Happy Harbor is a small municipality in the state of Rhode Island on the east coast of the United States of America.
Years later, it was revived for a covert operations team composed of Robin, Aqualad, Kid Flash, Superboy, and Miss Martian. While the team was out flying in Miss Martian's Bio Ship, Red Tornado learned an emergency alert was triggered at the Happy Harbor Power Plant. The team investigated and discovered it was being attacked by a new villain named Mister Twister. Their battle caused much property damage to the plant, harbor, and city.
On August 8, 21:53 EDT, Young Justice set up a perimeter around Happy Harbor High School, home of the Hornets, to safeguard Dr. Serling Roquette while she completed a virus to neutralize The Fog. Upon an incursion by Cheshire, the team moved Roquette across the town to the Sandbar internet cafe while Miss Martian posed as Roquette at another location.
