Shinichi and Hattori are detectives.But they have some same points and different points.
1.Same point:
-They always patient to find clue.
-They all...handsome(Shinichi is better)
- They don't want their fame are broke por some one(like Mouri Kogoro)
2.Different point:
-Shinichi doesn't want the perpetrator die.
-Hattori think he is the best detective and want to win Shinichi.
-Shinichi can "play" some dangerous game to have some clue.
Those are my opinion.You can see:I'm like Shinichi the best.
