is undertaker based on the WWE's Undertaker?....me being a 팬 of both 아니메 and the WWE undertaker i have to wonder

no not at all, i don't think they have WWE in japan, undertaker from kuro is a person all his own ^_^

well i can tell u right now that the undertaker for black butler is younger......

No, an Undertaker is simply someone who tends to the graveyard. The 아니메 Undertaker also works as a mortician, and Ciel's informant.

no, nope
