Virtual ON Cybertroopers
He's the very large guy that you fight that's unmentioned in the manual. To play as him, at the title screen, press and hold down. While holding down, press L & R together. There should be a sound to tell ya that ya did it. He's not seen on the character screen, he's to the right of Raiden. When you play him, you'll find out he's based on Raiden, but alot stronger and bigger.
At the title screen (when the the words "press start" are flashing) hold Up and press L+R simultaneously. The cheat makes both Raiden and Temjin have new color schemes.
