Ulqiorra as played by Roger Craig Smith

So in this game released in 2007 everyone thought for the longest time, myself included, that it was Steve Blum playing Ulquiorra, due to none of the Bleach games having any English cast lists, but in reality he was played by Roger Craig Smith using the same voice he would later go on to use to play the character Noba in the Bount Arc.
Not long after that when Ulquiorra made his anime dub debut proper he was voiced by Tony Oliver, which was honestly for the best because no one can match his excellent performance. STILL, this sticks out as a very interesting curio of the AniGame world.
