You’ve probably heard about the existence of a character named “Xicor,” infact he’s frequently referenced as belonging to Dragon Ball AF, written by Toyble.
In the story, pre Super and post DBZ, the western supreme Kai after getting absolutely pummeled by Kid Buu decides she needs a strong successor, initially she helps King Cold obtain the DNA for Frieza but after learning of his death at the hands of Goku, is more interested in the Saiyan’s DNA.
After secretly obtaining some of Goku’s DNA, she mixes it with her own to create a half Kai half Saiyan hybrid in the form of Xicor.
On earth the Supreme Kai and her son Xicor make their debut, and come across Goten, whom they nearly kill. This causes a great shockwave around the whole planet which Gohan picks up on and comes to his brother’s aid.
In an ensuing battle, Xicor demonstrates his power by destroying half the Earth in his Super Saiyan 5 form. Vegeta battles Xicor but despite his Super Saiyan 4 transformation he is no match. Super Saiyan 4 Gohan, Vegeta, and Super Saiyan Trunks battle Xicor, but despite their combined efforts they fail
However, before Xicor can act again, Kibitoshin appears and attempts to seal Xicor with the “Kai-Kai Divine Sealing Wave” into the Z-Sword, but the Western Supreme Kai intervenes and manages to prevent the sealing.
But before Xicor can destroy the sword, Gohan wields it and distracts Xicor long enough for Dende to restore Kibitoshin’s strength.
Finally Kibitoshin attempts to seal Xicor once again this time they succeed.
There’s a lot more to the story since Xicor remains the main antagonist throughout the AF story, so do give this a watch for interesting plot turns like Broly being revived, or Goku being brought back.
