Trivia

 * After the announcement of the cast, the choice for Raven led to some jokes online since her voice actress already shared another role with fellow Teen Titans cast member Tara Strong (Harley Quinn), leading to fans jokingly tweeting if Tara was to replace her as Starfire.
 * That one ended up to not be true, since Mae Whitman voices Starfire in sister series Titans: Legacy.
