The Dynamite Entertainment published series will feature the untold origin of the masked crime fighter, and serve as a companion to Kevin Smith and Brett Matthews's upcoming Green Hornet title.
The Green Hornet - featuring newspaper publisher and secret vigilante Britt Reid and his companion Kato - originally debuted as a radio show in the 1930s, which went on to spawn various comics, television shows and movies.
"[Green Hornet: Year One is] gonna involve a mixture of 'present day' adventure - 1937, that is - and then flashbacks to both Britt's and Kato's respective pasts," Wagner told Comic Book Resources.
"The first year's narrative is divided up into two six-issue story arcs. In the space of those two storylines, all the elements of the original Green Hornet will be laid in place."
In the series, Wagner (Grendel, Madame Xanadu) will attempt to unravel Reid's motivations and explore why he chose the life of a vigilante.
"Unlike most of his masked, lone avenger colleagues, the Green Hornet is not only wanted by the police for his illegal activities, he actively cultivates the perception that his masked persona is, in fact, a self-serving criminal, little better than the mobsters he opposes.
"So that odd aspect, combined with the factors that would inspire a young, successful newspaper heir to this unusual lifestyle are - I feel - the real essential elements of the Green Hornet."
Green Hornet: Year One will feature art from Aaron Campbell (The Trial of Sherlock Holmes).
