In the Part 4 finale, guest starring Keyblade, the Villain Protagonists of Money Heist and The Wolf of Wall Street, The Professor and Jordan Belfort, respectively, faces off against each other in a money-themed rap battle.
This rap battle contains examples of:
- Capitalism Is Bad: The Professor sums up Jordan's Protagonist Journey to Villain as "the before and after picture of capitalism".
- Not So Similar: While both rappers have similarities, mainly the fact that both are law-breakers, the Professor makes it clear in his second verse that they are not the same, starting from the fact that the Professor isn't blinded by greed unlike Jordan.
- Prison Rape: Referenced when the Professor says that once Belfort gets arrested, he will leave Belfort and his prison-mates with the soap.
- Sampling: A remix of "Bella Ciao" (known for its use in Money Heist) is played in the intro and outro.
- Special Thanks: As a Part finale, the ending credits has a long list of Special Thanks, thanking nearly everyone who have ever been involved with the series, and lastly thanking the series' inspiration Epic Rap Battles of History.
