Chaos Mario was created by an accidental split in the Mario Timeline. At the end of a typical adventure, Bowser hid powerful hallucinogens in Peach's cake mix to change the best ending. The plan backfired and the universe was restarted, but this time the drug trip became reality. Chaos Mario was created from the large amount of radiation in the new universe's creation. He gained powers of reality warping, insanity, chaos, and shapeshifting. He then began his new quest to collect the lost gameshark codes so he could find the power stars.
