Donatello llega a Gotham City, donde se reencuentra con sus amigos Batman y Robin en un momento que no es precisamente oportuno. Y es que la Liga de Asesinos ha decidido prescindir de Ra’s al Ghul tras el incidente con Shredder, y ahora la organización cuenta con un líder nuevo que es aún más temible que la Cabeza del Demonio. Los guionistas James Tynion IV y Ryan Ferrier y el dibujante Freddie Williams II nos traen la secuela del éxito Batman/Tortugas Ninja, un volumen repleto de aventuras, del humor habitual de estos mutantes y, por supuesto, de enemigos propios de dos de los universos de ficción más populares del mundo del cómic.
Prior to his first professional work, Tynion was a student of Scott Snyder's at Sarah Lawrence College. A few years later, he worked as for Vertigo as Fables editor Shelly Bond's intern. In late 2011, with DC deciding to give Batman (written by Snyder) a back up feature, Tynion was brought in by request of Snyder to script the back ups he had plotted. Tynion would later do the same with the Batman Annual #1, which was also co-plotted by Snyder. Beginning in September 2012, with DC's 0 issue month for the New 52, Tynion will be writing Talon, with art by Guillem March. In early 2013 it was announced that he'd take over writing duties for Red Hood and the Outlaws in April.
Tynion is also currently one of the writers in a rotating team in the weekly Batman Eternal series.
