Chronos (whats-his-english-name-again) has the same voice actor as Spongebob Squarepants. Sadly enough, he doesn't have an Italian accent like in the original, but it sure does some good crack. ^^
And now stop and think for a second about Chronos wearing the Squarey-panties and flipping hamburgers on his duel disk...
(I kid you not. It was the first thing that came to my mind.)
We have other very familiar voices in there as well (I'm still trying to figure out most of them by sound, it's difficult). Bastion (? Mr. nearly the best) is our Kudou Shinichi/Edogawa Conan guy. Yuugi was himself (literally, the Yuugi-actor. We have different VAs for Yami and Yuugi, so it's easy to tell)
Well, that's it. I hope I don't bore you to tears with my constant observations about YGO. I have been posting quite a lot, lately. Oops.
*stalks off sniggering about Chronosbob Squarepants* XD
