With Great Power, There Must Also Come Great Responsibility. Lately, that responsibility has brought only heartache for Peter Parker. Ever since Peter and Mary Jane Watson broke off their relationship, their friendship has been nonexistent-and Peter has been trying without success to win her back. Now, when a new villain with lots of power and zero responsibility explodes onto the scene, he has one more obstacle in his way. But even more important, how can Spider-Man fight the new mysterious foe named Geldoff if he can't even find a costume? Can a special appearance by the Ultimate X-Men help Spider-Man learn more about his new adversary?Bendis, Brian Michael is the author of 'Ultimate Spider-Man Irresponsible', published 0017 under ISBN 9780785110927 and ISBN 0785110925.
