Yuujirou is a fierce and arrogant man. He shows no mercy towards anybody, as he views mercy as a "weak" trait. Yuujirou is also emotionally manipulative - this can be seen in his relationships with his son, Baki Hanma, and his ex-wife Emi Akezawa, for example. He seemingly lives only to fight and cause destruction to anything and everything he can. His whole life and mindset are dedicated to nothing but fighting and growing stronger with each person he defeats, sometimes killing them. 

Fierce, Arrogant, Prideful, Egotistical

Baki is usually a carefree, laid-back, hard-training, and sometimes aggressive teenage boy throughout most of the series. Baki strives to defeat his father, Yuujirou Hanma, who is indisputably considered the strongest man alive. However, Baki's dream is not to replace Yuujirou as the strongest man alive, but only to become strong enough to defeat him. This goal stems from a natural desire to surpass his father and avenge his mother, Emi Akezawa. Baki trains constantly and fights many people.
