Jon first appeared in the episode; Hammer & Fail (Part 1, Rival Builders). He is seemingly a positive version of the character; Tom. His last appearance and death was in The End: Part 2; he was killed by the missile (or wreckage) launched by Tord's robot
He carried a resemblance to Tom, the difference being, Jon had smaller eyes, smoother hair, and a jacket instead of a hoodie.
Though it may not seem it, Jon did not have pure-black eyes like Tom. Instead, his pupils were so thick that they would almost always cover the iris and sclera (white part of the eye).
He wasn't as courageous or intelligent as Tom, as Eduardo constantly insulted him and attacked him because of his lack of intelligence. Sometimes Eduardo scolded him even when he was right, showing that Eduardo just might dislike Jon in general.
Overall, Jon's personality was the exact opposite of Tom's.
In "Saloonatics", one of Jon's ancestors, Juan, is shown. Despite apparently being Mexican, Juan still carries an English accent.
In "The End (Part 2)" Jon was killed by a missile launched by Tord's robot. He died in the arms of Eduardo, his last words being "Something", laughing weakly, and then dying while Eduardo cries. In the post-credits scene of Part 2, Jon is a ghost and criticizes the Sinister Guy; tells the children he is perfectly fine; but then realizes he is a ghost and becomes extremely disappointed.
