Hattori, Heizou

服部平蔵

Hattori Heizou is the highest-ranking officer at the Osaka Prefectural Police Headquarters and the father of high school detective Hattori Heiji. Although he presents a tough exterior, Heizou is deeply caring toward his son, family, and friends. Within the Osaka district, he maintains a close relationship with Ootaki Gorou and Tooyama Ginshirou. It is through his friendship with Tooyama Ginshirou that his son, Heiji, originally met Tooyama's daughter, Kazuha.
He maintains a very serious demeanor and appears cold, particularly when he punched his son hard enough to make Heiji fall in front of a crowd. However, it was later revealed that he merely struck Heiji to encourage more aggressive case-solving behavior and to use both Heiji and Conan as bait, though he apologized afterward. He supports his son's career as a high school detective but, as a caring father, also looks out for his son's well-being.
Heizou possesses a sharp intellect and keen observation skills. His intelligence is on par with Kudou Yuusaku, as both fathers are able to solve cases before their sons do; Heizou correctly deduced the culprit in the murder cases involving Toyotomi's castle. His deduction skills were further demonstrated in a flashback, when he solved a case simply by listening to details over the phone and providing a hint to Heiji.
