Rock Lee

Rock Lee (ロック・リー) was going to appear in Super Smash Flash 2 as a playable character, but was cut from the game due to fans' complaints. Because of that, none of his attack, nor special moves were even know. He and Robo Ninja are the only two characters that have been cut from the game, but Lee may appear as an Expansion Character.

Character description
During his time as a student in the Ninja Academy, Lee proved to have no talent for ninjutsu and genjutsu. He was mocked by his peers because of this. Even his teachers labeled him as "just another failure", and later the "Dead-Last" of his graduating class. Lee persevered, focusing on taijutsu.

When Lee eventually graduated he was added to Team Gai. During the team's first meeting he vowed to become a splendid ninja that specialized in taijutsu. Neji Hyūga laughed at him, but their sensei, Maito Gai, took a special interest in Lee. He encouraged Lee to keep at it and, in time, began teaching him powerful forms of taijutsu.

Lee is extremely energetic, single-minded, and over-enthusiastic. He is characterized as being the epitome of a "nice guy", having assumed many of Gai's personality quirks. One such trait is his apparent lack of common sense, believing at times that he can get what he wants by not wanting it. At other times, he takes copious notes, but forgets that he cannot check them during a fight. He also has a keen sense of honor, and respects his opponents, refusing to hold grudges against those who have defeated him, and returning favors to those that have helped him. This was shown by his readily befriending Gaara and forgiving him for crushing his arm and leg, which led to his hospitalization and nearly ended his career as a ninja. Lee feels others should show the same respect towards their opponents, and is disgusted whenever someone is unnecessarily cruel to their enemies.

Lee is known for speaking respectfully to others, being very proper in both English and Japanese language versions, and never using contractions or swearwords. He also uses formal Japanese, applying proper titles ("-san", "-kun", etc.) to anyone he meets. However, Lee refers his team-mates Neji Hyūga and Tenten just by their given names, implying that he is close enough to them to use such an informal way to speak to them. His relationship with Gai has also caused him to acquire many of Gai's traits; in addition to his personality, his dedication to his promises, as well as his belief that one cannot dislike food, are characteristics of Gai.

Lee's attempts to prove and better himself are recurring themes for his actions throughout the series. He is generally optimistic, and believes that, with hard work and passion, he can surpass a natural genius, but can be prone to depression when faced with setbacks. His drive to succeed was initially most evident with his rivalry with Neji, having learned from Guy that having a rival will provide incentive to succeed. Neji, a "genius" ninja, found Lee's efforts of bettering himself to be in vain, believing Lee would be stuck as a "failure" for the rest of his life.

As such, Lee resolved to prove Neji wrong, and confronted another "genius", Sasuke Uchiha, in an attempt to test his worth. While Lee maintained the desire to defeat Neji in a fight throughout the Chūnin Exam Arc, after Neji's eventual defeat by Naruto Uzumaki, another so-called "failure", Lee became less interested in this goal. Neji's rejection of his previous belief in fate might also have contributed to this, as he now respects Lee, believing that he will surpass the gifted with enough work.

Shortly after his introduction, Lee revealed that he liked Sakura Haruno, asking her to be his girlfriend and vowing to protect her immediately after they met. While she did not seem to share these feelings for him, and considered him weird, Lee maintained these feelings, and went out of his way to help her throughout the Chūnin Exams. Sakura becomes more appreciative after this, and punches Naruto whenever he insults Lee.

Despite this, Sakura does not seem to return any romantic feelings for Lee, as she refers to him with the more formal "Lee-san", as opposed to "Lee-kun". After the Exams' conclusion, Lee's interest in Sakura goes largely unaddressed in the manga. It is occasionally referenced in the anime, such as when Naruto fought Lee in the Lee's Dojo arc; Naruto transformed into Sakura, causing Lee to forget about the fight long enough for Naruto to attack him.

Gai's leadership has influenced Lee's training habits, which, coupled with his hard-working resolve, has allowed Lee to rapidly improve. When making a promise, for example, Lee assigns himself arduous tasks to complete in the event that he doesn't live up to his expectations. When this promise is broken, usually just barely, he ends up training to prevent it from happening again.

Since Gai began training him, Lee has worn extremely heavy weights on his ankles that appear deceptively light, increasing his strength at the cost of inhibiting his speed to levels that his peers still consider quite fast. Upon removing the weights, Lee's speed vastly increases, making it almost impossible to see his movements with the unaided eye. As such, the removal of his weights is a huge trump card for Lee. When he removed his ankle weights during his fight with Gaara, they enabled him to be the first person to ever bypass his defenses and strike him.

Lee has trained so extensively he can run and even fight while unconscious, using nothing but pure muscle memory. A flashback during the 'Curry of Life' filler arc, in Part I, highlighted that Lee can run in his sleep, due to training from Gai. Lee, as a properly-trained ninja, is more highly aware of his surrounding through his senses than a regular person would be: Highlighted in the 'Three-Tails Arrival' arc, when he was blinded by Kigiri's Vanishing Smoke Prison Technique, Lee called on his training from Maito Gai to be able to home in on Kihō through his 'spirit sensor'--which he had developed through "unceasing diligence and determination".

Trivia

 * Like his sensei, Rock Lee's character seems to be inspired by Bruce Lee, as shown from his name and having the same birthday. Additionally, Bruce Lee once received the same type of injury as Rock Lee did in the Chūnin Exams against Gaara, and he was also never expected to walk, much less fight again.
 * Rock Lee placed very high in the first four Naruto character popularity polls. He finished 5th in the first and second polls, 8th in the third poll and 7th in the fourth poll. But his popularity slipped in the last two polls, finishing 13th in the fifth poll and 18th in the sixth and most recent. In the 3rd Databook, a combination of the previous six polls ranked him as the 9th most popular character overall.
