kakashi always was better and cooler than gai, so they became :frenemies:
:P
Sasuke is naruto's rival, Sakura's crush, Kakashi's student and Itachi's brother.
They become subordinates instead of teacher-student so i guess you could say that.
Tobi is Kakashi's old team mate and rival, Obito Uchiha, as was revealed in manga issue 599.
Kakashi Hatake's primary rival is Might Guy. Their rivalry is characterized by friendly competition, particularly in terms of physical prowess and skills, with Guy often challenging Kakashi to various contests. Despite their differences—Kakashi's laid-back demeanor and Guy's energetic personality—they share a deep mutual respect and camaraderie as ninjas. Their rivalry adds depth to their characters and showcases the themes of hard work versus natural talent in the "Naruto" series.
Gui Sensei is a huge dork, but he is also very very talented. He is also Kakashi's "greatest rival." Seeing that Kakashi took Kakuzu out, I believe that Guy could also handle him.
Nextel, Cingular (now AT&T), and a bunch of other "guys".
You to have a tag battle with them with your rival as your partner.
Copy Ninja Kakashi and Kakashi of the Sharingan
Rin Kakashi's former team-mate does (she's a medic) does - the eye is taken from Obito Uchiha (the last member of the squad - which was lead by the later Yondaime Hokage) who is dying and want's to help his friend in his last minutes :)
when obito gave kakashi the sharingan the sharingan evolved as kakashi grew besides kakashi is the son of the white fang so kakashi's bloodline is from powerful ninjas
No, Kakashi doesn't have a daughter.
Kakashi was created in 2001.
