History in the comics
"Peter" emerged from one of the Jackal's pods. Believing himself to be the genuine Peter Parker, he confronted Spider-Man, Scarlet-Spider and Kaine. He became obsessed with proving to Mary Jane Watson that he was the real Peter and once Peter, Ben, Kaine and MJ were all near him at one the Jackal's programming kicked in and his shae shifting powers activated and he turned into a monster who was killed when Kaine threw a propane truck at him.
Spidercide at his peak can lift approximately ten tons. Spidercide is also capable of crawing on walls and has spider sense similar to Spider-Man. However, unlike Spider-Man, Spidercide is able to control his molecular structure to extend his limbs similar to Mr. Fantastic, although not so extensively. He can also control the density of his body tissue to make him more resistant to all forms of injury. Spidercide can also transform his fists into hammers, spikes and other weapons.
