Hunter x Hunter Heads to Toonami

Though the announcement was too close to April Fools’ Day for comfort, the 2011 Hunter x Hunter anime is officially coming to Toonami. The hit action series makes its debut on the block on April 16, and will feature the English dub cast that licensee Viz Media previously announced.

That dub includes Erica Mendez as Gon Freecss, Cristina Vee as Killua Zoldyck, Matthew Mercer as Leorio, Keith Silverstein as Hisoka, and Erika Harlacher as Kurapika.
