Density Control: Being imbued with the speed force, Block has the unique ability to slow down her atoms. In doing this, they become denser than steel and grant her invulnerability, super strength, and immobility.
Speed Force Conduit: Block is a speed force conduit, like the Flash. She is able to manipulate the speed force for a number of effects, she can possibly slow down other speedsters if not other people as well through physical touch, as she stopped the Top's ability and was able to hold Zoom in place in a headlock, she was able to stop the molecules around herself to make the air unbreakable.
A young Maori woman living in Melbourne, Australia, the woman dubbed the Human Block was once inexplicably struck by lightning and survived the incident. Unknown to her, this similar event had happened to many other individuals throughout time, and was in fact the speed force imbuing her with speed related abilities. In her then present time, 1957, Block acted as a side show attraction in a carnival. The prize of $1000 going to whoever could move her which was failed by many as she had manipulated her body density. One drunken man staggered onto the stage to accept her challenge, making her move by insulting her Maori heritage rather than physically moving her. Angered she immediately struck out at him and instigated a small brawl, tearing through the crowd before someone hastily drew their firearm on her and shot, only to find that not even bullets affected her. Before the now turned mob could attack her, Zoom accompanied by his newly recruited acolytes Folded Man and Magali appeared and teleported her outside of the carnival grounds. Being offered the chance to embrace her abilities and live as a godlike being after mastering them, she did not hesitate to join Zoom and his quest to kill the "evil" Flash.
