Jon "JonTron" Jafari is a YouTube Game Review host who is known for reviewing bad games and sometimes even movies on his main channel, JonTronShow. He is known for his eccentric personality, shouting out numerous non-sequiturs during his reviews. He's also commonly associated with his cyborg parrot, Jaques. He's also a founding member of the video game network Normal Boots, of which The Completionist is also a part of.
He started a secondary channel, Game Grumps, with Arin "Egoraptor" Hanson, but on June 25th, 2013, he left the show. Since then, he has started working more on his main channel. In 2018, Jontron formally left Normal Boots in order to focus soley on his own show.
Jon was in Episode 4 because he has been known to be a massive fan of Shadow of the Colossus. Jirard recognized this, and invited him to make a cameo on his show.
According to the wiki for his old channel Game Grumps, Jon has since stated that this was a misunderstanding between them, and his title was actually "the Pitz-pletionsist". (Pronounced "Peetz-plee-shun-ist")
He has most recently appeared in Episode 100 in which he helps free Jirard and Greg from Sonic 06.
- Jon and Jirard attended rival high schools, and hung out with one another during and after this time.
- When he was a child, Jon once got in trouble for teaching one of his neighbors the F-word.
