Joe Wade
Joe Wade is the only character to operate as a villain under the Scarlet Spider alias. An undercover FBI agent assigned to investigate the second Doctor Octopus, he is discovered and turned into a hard-light holographic duplicate of Ben Reilly to ruin the latter's name. In his Scarlet Spider guise, Joe is actually trapped in a virtual reality chamber, and his thoughts power the hologram. Despite this, Joe is unable to stop himself from committing acts of violence. When the real Scarlet Spider attacks Doctor Octopus's lair, he damages the machine while Joe is still inside. The damage to the virtual reality chamber causes the grafts to malfunction, and Joe becomes a real mechanized Scarlet Spider with amazing powers. As the new Scarlet Spider, Joe is superhumanly strong and fast, and has claws on his fingertips; he can also fire webbing from his wrists, crawl up walls, and fire laser 'stingers' from his eyes.
