here’s the list of universes that my mega-crossover uses that has Fanon Discontinuity(note: at least some of the universes used by Ani-Toonspiracy project are too good to even get this treatment):

• Pokemon anime: stops following Official canon after Rivalry Revival episode where after this episode, Tracey accompanies Ash and company to Johto(and later regions) instead of becoming Professor Oak’s assistant
• Heroes tv show: goes canon AU from event where Hiro and Ando offered to join Arthur’s team only to having Hiro refuses to join it
• Kingdom Hearts: Dream Drop Distance-onward have their continuity ignored(even when this uses some elements from KH3, notably convoluted plots from Birth by Sleep)
• Digimon adventure: stop following official canon past Our War Game movie
• Crysis: Crysis 2-3 and Comics never happened
• Classic Doom: Doom 2016 and Eternal never happens, if either are classic Doom's sequels
• My Little Pony Friendship is Magic: anywhere past Canterlot Wedding
• Prototype: Prototype 2 never happened
• Teen Titans 2003: Teen Titans Go(tie-in comics, not to be confused with 2013-now Cartoons of same name) comics that published after Teen Titans’ cancellation mostly never happens
• First Encounter Assault Recon, especially it’s monolith timeline: F3AR retconned away from Hiro Nakamura stopping Genevieve Aristide from shutting down Telesthetic Amplifier. even when this happens, F3AR still happens no matter how hard it got retconned(for the same reason everything we’re forgotten stays in our brains)
• Avatar the Last Airbender/The Legend of Korra: Ending(when both Korra and Asami are lesbians) are retconned likely from the part where Korra got poisoned never happened here
• C&C Red Alert series: Renegade 2 was used as Yuri Revenge’s sequel instead of Red Alert iOS(to further explains away Tiberian Universe as temporal paradox that Allied forces made in last ditch effort to save the world from Psychic Dominator Disaster)
• The World Ends With You: Neo-TWEWY never happened
• and so on
