Amalgam Comics: Marvel Comics # 11- Spider-Boy Team-Up
While Scavulture (DC’s Scavenger and Vulture) attacks Spider-Boy, he’s suddenly trapped in a transparent box
Story occurs simultaneously with Challengers of the Fantastic
Spider-Boy finds himself in 2099 and meets the Legion of Galactic Guardians 2099 (Legion of Super-Heroes and Guardians of the Galaxy)
Spider-Boy must return to his exact time in 20 min or there will be a chronal collapse. At that exact moment the Frightful Five attack the Legion base and destroy the Time Square Generator which is how Spider-Boy got there
Spider-Boy returns to 2099 and this time he helps the Legion activate an old Phantom-Negative Zone Projector as well as discuss the effects of spider DNA on a human subject
He then returns again to 1997 where the Legion show up in that period for the first time
Out of nowhere, Kang the Time Conqueror (DC’s Trapper and Kang the Conqueuror), leader of the Frightful Five, attacks Spider-Boy because he is a Living Nexus of Realities and plans to absorb the amalgamated life energies within him hoping to become master of the Omniverse
While absorbing the life energies, Spider-Boy splits into Spiderman and Superboy temporarily and a future Spider-Boy arrives to assist him
Spider-Boy 2099 is a kid who the original saved when he returned to ‘99 and placed him into the Phantom-Negative Zone after being critically injured by Scavulture and injected with spider DNA that Spider-Boy will research one day
Kang took Spider-Boy into Limbo where he was absorbing his energies and where Spider-Boy 2099 was able to access because of 100 years of exposure in the Phantom-Negative Zone
