NO.1: Kaitou Kidd, IQ 400. In "Magic Kaito", Detective Hakuba picked up a piece of Kaito Kid's hair that was lost at the scene. Hakuba took it for analysis and came to the conclusion that the owner of this hair has an IQ of up to 400. Although his intelligence is 400, which is outrageous (no such creature has ever appeared in the 20 billion years of the universe), he is the only one among the characters in "Conan" whose IQ has been clearly recorded.
NO.2: Haihara Ai, IQ 200. When Ai and Conan are together, the latter always steals the show, but this is limited to solving crimes. Conan is certainly shrewd, but in Japan, although there are very few people whose reasoning ability is comparable to Conan's, there are still some. However, the person who can invent this lovely drug APTX4869 is unprecedented, if not unprecedented. If we only consider the scientific value of this drug, it would be easy for Hui Yuan to win the Nobel Prize. If it weren't for Kaitou Kid's hair, I really wanted to award Haibara the championship in the "Conan" character IQ competition, but it's a pity that Kaitou Kidd won this honor, and Xiao Ai had to settle for second place
NO.3: Yusaku Kudo, IQ 165. Although it is said that the waves behind the Yangtze River push the waves ahead, but judging from the plot of "Conan", Conan is still somewhat inferior to his father. Excellent works are not only insightful, but also wonderful. His reasoning is like divine help and indestructible, and his novels are even more brilliant and highly praised. His creative skills are something Conan does not have. Moreover, in the several "father and son battle" cases in "Conan", Yusaku always figured out the answer before Shinichi. It can be seen that Mr. Kudo Yusaku's IQ is slightly higher than that of his son Kudo Shinichi.
NO.4: Edogawa Conan, IQ 160. The protagonist detective in "Conan" only ranked fourth. Conan fans must be very depressed. But considering that there are so many masters in "Conan", and the people with the highest IQs in Japan are all gathered here, Conan is not unfair. I want to focus on how the data of 160 was obtained. Friends who are familiar with another Japanese detective mystery anime "Shounen Kindaichi's Incident Book" should know that Kindaichi's IQ is 160 (this is well-documented). Using this as a reference, Conan's IQ should also be 160, because I think Their intelligence levels are evenly matched.
NO.5: Hattori Heiji, IQ 159. To be honest, I feel a little aggrieved for Heiji. Everyone talks about Higashi Kudo's Western Clothing Department. Why can they differentiate themselves even though they have the same name? Maybe Shinichi and Heiji's IQs are really about the same, but a sentence borrowed from Lotus Leaf can distinguish the two: "Why are you just like a magician's assistant in front of Kudo?" I believe Hattori's point. The sentence "This is Tokyo, naturally I can't steal Kudo's limelight", but the fact is the fact. The protagonist of this drama is called Edogawa Conan. Maybe in the future Aoyama will draw a companion chapter to "Detective Conan" - "Detective Hattori", then Hattori will have a chance to reverse the case.
