Jonah J. Heston is the new host of MST3K in Joel Hodgson's revival of the series. He is stranded on the Satellite of Love alongside Crow T. Robot, Cambot, Gypsy, and Tom Servo in the service of Kinga Forrester (who considers him a "big stack of flapjacks").
Jonah was employed by the Gizmonic Institute as a Backjack driver. While transporting the largest cache of precious meteors the world had ever known he was captured by Kinga and her minions, after he responded to a fraudulent distress call intended to lure him into her experiment.
During Experiment #1101, Martha Masters spoke admirably about Jonah, describing him as being "a natural born gizmo-crat" with an independent streak that "could get him into trouble". Her associate Drake agreed, adding that he had heard that Jonah "operates outside the system, but he's effective".
Throughout Season 11, Jonah was portrayed as good-natured and amiable.
- The name "Jonah Heston" is in keeping with the MST3K tradition of giving the human subject of the experiment the same first name as the actor portraying them.
- The last name "Heston" would seem to be inspired by the famous actor Charlton Heston, who starred in several popular science-fiction/adventure films including the original Planet of the Apes, Soylent Green, and The Omega Man--an influence on the creation of MST3K.
- Jonah's Backjack is powered by a percussion drive engine of his own design. His drum kit seems to be the ship's secondary form of propulsion.
- Jonah can be seen knitting a red space suit in nearly every episode. During the end credits sequence of the finale a small figure in a red spacesuit can be seen walking along the Satellite of Love's exterior. Presumably it is Jonah.
- In Experiment #1114 - At the Earth's Core Kinga revealed that Jonah's full name is Jonah J. Heston. It remains unknown what the initial J stands for.
