Anthony Davis aka the Ringer was a minor criminal who tinkered with a suit with ring-shaped weapons. He was easily stopped by Nighthawk after breaking into a safe. During the fight, Nighthawk damaged Davis' teeth, and it took extensive dental work to repair his mouth while he served time.
Disillusioned and wary of superheroes, he asked the Tinkerer to upgrade the armor design. Ringer intended to sell the new armor rather than continue committing crimes. While the Tinkerer was working on it, the N.Y.P.D. surrounded the workshop. Ringer managed to sneak in and put his armor on, but was surprised by the Beetle, who had also come to get armor upgrades. Beetle forced him to battle Spider-Man. A modified version of Ringer's own explosive ring was wrapped around his torso to make him comply. Ringer was easily beaten and the device triggered. However, it did no damage. Beetle had simply used Ringer to gain data on Spider-Man for use in his own suit.
Vowing to get away from superheroes, Ringer moved to the Midwest. Ringer was one of many criminals called to a Bar with No Name in Ohio by Firebrand to meet about the threat of Scourge. However, Scourge was secretly the bartender. All who showed up were killed.
Leila Davis blamed both Spider-Man and Beetle for his death. When she joined a group of other villains in attempting to kill Spidey, she was saved during the fight by her husband, who appeared as the cyborg Strikeback. Davis revealed that he had not actually died in the Scourge's massacre, but was barely alive when A.I.M. agents investigated the murder, seeking information on the technology used by the dead criminals. AIM created a new cyborg body for him, and he worked for the organization for some time before striking out on his own. As Strikeback, Davis was a much more skilled fighter than he was as the Ringer defeating the team.
