Dr. Agasa

Dr. Agasa lives next door to Shinichi Kudo. On a list of 'craziest professors', he'd be a contender for a spot near the top. He's a genius inventor, and his gadgets often help Shinichi/Conan out of a tight spot. He was the person to learn of Shinichi's 'condition', and was the one to convince Shinichi to keep his identity a secret. He also helped convice Ran Mouri to let Conan stay at her house.

Some notable gadgets and inventions of his include:

 * The super-sneakers that allow Conan to kick far more powerfully than would be possible with the body and strength of a seven-year-old.
 * The voice changing bow tie that allows Conan to imitate any voice he chooses.
 * The glasses that can track the locator for up to twenty miles, and also have a built-in receiver for a bug, allowing Conan to eavesdrop much more safely.
 * The stun-gun wristwatch that allows him to knock out anyone, though it only holds one needle that he usually saves for Kogoro Mouri in order to reveal the criminal.
