Janet uses her ability to bend gravity to enable her already incredible feats of strength, lifting her own heavy body high into the air with ease, and crushing anyone who stands in her way. Combine this with her can-do attitude and willingness to not ask questions. and she makes for an ideal hired muscle.
No to say muscle is all there is to her. Sure she can punch through walls and bend steel beams, but one doesn't master the pull of gravity without a few book smarts, and it would be a fatal mistake to assume the muscle of the operation isn't capable of forming her own personal schemes too.
Her birthday is June 8th
Her favorite food is poppyseed muffins
She's overwhelmingly proud of her figure.
