Chao is one of the major villains in Dragon Ball Advanced, and is probably the most poweful, and most dangerous villain in the seires. Chao was created by Dr. Neo, who had a hand in creating Nega Montezumla. After the two Montezulmas clashed, Dr. Neo releashed his last creation, which is a cybernetic parasite which forms into Chao; Chao first takes on Montezumla, and then the rest of the Z gang as he uses his power to absorb their Ki making him stronger by the mintue. Ganon, soon is the last one standing, as he and Chao faces off in a epic, classic battle.
