Starkaþr (a Green Lantern; dies in flashback)
1882. Abin Sur arrives, weakened, on Earth in pursuit of a galactic despot.
He is saved from a trio of bounty hunters by Marshal Jordan, and the
two of them search for their prey together. Sur is prevented from using
his power ring for extended amounts of time, and also encounters
prejudice as an 'injun' on account of his skin colour.
The two of them arrive in Coffin Springs, where the bad guys have
the sherriff and a large amount of the population under their combined
thumbs, and are soon aware that they are being pursued.
