Cho Hakkai

Cho Hakkai is mild, polite and level-headed. He is skilled in the art of chi manipulation and can create powerful chi blasts in battle, as well as create strong chi barriers impervious to projectile attacks. Hakkai is generally smiling but his occasional sharp gaze is symbolic of his dark, closed past.
           
Hakkai was once a human, but after killing one thousand demons in cold blooded revenge, he became a demon himself. Hakkai was gravely wounded from his battles with the demons and would have died if Gojyo hadn’t found him and taken him in. After living with Gojyo long enough for his wounds to heal, Sanzo arrived to take Hakkai to stand on trial for his sins. Hakkai was given his new name, (his old name was Gonou) and decided to live with Gojyo until their journey started.

Zhū Bājiè

Zhū Bājiè looks like a terrible monster, part human and part pig, who often gets himself and his companions into trouble by his laziness, his arrogance, his greed, his gluttony, and his propensity for lusting after pretty women. He is also jealous of Sun Wukong and often starts fights with him. In short, he is guilty of all seven sins, as well as murder, and his name translates roughly into “eight sins”.  The group regards him as a cumbersome idiot, and he is often the subject of Sun Wukong’s pranks.

In heaven, Zhū Bājiè was the field marshal in command of over 100,000 heavenly troops. After the fall of Sun Wukong, Zhū Bājiè was also banished to earth. He accidentally landed in a pig farm and was reborn as a pig demon. The only remainder of Zhū Bājiè’s heavenly powers is his weapon; a rake that weighs roughly three tons.

Comparison

            Zhū Bājiè and Cho Hakkai are perhaps the two characters that are most different from one another: Hakkai is refined and Zhū Bājiè is anything but. There are few similarities between the two, but perhaps the most obvious is their connection in heaven. Before Hakkai reincarnated to his current form, he too was a heavenly field marshal. Their names also contain similar kanji, (Chinese characters) and both begin with the kanji for eight.
