History
The Strength Force is a cosmic force based around gravity and the force of motion.[1] Conduits of the Strength Force obtain radically enhanced strength and durability. It also boasts a geokinetic/geothermic component as it often wreathed the users body in stone or fiery rock, as well as caused the earth to shift at their beck and call.[2] The Strength Force grants its conduits powers by striking them from below the earth's surface and imbuing them with its energy.[3]
During his time in the 25th Century, Hunter Zolomon studied the history books there and discovered that the Speed Force and its negative weren't the only cosmic forces in the multiverse. These other forces lay dormant due to a "Force Barrier." Zoom manipulated Barry Allen and Wally West into running fast enough to break said barrier, which allowed Zolomon to tap into the Speed, Sage, and Strength Forces.[4]
