Trivia: Sasuke Uchiha!

• Sasuke's given name comes from the legendary ninja Sarutobi Sasuke. Sasuke's surname, "Uchiha", is another way of pronouncing "uchiwa" (団扇, paper fan), which is actually the Uchiha clan symbol. Uchiwa can be used to fan flames, making the flame hotter — referring to the fact that the Uchiha is a clan of fire jutsu users.
• Unlike most characters in Naruto, Sasuke doesn't address anyone with honorifics at the end of their names (except to his parents, clan members, and Itachi when he was a child), like "Kakashi-sensei" or "Orochimaru-sama", something the Japanese would consider very insulting or rude.
• In the June 2006 edition of Shonen Jump, Kakashi remarked that, while Sasuke is a genius, he is dull to teach because he learns everything easily, compared to the less predictable Naruto.
• Although Sasuke's first appearance is generally thought to be chapter 3, he can actually be seen sitting behind Naruto in chapter 1, page 14.
• On the cover page of chapter 1, Sasuke is seen riding a hawk, which he later learns to summon. In most subsequent cover pages he is only depicted with snakes, another species he learns to summon.
• In the Naruto character popularity polls, Sasuke was placed in 3rd in the first, 4th in the second and third, and 3rd in the fourth. He finished 1st in the two most recent popularity polls, and in the third databook, which added results from the previous six polls, has Sasuke as the third most popular character overall with 33,632 votes.
• Sasuke is one of five characters to have always stayed in the Top Ten of every Character Popularity Poll.
• Sasuke's Mangekyō Sharingan is the only one that doesn't have three points. It consists of three overlapping ellipses, giving it six points. It is also the only Sharingan to have inverse colors; while most are red with black designs, Sasuke's seems to be black with red designs.
• Sasuke is ambidextrous: he has used the Chidori with his left hand, and used his sword and written things with his right hand.
• Each time Sasuke remembered his teammates from Team Kakashi, instead of giving him some sort of renewed hope, it has lead him further into darkness.
• According to the third Naruto databook:
  
  • Sasuke's hobbies are training and taking walks.
  • Sasuke wishes to fight against the upper ninjas of Konoha (originally, he wanted to fight Itachi).
  • Sasuke's favorite foods are omusubi with okaka and tomatoes, while his least favorites are nattō and anything sweet.
  • Sasuke has completed 16 official missions in total: 7 D-rank, 1 C-rank, 2 B-rank, 6 A-rank, 0 S-rank.
  • Sasuke's favorite word is "power" (力, chikara).
