EDITOR'S OPINIONToday on the Bleach VC section we take a look at Ol' "Pachinko-Head" himself... IKKAKU MADARAME! Lets take a look here shall we?
Vic Mignogna- Vic's voice and performance for the role does suit Ikkaku's hot-blooded impulsive personality rather well. While Vic's work on the role does suit Ikkaku's calmer moments (in which he certainly has some) Vic's work does get to shine a bit more when Ikkaku is being incredibly hot-blooded. So in other words Vic's work as Ikkaku is a good example of his work and of the voice work in the show.
Michael Sinterniklaas - A pretty good attempt at trying to sound like Vic (oh sure its not hard to tell the difference but his voice still does work with the role well enough). While granted he seems to be doing a somewhat more somber performance as Ikkaku (but to be fair that is also a bit more due to the episode) but still Michael's performance seems to suit the role pretty well too.
Overall both of these guys are good but I will go with Vic Mignogna a bit more here.
