Quote: (from Obito) "A shinobi who violates the rules is scum, but a shinobi who abandons their friends is worse than scum."
With his Sharingan Kakashi has been able to copy more than one thousand jutsu, giving him the nickname "Copy Ninja Kakashi". As a result, Kakashi's arsenal most prominently features ninjutsu abilities and has led to him becoming a specialist in the field.
Kakashi has an ongoing, albeit slightly one-sided, rivalry with Might Guy, with Guy constantly proclaiming that Kakashi is his rival, and considering his and Kakashi's subordinates rivals. Kakashi, however, seems indifferent to their rivalry, which annoys Guy to no end.
Though he evasively says that he has "many hobbies" when asked about himself, he is commonly seen reading of "Icha Icha Paradise" (イチャイチャパラダイス, Icha Icha Paradaisu, literally "Make Out Paradise"), an adult and probably pornographic novel authored by Jiraiya that is a runaway bestseller in the Naruto world. Kakashi most prominently reads it while training and speaking with his team, and is later seen reading the second known volume in the series, "Icha Icha Violence" (イチャイチャバイオレンス, Icha Icha Baiorensu, literally "Make Out Violence"). In Part II Naruto gives him the new "Icha Icha Tactics" (イチャイチャタクティクス, Icha Icha Takutikusu, literally "Make Out Tactics").
Kakashi's Sharingan eye gives him a significant advantage in battle, as he can copy enemy techniques and use them as his own, as well as track and predict his opponent's movements flawlessly. Because it is a transplanted eye, his Sharingan eye is always active. While this would not be much of a problem for an Uchiha, his non-Uchiha blood causes it to use much more chakra than it should. Because of this, he covers it with his headband and only utilizes it in the most dangerous battles. Kakashi's use of the Sharingan is as good as that of Itachi Uchiha, though the aforementioned handicaps brought about by the nature of his eye make him somewhat weaker in comparison.
