Trivia

  • The episode is a tribute to Cartoon Network.
  • The idea of Crossover Nexus came from the Point Prep Arc, a location of OK K.O.! Let's Be Heroes.
  • The crossover was meant to be 22 minutes, but Cartoon Network decided to cut it down to 11 minutes so the crossover could take place in CN City.
  • The crossover was announced during San Diego Comic Con 2018.
  • New theme songs of Cartoon Cartoons, CN City, and Fridays were played.
    • The Fridays theme song was a slow depression music and was played during the scene where K.O., Garnet, and Ben are inside the Screwy Ain't It building and discover lots of Cartoon Network heroes that were summoned and defeated by Strike.
    • The Cartoon Cartoons one was a remixed music and was played during the scene where Ben transforms into multiple Cartoon Network characters to defeat Strike.
    • The CN City one was an opera music and was used during the scene where CN City is being restored by Strike's pen.
  • The crossover officially marks the very first (and currently only) time that Moxy (from The Moxy Show) was featured in an official Cartoon Network product since Cartoon Network's 10 years in 60 seconds tribute video in 2002.
  • Periwinkle (from the lost Cartoon Network anthology series, Sunday Pants) made a cameo in this episode, which also marks the first and currently only time that Sunday Pants was featured in official Cartoon Network media.
  • Two characters came from Two Cartoon Network originals that weren't created in the US: Jorel's Brother (from Jorel's Brother) and Black Hat (Villainous).
    • Jorel's brother's cameo was most likely due to Ian Jones Quartey's visit to Brazil in 2017, where he was at a Comic Con experience to do a live drawing with Juliano Enrico, the creator of Jorel's Brother.
    • Black Hat with the heroes was very strange because he is a villain even though he's the protagonist of Villainous. However, according to an episode of "Videos of Guidance for villains: Q & A Blackhat Organization responds", stone Black Hat was actually a clone from the short, The Perception of Evil.
  • The Cartoon Network originals that didn't appeared in the crossover were:
    • Class of 3000
    • The Secret Saturdays
    • What A Cartoon!
    • Space Ghost: Coast to Coast (due to the series being from Adult Swim since 2001)
    • Mixels (as it was co-produced by LEGO)
    • Star Wars: Clone Wars (due to Disney being the current owner of the Star Wars franchise)
    • Transformers Animated (due to Hasbro owning all Transformers media)
    • Ben 10 (original series), Ben 10: Alien Force, Ben 10: Ultimate Alien, and Ben 10: Omniverse.
    • Big Bag
    • Live action shows: Dude, What Would Happen, Destroy Build Destroy, etc.
