The Horseless Headless Horsemann is one of the non-playable characters in Lego Dimensions 2: The Rise of Enoch, from the Team Fortress 2 franchise.
The presumed brother of Zepheniah Mann, Silas' history within the family is shrouded in mystery. What is known is that he was the co-owner of Zepheniah Mann & Sons.

He now roams Mann Manor as the Horseless Headless Horsemann, similarly to how Zepheniah haunts Harvest Event as a glowing blue spirit.
