Guo Chao was just a shut-in who coasted through life, waiting to die. Then, through his own stupidity, he went to watch a mutated typhoon and was struck dead by a bolt of red lightning from the storm, leaving behind only his soul.
That red lightning possessed a supernatural ability: it could travel between worlds.
After Guo Chao was struck dead, he became a spirit and gained a tiny fraction of the lightning's power, along with its ability to travel between worlds.
As his spirit was close to fading away, Guo Chao broke into the Dragon Ball world and seized the body of the Saiyan Raditz.
During a later battle, Guo Chao changed the plot and was driven out of the Dragon Ball world by the will of the world.
From then on, Guo Chao began his journey across worlds.
