Humberto don Silvestre was born on Earth in 2978. He was born physically disabled, and was not expected to live a long life, until his skill at hacking computers was discovered by the authorities and his lungs were replaced with artificial ones.
He was later recruited into the military where he was badly injured, losing a hand and an eye. Cybernetically enhanced and his brain merged with an alien liquid computer system which had fallen into human hands, he became known as Silver. Thanks to his intellect and understanding of computers, he immediately integrated perfectly with the alien technology and disabled all the fail-safes designed by the scientists in order to control him.
Following an invasion of Earth in 3006, the desperate authorities used an experimental time device in a gambit to find ways of defeating the invaders. Silver was sent into the future, from where he intended not to return. Silver ended up stranded on the planet Endpoint, where he rapidly established himself as the most powerful man in Hope.
