Here’s that Superman/Dragon Ball Z Mini Fan Fic as it appeared in the comic book issue of Dragon Ball Z Part 5 Number 10 from Viz!
“This fan-fiction has been sitting around the Viz files for literally years, but since this is the last issue of DBZ, we hereby present this Superman/Dragon Ball Z crossover (possibly inspired by Dragon Ball’s “Suppaman”?) (Apparently Anime Invasion is doing their own version of this fight.) Needless to say, this is a complete work of satire and is totally unauthorized by either DC or Shuiesha. This outline will NEVER EVER appear as an actual comic, so don’t even ask.”
SUPERMAN/DRAGON BALL Z)
"The story begins in the Golden Age DC universe, in Metropolis. Lex Luthor opens a dimensional gateway which coincidentally leads to the Dragon Ball universe. In the DB universe, the opening of the gateway causes Piccolo to revert to his evil personality (why not?). Lex Luthor invited Piccolo over to the DC universe so he can defeat Superman, and Piccolo goes along in order to take over the DC universe. Meanwhile, some extradimensional villain with mysterious motives (hitherto referred to as “the new villain” -all that’s important is his name has to be a bad pun) is awakened by the gateway and sneaks through the gateway to Earth.
Piccolo arrives in Metropolis and starts causing trouble. He is challenged by Superman. They have the same power level (they both fire eye beams at one another and collide in midair, etc.) Piccolo retreats temporarily to a remote corner of Earth.
Goku arrives on Earth looking for Piccolo, along with a few of the subsidiary DB characters (thankfully, Gohan, Goten and Trunks are in school). Poccolo and the new villain meet up. Togeher they arrange for Superman and Goku to get in a fight following super-hero team up convention, during which Superman is more powerful than Goku, until Goku turns into a Super Saiyan, whereupon Goku starts to gradually defeat Superman. When they’re both caught off guard, though, and before any “who-is-stronger” questions are resolved, they’re both incinerated in a surprise blast by the new villain.
Piccolo uses his authority as the Daimo (Great Demon King) to have Superman and Goku sent to Hell instead of Heaven, where they would normally go. They both show up in the DC universe Hell with Halos around their heads, DB style. Thery are immediately jumped by demons, but easily defeated them by flicking them with one finger, etc.
Piccolo announces that he is the ruler of the new world. The heroes from the DB universe make a head-on assault against Piccolo and the new villain, but are defeated. Piccolo demonstrates his growing ki by cracking his knuckles and causing city blocks to explode. The good guys decide to stall for time until Bulma can gather the Dragon Balls to bring Goku and Superman back from the dead. All the DC characters try unsuccessfully to boast how buff Superman is (“He can squeeze coal into diamonds!”, etc) To buy time, Oolong is forced to transform into Superman (a very fat Superman) and show up in Metropolis, claiming that he’s back from the dead.
While in Hell, Goku and Superman become friends and “compare powers.” Superman demonstrates his super-speed by repairing a computer form the ground up in nanoseconds, for example (as in the Superman/Spider-Man Crossover), and when he’s done, Goku has already gone to a take-out restaurant, brought back some food and is eating lunch (“I can do that too, I just don’t bother very often.”) Goku explains the concept of ki to Superman, and starts to train him to take advantage of his full potential. Superman and Goku train by doing the sorts of tasks which people are condemned to do in Hell (helping Sisyphus push a boulder to the top of a hill, etc.)
Sensing what Superman and Goku are doing, Piccolo gets a bunch of DC villains (Doomsday, etc.) together on some pretense and kills them so they’ll go to Hell and beat up Superman and Goku there. However, thanks to his new training, Superman is able to defeat them easily. Sensing how strong the heroes are getting, the new villain puts Lex Luthor to work on a mysterious project. (The subplot begins!)
The new villain reveals his true purpose in coming to Earth: to find the Kryptonian Dragon Balls, which were sent to earth along with Superman, and which are hidden in a back corner of the trophy room in the Fortress of Solitude! Before the new villain can find all the Kryptonian Dragon Balls, Piccolo realizes what’s up and turns against him. He and Piccolo have a big fight in Metropolis, during which mass destruction is wreaked. The new villain defeats Piccolo, making him his mind controlled lackey, like in every DBZ movie."
To be continued.
