So, Crossbones plans on fighting the might KGBeast uh? Well lets look at what this lil hulk can do.
Who is the KGBeast?
Trained by Hammer, a secret KGB group the KGBeast is a master of over several different fighting styles has enhanced strength. He is also a master of every single weapon on the planet. So not only does he have his cybernetic arm, he can also use weapons he may get from Crossbones if he drops or loses one.
Skill wise, the Beast is up there. Facing people like Batman, Robin, and Huntress. Both of our combatants have several different martial arts mastered, so this is going to be tough. We have to use feats!
Vs. Batman 1
During his first encounter with the Bat, Beast completely shocked Bruce. Saying how skilled and fast he was, fighting like an animal. He then was able to evade Batman and continue with his mission.
He was also able to defeat Huntress.
While it is off panel it should count for something I believe.
Those are just to give ideas of his skill.
I'll have to post later tonight I must go. Until then my friend.
