Origin
When Spider-Boy was able to save a boy named Mig-El Gand from a blast from a radiation beam, he found out that he was being poisoned by the radiation. Pete then put Mig-El into suspended animation for Pete to develop a cure in the future. Mig-El woke up after 100 years had passed and, in this timeline, Mig-El was not only cured by a spider serum made by Pete from the future, but also given the powers of a spider. Mig-El decided to use his powers for good and became Spider-Boy 2099. When Spider-Boy faced an extra-dimensional villain, Spider-Boy 2099 time-traveled to the present and, together with his predecessor, defeated the villain. Before going back to his own timeline, he told Spider-Boy that his life would never be the same when he’s married to the Insect Queen. In the middle of his superhero career, Spider-Man joined the Legion of Galactic Guardians of 2099.
Powers and Abilities
After being given the spider serum developed by Spider-Boy, it not only cured Mig-El of his radiation poisoning but also gave him powers based on a spider. These included superhuman strength, agility, super speed, wall-crawling abilities and the ability to fire spider silk from his fingertips.
