Copy Ninja Rock Lee?! (コピー忍者ロックリー! Kopī Ninja Rokku Rī?!) is Chapter 4 of the manga.
Neji Hyuga meets up with Tenten, in search for Rock Lee. It is revealed that Lee is climbing on the side of a wall, while tied to three boulders, in order to train his taijutsu.
Soon after, they speculate Might Guy and Kakashi Hatake who were about to enter into one of their famous "heated" battles. Guy, who is apparently sick, sneezes, and Kakashi uses the opening to attack him with the One Thousand Years of Death technique, which is merely another term for the game Kancho. Guy becomes debilitated by it and takes a break, so Kakashi temporarily assumes Guy's position as team leader.
After believing that Kakashi had now defeated Guy twenty times, Lee ponders whether or not he needs a new mentor and asks Neji to help him practice the One Thousand Years of Death technique to which Neji declines outright, so Lee moves on to practice on a dummy.
The next day as Tenten and Neji wait to set out on a mission with Kakashi, Lee arrives dressed exactly like Kakashi, even with a copy of Icha Icha in hand. After the initial shock, the team sets out with the assumption that Kakashi would catch up with them eventually. Unbeknownst to them, Guy watches on from behind a post.
They soon encounter shinobi from Yugakure, who mistakes Lee as the actual Kakashi Hatake, and hearing that, Lee pretends that he is Kakashi. The ninja ask for proof that he is Kakashi by showing them his Sharingan. Lee lifts up his forehead protector to reveal a Sharingan, which in actuality is a contact lens, much to Tenten's shock. As Tenten turns to Neji, he states that with contacts he could finally perfect that technique: the "Byaku-Sharingan", which only served to disappoint Tenten.
As the enemy shinobi realize that there is no scar over Lee's left eye, they call him out as a fake. However, Lee uses his speed to get behind the ninja and initiates the One Thousand Years of Death technique, but is unsuccessful because of metal plating that the ninja had put there to protect that area. The said ninja then claims that Sakumo Hatake had used the technique on him in the past, in which Tenten states that that is a lie.
Soon after, the ninja surround Lee, and Tenten calls to Neji for them to aid Lee, but Neji is unable to see due to contracting dry eye from the contacts. Just as the situation looks dire, Guy appears, declaring that he would not let anyone harm his subordinates, despite being in bad shape himself. Kakashi comes next and informs Lee that Guy came all the way out there in his sick state to show Lee the path he should walk as a shinobi. Lee tears up and is persuaded that Guy is the most amazing after all.
Lee, Guy and Kakashi then use the "Three Thousand Years of Death" technique and send the shinobi flying. It is later cleared up what Kakashi meant by "twenty consecutive wins", since he was only referring to the hero in the book he is reading. Lee and Guy tearfully reunite and are later seen training to use the One Thousand Years of Death technique on dummies.
