Toonami has confirmed that the One Piece anime will run on Adult Swim's Toonami block. A premiere date is slated for sometime this year. The announcement was made at Toonami's question-and-answer panel at Atlanta's MomoCon on Sunday.

Funimation's dub of the series previously ran on Cartoon Network's earlier version of the Toonami block from 2007 to 2008 after 4Kids' adaptation ended. Funimation has been streaming English-subtitled episodes as they aired in Japan since 2009.
