The Sage is a character from the Chinese animated series Stitch & Ai, a spin-off of the Lilo & Stitch franchise. His real name is unknown.
An elderly bearded man, he is a wise sage that appears to Ai, Stitch, Jumba, and Pleakley at various points to subtly guide them to a greater purpose, which he never makes clear. He also gives Jumba ancient scrolls that contain information on ancient Chinese creatures, which Jumba uses to create new genetic experiments. He often speaks in a manner that is seemingly misleading, such as "answering questions with questions" as Pleakley points out in "The Scroll".
