it occurs to me that Marvel missed a chance to tie into pop culture. Imagine - a world-renowned professional cyclist, Tour De France winner and head of a successful charity. Though semi-retired, allegations of doping have dogged him for years, culminating into a witch hunt that destroys his reputation. Finally taking that stand in his own defense at the racing tribunal, the cyclist explains that they never found any evidence of doping, and never will - because he sold his soul to the devil to win. Then his face melts, leaving a familiar flaming skull.
Ghost Rider - just on a precision ten-speed bicycle. Maybe an optional yellow jersey.
