Ivan the Terrible:
Look alive, crème de la Kremlin's arriving!
Try to serve Ivan: no surviving!
You're a land rover; I'm a land expander.
Here to hand you your first loss, Alexander!
I'll school you like Aristotle!
Smack you harder than you hit that bottle!
You're nothing but an overrated lush; I'll crush ya!
This is the second gauntlet rap battle (a battle in which one rapper faces against multiple opponents at different times), the first being Donald Trump vs Ebenezer Scrooge.
However, unlike the first gauntlet battle, the rappers in this battle are described as being on separate teams in the behind the scenes, while the characters going against Ebenezer Scrooge were all on one team.
Counting Rasputin vs Stalin and Steven Spielberg vs Alfred Hitchcock, where a multitude of rappers enter in a "battle royale" format, it is the fourth "cavalcade battle" as termed by Lloyd.
This is the seventh battle to use more than one tagged instrumental.
It was stated by Mat4yo that Peter was going to ask him to help with this battle but decided that the battle was not as hard to write as they thought.
The stance made by Frederick the Great during his title card is a reference to the iconic one-legged stance of Ian Anderson, the frontman of British rock band Jethro Tull.
During the line, "You're an asshole with an anastole," Ivan the Terrible leans in and points at Alexander the Great using his right hand in the scene with the other Russians but switches to his left hand in the next scene.
Part of Ivan's index finger is also cut off near the end of the latter scene.
During the line, "Like the eagle whose feather I would sport," "whose" is misspelled as "who's."
At 1:10, the ladle that Ivan uses to pour the poison can be partially seen through the silver cup.
At 1:43, Ivan's shadow misses the top of his hat; partially overlaps Alexander's corpse when it should fall behind it; and falls upon the stairs remaining flat, as if the stairs were a wall.
Around 2:25, when Ivan takes the seat, the shadow of the crew member who passed the seat can be briefly seen on the left as it moved.
When Ivan the Terrible says the line, "But at least I saved the rubles on the garrote wire," the garrote wire is in both of his hands; however, during the next shot, it can only be seen in his left hand.
When Catherine the Great tosses her garrote wire over her shoulder, only one hilt is ever seen falling; the other disappears once it goes over the top of the screen.
During Catherine the Great's title card, her scepter is not keyed out properly.
At some points during her verses, Meghan Tonjes' tattoo is visible on Catherine's right arm.
At 3:42, the front backup dancer's shadow overlaps onto Catherine.
During the outro, Brennan Seltzer's suggestion appears twice.
