Ghost Rider is the name of several fictional, supernatural
anti-heroes in the Marvel Comics universe. Marvel had previously
used the name for a Western character whose name was later changed
to Night Rider and subsequently to Phantom Rider.
The first supernatural Ghost Rider is stunt motorcyclist
Johnny Blaze, who, in order to save the life of his mentor,
agreed to give his soul to Satan (later revealed to be
an arch-demon named Mephisto). Instead, his soul was bonded
with the entity called Zarathos. When emitting Zarathos's
powers, Blaze's head became a flaming skull and he wielded a fiery
motorcycle and trademark blasts of hellfire from his skeletal hands.
He starred in an eponymous series from 1973-1983.
The subsequent Ghost Rider series (1990-98) featured Daniel
Ketch as a new Ghost Rider. After his sister was injured by
gangsters, Ketch came in contact with a motorcycle which had somehow
been mystically enchanted to contain the essence of a "Spirit
of Vengeance." This spirit had originally been a Puritan man
named Noble Kale, an ancestor of both Blaze and Ketch. Johnny Blaze
reappeared in this series as a supporting character and was revealed
to be Ketch's brother.
