When Nickelodeon got the rights of Winx Club, Lord Darkar (One of Jason's roles) was portrayed by Michael Dorn.
Jason was the only 4kids VA not involved with the Original Yu-Gi-Oh! series.
In the Pokémon series he went on hiatus with the other 4kids va's after 4kids lost the dubbing rights to Pokémon when season 9 started, but he later returned to voice Hamilton in DP082: Cream of the Croagunk Crop! and later became part of the new cast as Cilan.
Jason is best know for his role as the voice of Sonic in the "Sonic the Hedgehog series" (2005-2010).
