to err is metahuman

To err is human, to forgive is divine.That's what Regulus Black tells himself. He was supposed to be the first Robin.The best Robin.That is, until his father discovers he has another son. A son older than Regulus; Sirius, who replaces him as Robin.It's not technically Sirius' fault that he's Robin… Regulus still blames him.Now at 19, Regulus has started training as Robin again and Sirius is now the charming vigilante known as Nightwing. This means that Regulus must learn to work with Sirius' team of vigilantes known as The Marauders and deal with their various… quirks.There he meets James Potter, Superboy, who makes Regulus feel like he can fly. Sometimes, literally.However, Regulus has to put these new and old feelings aside when a villain known as You-Know-Who has taken away the powers of the Justice League, leaving it up to the Marauders to stop him.
