Gennai Hiraga

Gennai Hiraga was the original figure who destroyed the White House and appears multiple times throughout the series. He unleashes a mysterious power in the form of green lightning bolts which is used in the series to cut the entire electricity supply of New York City, disable aircraft and destroy buildings in Washington DC. In the final episode at the I-Jin fortress, Yomiko and Gennai engage in a swordfight, using a lightsabre-type weapon and a paper sword respectively. He dies when Yomiko uses a $100 bill to rupture a liquid nitrogen coolant line, whereupon he is frozen solid and shattered.
