According to the search results, Jay is still in Ninjago: Dragons Rising. In the first season, all 16 realms have merged into Ninjago, resulting in everyone being displaced, including the ninjas. In the last few episodes of the first season, Nya and Kai find Zane. While Cole has been confirmed to appear in the second part of the first season, it is unclear in which episodes Jay will appear. However, Jay has a set, and his voice dub actor confirmed he will be playing Jay again.
