    Heiji Hattori 

Heiji Hattori/ Harley Hartwell

Voiced by Ryo Horikawa (JP)

The high-school detective of Osaka who serves as Shinichi's main rival. He eventually learns of Shinichi becoming Edogawa Conan and decides to keep it a secret, but is kept in the loop on the latest information regarding the Black Organization.

He and Shinichi become close friends as the series moves along, and are always seen together when they're solving cases...or talking about girls.

Mandatory naming note: Hattori came from Inspector Hattori of Tantei Monogatari who worked with Kudo Shunsaku. Heiji came from Zenigata Heiji, a fictional police officer in the Edo era.

  • Accidental Pervert: He told Kazuha to take her clothes off. She was shocked for a moment, while Heiji was attempting to undo her clothes, and slapped him. The reason was that she was knocked out earlier with a stun-gun and he was looking for a small burn mark.
  • Alliterative Name
  • Always Second Best: When Heiji and Shinichi work together, they're each other's equal and will often arrive at the same conclusions. But when they compete with each other or their deductions differ, Shinichi usually wins.
  • Amateur Sleuth
  • Ambiguous Disorder: Heiji is really thick about other people's feelings, bad at picking up social cues, and extremely awkward a lot of the time. He can't lie without stuttering and giggling like an idiot, and he latches onto ideas or interests and does not let them go. For example, when he first became friends with Conan, he talked about Shinichi SO incessantly that his childhood friend believes him to have a girlfriend in Tokyo with the last name Kudo. He's also extremely adept at remembering little details and noticing anything out of the ordinary, no matter how minor.
  • Ambiguously Brown: He's clearly Japanese, and he inherited his dark skin from his grandfather, but we don't know ultimately what that comes from.
  • Badass Biker: Shown in full extent in the non-canonical third movie.
  • Belligerent Sexual Tension: With Kazuha.
  • Berserk Button: Heiji has shown his extreme dislike of men flirting with Kazuha, but if anyone so much as threatens her, or makes him think she's being threatened, Heiji will kick your ass. In fact, this is what led to Heiji's confession.
    "Whatcha doin' to MY Kazuha!!?"
  • Big Ol' Eyebrows
  • Blade Run
  • Catch Phrase: "Ahou," Kansai Regional Accent version of baka.
  • Chick Magnet: Shown in full during the Nanami Swordsman and Toyotomi's Castle case, when a group of girls were excited meeting Heiji. It turned out Heiji asked a friend to pretend to be him for a moment so he could talk to Conan.
  • Childhood Friend Romance: With Kazuha.
  • Common Eye Colors
  • Crazy Jealous Guy: Like how Shinichi acts towards Ran, Heiji really doesn't like it when a guy looks like he has an interest in Kazuha. When this happens, Heiji is unable to concentrate on the case at hand. His jealousy is even worse than Kazuha's jealous moments.
    • He doesn't even like it when she talks about another guy i.e. Kazuha calling Shinichi Kudo "really smart".
  • Determinator: Not only did he refuse to let go of Kazuha while they were hanging off the edge of a cliff after she'd stabbed him in the hand to try and make him let go of her , he somehow managed to pull themselves back up off screen.
  • Ditzy Genius: While a bit controversial, Heiji is sometimes thought as such. He's a brilliant detective, but can't for the life of him remember to call Shinichi 'Conan' when they're in public. He also has a bit of a Hair-Trigger Temper, particularly when talking to his childhood friend Kazuha.
    • So much so that one fanfiction diagnosed Heiji with Asperger's Syndrome in a fictionalized psych profile.
      • Which is unfortunate, as very few of the traits match the Syndrome, and this is more of a case of Art Major Psychology.
  • Hair-Trigger Temper: Matches perfectly with his hot blooded nature, Heiji has a tendency to snap at people, even when they haven't done anything so wrong i.e. he yells at Kazuha for suggesting he take a break from a case and eat.
  • Heterosexual Life-Partners: Becomes this with Shinichi/Conan over time.
  • Hot-Blooded: Frequently called out on this by anyone he meets.
  • The Idiot from Osaka: Prankster sub-type.
  • Improvised Weapon: He often improvised whatever he has for a sword.
  • Jerk with a Heart of Gold: Has a quick temper, a high-and-mighty attitude, the sensitivity training of a snapping turtle, and can be disrespectful to his parents, older adults, and even his friends. However, there's no denying his strong love for protecting those closest to him, and his strong sense of justice is on par with Shinichi/Conan.
  • Kansai Dialect
  • Kendo Team Captain: And has apparently done pretty well against the famously tough members of the Osaka PD.
  • Master Swordsman: Of the kendo variety. See Kendo Team Captain for more details.
  • Nice Hat: His trademark "Sax" hat. Normally his hat is placed backwards, but whenever he feels a challenge he'll turn all the way to the front, until the said challenge is over.
  • Obfuscating Stupidity: He made repeated use of this, particularly drawing on his "Osakanisms" to cover up whenever he uses Conan's real name by accident.
  • Oblivious to Love: Heiji is apparently utterly incapable of realizing his feelings for Kazuha or vice versa; even going so far as to believe the jealousy he felt when she flirted with a magician was just a leader's concern for his follower.
  • Red Baron: Known as "The Detective of the West".
  • Red Oni, Blue Oni: The Red Oni to Shinichi/Conan's Blue Oni.
  • The Rival: To Shinichi. They're close friends and usually work together in cases, but on several occasions Heiji tries to prove he can solve the case before Shinichi. Most of the time, he fails.
  • Secret Keeper: A rather bad one, however, constantly blurting out Conan's real identity and then scrambling to cover it up.
  • Single-Target Sexuality: In a reverse situation from Shinichi and Ran, it took Heiji a while to realize his romantic feelings for Kazuha. However, even before coming to realize his feelings, Heiji has never shown interest in any other girl.
  • Surprisingly Good English
  • Tall, Dark and Handsome: Like Shinichi, Heiji has been known to fit this.
  • Teen Genius
