Jonah is a scientist who was hired by the Sphere to design an Anti-Seijin holding cell on the Monolith for a very special Seijin. However, he heard that he would be executed after the job was done, compelling him to escape. He was intercepted by the pirates who asked for his help to sneak Mahad and Lena onto the Monolith. Instead, he took off in the Hyperion but was captured by Diwan. After a series of fights on the Monoliths, Jonah escaped with Mahad and Lena so the Sphere could never use his genius. Jonah was seen in the episode "Infiltration."
