Soren : I went through my Ghost Rider comics of years ago and besides "the Orb" and an assortment of other devilish characters, could not find Mr. Fonda. Fonda was still quite the "biker icon" at the time of Ghost Riders debute even though Easy Rider was more about a drug pusher looking for the meaning of life than a care free biker on an adventure. I have found no character with the likeness of Mr. Fonda in any of the 1st 20 issues of the Ghost Rider comics from Marvel Inc.
