Known as 'Battery Man', the machinist claims he can act as an insulator, conductor and even a heater.
Videos on the internet show the 54-year-old powering up a lightbulb and cooking sausages by using energy stored in his body.
Slavisa, from Pozarevac, Serbia, says he discovered his amazing talent when he was a teenager.
He said: 'I was 17 years old when accidentally during work, I felt that electricity can not do anything. The rain was falling, and my colleagues made a metal fence.
The fence somehow became live, and it was then his new life began.
