Detatchments by using the power of the Shikon no Tama.
Kaseyu: Then why the hell didn’t I know this, and why did you just tell me now!?
Naraku: Because I’m evil, and it helped your powers grow.
Pilmo: Well, yeah, but just for that, I’m going to kill you and free Kaseyu!
Naraku: You can’t beat me, weakling!
Kaseyu: He does have a point, I’m sorry to say.
Pilmo: Kaseyu…! I thought you were on my side!
But who would want to get bruises if they were that pretty, huh?

Naraku does not usually wish to involve himself in physical fights, and instead creates living detachments from his own body to do his dirty work. Some people think this is a cowardly method of fighting, but the more mature Inuyasha fans know that he does it just to further his role of the story’s “mind-fucker”, because smart fans know that Naraku could wtfpwn Inuyasha’s flaming ass if the homo would stop being a pussy and actually present himself as a threat to Naraku.
Even though Inuyasha is the most epic piece of fail on the planet, Naraku is one of the most badass antagonists in manga literature, and it’s a shame considering the story that he’s in.
