most powerful technique is the "Two Blade Cut," which can cut through almost
anything.
JEFF He uses his own rough style of Karate.
He has a violent personality and likes to play mean tricks. Among the
other soldiers of the Shadow Warriors, he is some sort of leader to the
lower-ranked members.
STEVE He has the looks of a gentleman, but he's
actually a ruthless killer. He is a master of the martial arts, and he
works as an informant to the Shadow Warriors. Note: This is an unused image of
Steve from the game's rom.

He has won several street fights due to his hardened stomach, which absorbs
any attack.
CARLEM A giant whose true character remains unknown. He uses a fighting style similar to Karate. His fastest
and most chilling technique is a Middle Kick he proudly calls "the Leg of
Death." He is feared even among his companions.

advocate of dictatorship, he has taken over several dojos by force.
His personal background is a mystery and very little is known about him.
