Spider-Man spars with Nova, Power Man, Iron Fist, and White Tiger throughout the Statue of Liberty as part of a training exercise. After Spider-Man defeats them, he receives a disrupted transmission from Dr. Curt Connors, who tells him to head to Doctor Octopus's underwater lab. Although Spider-Man debates on whether or not he should bring his team, he asks them to accompany him, but they decline, stating they have other plans, but to call them if he needs to. The web-slinger questions his effectiveness as a team leader as he enters the lab. He comes across a trapped Dr. Connors, who warns him it is a trap. On cue, the Rhino, Kraven the Hunter, Beetle, and Electro attack Spider-Man and Doctor Octopus reveals to be the de facto leader of the group, the Sinister Six. Spider-Man questions this as only five villains are present, but Doctor Octopus presses a remote control, activating a device on Dr. Connors's neck that forces him to transform into the Lizard.
While dodging the Sinister Six's attacks, Spider-Man attempts to contact his team, but Doctor Octopus has jammed the signals. Spider-Man briefly distracts the Sinister Six and retreats into the tunnels, where he decides to divide them. He throws his voice in all directions and the six split into the tunnels. The hero traps the Lizard in webbing and encourages Dr. Connors to fight the transformation, which succeeds, but the rest of the group attack and Doctor Octopus once again forces Dr. Connors to transform. The hero fights off the villains while attempting to reverse the effects of the Lizard, but the reptile knocks him. Rather than killing him, Doctor Octopus decides to unmask Spider-Man. Kraven tells the Lizard to do the honors and he proceeds to.
However, the Lizard exclaims that Spider-Man is his friend and resists Doctor Octopus's control while attacking Kraven. Doctor Octopus orders Electro to stop the fighting and he zaps Rhino, enraging him. The Lizard attacks Beetle while Rhino knocks out Electro. The five start battling and Doctor Octopus tells them to stop and focus on Spider-Man, but the hero taunts the villain, stating he is a more effective leader until Doctor Octopus reminds him that he has no team. Rhino attacks Spider-Man, but the villain is tricked into flooding the underwater lab. Spider-Man floats to the docks and attempts to find his team while hitching a ride on a forklift, but the Beetle attacks.
Spider-Man drops construction materials on the Sinister Six and departs on a helicopter while J. Jonah Jameson exclaims the six are trying to stop the real villain, Spider-Man. The web-slinger discovers the helicopter is broadcasting and orders his team to rendezvous with him at the Statue of Liberty. However, the Sinister Six heed the call and attack Spider-Man at the site. The six easily defeat Spider-Man and tries to unmask him, but Nova stops them and is joined by the rest of the team. Doctor Octopus tells Spider-Man they will test which leader is more effective and the teams attack.
Spider-Man attacks the Lizard, Power Man takes on the Rhino, Nova challenges the Beetle, White Tiger clashes with Kraven, and Iron Fist battles Electro while Doctor Octopus taunts Spider-Man, stating he had chosen the team to rival Spider-Man's. Figuring this out, Spider-Man orders his team to take on different foes and he switches to attack Doctor Octopus. Nova switches to Electro, Iron Fist battles the Rhino, Power Man battles Electro, and White Tiger clashes with the Beetle. Doctor Octopus tell the group to hold their ground, but one by one, they are defeated. Doctor Octopus orders the Lizard to kill Spider-Man, but he refuses and attacks Doctor Octopus and he faints. The Lizard then attacks Spider-Man and retreats into the sewers.
Spider-Man chases the Lizard into the sewers proclaiming to change back, as the villain stands on a giant waterfall. He leaps, but Spider-Man traps his arm with webbing, stating he'll never give up on trying to save Connors, but the Lizard slashes the webbing and falls into the water below. At S.H.I.E.L.D., Nick Fury tells Spider-Man to stop beating himself up for the Lizard and reassures Spider-Man that he managed to capture five of the deadliest villains and they will find Connors and turn him back to normal. Spider-Man then thinks of what the Lizard had said to him, that he won't stop failing if he doesn't stop attempting to save him, to which Spider-Man says that he won't stop trying.
