Jack Hanma

Jack Hanma's powers and abilities

Jack's strength is shown many times in the story: he killed a polar bear with his bare fists in the same way his father did, he defeating the convict Sikorsky with a punch so strong that he lifted the telephone box they were in, and later withstood Sikorsky's knuckle slash in the underground arena, taking many blows from Mohammad Alai Jr. and defeating him, cutting Ali's tongue in the process, fighting Pickle despite the strength difference and making him run away in fear by causing him to view him as the only creature that scares him, a wasp.

One of his signature technique is biting, and with jaws strong enough to bite clean through a coconut. At one point he's seen casually biting through bones like they're cookies. He decides to start a martial art, Goudou, based around biting after his tenure in Taiwan. The martial arts part comes in from the fact that biting is something everyone, even the weak like women and children can use to cause pain and defend themselves against violence with.

Despite using brute force to fight, Jack is a very tactical fighter, and is smart enough to counter and outmaneuver his opponents. For example, he made Chiharu Shiba pass out with a special type of a hold where Jack presses two fingers on the gang leader's vital points that are located in the throat (Baki defeated Gaia with a similar way; except that Baki did it with two hands, while Jack only used one hand) and also when he found the weakness of Aiki after being thrown many times and used a similar move to defeat Gouki Shibukawa. During his fight with Pickle, Jack tried to strike his middle fingers into Pickle's ears, piercing his brain. He used this as a last-ditch attack, because he was about to be knocked out and used his fighting spirit to activate this technique.
