"I don't know how to use Google".
Famous Canadian author. There, I solved it.
Also Dante Basco is not that obscure. Rufio was a biggish deal before Homestuck, hell he was going to get his own movie. he also voiced Zuko, as said (which I didn't actually know at first). Involved with the Legend of Korra too. So he's had a decent amount of popular stuff.
