Solicitations on the Diamond Comic Distributors website have named him as 'Baz', reports Newsarama.
The description of Geoff Johns and Doug Mahnke's Green Lantern #13 reads: "Baz, Earth's new Green Lantern, battles The Justice League!"
The character was teased in the publisher's Free Comic Book Day offering, which laid down the foundation of the future 'Trinity War' storyline.
Baz will debut in September's flashback Green Lantern #0.
He will apparently play a key role in the forthcoming 'Rise of the Third Army' crossover, which will run through the pages of the various Green Lantern titles.
Green Lantern #13 will be released on October 3.
