We know that Hattori has about 1-2 abilities whenever we see him in the series, Detective Skills most commonly. But ah.. he has wait, 1, 2 ,3...oh no, I put a chemsha bongo featuring Hattori's abilities and I made the correct answer 3! Damn! It's supposed to be 4, damn it!
Anyway, as what I have said, Hattori has 4 abilities. Those are:
1. Detective Skills (Always Seen)
2. Kendo (Sometimes Seen)
3. Motorcycle Riding Skills (Rarely Seen)
and, his Most Special Ability
4."Can Guess a Woman's swimsuit Without Even Looking" Skill (Seen Once)

I hope wewe remember what episode did Hattori showed this ability (the 4th). I swear, he, Conan, Kazuha and Ran are at the beach. One zaidi thing, I think he described Kazuha's swimsuit pattern as that of a white tiger's stripes.

This is all I could say today. Thank you.
