Jackal

Jackal (ジャッカル) is the leader to a group of outlaws. He and his men want to plunder water from the weak, arriving in the village of Bat's adoptive mother, Toyo. Jackal happens to find the elderly woman and kills her to entertain himself. His actions incurs Kenshiro's wrath and Jackal fearfully runs for his life.

The outlaw flees inside Billne Prison, a building built to house the worse of the worst before the nuclear war. Hoping to save himself he called upon his giant "younger brother", Devil Rebirth, to fight Kenshiro. When his brother is defeated, Jackal is crushed in his brother's grasp after he lights dynamite intended to be hurled at Kenshiro. Unable to escape the weight of the giant, he dies in the explosion.

Fighting Style
When fighting, Jackal uses knives hidden his bracers and a lot of dynamite. He fights dirty in order to take his enemies out as quickly as possible. However, he is smart enough to know when he is outmatched and generally avoids fights he cannot win. In the anime, he names his fighting style Nanto Bakusatsu Ken ("South Star Explosive Kill Fist").
