Explanation:
The story takes place about half a year before the cyborgs arrive (after Trunks' warning)


A dark laboratory ...
A short, bitter-looking man with short, greasy hair. He's obviously working on a machine, the data on a nearby monitor is complicated, but the machine appears to be done. He buckles it around his arm and presses a small button on the underside. After this action, a quietly rotating drill shoots out of the front, a little longer than the man's hand.

??? : "It works perfectly ...!"

He also straps another machine around his other arm and stands up. In his extremely pale face the pure joy is evident. A joy that you only have once in a lifetime. The moment when you think you can die quietly because you have reached your goal in life.

??? : "SO! It's done! Now everyone will regret that they mocked me ... me, Adriano Estava."Behind his wire-rimmed glasses, the eyes deform into two nasty-looking slits, but his grin still persists.

Adriano: "You laughed at me. Now you will soon see the strongest fighter in the world, me."

He looks at his "masterpieces" on his arm.

Adriano: "With the help of these ... treasures I will take away the strength and almost magical techniques of the great masters of the martial arts and thus become the strongest person in the history of the universe."

Adriano reaches into a drawer and takes out a ball about the size of a golf ball and, after reading something on the digital display of the machine on his arm, presses a power source, to be precise, a few buttons. Then the thing flies off quickly.
