Yusuke, especially circa de 1990's, was much more high pitched than Justin Cook. Now, his voice actor kind of uses the exact same voice for each character he plays…and you can kind of tell in the recent Japanese Yu-Yu Hakusho games where Yusuke sounds like Hayate or Shadi...
I actually know that he typically voice bishounen-esque characters, yea. But I was talking about his Yusuke specifically which sounded both deep AND gruff. Even though he'd kinda lose his voice and make high-pitched noises during the fights.
Okay, how about Sanosuke and Saitou from RK, then?
