Mr. Chen is a rich man who owns a hotel. He appears to be a very strict father to Jimi Chen, which would explain why Jimi feels the need to act out as the school bully, and wanting to be known by everyone. Mr. Chen calls his son by his Chinese name - Jin Gau, which can be heard in the Series 1 episode Family Ties. He is very angry with Jimi when he learns that he ruined the art display at the school, and makes his son buy Katrina a new jacket since her mother's old one was destroyed.
Due to Mr. Chen's strict and distant nature, it makes Jimi feel unwelcomed, alone, and jealous of others. Jimi expresses his feelings to Rhydian about being a disappointment in his father's eyes.
