Gravity

Greg Willis is born and raised in Sheboygan, Wisconsin. During the summer after his high school graduation, while on board his family's yacht, Greg is sucked into a mysterious black hole. He is found hours later by his parents, unharmed. After the incident, Greg finds that he is able to manipulate the gravitational force around his body and nearby objects. Looking to take advantage of his new powers, Greg moves east to New York City to study licensing and merchandising at New York University, and becomes a marketable member of the superhero community known as Gravity!

As part of Tony Stark's 50-States Initiative project, Gravity was assigned to the Great Lakes Avengers.
