Mr Sin

The Peking homunculus, also known as the Mr. Sin, was a 51st century cyborg made in Peking for the commissioner of the Icelandic Alliance. It was made as a toy, a plaything for his children. It contained a series of magnetic fields on a printed circuit and a small computer, and a single organic component; the cerebral cortex of a pig.

It played a key role in history when the pig part took over and almost caused World War VI. After that it dissapeared. It later turned out to be in the possesion of Magnus Greel, a fugitive war criminal from the fallen Supreme Alliance, who took it back in time with him, to the 19th century, and used it to do his bidding.
