Bleeding Cool understands that the Animal Man scribe is in line to pen The Robins, a new comic featuring the Dark Knight's sidekicks past and present.
Robin alter egos Tim Drake, Jason Todd, Damien Wayne and Dick Grayson will allegedly team up in the book, which is yet to be assigned an artist. The website cites a "well-placed source" as the origin of the news.
Lemire, whose works include Sweet Tooth, Superboy and Jonah Hex, signed an exclusivity agreement with DC in 2010.
He was appointed as writer on Animal Man and Frankenstein, Agent of S.H.A.D.E. following the publisher's 'New 52' relaunch.
DC is yet to officially announce The Robins.
