The international intelligence community's first record of Bison dates
to the mid-1960's, when he was working for a Russian mercenary. Bison's early
years were marked by violence as his mercenary commando unit was hired out
to perform covert missions in Southeast Asia for the Soviet Union.
After the Vietnam War, Bison ended up in Thailand working for the nation's
military ruler. Bison's military training under the Soviet KGB made him
indispensable to the Thai ruler, allowing Bison to slowly usurp power and
eventually declare himself as the nation's dictator in 1971. However, in
1973, the populace expressed their contempt for this foreigner and his
oppressive dictatorship. A popular revolt ended Bison's rule. Bison and his
closest servants barely escaped the mobs and fled to a little-known island
off the east coast of Thailand, called Mriganka.
From the island, Bison started another bid for power, this time deeper
underground. From his mercenary days, Bison remembered his ties with the
crime network called Shadoloo, the organization through which he had illegally
purchased firearms. He renewed his association with Shadoloo and began using
its backing again. While exploring Mriganka, Bison's men discovered a cave
network that showed signs of strong radiation.
Hoping he had found a plutonium mine, Bison ordered exploration teams into
the caves. What they actually discovered was a large fragment of a meteor
that had crashed on the island untold ages ago. The survey team found the
fragment and brought a piece of it to Bison. Feeling the unnatural and
immense power of this small fragment, Bison decided to investigate the site
