The name of Kaitou Kidd was originally 1412, because Yusaku later wrote it too sloppily. . . Became a kid. . That is Kidd
The full name is "Phantom Thief No. 1412" (International Crime Code "1412")
Written on Kidd's encyclopedia (the following is the quotation)
"Named
The full name is "Phantom Thief No. 1412" (because its international criminal code is "1412"). Because the scrawled "1412" written by Kuroba Pirate General Kudo Yusaku is pronounced as "KID ." (See TV 76, 473), so the name "KID" was born.
. The name "KID" was mispronounced by Kudo Yusaku, Kudo Shinichi's father. It comes from the abbreviation of "1412" (TV 473 "The Adventures of Kudo Shinichi as a Boy (Part 2)"). In other words, Kudo Yusaku is the father of KID's naming (but Yusaku has never been named by Kuro). The plot of Yu Kaito’s name did not mention that Yusaku was Kaito’s “adopted father”). Kuroba Toichi once said to the then 7-year-old Kudo Shinichi: “I am your brother… No , To be precise, I am your brother..." [7] (TV 472, but this is just a humorous way of thanking Yusaku from Toiichi) So to some extent, Kudo Shinichi, the son of Toiichi and Kudo Yusaku Can be considered brothers.
