DC Comics' Green Lantern Annual #1 gave readers a first look at the mysterious character, who has been alluded to in the title for some time.
"Who The First Lantern is and what his role will be in the upcoming Green Lantern universe will come into play very, very quickly," Johns told The Source.
"The being inside has been imprisoned... for a long, long time. The Guardians consider him their greatest threat, but also their greatest source of power. Whether he's friend or foe will be up for debate, but regardless he is one of the potentially most dangerous beings in existence."
"In Green Lantern Annual #1, readers got their first glimpse at The First Lantern, someone who's been locked away for a very long time - for a VERY good reason," added editor Matt Idelson.
"His presence in this story is the catalyst for something very bad, and yet his story is only going to grow from here."
Green Lantern Annual #1 served as the prologue for the 'Rise of the Third Army' crossover, in which The First Lantern will play a major role.
The character was mentioned as far back as the pre-New 52 crossover 'War of the Green Lanterns'. His true identity remains a mystery.
