I used to only know Mr. Arcelus for his work on 4kids dubbed animes such as Shaman King (Yoh), Yugioh (Espa Roba, Rex Raptor), and Winx Club (Timmy, Palladium). The Yugioh roles were minor, but Yoh was the main character on Shaman King, and he really proved himself worthy of the role. I can't imagine a more perfect voice for Yoh. While I'm not a fan of Winx Club, I have seen it, and I have heard his voice acting on it, and in my opinion, Mr. Arcelus is the best actor on the whole show. Considering how talented a lot of the 4kids VA's are, it's not surprising.
Recently, I found out about Mr. Arcelus's other acting credentials, namely the Broadway ones. I did not see his performence in Rent, but I know the character Roger is one that takes a very talented actor and singer to play. Currently, Mr. Arcelus is playing Fiyero in the tour of Wicked. I was lucky enough to get tickets to the show just before they sold out, and I got to see him perform in person. Words cannot describe how AMAZING he was. He went from stuck-up to in love, to angry, sad, and every emotion in between. He sang; he danced; he swung in on a vine!
Any performance Seabastian Arcelus has given has been absolutely incredible, and any character he has played has been blessed to have him portray them.
