KGBeast

The KGBeast was first seen when he was killing certain people in Gotham, the last of whom was supposed to be the President of the United States--Ronald Reagan, at the time--during his visit to the city. During an early encounter between KGBeast and Batman, KGBeast pounded Batman and ran only because he thought Batman had back-up. Batman realized that that error saved his life, and chased KGBeast across the rooftops, knowing that he had to be more careful.

During a later encounter, Batman caught KGBeast's wrist in a loop of the Batrope. He figured he'd just hang there until somebody showed up to arrest KGBeast. However, rather than be captured, KGBeast cut off his own hand with an ax.

KGBeast's physique is enhanced due to extreme conditioning by the KGB. He also is belived to have cybernetic implants in his body.
