Dwight first appears in Old Man Logan part 3 (Wolverine # 70) and stops Hawkeye and Wolverine while they are driving East. Dwight operates out of Des Moines, Iowa by controlling a bridge he has named Dwight's Toll, making any who wish to cross pay up under the threat of death. Hawkeye gladly pays.
Dwight wields the Ant-Man held, which allows the wearer to mentally control ants. Dwight uses the helmet to control an army of several million ants to coerce those who would like to use his bridge with the threat of violence.
