of course Conan

Kaitou Kid is the best
I love you kaitou-sama

conan is d best .........
he can slove any case :-)

Kaitou Kid i lluuvv himmmm <3 xD

I love kid, He was my inspiration for my fanpop name.
But I do think that Kid and Conan/Shinichi are on the same level when it comes to brains, Heiji on the other hand are slightly under their level, But not by much. ^^

I Think That Kid Is So Smart ^^ ... Conan Comz In Secound Place And Heiji in Therd ... LoL It's Funny That U Have Kogoro Mouri On The Pick List ... I Dont Think His That Smart At All ^^

conan is the smartest cause he can solve any case even adults can't solve. But i do love Kid ...........

I'm going for Heiji Hattori. coz he also solve those puzzles that Shinichi couldn't figure out.

I'm going for Conan. Conan can solve almost all Kid's trick and get him down in these cases...

Every comment is good but I do think that conan is the smartest XD

Anyone that can stay disguised as someone for so long has got to be smart.

of course Conan

he is clever..
actually he and conan are both clever :)

Duh!! haha who would choose Mouri ?????

Conan-->heiji + kid + haibara..

well actually mouri did solved 1 crime case without conan help..if i wasnt mistaken..hey at least it was 1 case...LOL

kaitou is the best because even though conan always figures out his tricks, he always thinks ahead of conan by escaping. the ranking of the characters for me is (from smartest)): kaitou, conan/shinichi, heiji, vermouth, kogoro. i will freak out if someone piccks kogoro mouri.

ahaha i mostly agree with KaitouKuroba, but kogoro is actually quite smart when it comes to Eri related stuff lol
and personally, i like to think that shinichi-sama and kid-sama are on the same level...kid-sama just happens to be the one that has magic tricks with him ;)

omg yes deidara_1412 totally agree with u xD

ahahahaha who would choose mouri!:)

naw i just went with wut i thought was the best decision

I'd say Jimmy/Conan....

I like coco (conan) very much he is soo cute.....

even if i choose conan but I think shinishi has a special beauty

why are there both conan & shinichi??

kaito kid is smart, too. but conan is the best :D

it's impossible 4 me to choose -_-"

i totaly agree with kaitoukuroba, conan is smart, kaito too. they are same, but i am in kaito side:)

always kaito>.< and he's smart, conan can knows his tricks, but conan can't catch him, kaito use his brain and use his magic too. and he have a many voice.......... but i don't believe if his IQ is 400-.-

kaitou kid is the most smartest character in detective conan i ever seen

shinichi or conan since they're the same person

Shinichi and Conan are the same people but because Conan always in every episode so it must be Conan is the most smartest!! But Shinichi is the most smartest too.

well shinichis farther has tricked and out smarted him before and is sort of like a older shinichi^^

Shinichi and Conan are the same person...so I chose Conan because he's in almost every episode!! <3

.. all of them are smart .. really ... it's hard to choose .. but i salute on Kaito Kid because he's very smart by making riddles,puzzles,etc. and his I.Q is 400 .. (wow!) ♥^^♥ they are all smart ... but if you questioned me that "who is more smarter?: kaito or shinichi?" ... IT IS VERY VERY HARD TO CHOOSE .. hehe .. ♥^^♥

oh yeah!!

Nooooooo!!!! it's Yusaku Kudo!! how many times did he save Conan/Shinichi or gave him a hint that solved the case like magic? and how many times did he prove that Conan/Shinichi is false?

of course it's yusaku

isn't yusaku smarter than shinichi?

id say yusaka because he has outsmarted conan/shinshi on may ocasion however i dont think hes the smartest, there was that old man who was mouri and the head of the polices teacher who gave conan the clue to solve the mystery, hoever hes the smartest without going cookoo.

You now kaito is also smart if he is not how would he do he's tricks ( watch ova 4and you well see)

IF THSE OTHER CHARACTERS WERE SMARTER THAN KAITO THEY WOULD HAVE CATCHED HIM ALREADY XP!!!!!!!!!!!!

IF THESE OTHER CHARACTERS WERE SMARTER THAN KAITO KID, THEY WOULD HAVE CATCHED HIM ALREADY XP XP XP!!!!!!!!!!!!!!!!!!!!!!

I would have picked myself but Cool Guy/ Silver Bullet-Kun Figured out were That Person (The Boss) Lives just by hearing The song it sounded like when I tapped in his number. He was also smart enough to deduce That Ariade was me (or I was him) Just by seeing how nice I was I made no mistakes I was flawless yet he figured me out. He is the silver bullet to our organization.

And Heiji

Always the smartest for me :)

It has to be Conan and Kaitou....Kaitou is tooooooo smart!!!!!! and yes conan too

shinichi father is the smartest !!!!

1.Yusaku
2.Shinichi
3.Akai
4.Kaitou
5.Heiji
6.Vermouth/Gin

Yusaku is the smartest but he is experienced while shinichi is not so I will go with shinichi!!

Conan! Because he is so smart in anything but love :D

Conan is very smart detective and Kaitou Kid is a very smart, handsome thief. I love both Conan and Kaitou Kid

Yusaku!!!!

Oi Yusaku is the better detective Baka~~~~~~~~~😑😑😑😑😑😑😑😑

They are the same person!! I can't pick only one o them! I love them both but I love Conan more although they are the same. but I think they both have the same mind and the same way in thinking. Kaitou is very smart too!

well i have a huge crush on kaito kid

I got a mistook picture,peace

Sorry Kaito,but Shinichi is not without Heiji,so please.....

Sorry to Kaito fans also,but I go with HeiShin. I know you like Kai-kun but he would be caught someday. My decision states that I vote HeiShin because it's my favorite shipping.

Conan Edogawa Always

Heiji and Shinichi, cause they are the best team
