordOfTheRings'' by "page and age five" has a double meaning. The obvious meaning is that Tolkien's books are so boring even a 5-year-old can tell how they end by the fifth page. However, the history of Middle-earth is divided into distinct time periods called ages, and LOTR starts during the Third Age and ends at the beginning of the Fourth Age. Thus, Martin is saying Tolkien's world is so predictable that not only can he predict what's going to happen by the end of the book, but he can predict the ''entire'' future of Tolkien's world, ''even going into the next historical epoch.''
* Tolkien's comments on Martin's conscientious objection to the Vietnam War and the later verse "C.S. Lewis and I were just discussing/How you and Jon Snow ''both know nothing''!" could very well be taken as a jab at how Martin avoided war and yet writes war "realistically" as if he had personal experience, versus Tolkien who was in the Battle of the Somme where over a million men (including all his friends) were killed and chooses instead to write the more idealistic fantasy presented in ''Literature/TheLordOfTheRings''.
** This is subtly highlighted by how they handle their weapons. Martin uses his sword in a very inexperienced way, looking like a kid playing with a plastic toy, and when he stabs Jon Snow it's a [[GroinAttack very low blow]] rather than a clean hit. Tolkien, by contrast, handles his rifle in a professional manner, even observing proper gun safety by keeping his finger off the trigger and not pointing the rifle at anyone even by accident.

[[AC: Gordon Ramsay vs. Julia Child]]
* The Behind The Scenes video for this battle indicates that, beyond being between two famed cooking show chefs, it also represents a clash between the old way to do things (Julia Child, who only has her counter, her ingredients and her kitchen tools, does everything herself) and the new way (Gordon Ramsay, who has a whole production team behind him at the start of the video, hosts multiple shows, and even has a blue team doing the work as he sings). It could also be taken as a parallel between the New ERB and the old ERB; new ERB has constant changing backgrounds, more cinematic sections, a lot of bonus special effects, an entire crew in the background and makes frequent use of cameos and extra actors, while old ERB only had the accessories, the person singing on the screen - and little to no cameos or additional characters - and a hardly-changing background image.
* Child is cooking and prepping food throughout the rap battle. Ramsay never prepares any food. This reflects the different focuses of "The Joy Of Cooking" (Child showing you how its done) and "Hell's Kitchen" (where Ramsay isn't cooking, only passing judgments).
** And in "Kitchen Nightmares", he also criticizes the chefs, the managers and the business decisions of the restaurants he visits. More than once, he tasted food so horrible he hurried to the bathroom to throw up, as seen in a shot of the battle. Also of note, while Ramsay often cooks in "Kitchen Nightmares", it always happens off-camera.
* Ramsay holds up a Beef Wellington in the beginning, which is obviously undercooked in the middle. Undercooking a Beef Wellington is a well-known [[BerserkButton way to get on Ramsay's bad side, quickly]]. He gets noticeably more irritable after holding up the ill-prepared food.
* The jacket Ramsay offers sarcastically to Child is for the Blue Team... which is the first round in Hell's Kitchen. He won't even give her designation on the newbie team.
* Child takes all of Ramsay's criticisms and rage without yelling back at him herself, why? Because this was exactly what she went through as one of the first professional female chefs! When Julia first started out, the professional world for cooking, especially French cooking, was almost exclusively male dominated and would outright deny women from joining their kitchens.

[[AC: James Bond vs. Austin Powers]]
* Bond is the first character to use the word "cunt" in a battle since Adolf Hitler. Hitler used the word cunt because he was amoung the world's worst real-life villains, and "cunt" is seen as the worst possible insult in North America. Bond, however, uses it because it is actually fairly common in England and doesn't carry the same connotations.
* Austin Powers himself only gets one verse, and a lot of the battle instead ends up being between [[spoiler: the Daniel Craig and Sean Connery incarnations of Bond]]. This also marks the first episode in which someone raps against themself. However the choices of which Bonds are used (the original vs. the most recent) makes sense as it shows how much Bond and, by extension, the franchise, has changed over time.
* Austin Powers calling [[spoiler: Sean Connery's Bond]] "rapey" is an understatement. Possibly the least enjoyable aspect of Connery's Bond films is that they are pretty misogynistic, with the Bond girls treated as disposable sex objects or undergoing {{Chickification}}, as well as Bond making some anti-feminist statements. Case in point, [[https://www.youtube.com/watch?v=1pUXH1Bye88 Goldfinger]] actually does attempt to glorify sexual assault. Also ironic in that Austin's obsession with sex was directly mocking and exaggerating this aspect of Bond, and the women in his films were ''still'' represented better.
** Of course Craig's Bond would despise the misogyny of Connery's earlier films. One of the easiest ways to look at how the Bond franchise has changed is to examine the representations of women across different incarnations. While Connery's films are the most misogynistic of the bunch, more recent incarnations of Bond (especially Daniel Craig) have made a concerted effort to treat the Bond girls as actual human beings and to give the female characters a more active role.
** Even [[Literature/JamesBond Ian Fleming's novels]], which are quite politically incorrect, [[FairForItsDay made most Bond girls strong and independent characters]]. Honey Ryder, for example, was a brilliant naturalist and skilled sailor in [[Literature/DrNo the novel]], but [[Film/DrNo the film]] turned her into an airhead who didn't do much. And while Fleming's Bond himself was far more violent, cold and ruthless than the movie Bond, he could sometimes be ''less'' misogynistic than Connery's Bond. For example, ''Literature/{{Thunderball}}'' has Bond politely flirting with Patricia Fearing and then doing it consensually later on. The film has Bond blackmailing Fearing into having sex with him, then advancing on her and stripping her in the sauna while she protests. Even ''Literature/{{Goldfinger}}'' is less aggressive than the film in "seducing" Pussy, as it's made repeatedly clear that Pussy finds Bond very attractive. However, the film simply has Bond do it without warning.
* Craig places a particular emphasis on calling [[spoiler: Connery]] a "misogynist." Why? Aside from the above reasons, it's because in three of his four films (and the previous incarnation, Pierce Brosnan) the role of his boss, M (a role previously accepted as male) was played by Judi Dench.
* Out of all the insults [[spoiler: Connery's Bond]] could have used against Craig, he chooses to call him "Pussy." Considering that was also [[spoiler: the name of the woman he practically raped in ''Film/{{Goldfinger}}'']], it amounts to indicating that he pretty much views Craig's Bond the same way he views nearly all the women he encounters: inferior and expendable.
* Notice how [[spoiler: Connery's Bond]] immediately shrugs off Austin Powers' remark that he's "rapey," and basically denies it while stubbornly claiming to be "distinguished." That's basically what happens when you attempt to explain the misogyny of Connery's Bond films to a die-hard fan of that era.
* Austin's line about Q crafting a new plot line is more devastating if you look at ''Film/{{Spectre}}''. [[spoiler:The main villain being the (half) brother of the protagonist]] has been done before in ''[[Film/AustinPowers Goldmember]]'', making it look like Bond ripping off Austin, which is already a ripoff of Bond.

[[AC: Bruce Banner vs. Bruce Jenner]]
* The dig Jenner throws at Banner is that he can only bang his own cousin. Anyone even remotely knowledgeable in comics (especially Marvel) knows the truth couldn't be further. However, someone who doesn't know much might well just assume that She-Hulk was created as "romantic interest" the Hulk, regardless of her family ties to him. Jenner isn't the only one to make that mistake; in 2015, Film/BatmanVSupermanDawnOfJustice co-writer David S. Goyer made the same assumptions on a podcast, enraging the character's fans. The line could be a reference to that controversy.
** Alternately, it could be an allusion to ''ComicBook/OldManLogan''.
* A lot of people complained about how one-sided Jenner's battle against the Hulk was, with Jenner dishing out multiple verses worth of verbal beatdowns that Hulk had no answer to. But then you realize... of course he had no answer. He's the Hulk. His specialty is smashing things, not wordplay. If Banner had stayed calm and stayed himself he might have won; this was one case where becoming Hulk made him ''less'' capable in a battle.

[[AC: Ivan the Terrible vs Alexander the Great]]
* Both Alexander and [[spoiler:Frederick]] die in the same manner they did historically; Alexander collapsing after taking a single sip of possibly poisoned wine [[note]]Historians IRL aren't sure whether it was poisoned or not, but it is one accepted theory[[/note]], whereas [[spoiler:Frederick]] died peacefully in an armchair. Furthermore, both of them foreshadow this in their verses by making a demand of Ivan.
** [[spoiler:Pompey]] was also assassinated, but his cameo doesn't mirror it as closely, as he was stabbed rather than garroted. However, he was beheaded afterwards.
** This also explains why Ivan's attempt at dispatching [[spoiler:Catherine]] doesn't work since [[spoiler:the idea of her "[[{{BestialityIsDepraved}} dying while screwing a horse]]" was simply a myth.]]
** As stated above, it is still uncertain whether Alexander the Great was actually poisoned or not. If you look closely in the last parts of Alexander's verse, you never actually see Ivan putting anything in the wine he gives to Alexander. His claim that he poisoned Alex could simply be a case of him taking advantage of the situation to deliver a final insult.
** Technically, Ivan doesn't actually claim to be responsible for killing Alexander. His exact words are "you've been poisoned," which could be seen as him merely stating a fact (that Alexander consumed something toxic, even if Ivan didn't actually put anything into the drink). This would also parallel and foreshadow the appearance of Frederick, who also dies coincidentally at the exact moment when Ivan is going to kill him.
** The best part about all this? For an ERB battle that seems at first to toy with the old formula by having one participant kill the others, aside from the ambiguous situation with Alexander (in which Ivan may or may not be responsible), Ivan hasn't actually killed anyone, despite being the villain; yet [[spoiler:Catherine The Great did kill Pompey on-camera]]. Even better, many historical figures who showed up on ERB seemed to know how their opponent died, as it's often the point of a diss (similarly to how both Alexander and [[spoiler:Catherine]] refer to Ivan dying in the middle of a chess game). Ivan is the first one to act on this knowledge to, if not directly kill them, provoke the historical cause of death of two of his opponents.
* Ivan's second line is "Try to serve Ivan, no survivin'". Turns out he's not being hyperbolic.
* Similar to [[NotHelpingYourCase Mozart's retorts to Skrillex]], after Ivan calls him an alcoholic, Alex tells Ivan to grab him a drink and makes a vodka-themed crack.
* [[spoiler:Frederick]]'s mention of his battle tactics not being exactly straight is both a reference to [[spoiler:his preferred strategy of flanking his enemies]] and his [[spoiler:[[{{AmbiguouslyGay}} alleged homosexuality]]]]. The latter also seems like a component of the "...if I had to look at your troll face every night!" line.
** There's also reason to believe that Ivan was bisexual, so [[spoiler:Frederick]]'s line about his "troll face" may have been a preemptive rejection.
* Why is [[spoiler:Catherine]] so eager to jump into the battle that [[spoiler:she assassinates Pompey]]? [[spoiler:She]]'s out to [[spoiler:avenge Frederick, who arranged her marriage to Peter III, through which she became Empress. She doesn't want to admit it, but she owes him]].
* When [[spoiler:Catherine]] announces "checkmate", why does [[spoiler:she]] topple a fool piece rather than a king? Because Ivan ''was'' insane, and [[spoiler:she]] doesn't consider him her equal as ruler of Russia.
** Adding to this, Ivan has a dark color scheme, while [[spoiler:Catherine]] is all dressed in white and pale colors, pushing the chess theme a little further.
* [[spoiler:Catherine]] assassinating [[spoiler:Pompey]] with the garrote wire. Where did [[spoiler:she]] got it? It was the same one Ivan threw when he planned to assassinate [[spoiler:Frederick]]!
* It's pointed out a couple of times that Ivan was suffering from delusions - does it make sense now that he'd be familiar with [[Film/DropDeadFred a movie about an imaginary friend?]]
* The recurring ChessMotifs - most laymen who know the first thing about chess will be familiar with the Queen, an UrExample of GameBreaker for being able to traverse the entire board in all directions. Is it any wonder that the last man standing is [[spoiler:a woman?]]

[[AC:Donald Trump vs. Hillary Clinton]]
* At the end, Abraham Lincoln tells off both candidates, much like he did in the Barack Obama VS Mitt Romney battle, though he's much harsher towards Trump. One moment sticks out though; when Abraham says the line "Of the people, by the people, for the people", he slaps Trump twice, but looks at him only for the "Of the people" part. For the "by the people, for the people" part, he looks at Hillary menacingly, even moving a bit forward. Sure, [[WouldntHitAGirl Abraham won't hit her]], but he wants to make damn sure that Hillary remembers to have the interests of the American people in mind if she wins these elections, and not only those of people and groups close to her.
** Abe is especially harsh to Trump, which a lot of people see as a liberal bias by ERB. But it makes sense he'd be harsher to Trump than Clinton when you remember Abe's own politics - This is the man who gave us the famous 'House Divided' speech after all, and he saw exactly how bad things can get when the country is divided. He likely sees ERB!Clinton as a sleazy politician, sure, but he sees ERB!Trump as something far worse - Someone intentionally fostering disunity and division. His lines reflect this line of thought with his multiple Civil War references.
* The lines "She's your daughter!" "Well, grab her by the p***y" lines were decried as a demonization of Trump by his followers - however, while the second line is taken from the billionnaire's "locker room talk", the first line references an interview where Trump said that if his daughter [[http://www.mediaite.com/online/donald-trump-wont-stop-joking-about-banging-his-daughter/ Ivanka wasn't his daughter, he would date her]].
** Most, if not all, the lines said by Clinton and Trump in this rap battle reference lines from interviews, and can be traced back by someone who's willing to do this sort of research.
* A HarsherInHindsight interpretation of Abe's controversial 'And beat this dummy!' line isn't him telling Clinton he wants her to win, it's him criticizing Clinton's campaign. Her campaign revolved largely around sitting around waiting for Trump to self-destruct, and when that turned out to not matter she was left without an effective counter-plan. She wasn't trying to beat him, she was waiting for him to beat himself, and Abe was mocking her for this.
* Trump begins his verse by claiming to "respect all females" only to immediately insult Clinton and later brag about how he wants to shove his anus into the glass ceiling. Of course he would! Aside from showing Trump's (very flimsy) attempts to convince people he isn't a bigot, it also alludes to [[https://www.youtube.com/watch?v=MJfH9O0w1WY his inability to be consistent in anything he says]].
* Trump's final line at first seems like another attempt to bring up his racism, especially with [[CurseCutShort the part Lincoln's Eagle censored]], and it is, but it makes even [i]more[/I] sense when you realize it's also referencing two other aspects of Trump's speeches. First, it alludes to Trump's notorious tendency to draw support by making up conspiracies that have no basis in fact, but he also claims that this has happened for "the past eight years." Eight years ago was when Barrack Obama (credited as the first black president) first entered office. The line is in fact alluding to the multiple occasions when Trump has voiced his hatred of Obama's politics.

[[AC:Ash Ketchum vs. Charles Darwin]]
* Charles claims Ash's Pokémon are slaves and being forced into fighting, and that makes him sick. Now remember that Charles is the grandson of Erasmus Darwin, a dedicated abolitionist.
* This episode was released a few days before the first games of the Seventh Generation of the Pokemon series. A major trait of that generation is how certain Pokemon adapted to their environment, often becoming drastically different from the sames species as they were encountered in other regions. This is a direct reference to Charles Darwin's theory of evolution. The new region, Alola, is itself based on Hawaii and the Galapagos islands.
* Darwin has some Pokémon insults that are extremely common and even nowadays considered discredited and not taken seriously - likening Pokémon battles to slave abuse and claiming people are spending too much time on their phones playing VideoGame/PokemonGo, in particular. Darwin is an old man (who's also been kind of dead for a while), so it's rather in-character for his insults to be practically expected; if you've seen an older person criticizing Pokémon, chances are it'll be one (or both) of those points that they bring up, because they're not actually familiar with Pokémon itself. Goes along with how he calls Ash "Mighty Morphin", getting him confused with Power Rangers; mixing up shows or movies they don't care for is a common stereotypical 'old person' thing.
* The battle takes place in Alola, judging by the presence of the Alolan Exeggutor, with Darwin having just sailed on one of the islands.
* Ash having yet to catch the Ghost type. So far he had Electric[[note]][[SeriesMascot Pikachu]][[/note]], Fire[[note]]the Charizard line, two thirds of the Typhlosion line -except Typh itself-, Torkoal, the Infernape line, two-thirds of the Emboar line -except Emboar itself-, the Talonflame line[[/note]], Water[[note]]Squirtle, the Kingler line, Lapras, Totodile, Corphish, Buizel, Oshawott, Palpitoad, the Greninja line[[/note]], Grass[[note]]Bulbasaur, two-thirds of the Meganium line -except Mega itself-, the Sceptile line, the Torterra line, Snivy, the Leavanny line[[/note]], Poison[[note]]Muk, the Gliscor line[[/note]], Normal[[note]]Raticate, Tauros, Snorlax, the Ambipom line[[/note]], Bug[[note]]the Butterfree line, Beedrill, Heracross[[/note]], Flying[[note]]the Pidgeot line, Noctowl, the Swellow line, the Staraptor line, the Unfezant line, the Talonflame line, the Noivern line[[/note]], Ground[[note]]the Donphan line, the Krookodile line[[/note]], Ice[[note]]the Glalie line[[/note]], Dragon[[note]]Gible, the Noivern line, Goodra[[/note]], Dark[[note]]Scraggy, the Krookodile line[[/note]], Fighting[[note]]Primeape, Scraggy, Hawlucha[[/note]], Rock[[note]]two-thirds of the Gigalith line -except Gigalith-[[/note]]... but he does have yet in the anime to properly catch a single Ghost-type Pokémon[[note]]the Haunter from Season 1 was not properly caught. so it didn't count[[/note]].
* Darwin's line "Where actual minds do ground-breaking work" may be a pique at the Pokédex. It's unclear as both interpretations have been used in the franchise, but it's either the Pokédex itself that fills its own entries, thus not being an actual mind, or that it's filled by the children who leave on their Pokémon Training journey, explaining the often ridiculous or exaggerated descriptions. What's more, all that is needed for an entry to be filled in the Pokédex is for the machine's owner to catch a Pokémon of that species. As the rap battle mentions, Charles Darwin would spend months or even years studying certain exotic species... going as far as to try and eat them (as shown with the turtle when Darwin is announced at the beginning of the battle)!

[[AC:Wonder Woman vs. Stevie Wonder]]
* Wonder Woman's line about "Princess Diana but this lady don't die" isn't just referencing the real life Princess Diana, but it's also a reference to the fact that Wonder Woman is an immortal being.
** The line also references Princess Diana's popular nickname, Lady Di.

[[AC: Theodore Roosevelt vs. Winston Churchill]]
* Churchill's claim that it's not fair "for a British bulldog to melee with a teddy bear" is likely referencing the fact that Theodore Roosevelt abducted a cub bear after killing its parents and paraded it around. In fact this is where the teddy bear originated; a toymaker created a plush replica of "Teddy's bear" to cash in on the popularity of the bear cub.
** Another story of the Teddy Bear claims that the men Theodore was hunting with tied up a black bear with the intention of giving Theodore an easy target, since he was the only one of the group who hadn't found one that trip. Theodore decided this was unsportsmanlike and told them to let it go. If ''this'' was the version that Churchill was thinking of, then "teddy bear" could have been a [[StealthInsult stealthy way of calling Theodore a "softie",]] as well as a clever CallBack to Theodore's first line saying he preferred a challenge.
* Churchill tells Teddy "if Rushmore was a band, then you'd be the bass", implying that Teddy is overshadowed by Lincoln, Washington, and Jefferson. So it's not surprising that Teddy Roosevelt was the last of the Presidents on Rushmore to be featured in a battle. Not to mention the latter three have been portrayed by Peter, with only Teddy being portrayed by Lloyd.
* The line "I keep my rhymes pure/Like my Food and Drugs" isn't just a reference to Teddy's famous physical fitness, but the fact that he spear-headed the Pure Food and Drugs Act of 1906, which eventually lead to the establishment of the FDA and better standards for food for American consumers.

[[AC: Nice Peter vs. Epic Lloyd 2]]
* The part where Lloyd talks about Peter screwing over their friends, the backdrop is the one from ''Tesla vs. Edison''. Rather appropriate, since Edison is known to screw Tesla over. He even bragged about it in his rap battle.
* The part where the editors mess with Peter and Lloyd. Peter was given a big hand, and was called out for being a control freak, while Lloyd was given a big head, and was called out for having a huge ego.

* In Hitler vs. Vader 3, Hitler insults and mocks Vader for "bowing down to Mickey Mouse." His cracks about Star Wars being owned by Disney come off as far more sinister now that [[spoiler:we know what Disney is like in this universe...]]

* Stalin refers to himself as "the man who made Mother Russia his bitch". Fair enough, "Mother Russia" is a common nickname for the country, and he certainly ruled it with an iron fist. But more studious viewers might know that "Mother Russia" can also be used to refer to an AnthropomorphicPersonification of Russia, much like Britannia is for Britain. And considering this ''is'' [[AxCrazy Stalin]] talking, one wonders [[RapeAsDrama what horrors he might be referring to...]]
* "Anyone who sold you pierogi, shot!" Pierogis are a common dish in Poland, and well... [[http://en.wikipedia.org/wiki/Katyn_massacre]]
* Knowing about the [[https://en.wikipedia.org/wiki/Holodomor Holodomor]] puts Stalin's line about starving Rasputin until he wastes away into an even uglier light.

[[folder:Season 3]]
* Creator/EdgarAllanPoe threatening to cut Stephen King up into "itty bitty bits and sticking them in the floorboard" is appropriate enough for the macabre atmosphere of his stories. However, Poe ''did'' seem to have a thing for people committing murder in their own homes and disposing of the body without it leaving their property, given it happened several times in his stories such as ''The Tell-Tale Heart'' and ''The Black Cat''. If anything, King should just consider himself lucky that Poe isn't threatening to ''bury him alive'' like in ''The Cask of Amontillado''.

[[folder:Season 4]]
* At the end of Romeo & Juliet vs Bonnie & Clyde, the Announcer seems to have just woken up, and is very soft spoken. When he starts getting loud again? It's when he sees [[spoiler:the four bodies]]. Just like Juliet would've when she got out of her coffin to see Romeo!
** The Announcer is watching the battles just like the audience. He's as confused as Bonnie and Cylde by [[spoiler:the abrupt KillThemAll]] ending. His yelling is him getting back into character.
* During [[{{Creator/JackTheRipper}} Jack the Ripper's]] second verse, women's screams can be heard in the background. These are the sounds of the unfortunate female victims of Jack's brutal killings. Especially horrifying as this is possibly implying that he's committing these murders ''while'' delivering his verse.
** A ghost woman suddenly [[JumpScare pops up and screams]] during the announcer saying "Epic Rap Battles of History" at the end. Going by her clothing, it's a safe bet that she's the ghost of one of Jack's victims, which implies that those screams during Jack's second verse were the ghosts of other victims, which in turn implies that...his victims continue to scream for help after death.
** If you listen closely, you can hear that there are five screams in all. Jack the Ripper killed five women during his murder spree. Not only that, but the third and fourth screams actually overlap... just like how Jack's third and fourth victims were killed on the same night.
* During [[{{Franchise/Terminator}} the T-800's]] last verse, two ED-209s show up to attack Murphy. Has Skynet already invaded OCP's mainframes?
* Shaka Zulu vs. Julius Caesar implies that either the Romans or the Zulu expanded enough to come into contact with the other. Whether it was one, the other, or both, you can be sure there's a lot of bloodshed in the backstory.
* In Stan Lee vs. Jim Henson, [[spoiler: Disney's]] line "I don't sweat 'em" implies two reactions to questions about labor conditions. He is either denying that there is a problem, or saying outright that he doesn't care. Both responses are equally unscrupulous.
** The sheer fact that in the ERB universe, [[spoiler: Walt Disney]] has been corrupted so badly by his own company that he is ''no longer himself'', only the ''personification of the entire corporation as it is now.''
** As befits the [[spoiler:Walt Disney]] business model, all his lines contain zero swears, a rarity for ERB.
** As mentioned under FridgeBrilliance above, Disney owns Maker Studios, which the ERB crew uses to make their series. This adds a meta level to the scene where [[spoiler: Walt]] tells Stan and Jim to "hop on my steamboat... I'll put a smile on your face and green in your pocket... You'll be safe and insured when you're under my employ," and then forces them to gaze upon his "empire of joy". There's a reason a third rapper was cast as [[spoiler: Walt]]: He's not talking to Stan and Jim... he's talking to ''Peter and Lloyd''.
** At the end of this battle, the announcer doesn't go "Who won? Who's next?" as usual. It could be due to this being the season finale... but this could also be that [[spoiler:one of the three rappers has steamrolled the other two, asserting dominance not only over them but also the entire Epic Rap Battles series. The announcer knows it and thus doesn't ask who won. As for why the announcer sings a bit in the last two minutes of music, it may be an audio version of [[StepfordSmiler putting on a smile to hide the true feelings]].]]
