One of the eight generals, he uses the weapon household's vessel "Balalark Sei." His loyalty towards Sinbad is so high that he'll approach anyone who insults him with murderous intent. When Sinbad does things as he pleases, Ja'far worries endlessly and sometimes even feels faint.

Ja'far usually only wears official clothing as he only has one set of normal clothing he received from Sinbad when he was 14 years old.

His name is based on the "Harun al-Rashid's" Persian vizier "Ja'far ibn Yahya" also known as "Ja'far al-Barmaki" which is one of the real people (not a fictional character) in "One Thousand and One Nights" stories. He appears in many stories in the "One Thousand and One Nights" series.
