"My name is X, a watcher of the Digital Worlds… and I am here to tell their story."
— From Chapter 1 of Digimon Fusion Kai before the story begins.
It's Digimon playing the role of Dragonball Z.

What's Digimon Fusion Kai?

Digimon Fusion Kai is a Fusion Fic mega-series that combines the characters & plot of Digimon and the plot & recurring themes from Dragon Ball Z. The Digimon characters are in the roles of the DBZ cast. This long-running fanfic series has been written by fanfic writer Kanius, best known for his YuYuGiDigiMoon series. It is part of Kanius Productions.

This series predates his YuYuGiDigiMoon Mega Crossover and owes its existence to this ancient Digimon/DBZ Fusion Fic. The series as a whole has been posted at least twice (technically three, counting the ongoing revision process). Once from 2001-2002, and a second run that lasted from January 2002-April 2005 with supplementary fics that lasted up to May 2006. The first versions have long been deleted from The previous second versions remain up.

In May 2010, Digimon Fusion made its return with the 'Kai' brand.

This series has been officially connected to fanfic YuYuGiDigiMoon and Digimon Accel Stream with the release of Across Dimensions. This is all thanks to a dimensional traveler named Karin Osaka a.k.a. Sailor Sedna, who has befriended a Future Trunks Expy named Dimitri Ishida.

On December 21st, 2018, Cross Generations ended and effectively concludes Digimon Fusion Kai. Unseen stories will continue to be told in Digimon Fusion Ascendancy, but Cross Generations ends the series with a 40-year timeskip to show the new generation of DigiDestined and Ascendant heroes.

On May 10, 2023, Digimon Fusion Ascendancy returns, resuming the story starting with Chapter 71:

Digimon Fusion Kai, the Movies, and Digimon Fusion Ascendancy have been crossposted on AO3:, and

The damage has been done by the work of the Dark Masters and the Digital Invaders, all under the services of a diabolical digital tyrant. When a villain named NeoDevimon arrives... well, if you watched DBZ, you should know he's Radditz. Agumon learns he was originally supposed to be aligned with these invaders (don't worry, there's no tail nonsense in this version) and well... Oh, Crap!... enter Matt and MetalGarurumon, who are in the role of Vegeta. Hell later breaks loose and an epic fight ensues. Need more?
    • Episodes 1 to 17
  • Spira Saga

After their File Island pals died in battle with the Invaders, the DigiDestined are joined by a group of human/digital warrior hybrids called the D3s/Magna Warriors/Digital Humans to land on Nam-errr... Spira (totally NOT tied to Final Fantasy X, heh). Unfortunately, as they arrive, the Digiverse's most feared tyrant, Burizalor, is there to rain on their parade and collect the Drago... Digicores. They run into the last Dark Masters, a monster named UmbraDevimon (created by Fanfic author UltraSonic007), and a five-man elite force led by Piedmon called the Nightmare Special Squad. To overcome them, the Digigang gain assistance from Spira's warriors and later Tai & VictoryGreymon.

Tai and Agumon return. The boy, Dimitri, tells them of a forthcoming Artificial threat in 11 months. 11 months pass and the Artificials attack Kyoto as Dimitri predicted.

BanchoLeomon and Artificial Jax fought an evenly paced battle, which was interrupted by Virus! Virus snuffs out Bancho and prepares to absorb said Artificial, until BlackWarGreymon intervenes and attacks the creature.

But then, one gives up in the end... and when Omega X steps out, Celesta X takes his place to fight!

After beating Celesta X, Virus takes the Digi-Vitamins and is... stopped by BlackWarGreymon, who prepares to self-destruct! It backfires as Virus blasts BWG back and unleashes the Chibi Viruses on the heroes! After BlackWarGreymon meets his end, Celesta X finally unleashes her full Ascendant power. Unleashing her Amazing Grace, Celesta demonstrates her new speed and takes the Digi-Vitamins from the monster. She then obliterates the Chibi Viruses and begins to engage Virus.

Regressed back to his imperfect form, Virus is no longer a threat, but he pumps himself up into a balloon out of desperation. Omega X makes the save and teleports but DOES NOT DIE!

But Da'ath makes their return with an expanded organization, prompting the characters to team up in order to save their universe.

The series provides examples of:

  • Adaptational Personality Change: Since this is a Digimon story adapting Dragon Ball, some personalities are tweaked and altered to match the DB characters that the Digimon characters are portraying. The most conspicuous example is Yamato 'Matt' Ishida, who thanks to Burizalor's manipulations has his inner dark persona, named just 'Yamato', doubles as a Vegeta personality all while this dark 'Yamato' hijacks Matt's mind and body spontaneously or when seduced into a fight with a powerful opponent.
