Jon Hartman

Jon Hartman is the brother of the tallest being involved in Transformers who isn't fictional.

Jon and his brother Karl wrote numerous Transformers pieces for publications like Lee's Guide throughout the 90's. They started BotCon back in 1994, so you're welcome. They also used to have possibly the largest and most diverse collection of loose and packaged Transformers products in the US, but at BotCon 2006 sold off vast swaths of it to pay for things like homes and marriages and whatnot. You know. Stupid grown-up stuff.

Fun Jon facts:
 * Named BotCon
 * Went into debt twice to keep BotCon going
 * Was not photographed holding soggy Actionmaster Predaking concept art found abandoned in Arby's parking lot
