In ‘Amazing Spider-Man’ (1984) #251, Spider-Man is transported to Battleworld.

In a battle with Hobgoblin, Spider-Man and Hobgoblin are trapped in a building on fire. Hobgoblin awakens first and attempts to finish off Spider-Man who evades the attack. As the whole structure is about to collapse, Hobgoblin evades pursuit in his battle van. Spider-Man is in hot pursuit.

Writhing in pain and agony, Spider-Man evades certain death when Hobgoblin crashes through a bar. Spider-Man finally crushes open the top of the battle van and enters. A man-to-man confrontation ensues where Spider-Man is at a disadvantage since Hobgoblin previously suppressed Spider-Man’s spider-sense. As Hobgoblin is about to land in the final blow, Spider-Man’s spider sense returns. Spider-Man evades the attack.

Hobgoblin set the battle van on auto-guidance system and it is headed for Pier 83. The battle van crashes into the Hudson River with Spider-Man and Hobgoblin locked in battle. As Spider-Man attempts to save Hobgoblin, the battle van’s self-destruct mechanism engages and the battle van explodes later. Swimming to the surface, Spider-Man borrows a lamp from a frogman and plunges back into the waters. He searches for Hobgoblin amidst the debris and only finds “a ruined mask.”¹

A day later, Peter Parker parts with Harry Osborn after consoling him for his father’s death. Suddenly, his spider-sense goes wild, “like a bomb exploding within [his] head.”¹ Spider-Man says it’s the third monster tingle he has experienced in the last three days and he puts on his costume.

He states the danger is coming from Central Park. Web-swinging across trees, he arrives at Sheep Meadow. He finds a massive alien structure. Moved by a superior force, he enters the alien structure and vanishes.

Then, light erupts in space. The Beyonder introduces himself: “I am from beyond! Slay your enemies and all you desire shall be yours! Nothing you dream of is impossible for me to accomplish!”²

Galactus sensing the Beyonder’s power flies out of the construct in the intent to have Beyonder rid him of his hunger. Dr. Doom is in pursuit.

Mister Fantastic laments his pregnant wife and asks Captain America to be excused. Spider-Man follows Mister Fantastic and notices how depressed he is. Then he arrives at X-Men HQ.

Spider-Man overhears the X-Men’s discussion. They lament that even on Battleworld, they are not accepted by the Avengers and the heroes. They decide to put their plan in action. They are going to join Magneto. At that moment, Spider-Man storms through the window and swats Professor X and Cyclops. He exclaims he is going tell others about their plans. He webs Colossus and evades Rogue’s attack. He webs Rogue and Nightcrawler and also swats away Wolverine attempting to sneak behind him. Then he escapes evading, Cyclops‘ optic beam.

Spider-Man evades two punches that break through the wall and the ground. He then avoids a block of stone thrown at him. As Titania is about to slam a block of stone on Spider-Man pinned on the floor, Spider-Man evades with lightning speed. Then, with a flurry of a kick and punches, Spider-Man throws Titania through the concrete wall, outside Doombase, she falls to the ground and passes out.

After the battle is over, Captain Marvel finds a battered She-Hulk on the floor. Mister Fantastic places She-Hulk in a pod to regenerate. Meanwhile, Spider-Man finds Thor (and Hulk) exiting a room with his cape reconstituted. Spider-Man asks Thor and Thor tells him that Hulk found a “wondrous device.” Hulk tells Spider-Man it’s in a room where Spider-Man can just think to produce any clothing he wants.

Spider-Man heads into the room and is able to find the device. He concentrates then a black sphere is created on the device. Spider-Man’s spider-sense tingles and as he attempts to evade, the alien symbiote grafts itself onto Spider-Man’s costume. Then, Spider-Man’s black costume is produced on Battleworld. Spider-Man wonders why the costume came out black and says that maybe he was “subconsciously influenced by that new Spider-Woman’s suit!”³

At the ‘Marvel Super Heroes Secret Wars’ (1984) #12, the heroes have triumphed and prepare to leave Battleworld. As they prepare to return to Earth, they head to the same room where Spider-Man created his costume. Spider-Man asks the heroes if their costumes respond to thoughts. Human Torch responds “No–They’re just–Just clothes!” Spider-Man wonders to himself why his costume does.

Finally, the heroes are set to be transported back to Earth. Mister Fantastic explains the heroes are going to be beamed to the construct that transported them, then they will be transported back to Earth to Central Park or to whatever location the heroes concentrate on. Mister Fantastic says they will be sent by groups.

First are Spider-Man, Dr. Connors, Spider-Woman, Hulk and Magneto.
