Freddy's disgust with Mr. Bear targeting children makes even more sense when you remember the FNAF animatronics are possessed by souls of children killed by William Afton. Seeing that happen all over again almost certainly strikes a nerve.
Part 4
In "Homer Simpson vs. Peter Griffin", Homer gets other characters to help him deliver his verses a few times, while Peter never gets any such help. This fits with the contrasting styles of their respective shows: while both shows are known for their often dark and cynical senses of humour, The Simpsons often stresses that its characters are still bonded by familial love and community loyalty despite their flaws, while Family Guy is more of a Sadist Show where the characters are generally shown as totally indifferent to anything outside of themselves.
Why is the MrBeast's battle titled "MrBeast vs. Squid Game" instead of "MrBeast vs. Seong Gihun"? Because he doesn't go up against only the latter, he also goes up against The Front Man.
Why does Olaf adopt his "Stefano" disguise when telling Loki to get help for his mental health problems? Because Loki is traditionally associated with snakes, which "Stefano" is supposedly an expert in.
Oogie Boogie's line "Decking dicey devils dealing douches dead, that's a D6" — if you take the first letter of each word, the line does indeed begin with six D's.
Part 5
Sam's hastily mentioned death at the end of "Frodo Baggins vs. Ancient Egyptians". Seeing that Frodo traversed Egypt for 13 centuries, Sam likely died during Frodo's journey and was revived to battle Anubis for him before dying again afterwards.
Why does Cthulhu regard it as a "pitiful joke" when the Kraken accuses him of copying his style? In our timeline, kraken myths predate the Cthulhu Mythos, but within his own universe, Cthulhu is a Time Abyss who was doing his thing long before there were any cephalopods to copy. So from Cthulhu's perspective, Kraken is the real copy.
Part 6
"The Rock vs. Paperboy vs. Edward Scissorhands" initially seems to broadly follow the logic of the game: The Rock reserves his most crushing disses for Edward Scissorhands, then Paperboy spends most of his verse covering The Rock. But Edward breaks the pattern, spending more time cutting into The Rock than Paperboy. Why? Because Edward was never able to fit in with other people.
It's also fitting that The Rock goes first, as rock is statistically the choice people are most likely to throw on their first game.
D.B Cooper's line: "Didn't know any Morse code so communication was dropped. No wonder your story ended with dot dot dot." On the first listen, it seems to be only a shot at Earhart's mysterious disappearance (thus ending with an ellipsis), then you realize that three dots in Morse code is the letter S, so Cooper is making a Double Entendre; Earheart couldn't finish an SOS in Morse code.
Why does Jinx bring up killing Silco in her opening lines, given it's an accident and huge tragedy in her life? Aside from her in-game lines also referencing her love of bombing and killing, she knows that it's only a matter of time before Junko brings it up instead, so she beat her to the punch.
The line ("Once I'm hitting your eyes, I'm shooting you up like Silco") is also a reference to Silco regularly injecting something into his infected left eye, a process he later entrusts to Jinx.
Star-Lord drops the Precision F-Strike in his third verse, just as the third Guardians had the MCU's first F-bomb.
At the end of the battle, Jack Sparrow trails off as he raps about Star-Lord being a distraction. He had just realised that his ship is sinking and Star-Lord distracted him as he sank his ship.
"Star-Lord vs Captain Jack Sparrow" ends with Jack Sparrow's ship nearly completely sunken, with him stuck standing on a slowly sinking mast. Not only does this mean that all of his crew and friends, including Elizabeth, probably drowned, but unless Star-Lord is gracious enough to let him onto his starship even after all the taunts at him over Gamora and his parents, Jack's doomed too.
