A universe located on Fantendo consisting of several fanon shows that primarily revolve around groups of friends in various places and times, such as space, in wartime, and even in an anime style. The universe features several common elements and archetypes. Starting with The Jam, it quickly expanded.
- The Jam: Five friends go on adventures together.
- Jamverse Anthology: A short-lived anthology series meant to expand the universe.
- Fantendo the Anime: An anime version. To the people of the Jam, this world is but a story.
- Jamming Again: A reboot.
- High Above Them: Five friends go on adventures together...IN SPAAAACE!!!
- War Jammin: Friends go on adventures together during war time.
- Crisis on Infinite Jams: Crossover movie.
This universe provides examples of:
- A Day in the Limelight: Several episodes in The Jam have episodes centered around other characters, such as We Be Pimpin (which focuses on Locky), You're Going To Far, Kid (which focuses on Fandro) and etc. It's spiritual successor High Above Them also features this, with episodes like Crescendo(focusing on Dark) and The Ace Job(focusing on Ethan).
- Alternate Universe: Jamming Again.
- Cloudcuckoolander: Ella Sketch and, to a lesser extent Sketch. Cameron Sketch averts this.
- Bat Family Crossover: The ''High Above Them" episode Jamming.
- During the War: Almost all of "War Jammin'" takes place during the "War of the Ages".
- Early-Bird Cameo: Locky makes one in the first episode of The Jam during the stinger of that episode before his actual introduction in We Be Pimpin. Likewise, the Season 2 main villian Artemis makes an appearance during a flashback of said episode but she is only introduced during Season 2.
- The Stinger: The first episode of The Jam (Not-So-Random Access Memories) features one at the end of the episode, after everyone left the coffee, Locky enters in wondering where did went.
- Shout-Out: The first episode's title in The Jam is a reference to one of the episodes in Fantendo the Animated Series.
- Spiritual Successor: The Jam can be techincally called one to Fantendo the Animated Series as it features some of the original writers working on a concept similar to F Ta S. The Jam itself got two spiritual succesors, Jamming Again and High Above Them.
- Recycled In Space: Jamming Again and High Above Them.
- Poorly Disguised Pilot: Averted. One of the episodes of The Jam called Made In Japan, in which the characters seems themselves in an alternate dimension in which they are in a war. This concept was later used on one of the spiritual succesors, War Jammin, although that was never planned during the planning of The Jam and this connection between the two might just be a coincidence.
