Lash, displeased at Tobias Manning's criminal activities using information and equipment supplied by Chronos, decided to help Sheriff Ohiyesa Smith, the bounty hunter Jonah Hex and the masked hero El Diablo find a way to defeat him.
To that end, Lash volunteered to enter the town of Elkhorn, Oklahoma which was under the villain's control to find information about him and enticed him into a game of poker. After winning big, Lash found himself outgunned by Manning's advanced weaponry and arrested and summarily condemned by the villain. However, Lash was freed by Batman, Green Lantern and Wonder Woman who were inadvertently pulled into that era by Chronos who happened to be in an adjoining cell at that time of Lash's confinement.
Later, Lash and his contemporary fellows and the time travelers joined up to defeat Manning and succeeded.
Lash was last seen gaping with the other western heroes as the League members disappeared into a time portal in pursuit of Clinton.
