- “I am not worth five people.”— Jonas
During the Covenant invasion on Earth, he was calmly giving away his kebabs to the crowd escaping from the city. He had decided to stay in the city, as he realistically had no way to escape as he was too heavy to walk long distances, or would take too many seats on a bus, train or boat. He claimed that he could take up to five seats in public transport vehicles. In the ensuing panic created after the Covenant arrived, Jonas embedded his cleaver in an angry motorist's vehicle hood, and proceeded to use the newly-cut hood as a seat, arguing that the motorist's horn was frightening the children. Sadie Endesha tried to convince him to leave the city, but he insisted that Sadie escape first, to find her father. She vowed to return for him with a forklift. However, she never did, and his ultimate fate is unknown.
- The Superintendent uses Jonas' words to persuade Sadie to leave New Mombasa; instead of 'I am not worth five people', it is 'I am not worth your life, my brave warrior princess'.
- Jonas is voiced by Richard Zeman.
